Instead, let it linger as a 'dead' source until the user chooses to fix the problem (though this should never really happen, the source module functions should be programmed to handle this scenario) Secondly, rename new_frame_ready to ready_async_frame, and fix a potential memory leak with it.

Simplify and extend callback/signalling system - Signals and dynamic callbacks now require declarations to be made before being used. What this does is allows us to get information about the functions dynamically which can be relayed to the user and plugins for future extended usage (this should have big implications later for scripting in particular, hopefully). - Reduced the number of types calldata uses from "everything I could think of" to simply integer, float, bool, pointer/object, string. Integer data is now stored as long long. Floats are now stored as doubles (check em). - Use a more consistent naming scheme for lexer error/warning macros. - Fixed a rather nasty bug where switching to an existing scene would cause it to increment sourceSceneRefs, which would mean that it would never end up never properly removing the source when the user clicks removed (stayed in limbo, obs_source_remove never got called)

Add 'update_properties' signal and obs_source_update_properties call obs_source_update_properties should be called by sources when property values change, e.g. a capture device source would use this when it detects a new capture device (in case its properties contain a list of available capture devices or similar)

Add optional source flags This moves the 'flags' variable from the obs_source_frame structure to the obs_source structure, and allows user flags to be set for a specific source. Having it set on the obs_source_frame structure didn't make much sense. OBS_SOURCE_UNBUFFERED makes it so that the source does not buffer its async video output in order to try to play it on time. In other words, frames are played as soon as possible after being received. Useful when you want a source to play back as quickly as possible (webcams, certain types of capture devices)

(API Change) Add support for multiple audio mixers API changed: -------------------------- void obs_output_set_audio_encoder( obs_output_t *output, obs_encoder_t *encoder); obs_encoder_t *obs_output_get_audio_encoder( const obs_output_t *output); obs_encoder_t *obs_audio_encoder_create( const char *id, const char *name, obs_data_t *settings); Changed to: -------------------------- /* 'idx' specifies the track index of the output */ void obs_output_set_audio_encoder( obs_output_t *output, obs_encoder_t *encoder, size_t idx); /* 'idx' specifies the track index of the output */ obs_encoder_t *obs_output_get_audio_encoder( const obs_output_t *output, size_t idx); /* 'mixer_idx' specifies the mixer index to capture audio from */ obs_encoder_t *obs_audio_encoder_create( const char *id, const char *name, obs_data_t *settings, size_t mixer_idx); Overview -------------------------- This feature allows multiple audio mixers to be used at a time. This capability was able to be added with surprisingly very little extra overhead. Audio will not be mixed unless it's assigned to a specific mixer, and mixers will not mix unless they have an active mix connection. Mostly this will be useful for being able to separate out specific audio for recording versus streaming, but will also be useful for certain streaming services that support multiple audio streams via RTMP. I didn't want to use a variable amount of mixers due to the desire to reduce heap allocations, so currently I set the limit to 4 simultaneous mixers; this number can be increased later if needed, but honestly I feel like it's just the right number to use. Sources: Sources can now specify which audio mixers their audio is mixed to; this can be a single mixer or multiple mixers at a time. The obs_source_set_audio_mixers function sets the audio mixer which an audio source applies to. For example, 0xF would mean that the source applies to all four mixers. Audio Encoders: Audio encoders now must specify which specific audio mixer they use when they encode audio data. Outputs: Outputs that use encoders can now support multiple audio tracks at once if they have the OBS_OUTPUT_MULTI_TRACK capability flag set. This is mostly only useful for certain types of RTMP transmissions, though may be useful for file formats that support multiple audio tracks as well later on.

libobs: Implement transition sources Transition sources are implemented by registering a source type as OBS_SOURCE_TYPE_TRANSITION. They're automatically marked as video composite sources, and video_render/audio_render callbacks must be set when registering the source. get_width and get_height callbacks are unused for these types of sources, as transitions automatically handle width/height behind the scenes with the transition settings. In the video_render callback, the helper function obs_transition_video_render is used to assist in automatically processing and rendering the audio. A render callback is passed to the function, which in turn passes to/from textures that are automatically rendered in the back-end. Similarly, in the audio_render callback, the helper function obs_transition_audio_render is used to assist in automatically processing and rendering the audio. Two mix callbacks are used to handle how the source/destination sources are mixed together. To ensure the best possible quality, audio processing is per-sample. Transitions can be set to automatically resize, or they can be set to have a fixed size. Sources within transitions can be made to scale to the transition size (with or without aspect ratio), or to not scale unless they're bigger than the transition. They can have a specific alignment within the transition, or they just default to top-left. These features are implemented for the purpose of extending transitions to also act as "switch" sources later, where you can switch to/from two different sources using the transition animation. Planned (but not yet implemented and lower priority) features: - "Switch" transitions which allow the ability to switch back and forth between two sources with a transitioning animation without discarding the references - Easing options to allow the option to transition with a bezier or custom curve - Manual transitioning to allow the front-end/user to manually control the transition offset

libobs: Add services API, reduce repeated code Add API for streaming services. The services API simplifies the creation of custom service features and user interface. Custom streaming services later on will be able to do things such as: - Be able to use service-specific APIs via modules, allowing a more direct means of communicating with the service and requesting or setting service-specific information - Get URL/stream key via other means of authentication such as OAuth, or be able to build custom URLs for services that require that sort of thing. - Query information (such as viewer count, chat, follower notifications, and other information) - Set channel information (such as current game, current channel title, activating commercials) Also, I reduce some repeated code that was used for all libobs objects. This includes the name of the object, the private data, settings, as well as the signal and procedure handlers. I also switched to using linked lists for the global object lists, rather than using an array of pointers (you could say it was.. pointless.) ..Anyway, the linked list info is also stored in the shared context data structure.

libobs: Implement composite sources (skip) (Note: This commit breaks libobs compilation. Skip if bisecting) Adds a "composite" source type which is used for sources that composite one or more sub-sources. The audio_render callback is called for composite sources to allow those types of sources to do custom processing of the audio of its sub-sources.

Add more volume options Added a "master" volume for the entire audio subsystem. Also, added a "presentation" volume for both the master volume and for each invidiaul source. The presentation volume is used to control things like transitioning volumes, preventing sources from outputting any audio when they're inactive, as well as some other uses in the future.

libobs: Implement new audio subsystem The new audio subsystem fixes two issues: - First Primary issue it fixes is the ability for parent sources to intercept the audio of child sources, and do custom processing on them. The main reason for this was the ability to do custom cross-fading in transitions, but it's also useful for things such as side-chain effects, applying audio effects to entire scenes, applying scene-specific audio filters on sub-sources, and other such possibilities. - The secondary issue that needed fixing was audio buffering. Previously, audio buffering was always a fixed buffer size, so it would always have exactly a certain number of milliseconds of audio buffering (and thus output delay). Instead, it now dynamically increases audio buffering only as necessary, minimizing output delay, and removing the need for users to have to worry about an audio buffering setting. The new design makes it so that audio from the leaves of the scene graph flow to the root nodes, and can be intercepted by parent sources. Each audio source handles its own buffering, and each audio tick a specific number of audio frames are popped from the front of the circular buffer on each audio source. Composite sources (such as scenes) can access the audio for child sources and do custom processing or mixing on that audio. Composite sources use the audio_render callback of sources to do synchronous or deferred audio processing per audio tick. Things like scenes now mix audio from their sub-sources.

libobs: Add services API, reduce repeated code Add API for streaming services. The services API simplifies the creation of custom service features and user interface. Custom streaming services later on will be able to do things such as: - Be able to use service-specific APIs via modules, allowing a more direct means of communicating with the service and requesting or setting service-specific information - Get URL/stream key via other means of authentication such as OAuth, or be able to build custom URLs for services that require that sort of thing. - Query information (such as viewer count, chat, follower notifications, and other information) - Set channel information (such as current game, current channel title, activating commercials) Also, I reduce some repeated code that was used for all libobs objects. This includes the name of the object, the private data, settings, as well as the signal and procedure handlers. I also switched to using linked lists for the global object lists, rather than using an array of pointers (you could say it was.. pointless.) ..Anyway, the linked list info is also stored in the shared context data structure.

libobs: Mark filters as private (band-aid fix) This patch fixes a specific crash where if the user named a filter the same name as an input source that already existed in the system, scene item loading code could find the filter with the same name instead of the source, and mistakenly use it as the scene item's source directly. This would cause a crash when trying to render that filter as a regular source. Marking filters as private is a temporary and simple workaround to the solution. Filters are currently not meant to be found via the main enumeration/search functions, which is a design flaw (lack of consistency). In future major API revisions of libobs, filters should be reworked to act as sources, with the sources they filter as sub-sources ideally. Additionally, the concept of "private context objects" and "primary lists of context objects" in the back-end should probably also be removed, allowing the font-end (or optional separate API layers) to control all primary lists of obs context objects. These minor issues that occur ultimately stem from API design flaws which need to be corrected.

Improve safety for settings usage - Add 'set_default' functions to obs-data.*. These functions ensure that a paramter exists and that the parameter is of a specific type. If not, it will create or overwrite the value with the default setting instead. These functions are meant to be explicitly called before using any of the 'get' functions. The reason why it was designed this way is to encourage defaults to be set in a single place/function. For example, ideal usage is to create one function for your data, "set_my_defaults(obs_data_t data)", set all the default values within that function, and then call that function on create/update, that way all defaults are centralized to a single place. - Ensure that data passed to sources/encoders/outputs/etc is always valid, and not a null value. - While I'm remembering, fix a few defaults of the main program config file data.

Had this crash happen to me when creating a WASAPI output source, the create callback of the WASAPI source creates a thread which outputs audio, and that thread managed to call obs_source_output_audio before the obs_source_init function was called, which in turn caused it to try to use a null mutex.

libobs: Add services API, reduce repeated code Add API for streaming services. The services API simplifies the creation of custom service features and user interface. Custom streaming services later on will be able to do things such as: - Be able to use service-specific APIs via modules, allowing a more direct means of communicating with the service and requesting or setting service-specific information - Get URL/stream key via other means of authentication such as OAuth, or be able to build custom URLs for services that require that sort of thing. - Query information (such as viewer count, chat, follower notifications, and other information) - Set channel information (such as current game, current channel title, activating commercials) Also, I reduce some repeated code that was used for all libobs objects. This includes the name of the object, the private data, settings, as well as the signal and procedure handlers. I also switched to using linked lists for the global object lists, rather than using an array of pointers (you could say it was.. pointless.) ..Anyway, the linked list info is also stored in the shared context data structure.

libobs: Use reference counting with source frames When a frame is processed by a filter, it comes directly from the source's video frame cache. However, if a filter is using or processing those frames for whatever reason, there would be no guarantee that the frames would persist during processing, and frames could eventually be deallocated unexpected, for example when the resolution or format changes. So the solution is to implement simple reference counting for the frames so that the frames will exist until they have been released by any source or filter that's using them.

libobs: Implement transition sources Transition sources are implemented by registering a source type as OBS_SOURCE_TYPE_TRANSITION. They're automatically marked as video composite sources, and video_render/audio_render callbacks must be set when registering the source. get_width and get_height callbacks are unused for these types of sources, as transitions automatically handle width/height behind the scenes with the transition settings. In the video_render callback, the helper function obs_transition_video_render is used to assist in automatically processing and rendering the audio. A render callback is passed to the function, which in turn passes to/from textures that are automatically rendered in the back-end. Similarly, in the audio_render callback, the helper function obs_transition_audio_render is used to assist in automatically processing and rendering the audio. Two mix callbacks are used to handle how the source/destination sources are mixed together. To ensure the best possible quality, audio processing is per-sample. Transitions can be set to automatically resize, or they can be set to have a fixed size. Sources within transitions can be made to scale to the transition size (with or without aspect ratio), or to not scale unless they're bigger than the transition. They can have a specific alignment within the transition, or they just default to top-left. These features are implemented for the purpose of extending transitions to also act as "switch" sources later, where you can switch to/from two different sources using the transition animation. Planned (but not yet implemented and lower priority) features: - "Switch" transitions which allow the ability to switch back and forth between two sources with a transitioning animation without discarding the references - Easing options to allow the option to transition with a bezier or custom curve - Manual transitioning to allow the front-end/user to manually control the transition offset

If new frames come in that are of a different format/width/height, it'll just clear the cache. This is a fairly important optimization.

