Since it has been several years now and I have never been able to solve the a/v desync issues with my Nexus-S FF card when playing back recordings...
I'm replaying many recordings (actually most of what I watch are recordings ;-) and don't even remember when was the last time I had an A/V desync.
There is one more issue, that seems to be related. On some recordings, here RTL Television with AC3 playback, sometimes single frames seem to be skipped during playback. I watched a recording of "Alarm für Cobra 11" yesterday and could identify at least 6 little jumps.
I have isolated a 20 MByte part of this recording where this effect was clear to see - I can send it by seperated mails or upload it somewhere if someone gives me an URL.
The weird thing: Playing those isolated scenes does not show the effect as people can see if they play the whole recording from the beginning, but rewinding the short clip to a certain point makes it possible to reproduce the problem. And again: This just happens when playing back the AC3 audio track.
Somehow, mplayer is able to detect the areas in the VDR recordings that need extra "padding" to keep the sync. There must be some kind of pattern in the data that the player recognizes and it knows it must insert a null frame. How to go about finding how it works and creating an algorithm.
Best Regards.
