// 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.