Deinterlacing is set via obs_source_set_deinterlace_mode and obs_source_set_deinterlace_field_order. This was implemented in to the core itself because deinterlacing should happen before effect filters are processed, but after async filters are processed. If this were added as a filter, there is the possibility that a different filter is processed before deinterlacing, which could mess with the result. It was also a bit easier to implement this way due to the fact that that deinterlacing may need to have access to the previous async frame. Effects were split in to separate files to reduce load time (especially for yadif shaders which take a significant amount of time to compile).

Add planar audio support, improve test output - Add planar audio support. FFmpeg and libav use planar audio for many encoders, so it was somewhat necessary to add support in libobs itself. - Improve/adjust FFmpeg test output plugin. The exports were somewhat messed up (making me rethink how exports should be done). Not yet functional; it handles video properly, but it still does not handle audio properly. - Improve planar video code. The planar video code was not properly accounting for row sizes for each plane. Specifying row sizes for each plane has now been added. This will also make it more compatible with FFmpeg/libav. - Fixed a bug where callbacks wouldn't create properly in audio-io and video-io code. - Implement 'blogva' function to allow for va_list usage with libobs logging.

libobs: Implement transition sources Transition sources are implemented by registering a source type as OBS_SOURCE_TYPE_TRANSITION. They're automatically marked as video composite sources, and video_render/audio_render callbacks must be set when registering the source. get_width and get_height callbacks are unused for these types of sources, as transitions automatically handle width/height behind the scenes with the transition settings. In the video_render callback, the helper function obs_transition_video_render is used to assist in automatically processing and rendering the audio. A render callback is passed to the function, which in turn passes to/from textures that are automatically rendered in the back-end. Similarly, in the audio_render callback, the helper function obs_transition_audio_render is used to assist in automatically processing and rendering the audio. Two mix callbacks are used to handle how the source/destination sources are mixed together. To ensure the best possible quality, audio processing is per-sample. Transitions can be set to automatically resize, or they can be set to have a fixed size. Sources within transitions can be made to scale to the transition size (with or without aspect ratio), or to not scale unless they're bigger than the transition. They can have a specific alignment within the transition, or they just default to top-left. These features are implemented for the purpose of extending transitions to also act as "switch" sources later, where you can switch to/from two different sources using the transition animation. Planned (but not yet implemented and lower priority) features: - "Switch" transitions which allow the ability to switch back and forth between two sources with a transitioning animation without discarding the references - Easing options to allow the option to transition with a bezier or custom curve - Manual transitioning to allow the front-end/user to manually control the transition offset

libobs: Implement new audio subsystem The new audio subsystem fixes two issues: - First Primary issue it fixes is the ability for parent sources to intercept the audio of child sources, and do custom processing on them. The main reason for this was the ability to do custom cross-fading in transitions, but it's also useful for things such as side-chain effects, applying audio effects to entire scenes, applying scene-specific audio filters on sub-sources, and other such possibilities. - The secondary issue that needed fixing was audio buffering. Previously, audio buffering was always a fixed buffer size, so it would always have exactly a certain number of milliseconds of audio buffering (and thus output delay). Instead, it now dynamically increases audio buffering only as necessary, minimizing output delay, and removing the need for users to have to worry about an audio buffering setting. The new design makes it so that audio from the leaves of the scene graph flow to the root nodes, and can be intercepted by parent sources. Each audio source handles its own buffering, and each audio tick a specific number of audio frames are popped from the front of the circular buffer on each audio source. Composite sources (such as scenes) can access the audio for child sources and do custom processing or mixing on that audio. Composite sources use the audio_render callback of sources to do synchronous or deferred audio processing per audio tick. Things like scenes now mix audio from their sub-sources.

libobs: Do not use signals with audio capture/controls (Note: This commit also modifies UI) Instead of using signals, use designated callback lists for audio capture and audio control helpers. Signals aren't suitable here due to the fact that signals aren't meant for things that happen every frame or things that happen every time audio/video is received. Also prevents audio from being allocated every time these functions are called due to the calldata structure.

libobs: Add frame caching for async video sources The temporary unoptimized code we were using before just completely allocated a new copy of each frame every single time a new async frame was output by the source plugin. This just creates a cache of frames as needed for the current format/width/height to minimize the allocation and deallocation. If new frames come in that are of a different format/width/height, it'll just clear the cache. This is a fairly important optimization.

Signals aren't suitable here due to the fact that signals aren't meant for things that happen every frame or things that happen every time audio/video is received. Also prevents audio from being allocated every time these functions are called due to the calldata structure.

libobs: Add services API, reduce repeated code Add API for streaming services. The services API simplifies the creation of custom service features and user interface. Custom streaming services later on will be able to do things such as: - Be able to use service-specific APIs via modules, allowing a more direct means of communicating with the service and requesting or setting service-specific information - Get URL/stream key via other means of authentication such as OAuth, or be able to build custom URLs for services that require that sort of thing. - Query information (such as viewer count, chat, follower notifications, and other information) - Set channel information (such as current game, current channel title, activating commercials) Also, I reduce some repeated code that was used for all libobs objects. This includes the name of the object, the private data, settings, as well as the signal and procedure handlers. I also switched to using linked lists for the global object lists, rather than using an array of pointers (you could say it was.. pointless.) ..Anyway, the linked list info is also stored in the shared context data structure.

(API Change) Remove pointers from all typedefs Typedef pointers are unsafe. If you do: typedef struct bla *bla_t; then you cannot use it as a constant, such as: const bla_t, because that constant will be to the pointer itself rather than to the underlying data. I admit this was a fundamental mistake that must be corrected. All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead.

Add source properties window (very preliminary) - Add a properties window for sources so that you can now actually edit the settings for sources. Also, display the source by itself in the window (Note: not working on mac, and possibly not working on linux). When changing the settings for a source, it will call obs_source_update on that source when you have modified any values automatically. - Add a properties 'widget', eventually I want to turn this in to a regular nice properties view like you'd see in the designer, but right now it just uses a form layout in a QScrollArea with regular controls to display the properties. It's clunky but works for the time being. - Make it so that swap chains and the main graphics subsystem will automatically use at least one backbuffer if none was specified - Fix bug where displays weren't added to the main display array - Make it so that you can get the properties of a source via the actual pointer of a source/encoder/output in addition to being able to look up properties via identifier. - When registering source types, check for required functions (wasn't doing it before). getheight/getwidth should not be optional if it's a video source as well. - Add an RAII OBSObj wrapper to obs.hpp for non-reference-counted libobs pointers - Add an RAII OBSSignal wrapper to obs.hpp for libobs signals to automatically disconnect them on destruction - Move the "scale and center" calculation in window-basic-main.cpp to its own function and in its own source file - Add an 'update' callback to WASAPI audio sources

(API Change) Remove pointers from all typedefs Typedef pointers are unsafe. If you do: typedef struct bla *bla_t; then you cannot use it as a constant, such as: const bla_t, because that constant will be to the pointer itself rather than to the underlying data. I admit this was a fundamental mistake that must be corrected. All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead. This does not break ABI though, which is pretty nice.

libobs: Add services API, reduce repeated code Add API for streaming services. The services API simplifies the creation of custom service features and user interface. Custom streaming services later on will be able to do things such as: - Be able to use service-specific APIs via modules, allowing a more direct means of communicating with the service and requesting or setting service-specific information - Get URL/stream key via other means of authentication such as OAuth, or be able to build custom URLs for services that require that sort of thing. - Query information (such as viewer count, chat, follower notifications, and other information) - Set channel information (such as current game, current channel title, activating commercials) Also, I reduce some repeated code that was used for all libobs objects. This includes the name of the object, the private data, settings, as well as the signal and procedure handlers. I also switched to using linked lists for the global object lists, rather than using an array of pointers (you could say it was.. pointless.) ..Anyway, the linked list info is also stored in the shared context data structure.

obs_properties_apply_settings(props, source->context.settings);
Improve properties API Improve the properties API so that it can actually respond somewhat to user input. Maybe later this might be further improved or replaced with something script-based. When creating a property, you can now add a callback to that property that notifies when the property has been changed in the user interface. Return true if you want the properties to be refreshed, or false if not. Though now that I think about it I doubt there would ever be a case where you would have this callback and *not* refresh the properties. Regardless, this allows functions to change the values of properties or settings, or enable/disable/hide other property controls from view dynamically.
2014-04-04 00:30:37 -07:00
return props;
}
Add source properties window (very preliminary) - Add a properties window for sources so that you can now actually edit the settings for sources. Also, display the source by itself in the window (Note: not working on mac, and possibly not working on linux). When changing the settings for a source, it will call obs_source_update on that source when you have modified any values automatically. - Add a properties 'widget', eventually I want to turn this in to a regular nice properties view like you'd see in the designer, but right now it just uses a form layout in a QScrollArea with regular controls to display the properties. It's clunky but works for the time being. - Make it so that swap chains and the main graphics subsystem will automatically use at least one backbuffer if none was specified - Fix bug where displays weren't added to the main display array - Make it so that you can get the properties of a source via the actual pointer of a source/encoder/output in addition to being able to look up properties via identifier. - When registering source types, check for required functions (wasn't doing it before). getheight/getwidth should not be optional if it's a video source as well. - Add an RAII OBSObj wrapper to obs.hpp for non-reference-counted libobs pointers - Add an RAII OBSSignal wrapper to obs.hpp for libobs signals to automatically disconnect them on destruction - Move the "scale and center" calculation in window-basic-main.cpp to its own function and in its own source file - Add an 'update' callback to WASAPI audio sources

(API Change) Use const params where applicable This Fixes a minor flaw with the API where data had to always be mutable to be usable by the API. Functions that do not modify the fundamental underlying data of a structure should be marked as constant, both for safety and to signify that the parameter is input only and will not be modified by the function using it.

Implement RTMP module (still needs drop code) - Implement the RTMP output module. This time around, we just use a simple FLV muxer, then just write to the stream with RTMP_Write. Easy and effective. - Fix the FLV muxer, the muxer now outputs proper FLV packets. - Output API: * When using encoders, automatically interleave encoded packets before sending it to the output. * Pair encoders and have them automatically wait for the other to start to ensure sync. * Change 'obs_output_signal_start_fail' to 'obs_output_signal_stop' because it was a bit confusing, and doing this makes a lot more sense for outputs that need to stop suddenly (disconnections/etc). - Encoder API: * Remove some unnecessary encoder functions from the actual API and make them internal. Most of the encoder functions are handled automatically by outputs anyway, so there's no real need to expose them and end up inadvertently confusing plugin writers. * Have audio encoders wait for the video encoder to get a frame, then start at the exact data point that the first video frame starts to ensure the most accrate sync of video/audio possible. * Add a required 'frame_size' callback for audio encoders that returns the expected number of frames desired to encode with. This way, the libobs encoder API can handle the circular buffering internally automatically for the encoder modules, so encoder writers don't have to do it themselves. - Fix a few bugs in the serializer interface. It was passing the wrong variable for the data in a few cases. - If a source has video, make obs_source_update defer the actual update callback until the tick function is called to prevent threading issues.

Integer data is now stored as long long. Floats are now stored as doubles (check em). - Use a more consistent naming scheme for lexer error/warning macros. - Fixed a rather nasty bug where switching to an existing scene would cause it to increment sourceSceneRefs, which would mean that it would never end up never properly removing the source when the user clicks removed (stayed in limbo, obs_source_remove never got called)

Now, for things like transition sources, they have a means of knowing when they have actually been "activated" so they can initiate their sequence. A source is now only considered "active" when it's being displayed by the main view. When a source is shown in the main view, the activate callback/signal is triggered. When it's no longer being displayed by the main view, deactivate callback/signal is triggered. When a source is just generally visible to see by any view, the show callback/signal is triggered. If it's no longer visible by any views, then the hide callback/signal is triggered. Presentation volume will now only be active when a source is active in the main view rather than also in auxilary views. Also fix a potential bug where parents wouldn't properly increment or decrement all the activation references of a child source when a child was added or removed.

