performance: Use GLsync to wait commandbuffer GPU process on GLCore/GLES #943

Closed karasusan closed 10 months ago

karasusan commented 11 months ago

This PR improves a CPU load of Render thread when using video encoding with OpenGL or GLES. It uses GLSync instead of glFinish to sync GPU and CPU.

Specifically, the process time of UnityVideoTrackSource.OnFrameCaptured is dramatically reduced.
