This support is needed if there is a big delay between the creation of frames and the time they are delivered to the WebRTC C++ layer in AndroidVideoTrackSource. This is the case if e.g. some heavy video processing is applied to the frames that takes a couple of hundred milliseconds. Currently, timestamps coming from Android video sources are aligned to rtc::TimeMicros() once they reach the WebRTC C++ layer in AndroidVideoTrackSource. At this point, we "forget" any latency that might occur before this point, and audio/video sync consequently suffers.