Implement source activation/deactivation Now sources will be properly activated and deactivated when they are in use or not in use. Had to figure out a way to handle child sources, and children of children, just ended up implementing simple functions that parents use to signal adding/removal to help with hierarchial activation and deactivation of child sources. To prevent the source activate/deactivate callbacks from being called more than once, added an activation reference counter. The first increment will call the activate callback, and the last decrement will call the deactivate callback. Added "source-activate" and "source-deactivate" signals to the main obs signal handler, and "activate" and "deactivate" to individual source signal handlers. Also, fixed the main window so it properly selects a source when the current active scene has been changed.

(API Change) Remove pointers from all typedefs Typedef pointers are unsafe. If you do: typedef struct bla *bla_t; then you cannot use it as a constant, such as: const bla_t, because that constant will be to the pointer itself rather than to the underlying data. I admit this was a fundamental mistake that must be corrected. All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead. This does not break ABI though, which is pretty nice.

Implement volume handling - Remove obs_source::type because it became redundant now that the type is always stored in the obs_source::info variable. - Apply presentation volumes of 1.0 and 0.0 to sources when they activate/deactivate, respectively. It also applies that presentation volume to all sub-sources, with exception of transition sources. Transition sources must apply presentation volume manually to their sub-sources with the new transition functions below. - Add a "transition_volume" variable to obs_source structure, and add three functions for handling volume for transitions: * obs_transition_begin_frame * obs_source_set_transition_vol * obs_transition_end_frame Because the to/from targets of a transition source might both contain some of the same sources, handling the transitioning of volumes for that specific situation becomes an issue. So for transitions, instead of modifying the presentation volumes directly for both sets of sources, we do this: - First, call obs_transition_begin_frame at the beginning of each transition frame, which will reset transition volumes for all sub-sources to 0. Presentation volumes remain unchanged. - Call obs_source_set_transition_vol on each sub-source, which will then add the volume to the transition volume for each source in that source's tree. Presentation volumes still remain unchanged. - Then you call obs_trandition_end_frame when complete, which will then finally set the presentation volumes to the transition volumes. For example, let's say that there's one source that's within both the "transitioning from" sources and "transition to" sources. It would add both the fade in and fade out volumes to that source, and then when the frame is complete, it would set the presentation volume to the sum of those two values, rather than set the presentation volume for that same source twice which would cause weird volume jittering and also set the wrong values.

Separate source activation for main/aux views Split off activate to activate and show callbacks, and split off deactivate to deactivate and hide callbacks. Sources didn't previously have a means to know whether it was actually being displayed in the main view or just happened to be visible somewhere. Now, for things like transition sources, they have a means of knowing when they have actually been "activated" so they can initiate their sequence. A source is now only considered "active" when it's being displayed by the main view. When a source is shown in the main view, the activate callback/signal is triggered. When it's no longer being displayed by the main view, deactivate callback/signal is triggered. When a source is just generally visible to see by any view, the show callback/signal is triggered. If it's no longer visible by any views, then the hide callback/signal is triggered. Presentation volume will now only be active when a source is active in the main view rather than also in auxilary views. Also fix a potential bug where parents wouldn't properly increment or decrement all the activation references of a child source when a child was added or removed.

(API Change) Remove pointers from all typedefs Typedef pointers are unsafe. If you do: typedef struct bla *bla_t; then you cannot use it as a constant, such as: const bla_t, because that constant will be to the pointer itself rather than to the underlying data. I admit this was a fundamental mistake that must be corrected. All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead. This does not break ABI though, which is pretty nice.

libobs: Swap async source frames in tick Async frames are only swapping when rendering, or when not visible. This is a flawed design due to the fact that there are certain circumstances where the source is neither visible nor currently rendering. This is what caused a memory leak when scene items were marked as invisible, because if a source has an async child source and decides not to render that source for whatever reason, the child source would not process the async frames at all, and the cache would just grow. To fix this, simply moving the async frame cycle to tick fixes the issue due to the fact that tick is always called regardless of circumstance.

libobs: Implement transition sources Transition sources are implemented by registering a source type as OBS_SOURCE_TYPE_TRANSITION. They're automatically marked as video composite sources, and video_render/audio_render callbacks must be set when registering the source. get_width and get_height callbacks are unused for these types of sources, as transitions automatically handle width/height behind the scenes with the transition settings. In the video_render callback, the helper function obs_transition_video_render is used to assist in automatically processing and rendering the audio. A render callback is passed to the function, which in turn passes to/from textures that are automatically rendered in the back-end. Similarly, in the audio_render callback, the helper function obs_transition_audio_render is used to assist in automatically processing and rendering the audio. Two mix callbacks are used to handle how the source/destination sources are mixed together. To ensure the best possible quality, audio processing is per-sample. Transitions can be set to automatically resize, or they can be set to have a fixed size. Sources within transitions can be made to scale to the transition size (with or without aspect ratio), or to not scale unless they're bigger than the transition. They can have a specific alignment within the transition, or they just default to top-left. These features are implemented for the purpose of extending transitions to also act as "switch" sources later, where you can switch to/from two different sources using the transition animation. Planned (but not yet implemented and lower priority) features: - "Switch" transitions which allow the ability to switch back and forth between two sources with a transitioning animation without discarding the references - Easing options to allow the option to transition with a bezier or custom curve - Manual transitioning to allow the front-end/user to manually control the transition offset

libobs: Add deinterlacing API functions Adds deinterlacing API functions. Both standard and 2x variants are supported. Deinterlacing is set via obs_source_set_deinterlace_mode and obs_source_set_deinterlace_field_order. This was implemented in to the core itself because deinterlacing should happen before effect filters are processed, but after async filters are processed. If this were added as a filter, there is the possibility that a different filter is processed before deinterlacing, which could mess with the result. It was also a bit easier to implement this way due to the fact that that deinterlacing may need to have access to the previous async frame. Effects were split in to separate files to reduce load time (especially for yadif shaders which take a significant amount of time to compile).

Implement RTMP module (still needs drop code) - Implement the RTMP output module. This time around, we just use a simple FLV muxer, then just write to the stream with RTMP_Write. Easy and effective. - Fix the FLV muxer, the muxer now outputs proper FLV packets. - Output API: * When using encoders, automatically interleave encoded packets before sending it to the output. * Pair encoders and have them automatically wait for the other to start to ensure sync. * Change 'obs_output_signal_start_fail' to 'obs_output_signal_stop' because it was a bit confusing, and doing this makes a lot more sense for outputs that need to stop suddenly (disconnections/etc). - Encoder API: * Remove some unnecessary encoder functions from the actual API and make them internal. Most of the encoder functions are handled automatically by outputs anyway, so there's no real need to expose them and end up inadvertently confusing plugin writers. * Have audio encoders wait for the video encoder to get a frame, then start at the exact data point that the first video frame starts to ensure the most accrate sync of video/audio possible. * Add a required 'frame_size' callback for audio encoders that returns the expected number of frames desired to encode with. This way, the libobs encoder API can handle the circular buffering internally automatically for the encoder modules, so encoder writers don't have to do it themselves. - Fix a few bugs in the serializer interface. It was passing the wrong variable for the data in a few cases. - If a source has video, make obs_source_update defer the actual update callback until the tick function is called to prevent threading issues.

Revamp API and start using doxygen The API used to be designed in such a way to where it would expect exports for each individual source/output/encoder/etc. You would export functions for each and it would automatically load those functions based on a specific naming scheme from the module. The idea behind this was that I wanted to limit the usage of structures in the API so only functions could be used. It was an interesting idea in theory, but this idea turned out to be flawed in a number of ways: 1.) Requiring exports to create sources/outputs/encoders/etc meant that you could not create them by any other means, which meant that things like faruton's .net plugin would become difficult. 2.) Export function declarations could not be checked, therefore if you created a function with the wrong parameters and parameter types, the compiler wouldn't know how to check for that. 3.) Required overly complex load functions in libobs just to handle it. It makes much more sense to just have a load function that you call manually. Complexity is the bane of all good programs. 4.) It required that you have functions of specific names, which looked and felt somewhat unsightly. So, to fix these issues, I replaced it with a more commonly used API scheme, seen commonly in places like kernels and typical C libraries with abstraction. You simply create a structure that contains the callback definitions, and you pass it to a function to register that definition (such as obs_register_source), which you call in the obs_module_load of the module. It will also automatically check the structure size and ensure that it only loads the required values if the structure happened to add new values in an API change. The "main" source file for each module must include obs-module.h, and must use OBS_DECLARE_MODULE() within that source file. Also, started writing some doxygen documentation in to the main library headers. Will add more detailed documentation as I go.

Revamp API and start using doxygen The API used to be designed in such a way to where it would expect exports for each individual source/output/encoder/etc. You would export functions for each and it would automatically load those functions based on a specific naming scheme from the module. The idea behind this was that I wanted to limit the usage of structures in the API so only functions could be used. It was an interesting idea in theory, but this idea turned out to be flawed in a number of ways: 1.) Requiring exports to create sources/outputs/encoders/etc meant that you could not create them by any other means, which meant that things like faruton's .net plugin would become difficult. 2.) Export function declarations could not be checked, therefore if you created a function with the wrong parameters and parameter types, the compiler wouldn't know how to check for that. 3.) Required overly complex load functions in libobs just to handle it. It makes much more sense to just have a load function that you call manually. Complexity is the bane of all good programs. 4.) It required that you have functions of specific names, which looked and felt somewhat unsightly. So, to fix these issues, I replaced it with a more commonly used API scheme, seen commonly in places like kernels and typical C libraries with abstraction. You simply create a structure that contains the callback definitions, and you pass it to a function to register that definition (such as obs_register_source), which you call in the obs_module_load of the module. It will also automatically check the structure size and ensure that it only loads the required values if the structure happened to add new values in an API change. The "main" source file for each module must include obs-module.h, and must use OBS_DECLARE_MODULE() within that source file. Also, started writing some doxygen documentation in to the main library headers. Will add more detailed documentation as I go.

obs-source.c: Fix a few potential concerns First, if the private data of the source fails to be created, then do not destroy the source. If the source is destroyed, all the user's data associated with that source is lost, which could end up being a potential problem. Instead, let it linger as a 'dead' source until the user chooses to fix the problem (though this should never really happen, the source module functions should be programmed to handle this scenario) Secondly, rename new_frame_ready to ready_async_frame, and fix a potential memory leak with it.

libobs: Add services API, reduce repeated code Add API for streaming services. The services API simplifies the creation of custom service features and user interface. Custom streaming services later on will be able to do things such as: - Be able to use service-specific APIs via modules, allowing a more direct means of communicating with the service and requesting or setting service-specific information - Get URL/stream key via other means of authentication such as OAuth, or be able to build custom URLs for services that require that sort of thing. - Query information (such as viewer count, chat, follower notifications, and other information) - Set channel information (such as current game, current channel title, activating commercials) Also, I reduce some repeated code that was used for all libobs objects. This includes the name of the object, the private data, settings, as well as the signal and procedure handlers. I also switched to using linked lists for the global object lists, rather than using an array of pointers (you could say it was.. pointless.) ..Anyway, the linked list info is also stored in the shared context data structure.

libobs: Add deinterlacing API functions Adds deinterlacing API functions. Both standard and 2x variants are supported. Deinterlacing is set via obs_source_set_deinterlace_mode and obs_source_set_deinterlace_field_order. This was implemented in to the core itself because deinterlacing should happen before effect filters are processed, but after async filters are processed. If this were added as a filter, there is the possibility that a different filter is processed before deinterlacing, which could mess with the result. It was also a bit easier to implement this way due to the fact that that deinterlacing may need to have access to the previous async frame. Effects were split in to separate files to reduce load time (especially for yadif shaders which take a significant amount of time to compile).

