Add all missing obs_frontend_*() functions, plus organize the
`obs_frontend_event` enum. It wasn't ordered the same as the header
file, so we might as well take the opportunity to make it clearer.
- Changes the note under obs_sceneitem_get_id(). Getting the id of a
sceneitem is not dangerous and does not cause errors. Only
obs_sceneitem_set_id() can cause errors.
- Changes wording on `obs_group_or_scene_from_source()`
Currently, ifdefs are used to determine if monitoring is supported.
This is difficult to maintain and restricts plugins from knowing if
monitoring is supported by OBS. This adds a runtime function to fix
that issue.
The gs_texture_create_from_dmabuf function is a wrapper for
eglCreateImageKHR, which can set a different modifier for each plane.
The documentation should advice against that, since this should be
rejected by the driver.
While DMA-BUFs started to have one modifier per plane, this decision was
rolled back to having one modifier for the whole buffer / all planes.
While some apis like EGL were designed with a modifier per plane,
drivers are expected to reject any request using different modifiers per
plane.
In order to do linear-correct filtering cheaply when scale filtering is
disabled, we need to know whether or not texture coordinates will always
sample from texel centers. This can be computed at the scene item level
relatively easily, and passed along to sources when rendering. Scene
items will use obs_source_set_texcoords_centered to set hint status, and
sources will use obs_source_get_texcoords_centered to retrieve it.
Add OBS_SOURCE_SRGB to indicate sources that support SRGB rendering. We
can use this flag to know which sources do not know how to handle SRGB,
and disable accordingly inside obs_source_main_render().
We can also use this flag to clean up the filter interface and remove
the SRGB-specific functions. We also need to disable direct rendering if
the filter source wants to render SRGB, but the parent source does not
support it.
Scenes and groups are marked as having SRGB support, and those are
internal sources that we control.
Allows the ability to reset (erase) a source's existing settings and
replace them with new settings. This is useful for things such as
reverting to older settings.
Implements obs_data_get_defaults and updates the documentation. This is
supposed to allow someone to access all the defaults of an object.
Should help in cases where the full data is needed, and not just the
currently set.
This function determines if something is an OBS plugin before attempting
to load it. On Windows, many plugins ship their dependent DLLs alongside
the plugin DLL, so OBS would load things like libcef.dll on startup only
to immediately free it. For other platforms, this is less of a concern
so this function is a no-op for now.
This improves startup time and reduces risk from dependent DLLs
potentially running code with unwanted side effects in DllMain.
This adds functions to the frontend api to start/stop the virtual
camera, to check if it is active and adds function to get the output
reference. It also adds api events for when the virtual camera is
started or stopped.
* obs-frontend-api: add the event of saving replay buffer
Add OBS_FRONTEND_EVENT_REPLAY_BUFFER_SAVED as given by RFC 33
* UI: Emit the replay buffer saved event to the api
Send the OBS_FRONTEND_EVENT_REPLAY_BUFFER_SAVED to api (as in rfc33)
* docs/sphinx: Add replay buffer saved event
Documentation provided for OBS_FRONTEND_EVENT_REPLAY_BUFFER_SAVED (RFC33)
Returns whether rescaling is enabled for an encoder. This will be used
with texture-based encoders to determine whether to fall back to
RAM-based encoding instead.
Adds API:
obs_scene_add_group2
obs_scene_insert_group2
obs_sceneitem_group_ungroup2
These functions should be used by plugins if they need to use these
functions and need to send a refresh signal. If a major API rework ever
happens the old functions should be removed. The old functions should
eventually be deprecated.
The reason why specifying a 'signal' parameter is useful is because it's
a bit more seamless for the user interface to be able to have custom
handling of these specific cases. It looks better and doesn't require
completely erasing/recreating the entire list, which is visually
unappealing.
This allows the ability to do things such as change defaults or
properties of sources without necessarily breaking older user
configurations that had older defaults or properties.
Adds support for pausing recordings. When settings are eligible for
recordings, a pause button will appear next to the recording button. If
the settings are not eligible, it will warn the user in the output
settings that they cannot pause recordings if those settings are used.
This implements pausing of outputs. To accomplish this, raw audio/video
data is halted to the encoders or raw output. Pausing is as precisely
timed as possible according to the timing of the obs_output_pause call,
and audio data will be spliced down to the exact audio sample in
accordance to that timing at the start/end marks.
Outputs that support this (outputs used for recording) can set the
OBS_OUTPUT_CAN_PAUSE capability flag.
Similar to item_visible, this event fires whenever a scene item is
locked or unlocked. This allows the UI and libobs to remain in sync
regarding scene elements' statuses.
(This commit also modifies the UI, obs-ffmpeg, and obs-output modules)
Fixes a long-time regression where the program would lock up if an
encode call fails. Shuts down all outputs associated with the failing
encoder and displays an error message to the user.
Ideally, it would be best if a more detailed error could be displayed to
the user about the nature of the error, though the primary problem is
the encoder errors are typically not something the user would be able to
understand. The current message is a bit of a generic error message;
improvement is welcome.
Another suggestion is to try to have the encoder restart seamlessly,
though it would take a significant amount of work to be able to make it
do something like that properly, and it sort of assumes that encoder
failures are sporadic, which may not necessarily be the case with some
hardware encoders on some systems. It may be better just to use another
encoder in that case. For now, seamless restart is ruled out.
Allows the ability to group scene items. Groups internally are
sub-scenes, which allows the ability to add unique filters and
transforms to each group.
Adds a simple signal reference counting function
(signal_handler_connect_ref) that makes it so that signals keep the
handler around until the all the signal itself is disconnected. This
prevents potential crashes where a signal might try to disconnect after
a handler has already been destroyed (typically in C++ with
OBSSignalHandler helper objects, where destruction isn't guaranteed to
be predictable).
This also modifies OBSSignalHandler to use the reference-counting
connections.
Adds obs_add_raw_video_callback() and obs_remove_raw_video_callback()
functions which allow the ability to get raw video frames without
necessarily needing to create an output.
(Note: This commit also modifies UI and test)
This makes it so that main preview panes are rendered with the main
output texture rather than re-rendering the main view. The view will
render all objects again, whereas the output texture will be a single
texture render of the same exact thing.
Also fixes some abnormal artifacting when scaling the main preview pane.
Adds circlebuf_push_front_zero and circlebuf_push_back_zero to
conveniently push zeroed data to the front/back of the buffer without
having to create an intermediary buffer to accomplish the same thing.
