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.
- 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
- Add some temporary streaming code using FFmpeg. FFmpeg itself is not
very ideal for streaming; lack of direct control of the sockets and
no framedrop handling means that FFmpeg is definitely not something
you want to use without wrapper code. I'd prefer writing my own
network framework in this particular case just because you give away
so much control of the network interface. Wasted an entire day
trying to go through FFmpeg issues.
There's just no way FFmpeg should be used for real streaming (at
least without being patched or submitting some sort of patch, but I'm
sort of feeling "meh" on that idea)
I had to end up writing multiple threads just to handle both
connecting and writing, because av_interleaved_write_frame blocks
every call, stalling the main encoder thread, and thus also stalling
draw signals.
- Add some temporary user interface for streaming settings. This is
just temporary for the time being. It's in the outputs section of
the basic-mode settings
- Make it so that dynamic arrays do not free all their data when the
size just happens to be reduced to 0. This prevents constant
reallocation when an array keeps going from 1 item to 0 items. Also,
it was bad to become dependent upon that functionality. You must now
always explicitly call "free" on it to ensure the data is free, and
that's how it should be. Implicit functionality can lead to
confusion and maintainability issues.
- Fix a bug where the initial audio data insertion would cause all
audio data to unintentionally clear (mixed up < and > operators, damn
human error)
- Fixed a potential interdependant lock scenario with channel mutex
locks and graphics mutex locks. The main video thread could lock the
graphics mutex and then while in the graphics mutex could lock the
channels mutex. Meanwhile in another thread, the channel mutex could
get locked, and then the graphics mutex would get locked, causing a
deadlock.
The best way to deal with this is to not let mutexes lock within
other mutexes, but sometimes it's difficult to avoid such as in the
main video thread.
- Audio devices should now be functional, and the devices in the audio
settings can now be changed as desired.
Having everything in global.ini meant that if you wanted different
settings for studio mode, that it would also overwrite it for basic
mode. This way, the settings for each mode are separate, and you can
use different settings for each mode.
FFmpeg test output wasn't make any attempt to sync data before. Should
be much more accurate now.
Also, added a restart message to audio settings if base audio settings
are changed.
Resetting audio while libobs is active is a real pain. I think I'm just
going to do audio resetting later, or maybe just require restart
regardless just because having to shut down audio streams/lines while
there's sources currently active requires recreating all the audio
lines for each audio source. Very painful.
Video fortunately is no big deal, so at least there's that.
Implement a few audio options in to the user interface as well as a few
inline audio functions in audio-io.h.
Make it so ffmpeg plugin automatically converts to the desired format.
Use regular interleaved float internally for audio instead of planar
float.
This allows the changing of bideo settings without having to completely
reset all graphics data. Will recreate internal output/conversion
buffers and such and reset the main preview.
There were a *lot* of warnings, managed to remove most of them.
Also, put warning flags before C_FLAGS and CXX_FLAGS, rather than after,
as -Wall -Wextra was overwriting flags that came before it.
- 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.
- Move over the last of the original settings dialog code to QT. It was
actually a bit easier to write in the QT version. wxWidgets was
definitely not ideal for that because the pages would fully
create/destroy every time.
- [Win32] Fix os_dlopen so that it only appends .dll if not present
- [MacOS] Fix name dialog text edit widget issue (it would be better if
we could just use the list widget for editing labels, will have to
look in to that in the future)
- Tweak the settings UI a bit more and make 30 FPS default
- Add a macro to convert a QString to a UTF-8 const char * string
- Rename build/plugins to build/obs-plugins
- Remove the last of the wxWidgets code
- Fix the size issue with list boxes on mac. Was displaying the list
boxes with an improper size. Turns out it was just the wrong size
policies on the frame below.
- Ensure the main windows are fully displayed *before* initializing
subsystems. This ensures that the graphics system will properly start
up on macos, and allows the glitch fix.
- Made a workaround for weird QT glitch that would happen to the parent
of a pure native widget that also has internal painting fully
disabled. (Should definitely write an example and report this bug on
the QT forums)
- Had the wrong names set for the up/down widgets for sources/scenes
- Updated the settings dialog and gave most of the widgets actual object
names
- Added code for the settings window. Settings window should now at
least display.