Implement output, improve video/audio subsystems - Fill in the rest of the FFmpeg test output code for testing so it actually properly outputs data. - Improve the main video subsystem to be a bit more optimal and automatically output I420 or NV12 if needed. - Fix audio subsystem insertation and byte calculation. Now it will seamlessly insert new audio data in to the audio stream based upon its timestamp value. (Be extremely cautious when using floating point calculations for important things like this, and always round your values and check your values) - Use 32 byte alignment in case of future optimizations and export a function to get the current alignment. - Make os_sleepto_ns return true if slept, false if the time has already been passed before the call. - Fix sinewave output so that it actually properly calculates a middle C sinewave. - Change the use of row_bytes to linesize (also makes it a bit more consistent with FFmpeg's naming as well)

libobs: Implement new audio subsystem The new audio subsystem fixes two issues: - First Primary issue it fixes is the ability for parent sources to intercept the audio of child sources, and do custom processing on them. The main reason for this was the ability to do custom cross-fading in transitions, but it's also useful for things such as side-chain effects, applying audio effects to entire scenes, applying scene-specific audio filters on sub-sources, and other such possibilities. - The secondary issue that needed fixing was audio buffering. Previously, audio buffering was always a fixed buffer size, so it would always have exactly a certain number of milliseconds of audio buffering (and thus output delay). Instead, it now dynamically increases audio buffering only as necessary, minimizing output delay, and removing the need for users to have to worry about an audio buffering setting. The new design makes it so that audio from the leaves of the scene graph flow to the root nodes, and can be intercepted by parent sources. Each audio source handles its own buffering, and each audio tick a specific number of audio frames are popped from the front of the circular buffer on each audio source. Composite sources (such as scenes) can access the audio for child sources and do custom processing or mixing on that audio. Composite sources use the audio_render callback of sources to do synchronous or deferred audio processing per audio tick. Things like scenes now mix audio from their sub-sources.

If audio timestamps are within the operating system timing threshold, always use those values directly as a timestamp, and do not apply the regular jump checks and timing adjustments that normally occur. This potentially fixes an issue with plugins that use OS timestamps directly as timestamp values for their audio samples, and bypasses the timing conversions to system time for the audio line and uses it directly as the timestamp value. It prevents those calculations from potentially affecting the audio timestamp value when OS timestamps are used. For example, if the first set of audio samples from the audio source came in delayed, while the subsequent samples were not delayed, those first samples could have potentially inadvertently triggered the timing adjustments, which would affect all subsequent audio samples.

If both audio and video are present, it will increment a reference counter if video timestamps invalidate, and decrement the reference counter when the audio timestamps invalidate. When the reference counter is not 0, it will not send audio as the audio will have invalid timing. What this does is it ensures audio data will never go out of bounds in relation to the video, and waits for both audio and video timestamps to "jump" together before resuming audio. - Moved async video frame timing adjustment code into obs_source_getframe instead so it's automatically handled whenever called. - Removed the 'audio wait buffer' as it was an unnecessary complexity that could have had problems in the future. Instead, audio will not be added until video starts for sources that have both async audio/video.

libobs: Implement new audio subsystem The new audio subsystem fixes two issues: - First Primary issue it fixes is the ability for parent sources to intercept the audio of child sources, and do custom processing on them. The main reason for this was the ability to do custom cross-fading in transitions, but it's also useful for things such as side-chain effects, applying audio effects to entire scenes, applying scene-specific audio filters on sub-sources, and other such possibilities. - The secondary issue that needed fixing was audio buffering. Previously, audio buffering was always a fixed buffer size, so it would always have exactly a certain number of milliseconds of audio buffering (and thus output delay). Instead, it now dynamically increases audio buffering only as necessary, minimizing output delay, and removing the need for users to have to worry about an audio buffering setting. The new design makes it so that audio from the leaves of the scene graph flow to the root nodes, and can be intercepted by parent sources. Each audio source handles its own buffering, and each audio tick a specific number of audio frames are popped from the front of the circular buffer on each audio source. Composite sources (such as scenes) can access the audio for child sources and do custom processing or mixing on that audio. Composite sources use the audio_render callback of sources to do synchronous or deferred audio processing per audio tick. Things like scenes now mix audio from their sub-sources.

If both audio and video are present, it will increment a reference counter if video timestamps invalidate, and decrement the reference counter when the audio timestamps invalidate. When the reference counter is not 0, it will not send audio as the audio will have invalid timing. What this does is it ensures audio data will never go out of bounds in relation to the video, and waits for both audio and video timestamps to "jump" together before resuming audio. - Moved async video frame timing adjustment code into obs_source_getframe instead so it's automatically handled whenever called. - Removed the 'audio wait buffer' as it was an unnecessary complexity that could have had problems in the future. Instead, audio will not be added until video starts for sources that have both async audio/video. Audio could have buffered for too long of a time anyway, who knows what devices are going to do. - Fixed a minor conversion warning in audio-io.c

What this does is it ensures audio data will never go out of bounds in relation to the video, and waits for both audio and video timestamps to "jump" together before resuming audio. - Moved async video frame timing adjustment code into obs_source_getframe instead so it's automatically handled whenever called. - Removed the 'audio wait buffer' as it was an unnecessary complexity that could have had problems in the future. Instead, audio will not be added until video starts for sources that have both async audio/video. Audio could have buffered for too long of a time anyway, who knows what devices are going to do. - Fixed a minor conversion warning in audio-io.c

Implement output, improve video/audio subsystems - Fill in the rest of the FFmpeg test output code for testing so it actually properly outputs data. - Improve the main video subsystem to be a bit more optimal and automatically output I420 or NV12 if needed. - Fix audio subsystem insertation and byte calculation. Now it will seamlessly insert new audio data in to the audio stream based upon its timestamp value. (Be extremely cautious when using floating point calculations for important things like this, and always round your values and check your values) - Use 32 byte alignment in case of future optimizations and export a function to get the current alignment. - Make os_sleepto_ns return true if slept, false if the time has already been passed before the call. - Fix sinewave output so that it actually properly calculates a middle C sinewave. - Change the use of row_bytes to linesize (also makes it a bit more consistent with FFmpeg's naming as well)

libobs: Implement new audio subsystem The new audio subsystem fixes two issues: - First Primary issue it fixes is the ability for parent sources to intercept the audio of child sources, and do custom processing on them. The main reason for this was the ability to do custom cross-fading in transitions, but it's also useful for things such as side-chain effects, applying audio effects to entire scenes, applying scene-specific audio filters on sub-sources, and other such possibilities. - The secondary issue that needed fixing was audio buffering. Previously, audio buffering was always a fixed buffer size, so it would always have exactly a certain number of milliseconds of audio buffering (and thus output delay). Instead, it now dynamically increases audio buffering only as necessary, minimizing output delay, and removing the need for users to have to worry about an audio buffering setting. The new design makes it so that audio from the leaves of the scene graph flow to the root nodes, and can be intercepted by parent sources. Each audio source handles its own buffering, and each audio tick a specific number of audio frames are popped from the front of the circular buffer on each audio source. Composite sources (such as scenes) can access the audio for child sources and do custom processing or mixing on that audio. Composite sources use the audio_render callback of sources to do synchronous or deferred audio processing per audio tick. Things like scenes now mix audio from their sub-sources.

This method simply pushes back the audio data while in that window and does not modify sync, and when it detects that its out of the loop window it simply forces a resync of the audio data in the circular buffer. This ensures that minimal audio data is lost in the loop process, and minimizes the likelihood of any sort of sync issues associated with looping.

libobs: Fix an issue that would cause audio stuttering Under certain circumstances, the timing_adjust variable would cause line 1161 to continually trigger over and over again. The "loop detection" code incorrectly made it so that any timestamp that was just simply below the expected value would be seen as a jump. After that, the timing_adjust variable would be set for the frame again, and then the audio would see it as a jump again after that, and those two things would continue endlessly. This would cause stuttering particularly with certain devices (particularly elgato/lgp/hdpvr) where the audio/video data are decoded and sent at varying/different/unpredictable times. To fix this issue, it should not detect values below as jumps, but instead should only do it for values that exceed the MAX_TS_VAR (maximum timestamp variance) value.

libobs: Add frame caching for async video sources The temporary unoptimized code we were using before just completely allocated a new copy of each frame every single time a new async frame was output by the source plugin. This just creates a cache of frames as needed for the current format/width/height to minimize the allocation and deallocation. If new frames come in that are of a different format/width/height, it'll just clear the cache. This is a fairly important optimization.

libobs: Fix async texture data race The obs_source::async_reset_texture variable can cause a data race between threads to occur because it could be set to true in one thread then changed back to false in another thread. This could cause the async texture to not update its size when it's supposed to, which can cause a crash or corruption when copying data from a frame of a differing size. The solution to this is to: - Delete the async_reset_texture variable, and make the set_async_texture_size function change the texture size if the async_width, async_height, or async_format variables differ from the frame's width/height/format. Those variables are then only ever set in the libobs graphics thread. - Make the cache_video function use separate variables from other functions to detect a change in size (due to the fact that the texture size should only be resized in the libobs graphics thread). These variables are async_cache_width, async_cache_height, and async_cache_format, which are only be set in the thread that calls obs_source_output_video. How to replicate the data race: - On OSX, use window capture on a textedit window, then continually resize the textedit window.

libobs: Add deinterlacing API functions Adds deinterlacing API functions. Both standard and 2x variants are supported. Deinterlacing is set via obs_source_set_deinterlace_mode and obs_source_set_deinterlace_field_order. This was implemented in to the core itself because deinterlacing should happen before effect filters are processed, but after async filters are processed. If this were added as a filter, there is the possibility that a different filter is processed before deinterlacing, which could mess with the result. It was also a bit easier to implement this way due to the fact that that deinterlacing may need to have access to the previous async frame. Effects were split in to separate files to reduce load time (especially for yadif shaders which take a significant amount of time to compile).

Almost all resolutions tend to be even. Needs further testing with more devices that support planar YUV 4:2:0 output.

libobs: Add deinterlacing API functions Adds deinterlacing API functions. Both standard and 2x variants are supported. Deinterlacing is set via obs_source_set_deinterlace_mode and obs_source_set_deinterlace_field_order. This was implemented in to the core itself because deinterlacing should happen before effect filters are processed, but after async filters are processed. If this were added as a filter, there is the possibility that a different filter is processed before deinterlacing, which could mess with the result. It was also a bit easier to implement this way due to the fact that that deinterlacing may need to have access to the previous async frame. Effects were split in to separate files to reduce load time (especially for yadif shaders which take a significant amount of time to compile).

libobs: Add frame caching for async video sources The temporary unoptimized code we were using before just completely allocated a new copy of each frame every single time a new async frame was output by the source plugin. This just creates a cache of frames as needed for the current format/width/height to minimize the allocation and deallocation. If new frames come in that are of a different format/width/height, it'll just clear the cache. This is a fairly important optimization.

(API Change) Remove pointers from all typedefs Typedef pointers are unsafe. If you do: typedef struct bla *bla_t; then you cannot use it as a constant, such as: const bla_t, because that constant will be to the pointer itself rather than to the underlying data. I admit this was a fundamental mistake that must be corrected. All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead. This does not break ABI though, which is pretty nice.

libobs: Add planar 4:2:0 async texture support This uses the reverse planar YUV 4:2:0 conversion shader to output a YUV texture without having to convert it via CPU. Again, this will reduce video upload bandwidth usage to 37.5% of the original rate. I suspect this will be particularly useful for when an FFmpeg or libav input plugin for playing videos is made. NOTE: There's an issue with certain texture sizes right now I haven't been able to identify, if the full size of texture data divided by the base texture width is an uneven number, the V chroma plane seems like it can potentially shift, though I only had this happen with 160x90 resolution C920. Almost all resolutions tend to be even. Needs further testing with more devices that support planar YUV 4:2:0 output.

(API Change) Remove pointers from all typedefs Typedef pointers are unsafe. If you do: typedef struct bla *bla_t; then you cannot use it as a constant, such as: const bla_t, because that constant will be to the pointer itself rather than to the underlying data. I admit this was a fundamental mistake that must be corrected. All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead. This does not break ABI though, which is pretty nice.

libobs: Add planar 4:2:0 async texture support This uses the reverse planar YUV 4:2:0 conversion shader to output a YUV texture without having to convert it via CPU. Again, this will reduce video upload bandwidth usage to 37.5% of the original rate. I suspect this will be particularly useful for when an FFmpeg or libav input plugin for playing videos is made. NOTE: There's an issue with certain texture sizes right now I haven't been able to identify, if the full size of texture data divided by the base texture width is an uneven number, the V chroma plane seems like it can potentially shift, though I only had this happen with 160x90 resolution C920. Almost all resolutions tend to be even. Needs further testing with more devices that support planar YUV 4:2:0 output.

