Adds a video source for OBS Studio using libmpv.
Things left to note/fix
- Maybe add option to load a custom mpv.conf file and the option to set mpv properties/settings
- Add option to set behavior for player when source is inactive
- Audio control
- MPV does not seem to offer any way of retrieving raw audio via a callback
- On linux the source creates a jack audio capture and tells mpv to connect to it this works well and allows us to control and filter the audio in obs, however it does depend on jack or pipewire working. An option to choose beteween the different audio backends (oss, sndio, alsa, pulse, jack and pipewire) might be useful.
- Windows just plays audio through the default audio device
- MPV does not seem to offer any way of retrieving raw audio via a callback
- The interact GUI works only for mouse movements, it does not react to clicks
- On Windows both Direct3D and OpenGL backends of OBS are supported, if Direct3D is used the plugin will try to use the WGL_NV_DX_interop extension, which allows sharing of textures between Direct3D and OpenGL. If the extension is not supported the textures will be copied, which is less efficient.
