 // RTCVideoEncoder uses a media::VideoEncodeAccelerator to implement a
 // webrtc::VideoEncoder class for WebRTC.  Internally, VEA methods are
 // trampolined to a private RTCVideoEncoder::Impl instance.  The Impl class runs
 // on the worker thread queried from the |gpu_factories_|, which is presently
 // the media thread.  RTCVideoEncoder is sychronized by webrtc::VideoSender.
 // webrtc::VideoEncoder methods do not run concurrently. RtcVideoEncoder needs
 // to synchronize RegisterEncodeCompleteCallback and encode complete callback.