(API Change) Remove pointers from all typedefs Typedef pointers are unsafe. If you do: typedef struct bla *bla_t; then you cannot use it as a constant, such as: const bla_t, because that constant will be to the pointer itself rather than to the underlying data. I admit this was a fundamental mistake that must be corrected. All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead. This does not break ABI though, which is pretty nice.

libobs: Add planar 4:2:0 async texture support This uses the reverse planar YUV 4:2:0 conversion shader to output a YUV texture without having to convert it via CPU. Again, this will reduce video upload bandwidth usage to 37.5% of the original rate. I suspect this will be particularly useful for when an FFmpeg or libav input plugin for playing videos is made. NOTE: There's an issue with certain texture sizes right now I haven't been able to identify, if the full size of texture data divided by the base texture width is an uneven number, the V chroma plane seems like it can potentially shift, though I only had this happen with 160x90 resolution C920. Almost all resolutions tend to be even. Needs further testing with more devices that support planar YUV 4:2:0 output.

Fix drawing bug with async video sources Before, async video sources would flicker because they were only being drawn when they were updated. So when updated, they'd draw that frame, then it would stop drawing it until it updated again. This fixes that issue and they should now draw properly. Also, fix a few other minor bugs and issues relating to async video, and make it so that non-async video filters can be properly applied to them. For the purposes of testing, change the 'test-random' source to an async video source that updates every quarter of a second with a new random face. Also fix a bug where non-async video sources wouldn't have filter effects applied properly.

Add planar audio support, improve test output - Add planar audio support. FFmpeg and libav use planar audio for many encoders, so it was somewhat necessary to add support in libobs itself. - Improve/adjust FFmpeg test output plugin. The exports were somewhat messed up (making me rethink how exports should be done). Not yet functional; it handles video properly, but it still does not handle audio properly. - Improve planar video code. The planar video code was not properly accounting for row sizes for each plane. Specifying row sizes for each plane has now been added. This will also make it more compatible with FFmpeg/libav. - Fixed a bug where callbacks wouldn't create properly in audio-io and video-io code. - Implement 'blogva' function to allow for va_list usage with libobs logging.

Fix drawing bug with async video sources Before, async video sources would flicker because they were only being drawn when they were updated. So when updated, they'd draw that frame, then it would stop drawing it until it updated again. This fixes that issue and they should now draw properly. Also, fix a few other minor bugs and issues relating to async video, and make it so that non-async video filters can be properly applied to them. For the purposes of testing, change the 'test-random' source to an async video source that updates every quarter of a second with a new random face. Also fix a bug where non-async video sources wouldn't have filter effects applied properly.

(API Change) Remove pointers from all typedefs Typedef pointers are unsafe. If you do: typedef struct bla *bla_t; then you cannot use it as a constant, such as: const bla_t, because that constant will be to the pointer itself rather than to the underlying data. I admit this was a fundamental mistake that must be corrected. All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead. This does not break ABI though, which is pretty nice.

libobs: Add level/magnitude/peak volume levels This replaces the older code which simply queried the max volume level value for any given audio. I'm still not 100% sure on if this is how I want to approach the problem, particularly, whether this should be done in obs_source or in audio_line, but it can always be moved later if needed. This uses the calculations by the awesome Bill Hamilton that OBS1 used for its volume levels. It calculates the current max (level), magnitude, and current peak. This data then can be used to create awesome volume meter controls later on. NOTE: Will probably need optimization, does one float at a time right now. Also, change some of the naming conventions. I actually need to change a lot of the naming conventions in general so that all words are separated by underscores. Kind of a bad practice there on my part.

libobs: Add level/magnitude/peak volume levels This replaces the older code which simply queried the max volume level value for any given audio. I'm still not 100% sure on if this is how I want to approach the problem, particularly, whether this should be done in obs_source or in audio_line, but it can always be moved later if needed. This uses the calculations by the awesome Bill Hamilton that OBS1 used for its volume levels. It calculates the current max (level), magnitude, and current peak. This data then can be used to create awesome volume meter controls later on. NOTE: Will probably need optimization, does one float at a time right now. Also, change some of the naming conventions. I actually need to change a lot of the naming conventions in general so that all words are separated by underscores. Kind of a bad practice there on my part.

Fix drawing bug with async video sources Before, async video sources would flicker because they were only being drawn when they were updated. So when updated, they'd draw that frame, then it would stop drawing it until it updated again. This fixes that issue and they should now draw properly. Also, fix a few other minor bugs and issues relating to async video, and make it so that non-async video filters can be properly applied to them. For the purposes of testing, change the 'test-random' source to an async video source that updates every quarter of a second with a new random face. Also fix a bug where non-async video sources wouldn't have filter effects applied properly.

(API Change) Remove pointers from all typedefs Typedef pointers are unsafe. If you do: typedef struct bla *bla_t; then you cannot use it as a constant, such as: const bla_t, because that constant will be to the pointer itself rather than to the underlying data. I admit this was a fundamental mistake that must be corrected. All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead. This does not break ABI though, which is pretty nice.

(API Change) Remove pointers from all typedefs Typedef pointers are unsafe. If you do: typedef struct bla *bla_t; then you cannot use it as a constant, such as: const bla_t, because that constant will be to the pointer itself rather than to the underlying data. I admit this was a fundamental mistake that must be corrected. All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead. This does not break ABI though, which is pretty nice.

Fix drawing bug with async video sources Before, async video sources would flicker because they were only being drawn when they were updated. So when updated, they'd draw that frame, then it would stop drawing it until it updated again. This fixes that issue and they should now draw properly. Also, fix a few other minor bugs and issues relating to async video, and make it so that non-async video filters can be properly applied to them. For the purposes of testing, change the 'test-random' source to an async video source that updates every quarter of a second with a new random face. Also fix a bug where non-async video sources wouldn't have filter effects applied properly.

libobs: Update async video texture before effect filters When an async video source is about to be rendered, the async texture should be updated before any effect filtering occurs, rather than right when it's about to render. Fixes a few bugs: - If the async texture hadn't drawn for its first time, and the source has an effect filter, it would never end up rendering the first frame due to the fact that it would fail on obs-source.c:2434 for the first filter, causing it to never actually render the source, and thus never get to a point in which it could call set_async_texture_size to establish the async texture width/height for the first time. - Any time the async texture size changed, it would only update the async texture size at the end of the filter loop, which means that the first frame after a size change would use the old size for the filters rather than update to the new size right away.

Fix drawing bug with async video sources Before, async video sources would flicker because they were only being drawn when they were updated. So when updated, they'd draw that frame, then it would stop drawing it until it updated again. This fixes that issue and they should now draw properly. Also, fix a few other minor bugs and issues relating to async video, and make it so that non-async video filters can be properly applied to them. For the purposes of testing, change the 'test-random' source to an async video source that updates every quarter of a second with a new random face. Also fix a bug where non-async video sources wouldn't have filter effects applied properly.

libobs: Update async video texture before effect filters When an async video source is about to be rendered, the async texture should be updated before any effect filtering occurs, rather than right when it's about to render. Fixes a few bugs: - If the async texture hadn't drawn for its first time, and the source has an effect filter, it would never end up rendering the first frame due to the fact that it would fail on obs-source.c:2434 for the first filter, causing it to never actually render the source, and thus never get to a point in which it could call set_async_texture_size to establish the async texture width/height for the first time. - Any time the async texture size changed, it would only update the async texture size at the end of the filter loop, which means that the first frame after a size change would use the old size for the filters rather than update to the new size right away.

(API Change) Remove pointers from all typedefs Typedef pointers are unsafe. If you do: typedef struct bla *bla_t; then you cannot use it as a constant, such as: const bla_t, because that constant will be to the pointer itself rather than to the underlying data. I admit this was a fundamental mistake that must be corrected. All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead. This does not break ABI though, which is pretty nice.

obs-source.c: Fix a few potential concerns First, if the private data of the source fails to be created, then do not destroy the source. If the source is destroyed, all the user's data associated with that source is lost, which could end up being a potential problem. Instead, let it linger as a 'dead' source until the user chooses to fix the problem (though this should never really happen, the source module functions should be programmed to handle this scenario) Secondly, rename new_frame_ready to ready_async_frame, and fix a potential memory leak with it.

(API Change) Remove pointers from all typedefs Typedef pointers are unsafe. If you do: typedef struct bla *bla_t; then you cannot use it as a constant, such as: const bla_t, because that constant will be to the pointer itself rather than to the underlying data. I admit this was a fundamental mistake that must be corrected. All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead. This does not break ABI though, which is pretty nice.

Fix drawing bug with async video sources Before, async video sources would flicker because they were only being drawn when they were updated. So when updated, they'd draw that frame, then it would stop drawing it until it updated again. This fixes that issue and they should now draw properly. Also, fix a few other minor bugs and issues relating to async video, and make it so that non-async video filters can be properly applied to them. For the purposes of testing, change the 'test-random' source to an async video source that updates every quarter of a second with a new random face. Also fix a bug where non-async video sources wouldn't have filter effects applied properly.

For the purposes of testing, change the 'test-random' source to an async video source that updates every quarter of a second with a new random face. Also fix a bug where non-async video sources wouldn't have filter effects applied properly.

libobs: Remove need for DrawMatrix technique in effects (Note: This commit also modifies obs-filters and text-freetype2) This simplifies writing of effects. DrawMatrix is no longer necessary because there are no sources that require drawing with a color matrix other than async sources, and async sources are automatically processed and don't defer their initial render stage to filters.

obs-source.c: Fix a few potential concerns First, if the private data of the source fails to be created, then do not destroy the source. If the source is destroyed, all the user's data associated with that source is lost, which could end up being a potential problem. Instead, let it linger as a 'dead' source until the user chooses to fix the problem (though this should never really happen, the source module functions should be programmed to handle this scenario) Secondly, rename new_frame_ready to ready_async_frame, and fix a potential memory leak with it.

libobs: Add services API, reduce repeated code Add API for streaming services. The services API simplifies the creation of custom service features and user interface. Custom streaming services later on will be able to do things such as: - Be able to use service-specific APIs via modules, allowing a more direct means of communicating with the service and requesting or setting service-specific information - Get URL/stream key via other means of authentication such as OAuth, or be able to build custom URLs for services that require that sort of thing. - Query information (such as viewer count, chat, follower notifications, and other information) - Set channel information (such as current game, current channel title, activating commercials) Also, I reduce some repeated code that was used for all libobs objects. This includes the name of the object, the private data, settings, as well as the signal and procedure handlers. I also switched to using linked lists for the global object lists, rather than using an array of pointers (you could say it was.. pointless.) ..Anyway, the linked list info is also stored in the shared context data structure.

libobs: Fix audio filters killing video on source When an audio filter is applied to a video source that also has accompanying audio, it would cause the video from the source to stop rendering. The original code this was from was to prevent audio-only sources from rendering video, but I neglected to make sure that this would not apply to filters, and thus when an audio filter is on a source with video, the code would kill the video.

libobs: Update async video texture before effect filters When an async video source is about to be rendered, the async texture should be updated before any effect filtering occurs, rather than right when it's about to render. Fixes a few bugs: - If the async texture hadn't drawn for its first time, and the source has an effect filter, it would never end up rendering the first frame due to the fact that it would fail on obs-source.c:2434 for the first filter, causing it to never actually render the source, and thus never get to a point in which it could call set_async_texture_size to establish the async texture width/height for the first time. - Any time the async texture size changed, it would only update the async texture size at the end of the filter loop, which means that the first frame after a size change would use the old size for the filters rather than update to the new size right away.

