It is possible for OBS to receive incomplete frames from the compositor if the graphics drivers in use do not support implicit synchronization. The compositors usually try to workaround this issue by waiting all render operations to complete before sharing frames with OBS. However, this has performance implications for the compositors. Similarly, OBS should also make sure that all the rendering operations sourcing the received buffer are complete before returning the respective pw_buffer back to the compositor, or it would risk the image it is working on getting overwritten without some type of synchronization. This change leverages PipeWire's ability to share DRM syncobj fds to implement an explicit synchronization solution to solve the problem described above. The usage of these DRM syncobjs is negotiated with the compositor that OBS is running on. So OBS can still work even if the compositor does not support explicit synchronization.
