[QUOTE="mm1352000, post: 801003, member: 82144"] Playback is not smooth - the renderer drops frames badly. Maybe only one or two frames shown every few seconds. No matter what I do I can't figure out why this is. I'm sure it is something to do with bad PCR or PTS, or maybe that there is separate PCR for the audio and video (audio plays perfectly). It would help if you could tell me how to debug PCR/PTS issues. I have printed all the timestamps but they are out of order (in decode order not presentation order) so I find it hard to figure out what is wrong. mm [Edit: playback is smoother when played in GraphStudio, but frames are still dropped.] [/QUOTE]