It was also a bit easier to implement this way due to the fact that that deinterlacing may need to have access to the previous async frame. Effects were split in to separate files to reduce load time (especially for yadif shaders which take a significant amount of time to compile).

libobs: Implement transition sources Transition sources are implemented by registering a source type as OBS_SOURCE_TYPE_TRANSITION. They're automatically marked as video composite sources, and video_render/audio_render callbacks must be set when registering the source. get_width and get_height callbacks are unused for these types of sources, as transitions automatically handle width/height behind the scenes with the transition settings. In the video_render callback, the helper function obs_transition_video_render is used to assist in automatically processing and rendering the audio. A render callback is passed to the function, which in turn passes to/from textures that are automatically rendered in the back-end. Similarly, in the audio_render callback, the helper function obs_transition_audio_render is used to assist in automatically processing and rendering the audio. Two mix callbacks are used to handle how the source/destination sources are mixed together. To ensure the best possible quality, audio processing is per-sample. Transitions can be set to automatically resize, or they can be set to have a fixed size. Sources within transitions can be made to scale to the transition size (with or without aspect ratio), or to not scale unless they're bigger than the transition. They can have a specific alignment within the transition, or they just default to top-left. These features are implemented for the purpose of extending transitions to also act as "switch" sources later, where you can switch to/from two different sources using the transition animation. Planned (but not yet implemented and lower priority) features: - "Switch" transitions which allow the ability to switch back and forth between two sources with a transitioning animation without discarding the references - Easing options to allow the option to transition with a bezier or custom curve - Manual transitioning to allow the front-end/user to manually control the transition offset

So instead of changing async_width and async_height to 0 when a null frame occurs, change it so that if the source is set to an inactive state, make obs_source_get_width/_get_height return 0 for their dimensions instead.

libobs: Do not clear frame cache if 0,0 dimension Previously I had it set so that it would set the async_width and async_height variables to 0,0 if a null frame occurs, but the problem with this is that it was inadvertently cause the frame cache to clear when it starts receiving textures again because it detects it as a size change. So instead of changing async_width and async_height to 0 when a null frame occurs, change it so that if the source is set to an inactive state, make obs_source_get_width/_get_height return 0 for their dimensions instead.

(API Change) Remove pointers from all typedefs Typedef pointers are unsafe. If you do: typedef struct bla *bla_t; then you cannot use it as a constant, such as: const bla_t, because that constant will be to the pointer itself rather than to the underlying data. I admit this was a fundamental mistake that must be corrected. All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead. This does not break ABI though, which is pretty nice.

(API Change) Remove pointers from all typedefs Typedef pointers are unsafe. If you do: typedef struct bla *bla_t; then you cannot use it as a constant, such as: const bla_t, because that constant will be to the pointer itself rather than to the underlying data. I admit this was a fundamental mistake that must be corrected. All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead. This does not break ABI though, which is pretty nice.

(API Change) Use const params where applicable This Fixes a minor flaw with the API where data had to always be mutable to be usable by the API. Functions that do not modify the fundamental underlying data of a structure should be marked as constant, both for safety and to signify that the parameter is input only and will not be modified by the function using it.

libobs: Add services API, reduce repeated code Add API for streaming services. The services API simplifies the creation of custom service features and user interface. Custom streaming services later on will be able to do things such as: - Be able to use service-specific APIs via modules, allowing a more direct means of communicating with the service and requesting or setting service-specific information - Get URL/stream key via other means of authentication such as OAuth, or be able to build custom URLs for services that require that sort of thing. - Query information (such as viewer count, chat, follower notifications, and other information) - Set channel information (such as current game, current channel title, activating commercials) Also, I reduce some repeated code that was used for all libobs objects. This includes the name of the object, the private data, settings, as well as the signal and procedure handlers. I also switched to using linked lists for the global object lists, rather than using an array of pointers (you could say it was.. pointless.) ..Anyway, the linked list info is also stored in the shared context data structure.

Add planar audio support, improve test output - Add planar audio support. FFmpeg and libav use planar audio for many encoders, so it was somewhat necessary to add support in libobs itself. - Improve/adjust FFmpeg test output plugin. The exports were somewhat messed up (making me rethink how exports should be done). Not yet functional; it handles video properly, but it still does not handle audio properly. - Improve planar video code. The planar video code was not properly accounting for row sizes for each plane. Specifying row sizes for each plane has now been added. This will also make it more compatible with FFmpeg/libav. - Fixed a bug where callbacks wouldn't create properly in audio-io and video-io code. - Implement 'blogva' function to allow for va_list usage with libobs logging.

libobs: Add frame caching for async video sources The temporary unoptimized code we were using before just completely allocated a new copy of each frame every single time a new async frame was output by the source plugin. This just creates a cache of frames as needed for the current format/width/height to minimize the allocation and deallocation. If new frames come in that are of a different format/width/height, it'll just clear the cache. This is a fairly important optimization.

libobs: Fix async texture data race The obs_source::async_reset_texture variable can cause a data race between threads to occur because it could be set to true in one thread then changed back to false in another thread. This could cause the async texture to not update its size when it's supposed to, which can cause a crash or corruption when copying data from a frame of a differing size. The solution to this is to: - Delete the async_reset_texture variable, and make the set_async_texture_size function change the texture size if the async_width, async_height, or async_format variables differ from the frame's width/height/format. Those variables are then only ever set in the libobs graphics thread. - Make the cache_video function use separate variables from other functions to detect a change in size (due to the fact that the texture size should only be resized in the libobs graphics thread). These variables are async_cache_width, async_cache_height, and async_cache_format, which are only be set in the thread that calls obs_source_output_video. How to replicate the data race: - On OSX, use window capture on a textedit window, then continually resize the textedit window.

libobs: Use reference counting with source frames When a frame is processed by a filter, it comes directly from the source's video frame cache. However, if a filter is using or processing those frames for whatever reason, there would be no guarantee that the frames would persist during processing, and frames could eventually be deallocated unexpected, for example when the resolution or format changes. So the solution is to implement simple reference counting for the frames so that the frames will exist until they have been released by any source or filter that's using them.

libobs: Add deinterlacing API functions Adds deinterlacing API functions. Both standard and 2x variants are supported. Deinterlacing is set via obs_source_set_deinterlace_mode and obs_source_set_deinterlace_field_order. This was implemented in to the core itself because deinterlacing should happen before effect filters are processed, but after async filters are processed. If this were added as a filter, there is the possibility that a different filter is processed before deinterlacing, which could mess with the result. It was also a bit easier to implement this way due to the fact that that deinterlacing may need to have access to the previous async frame. Effects were split in to separate files to reduce load time (especially for yadif shaders which take a significant amount of time to compile).

libobs: Reset frame cache if it gets too big When buffering is enabled for an async video source, sometimes minor drift in timestamps or unexpected delays to frames can cause frames to slowly buffer more and more in memory, in some cases eventually causing the system to run out of memory. The circumstances in which this can happen seems to depend on both the computer and the devices in use. So far, the only known circumstances in which this happens are with heavily buffered devices, such as hauppauge, where decoding can sometimes take too long and cause continual frame playback delay, and thus continual buffering until memory runs out. I've never been able to replicate it on any of my machines however, even after hours of testing. This patch is a precautionary measure that puts a hard limit on the number of async frames that can be currently queued to prevent any case where memory might continually build for whatever reason. If it goes over the limit, it clears the cache to reset the buffering. I had a user with this problem test this patch with success and positive feedback, and the intervals between buffering resets were long to where it wasn't even noticeable while streaming/recording. Ideally when decoding frames (such as from those devices), frame dropping should be used to ensure playback doesn't incur extra delay, although this sort of hard limit on the frame cache should still be implemented regardless just as a safety precaution. For DirectShow encoded devices I should just switch to faruton's libff for decoding and enable the frame dropping options. It would probably explain why no one's ever reported it for the media source, and pretty much only from DirectShow device usage.

If you do: typedef struct bla *bla_t; then you cannot use it as a constant, such as: const bla_t, because that constant will be to the pointer itself rather than to the underlying data. I admit this was a fundamental mistake that must be corrected. All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead.

(API Change) Remove pointers from all typedefs Typedef pointers are unsafe. If you do: typedef struct bla *bla_t; then you cannot use it as a constant, such as: const bla_t, because that constant will be to the pointer itself rather than to the underlying data. I admit this was a fundamental mistake that must be corrected. All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead. This does not break ABI though, which is pretty nice.

If the source is destroyed, all the user's data associated with that source is lost, which could end up being a potential problem. Instead, let it linger as a 'dead' source until the user chooses to fix the problem (though this should never really happen, the source module functions should be programmed to handle this scenario) Secondly, rename new_frame_ready to ready_async_frame, and fix a potential memory leak with it.

libobs: Add services API, reduce repeated code Add API for streaming services. The services API simplifies the creation of custom service features and user interface. Custom streaming services later on will be able to do things such as: - Be able to use service-specific APIs via modules, allowing a more direct means of communicating with the service and requesting or setting service-specific information - Get URL/stream key via other means of authentication such as OAuth, or be able to build custom URLs for services that require that sort of thing. - Query information (such as viewer count, chat, follower notifications, and other information) - Set channel information (such as current game, current channel title, activating commercials) Also, I reduce some repeated code that was used for all libobs objects. This includes the name of the object, the private data, settings, as well as the signal and procedure handlers. I also switched to using linked lists for the global object lists, rather than using an array of pointers (you could say it was.. pointless.) ..Anyway, the linked list info is also stored in the shared context data structure.

Simplify media i/o interfaces Completely revamped the entire media i/o data and handlers. The original idea was to have a system that would have connecting media inputs and outputs, but at a certain point I realized that this was an unnecessary complexity for what we wanted to do. (Also, it reminded me of directshow filters, and I HATE directshow with a passion, and wouldn't wish it upon my greatest enemy) Now, audio/video outputs are connected to directly, with better callback handlers, and will eventually have the ability to automatically handle conversions such as 4:4:4 to 4:2:0 when connecting to an input that uses them. Doing this will allow the video/audio i/o handlers to also prevent duplicate conversion, as well as make it easier/simple to use. My true goal for this is to make output and encoder plugins as simple to create as possible. I want to be able to be able to create an output plugin with almost no real hassle of having to worry about image conversions, media inputs/outputs, etc. A plugin developer shouldn't have to handle that sort of stuff when he/she doesn't really need to. Plugins will be able to simply create a callback via obs_video() and/or obs_audio(), and they will automatically receive the audio/video data in the formats requested via a simple callback, without needing to do almost anything else at all.

Revamp API and start using doxygen The API used to be designed in such a way to where it would expect exports for each individual source/output/encoder/etc. You would export functions for each and it would automatically load those functions based on a specific naming scheme from the module. The idea behind this was that I wanted to limit the usage of structures in the API so only functions could be used. It was an interesting idea in theory, but this idea turned out to be flawed in a number of ways: 1.) Requiring exports to create sources/outputs/encoders/etc meant that you could not create them by any other means, which meant that things like faruton's .net plugin would become difficult. 2.) Export function declarations could not be checked, therefore if you created a function with the wrong parameters and parameter types, the compiler wouldn't know how to check for that. 3.) Required overly complex load functions in libobs just to handle it. It makes much more sense to just have a load function that you call manually. Complexity is the bane of all good programs. 4.) It required that you have functions of specific names, which looked and felt somewhat unsightly. So, to fix these issues, I replaced it with a more commonly used API scheme, seen commonly in places like kernels and typical C libraries with abstraction. You simply create a structure that contains the callback definitions, and you pass it to a function to register that definition (such as obs_register_source), which you call in the obs_module_load of the module. It will also automatically check the structure size and ensure that it only loads the required values if the structure happened to add new values in an API change. The "main" source file for each module must include obs-module.h, and must use OBS_DECLARE_MODULE() within that source file. Also, started writing some doxygen documentation in to the main library headers. Will add more detailed documentation as I go.

