Original commit message from CVS: This is the audio/video sync release. Changed the mpegvideoparser to parse complete pictures. Added the PTS timestamps to the pictures. Added PTS timestamps to the MPEG audio frames. Made the clock a littlebit better. Gstplay now uses two more threads one for video, one for audio playback. Added the first QoS callbacks for the pads. hopefully fix an mmx compilation problem.
