H.264 in Matroska can have blocks with unordered timestamps. Without passing these as the presentation timestamp into the FFmpeg decoder, the frames will not be returned in chronological order. VideoFrame will now include a timestamp that is used by the PlaybackManager, rather than assuming that it is the same timestamp returned by the demuxer.
