 // VideoTrackRecorder is a MediaStreamVideoSink that encodes the video frames
 // received from a Stream Video Track. This class is constructed and used on a
 // single thread, namely the main Render thread. This mirrors the other
 // MediaStreamVideo* classes that are constructed/configured on Main Render
 // thread but that pass frames on Render IO thread. It has an internal Encoder
 // with its own threading subtleties, see the implementation file.