Add planar audio support, improve test output - Add planar audio support. FFmpeg and libav use planar audio for many encoders, so it was somewhat necessary to add support in libobs itself. - Improve/adjust FFmpeg test output plugin. The exports were somewhat messed up (making me rethink how exports should be done). Not yet functional; it handles video properly, but it still does not handle audio properly. - Improve planar video code. The planar video code was not properly accounting for row sizes for each plane. Specifying row sizes for each plane has now been added. This will also make it more compatible with FFmpeg/libav. - Fixed a bug where callbacks wouldn't create properly in audio-io and video-io code. - Implement 'blogva' function to allow for va_list usage with libobs logging.

libobs: Add frame caching for async video sources The temporary unoptimized code we were using before just completely allocated a new copy of each frame every single time a new async frame was output by the source plugin. This just creates a cache of frames as needed for the current format/width/height to minimize the allocation and deallocation. If new frames come in that are of a different format/width/height, it'll just clear the cache. This is a fairly important optimization.

libobs: Add deinterlacing API functions Adds deinterlacing API functions. Both standard and 2x variants are supported. Deinterlacing is set via obs_source_set_deinterlace_mode and obs_source_set_deinterlace_field_order. This was implemented in to the core itself because deinterlacing should happen before effect filters are processed, but after async filters are processed. If this were added as a filter, there is the possibility that a different filter is processed before deinterlacing, which could mess with the result. It was also a bit easier to implement this way due to the fact that that deinterlacing may need to have access to the previous async frame. Effects were split in to separate files to reduce load time (especially for yadif shaders which take a significant amount of time to compile).

(API Change) Remove pointers from all typedefs Typedef pointers are unsafe. If you do: typedef struct bla *bla_t; then you cannot use it as a constant, such as: const bla_t, because that constant will be to the pointer itself rather than to the underlying data. I admit this was a fundamental mistake that must be corrected. All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead. This does not break ABI though, which is pretty nice.

Add preliminary handling of timestamp invalidation - Add preliminary (yet to be tested) handling of timestamp invalidation issues that can happen with specific devices, where timestamps can reset or go backward/forward in time with no rhyme or reason. Spent the entire day just trying to figure out the best way to handle this. If both audio and video are present, it will increment a reference counter if video timestamps invalidate, and decrement the reference counter when the audio timestamps invalidate. When the reference counter is not 0, it will not send audio as the audio will have invalid timing. What this does is it ensures audio data will never go out of bounds in relation to the video, and waits for both audio and video timestamps to "jump" together before resuming audio. - Moved async video frame timing adjustment code into obs_source_getframe instead so it's automatically handled whenever called. - Removed the 'audio wait buffer' as it was an unnecessary complexity that could have had problems in the future. Instead, audio will not be added until video starts for sources that have both async audio/video.

libobs: Increase async jitter compensation Due to the fact that async timestamps themselves can be susceptible to minor jitter from certain types of inputs, increase the allowable jitter compensation value to ensure that the rendered frame timing from async video sources is always as close as possible to the compositor. When the framerate of the source is the same as the framerate as the compositor, this (combined with the fact that clamped video timing now being used with async video frames) helps ensure that buffered async video sources will sync up their rendering to the compositor as accurately as possible despite jitter from the source's timestamps. If there is no jitter in the source's timestamps then it'll always sync up perfectly with the compositor, thanks to clamped video timing.

What this does is it ensures audio data will never go out of bounds in relation to the video, and waits for both audio and video timestamps to "jump" together before resuming audio. - Moved async video frame timing adjustment code into obs_source_getframe instead so it's automatically handled whenever called. - Removed the 'audio wait buffer' as it was an unnecessary complexity that could have had problems in the future. Instead, audio will not be added until video starts for sources that have both async audio/video. Audio could have buffered for too long of a time anyway, who knows what devices are going to do. - Fixed a minor conversion warning in audio-io.c

/* more timestamp checking and compensating */
Use MAX_TS_VAR for timestamp jump detection This combines the 'direct' timestamp variance threshold with the maximum timestamp jump threshold (or rather just removes the max timestamp jump threshold and uses the timestamp variance threshold for both timestamp jumps and detecting timestamps). The reason why this was done was because a timestamp jump could occur at a higher threshold than the threshold used for detecting OS timestamps within a certain threshold. If timestamps got between those two thresholds it kind of became a weird situation where timestamps could be sort of 'stuck' back or forward in time more than intended. Better to be consistent and use the same threshold for both values.

obs-source.c: Fix a few potential concerns First, if the private data of the source fails to be created, then do not destroy the source. If the source is destroyed, all the user's data associated with that source is lost, which could end up being a potential problem. Instead, let it linger as a 'dead' source until the user chooses to fix the problem (though this should never really happen, the source module functions should be programmed to handle this scenario) Secondly, rename new_frame_ready to ready_async_frame, and fix a potential memory leak with it.

(API Change) Remove pointers from all typedefs Typedef pointers are unsafe. If you do: typedef struct bla *bla_t; then you cannot use it as a constant, such as: const bla_t, because that constant will be to the pointer itself rather than to the underlying data. I admit this was a fundamental mistake that must be corrected. All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead. This does not break ABI though, which is pretty nice.

(API Change) Fix filter rendering design flaw obs_source_process_filter tried to do everything in a single function, but the problem is that effect parameters would not properly be accounted for due to the way it internally draws, therefore it was necessary to split the functions in to two, you first call obs_source_process_filter_begin, then you set your effect parameters, then you finally call obs_source_process_filter_end. This ensures that when the filter is drawn, that the effect parameters are set.

(API Change) Remove pointers from all typedefs Typedef pointers are unsafe. If you do: typedef struct bla *bla_t; then you cannot use it as a constant, such as: const bla_t, because that constant will be to the pointer itself rather than to the underlying data. I admit this was a fundamental mistake that must be corrected. All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead. This does not break ABI though, which is pretty nice.

(API Change) Fix filter rendering design flaw obs_source_process_filter tried to do everything in a single function, but the problem is that effect parameters would not properly be accounted for due to the way it internally draws, therefore it was necessary to split the functions in to two, you first call obs_source_process_filter_begin, then you set your effect parameters, then you finally call obs_source_process_filter_end. This ensures that when the filter is drawn, that the effect parameters are set.

libobs: Use 'can_bypass' func for filter bypassing There are a few more conditions which need to be checked to ensure whether we can actually bypass or not; in this particular case we are using the YUV texture shaders, plus the image can also be flipped, so we can't really use the bypass optimization in those situations.

Revamp API and start using doxygen The API used to be designed in such a way to where it would expect exports for each individual source/output/encoder/etc. You would export functions for each and it would automatically load those functions based on a specific naming scheme from the module. The idea behind this was that I wanted to limit the usage of structures in the API so only functions could be used. It was an interesting idea in theory, but this idea turned out to be flawed in a number of ways: 1.) Requiring exports to create sources/outputs/encoders/etc meant that you could not create them by any other means, which meant that things like faruton's .net plugin would become difficult. 2.) Export function declarations could not be checked, therefore if you created a function with the wrong parameters and parameter types, the compiler wouldn't know how to check for that. 3.) Required overly complex load functions in libobs just to handle it. It makes much more sense to just have a load function that you call manually. Complexity is the bane of all good programs. 4.) It required that you have functions of specific names, which looked and felt somewhat unsightly. So, to fix these issues, I replaced it with a more commonly used API scheme, seen commonly in places like kernels and typical C libraries with abstraction. You simply create a structure that contains the callback definitions, and you pass it to a function to register that definition (such as obs_register_source), which you call in the obs_module_load of the module. It will also automatically check the structure size and ensure that it only loads the required values if the structure happened to add new values in an API change. The "main" source file for each module must include obs-module.h, and must use OBS_DECLARE_MODULE() within that source file. Also, started writing some doxygen documentation in to the main library headers. Will add more detailed documentation as I go.

Fixes a few bugs: - If the async texture hadn't drawn for its first time, and the source has an effect filter, it would never end up rendering the first frame due to the fact that it would fail on obs-source.c:2434 for the first filter, causing it to never actually render the source, and thus never get to a point in which it could call set_async_texture_size to establish the async texture width/height for the first time. - Any time the async texture size changed, it would only update the async texture size at the end of the filter loop, which means that the first frame after a size change would use the old size for the filters rather than update to the new size right away.

Deinterlacing is set via obs_source_set_deinterlace_mode and obs_source_set_deinterlace_field_order. This was implemented in to the core itself because deinterlacing should happen before effect filters are processed, but after async filters are processed. If this were added as a filter, there is the possibility that a different filter is processed before deinterlacing, which could mess with the result. It was also a bit easier to implement this way due to the fact that that deinterlacing may need to have access to the previous async frame. Effects were split in to separate files to reduce load time (especially for yadif shaders which take a significant amount of time to compile).

All typedefs that were pointer types will now have their pointers removed from the type itself, and the pointers will be used when they are actually used as variables/parameters/returns instead. This does not break ABI though, which is pretty nice.

void obs_source_set_volume(obs_source_t *source, float volume)
Implement volumes for sources - Added a volume variable to the obs_source structure and implemented functions for manipulating source volume. - Added a volume variable to the audio_data structure so that the volume will be applied when mixing.

libobs: Implement new audio subsystem The new audio subsystem fixes two issues: - First Primary issue it fixes is the ability for parent sources to intercept the audio of child sources, and do custom processing on them. The main reason for this was the ability to do custom cross-fading in transitions, but it's also useful for things such as side-chain effects, applying audio effects to entire scenes, applying scene-specific audio filters on sub-sources, and other such possibilities. - The secondary issue that needed fixing was audio buffering. Previously, audio buffering was always a fixed buffer size, so it would always have exactly a certain number of milliseconds of audio buffering (and thus output delay). Instead, it now dynamically increases audio buffering only as necessary, minimizing output delay, and removing the need for users to have to worry about an audio buffering setting. The new design makes it so that audio from the leaves of the scene graph flow to the root nodes, and can be intercepted by parent sources. Each audio source handles its own buffering, and each audio tick a specific number of audio frames are popped from the front of the circular buffer on each audio source. Composite sources (such as scenes) can access the audio for child sources and do custom processing or mixing on that audio. Composite sources use the audio_render callback of sources to do synchronous or deferred audio processing per audio tick. Things like scenes now mix audio from their sub-sources.

libobs: Add services API, reduce repeated code Add API for streaming services. The services API simplifies the creation of custom service features and user interface. Custom streaming services later on will be able to do things such as: - Be able to use service-specific APIs via modules, allowing a more direct means of communicating with the service and requesting or setting service-specific information - Get URL/stream key via other means of authentication such as OAuth, or be able to build custom URLs for services that require that sort of thing. - Query information (such as viewer count, chat, follower notifications, and other information) - Set channel information (such as current game, current channel title, activating commercials) Also, I reduce some repeated code that was used for all libobs objects. This includes the name of the object, the private data, settings, as well as the signal and procedure handlers. I also switched to using linked lists for the global object lists, rather than using an array of pointers (you could say it was.. pointless.) ..Anyway, the linked list info is also stored in the shared context data structure.

Simplify and extend callback/signalling system - Signals and dynamic callbacks now require declarations to be made before being used. What this does is allows us to get information about the functions dynamically which can be relayed to the user and plugins for future extended usage (this should have big implications later for scripting in particular, hopefully). - Reduced the number of types calldata uses from "everything I could think of" to simply integer, float, bool, pointer/object, string. Integer data is now stored as long long. Floats are now stored as doubles (check em). - Use a more consistent naming scheme for lexer error/warning macros. - Fixed a rather nasty bug where switching to an existing scene would cause it to increment sourceSceneRefs, which would mean that it would never end up never properly removing the source when the user clicks removed (stayed in limbo, obs_source_remove never got called)

libobs: Implement transition sources Transition sources are implemented by registering a source type as OBS_SOURCE_TYPE_TRANSITION. They're automatically marked as video composite sources, and video_render/audio_render callbacks must be set when registering the source. get_width and get_height callbacks are unused for these types of sources, as transitions automatically handle width/height behind the scenes with the transition settings. In the video_render callback, the helper function obs_transition_video_render is used to assist in automatically processing and rendering the audio. A render callback is passed to the function, which in turn passes to/from textures that are automatically rendered in the back-end. Similarly, in the audio_render callback, the helper function obs_transition_audio_render is used to assist in automatically processing and rendering the audio. Two mix callbacks are used to handle how the source/destination sources are mixed together. To ensure the best possible quality, audio processing is per-sample. Transitions can be set to automatically resize, or they can be set to have a fixed size. Sources within transitions can be made to scale to the transition size (with or without aspect ratio), or to not scale unless they're bigger than the transition. They can have a specific alignment within the transition, or they just default to top-left. These features are implemented for the purpose of extending transitions to also act as "switch" sources later, where you can switch to/from two different sources using the transition animation. Planned (but not yet implemented and lower priority) features: - "Switch" transitions which allow the ability to switch back and forth between two sources with a transitioning animation without discarding the references - Easing options to allow the option to transition with a bezier or custom curve - Manual transitioning to allow the front-end/user to manually control the transition offset

Implement source activation/deactivation Now sources will be properly activated and deactivated when they are in use or not in use. Had to figure out a way to handle child sources, and children of children, just ended up implementing simple functions that parents use to signal adding/removal to help with hierarchial activation and deactivation of child sources. To prevent the source activate/deactivate callbacks from being called more than once, added an activation reference counter. The first increment will call the activate callback, and the last decrement will call the deactivate callback. Added "source-activate" and "source-deactivate" signals to the main obs signal handler, and "activate" and "deactivate" to individual source signal handlers. Also, fixed the main window so it properly selects a source when the current active scene has been changed.

