Fixes several issues playing back mpegts with video streams marked as having "still images". For example, see this video which has frames only every 6s: https://s3.amazonaws.com/tmm1/music-choice.ts Changes include: - start playback right away, without waiting for first video frame - do not consider the sparse video stream in demuxer underrun detection - do not require multiple video frames for the VO - use audio as the master stream for demuxer metadata events - use audio stream for playback time Signed-off-by: Aman Gupta <aman@tmm1.net>
