This emulates behaviour from frame buffer 2, but does not handle stats. In contrast to frame buffer 2, all work happens on the same task queue. FrameBuffer3Proxy encapsulates FrameBuffer3 and scheduler behind a field trial WebRTC-FrameBuffer3. This separates frame scheduling behaviour into a few components, VideoReceiveStreamTimeoutTracker * Handles the stream timeouts. FrameDecodeScheduler * Manages the scheduling and cancelling of frames being sent to the decoder. FrameDecodeTiming * Handles the timing and ordering of frames to be decoded. Other changes * Adds CurrentSize() method to FrameBuffer3 * Move timing to a separate library * Does a thread check for Receive statistics as this is now on the worker thread. * Adds `FlushImmediate` method to RunLoop so that video_receive_stream2_unittest can pass when scheduling is happening on the worker thread.
