Previously we passed the wrong display and formats/modifiers could not
be queried. This prevented pipewire sources from negotiating texture
sharing on x11.
- Don't repeatedly query version at runtime in case a user installs the
SDK while OBS is running
- Restore default DLL search directory
- Don't show outdated SDK message if the SDK is not found
- Protect minimum version macro with brackets
Previously, `custom_size` was checked at the end of the `scene_load`
function. If the scene contained no "items" array, the `custom_scene`
loading code would never be run.
This moves the `custom_size` code above the return statement.
-Wformat-security is enabled, some Linux packages build system have it
enabled.
https://github.com/obsproject/obs-studio/pull/5766
-Wunused-parameter is enabled too.
Also ensure that null conversion (C++ only for GCC) is enabled because its
enablement by default can depend on the CMake generator.
-Wswitch is enabled but it is kept as a warning. It was already enabled
with Clang.
If Clang has -Wshorten-64-to-32 enabled, keep it as warnings.
There was quite a bit of conflated usage of mixes (which refers
to raw audio) and encoder counts. This fully separates the two
and makes a distinct separation when iterating over mixes vs
encoders.
Previously, an output that does not implement `info.get_output_type`
would result in these log messages saying `(null)`. This uses the actual
ID directly from the output itself instead.
Also removes two extra calls to `obs_encoder_set_video()` as they are
redundant and unnecessary.
OBS has been logging `1 views remain at shutdown` when in reality there
are not technically any views remaining. When views are removed, the
view itself is destroyed immediately, but the mix remains, to be
garbage collected by the graphics thread.
In this case, the view has already been removed, but the graphics
thread has not run an interation and cleaned up the mix, so this
log message appears.
Fixes the issue by checking if a mix actually has an assigned view,
instead of blindly logging existing mixes.
There is currently no way to clear a video_t or audio_t object from an
encoder once applied. `audio_t`/`video_t` objects can be destructed at
any time, and it is dangerous to prevent these object references from
even being cleared.
This does not fix the issue where destroying an audio/video object does
not clear the reference from all subscribed encoders.
Protect `obs_encoder_set_video()` and `obs_encoder_set_audio()` from
being used if the encoder is active. Changing these values while active
is undefined behavior.
The DAL plugin-based virtualcamera shares data between OBS and the
plugin using an IOSurface. IOSurface locks are necessary to ensure
race conditions between data generation (OBS side) and consumption
(virtual camera side) and also that an IOSurface is not offloaded to
GPU memory when it is indeed needed in CPU memory.
Also moves the invalidation of the NSMachPort for the frames to after
the IOSurface data has been converted into a pixelbuffer and added to
the frame queue of the virtual camera, as an early invalidation will
cut off access to the pixel data shared with the DAL plugin.