Separate source activation for main/aux views Split off activate to activate and show callbacks, and split off deactivate to deactivate and hide callbacks. Sources didn't previously have a means to know whether it was actually being displayed in the main view or just happened to be visible somewhere. Now, for things like transition sources, they have a means of knowing when they have actually been "activated" so they can initiate their sequence. A source is now only considered "active" when it's being displayed by the main view. When a source is shown in the main view, the activate callback/signal is triggered. When it's no longer being displayed by the main view, deactivate callback/signal is triggered. When a source is just generally visible to see by any view, the show callback/signal is triggered. If it's no longer visible by any views, then the hide callback/signal is triggered. Presentation volume will now only be active when a source is active in the main view rather than also in auxilary views. Also fix a potential bug where parents wouldn't properly increment or decrement all the activation references of a child source when a child was added or removed.

Implement volume handling - Remove obs_source::type because it became redundant now that the type is always stored in the obs_source::info variable. - Apply presentation volumes of 1.0 and 0.0 to sources when they activate/deactivate, respectively. It also applies that presentation volume to all sub-sources, with exception of transition sources. Transition sources must apply presentation volume manually to their sub-sources with the new transition functions below. - Add a "transition_volume" variable to obs_source structure, and add three functions for handling volume for transitions: * obs_transition_begin_frame * obs_source_set_transition_vol * obs_transition_end_frame Because the to/from targets of a transition source might both contain some of the same sources, handling the transitioning of volumes for that specific situation becomes an issue. So for transitions, instead of modifying the presentation volumes directly for both sets of sources, we do this: - First, call obs_transition_begin_frame at the beginning of each transition frame, which will reset transition volumes for all sub-sources to 0. Presentation volumes remain unchanged. - Call obs_source_set_transition_vol on each sub-source, which will then add the volume to the transition volume for each source in that source's tree. Presentation volumes still remain unchanged. - Then you call obs_trandition_end_frame when complete, which will then finally set the presentation volumes to the transition volumes. For example, let's say that there's one source that's within both the "transitioning from" sources and "transition to" sources. It would add both the fade in and fade out volumes to that source, and then when the frame is complete, it would set the presentation volume to the sum of those two values, rather than set the presentation volume for that same source twice which would cause weird volume jittering and also set the wrong values.

The optional 'load' callback will be called only after having loaded setttings specifically from file/imported data, and the 'save' function will be called only specifically when data actually needs to be saved.

The optional 'load' callback will be called only after having loaded setttings specifically from file/imported data, and the 'save' function will be called only specifically when data actually needs to be saved. I also had to adjust the obs_scene code so that it's a regular input source type now, and I also modified it so that it doesn't have some strange custom creation code anymore. The obs_scene_create function is now simply just a wrapper for obs_source_create. You could even create a scene with obs_source_create manually as well.

Add helper functions for drawing sources If you look at the previous commits, you'll see I had added obs_source_draw before. For custom drawn sources in particular, each time obs_source_draw was called, it would restart the effect and its passes for each draw call, which was not optimal. It should really use the effect functions for that. I'll have to add a function to simplify effect usage. I also realized that including the color matrix parameters in obs_source_draw made the function kind of messy to use; instead, separating the color matrix stuff out to obs_source_draw_set_color_matrix feels a lot more clean. On top of that, having the ability to set the position would be nice to have as well, rather than having to mess with the matrix stuff each time, so I also added that for the sake of convenience. obs_source_draw will draw a texture sprite, optionally of a specific size and/or at a specific position, as well as optionally inverted. The texture used will be set to the 'image' parameter of whatever effect is currently active. obs_source_draw_set_color_matrix will set the color matrix value if the drawing requires color matrices. It will set the 'color_matrix', 'color_range_min', and 'color_range_max' parameters of whatever effect is currently active. Overall, these feel much more clean to use than the previous iteration.

(API Change) Add support for multiple audio mixers API changed: -------------------------- void obs_output_set_audio_encoder( obs_output_t *output, obs_encoder_t *encoder); obs_encoder_t *obs_output_get_audio_encoder( const obs_output_t *output); obs_encoder_t *obs_audio_encoder_create( const char *id, const char *name, obs_data_t *settings); Changed to: -------------------------- /* 'idx' specifies the track index of the output */ void obs_output_set_audio_encoder( obs_output_t *output, obs_encoder_t *encoder, size_t idx); /* 'idx' specifies the track index of the output */ obs_encoder_t *obs_output_get_audio_encoder( const obs_output_t *output, size_t idx); /* 'mixer_idx' specifies the mixer index to capture audio from */ obs_encoder_t *obs_audio_encoder_create( const char *id, const char *name, obs_data_t *settings, size_t mixer_idx); Overview -------------------------- This feature allows multiple audio mixers to be used at a time. This capability was able to be added with surprisingly very little extra overhead. Audio will not be mixed unless it's assigned to a specific mixer, and mixers will not mix unless they have an active mix connection. Mostly this will be useful for being able to separate out specific audio for recording versus streaming, but will also be useful for certain streaming services that support multiple audio streams via RTMP. I didn't want to use a variable amount of mixers due to the desire to reduce heap allocations, so currently I set the limit to 4 simultaneous mixers; this number can be increased later if needed, but honestly I feel like it's just the right number to use. Sources: Sources can now specify which audio mixers their audio is mixed to; this can be a single mixer or multiple mixers at a time. The obs_source_set_audio_mixers function sets the audio mixer which an audio source applies to. For example, 0xF would mean that the source applies to all four mixers. Audio Encoders: Audio encoders now must specify which specific audio mixer they use when they encode audio data. Outputs: Outputs that use encoders can now support multiple audio tracks at once if they have the OBS_OUTPUT_MULTI_TRACK capability flag set. This is mostly only useful for certain types of RTMP transmissions, though may be useful for file formats that support multiple audio tracks as well later on.

The obs_source_set_audio_mixers function sets the audio mixer which an audio source applies to. For example, 0xF would mean that the source applies to all four mixers. Audio Encoders: Audio encoders now must specify which specific audio mixer they use when they encode audio data. Outputs: Outputs that use encoders can now support multiple audio tracks at once if they have the OBS_OUTPUT_MULTI_TRACK capability flag set. This is mostly only useful for certain types of RTMP transmissions, though may be useful for file formats that support multiple audio tracks as well later on.

libobs: Store source audio mixers in obs_source (skip) (Note: This commit breaks libobs compilation. Skip if bisecting) The mixers that a source was assigned to were originally stored in the audio line. This will store it in the sources themselves instead.

(API Change) Add support for multiple audio mixers API changed: -------------------------- void obs_output_set_audio_encoder( obs_output_t *output, obs_encoder_t *encoder); obs_encoder_t *obs_output_get_audio_encoder( const obs_output_t *output); obs_encoder_t *obs_audio_encoder_create( const char *id, const char *name, obs_data_t *settings); Changed to: -------------------------- /* 'idx' specifies the track index of the output */ void obs_output_set_audio_encoder( obs_output_t *output, obs_encoder_t *encoder, size_t idx); /* 'idx' specifies the track index of the output */ obs_encoder_t *obs_output_get_audio_encoder( const obs_output_t *output, size_t idx); /* 'mixer_idx' specifies the mixer index to capture audio from */ obs_encoder_t *obs_audio_encoder_create( const char *id, const char *name, obs_data_t *settings, size_t mixer_idx); Overview -------------------------- This feature allows multiple audio mixers to be used at a time. This capability was able to be added with surprisingly very little extra overhead. Audio will not be mixed unless it's assigned to a specific mixer, and mixers will not mix unless they have an active mix connection. Mostly this will be useful for being able to separate out specific audio for recording versus streaming, but will also be useful for certain streaming services that support multiple audio streams via RTMP. I didn't want to use a variable amount of mixers due to the desire to reduce heap allocations, so currently I set the limit to 4 simultaneous mixers; this number can be increased later if needed, but honestly I feel like it's just the right number to use. Sources: Sources can now specify which audio mixers their audio is mixed to; this can be a single mixer or multiple mixers at a time.

Add helper functions for drawing sources If you look at the previous commits, you'll see I had added obs_source_draw before. For custom drawn sources in particular, each time obs_source_draw was called, it would restart the effect and its passes for each draw call, which was not optimal. It should really use the effect functions for that. I'll have to add a function to simplify effect usage. I also realized that including the color matrix parameters in obs_source_draw made the function kind of messy to use; instead, separating the color matrix stuff out to obs_source_draw_set_color_matrix feels a lot more clean. On top of that, having the ability to set the position would be nice to have as well, rather than having to mess with the matrix stuff each time, so I also added that for the sake of convenience. obs_source_draw will draw a texture sprite, optionally of a specific size and/or at a specific position, as well as optionally inverted. The texture used will be set to the 'image' parameter of whatever effect is currently active. obs_source_draw_set_color_matrix will set the color matrix value if the drawing requires color matrices. It will set the 'color_matrix', 'color_range_min', and 'color_range_max' parameters of whatever effect is currently active. Overall, these feel much more clean to use than the previous iteration.

libobs: Refactor source volume transition design This changes the way source volume handles transitioning between being active and inactive states. The previous way that transitioning handled volume was that it set the presentation volume of the source and all of its sub-sources to 0.0 if the source was inactive, and 1.0 if active. Transition sources would then also set the presentation volume for sub-sources to whatever their transitioning volume was. However, the problem with this is that the design didn't take in to account if the source or its sub-sources were active anywhere else, so because of that it would break if that ever happened, and I didn't realize that when I was designing it. So instead, this completely overhauls the design of handling transitioning volume. Each frame, it'll go through all sources and check whether they're active or inactive and set the base volume accordingly. If transitions are currently active, it will actually walk the active source tree and check whether the source is in a transitioning state somewhere. - If the source is a sub-source of a transition, and it's not active outside of the transition, then the transition will control the volume of the source. - If the source is a sub-source of a transition, but it's also active outside of the transition, it'll defer to whichever is louder. This also adds a new callback to the obs_source_info structure for transition sources, get_transition_volume, which is called to get the transitioning volume of a sub-source.

libobs: Implement new audio subsystem The new audio subsystem fixes two issues: - First Primary issue it fixes is the ability for parent sources to intercept the audio of child sources, and do custom processing on them. The main reason for this was the ability to do custom cross-fading in transitions, but it's also useful for things such as side-chain effects, applying audio effects to entire scenes, applying scene-specific audio filters on sub-sources, and other such possibilities. - The secondary issue that needed fixing was audio buffering. Previously, audio buffering was always a fixed buffer size, so it would always have exactly a certain number of milliseconds of audio buffering (and thus output delay). Instead, it now dynamically increases audio buffering only as necessary, minimizing output delay, and removing the need for users to have to worry about an audio buffering setting. The new design makes it so that audio from the leaves of the scene graph flow to the root nodes, and can be intercepted by parent sources. Each audio source handles its own buffering, and each audio tick a specific number of audio frames are popped from the front of the circular buffer on each audio source. Composite sources (such as scenes) can access the audio for child sources and do custom processing or mixing on that audio. Composite sources use the audio_render callback of sources to do synchronous or deferred audio processing per audio tick. Things like scenes now mix audio from their sub-sources.
