I'l just paste my comment here, maybe someone else sees it.
We also have a problem with audio/video synchronisation with MAG322. With MAG254 and MAG256 no problem. There’s no pattern when it happens. Sometimes streams are working well for more than an hour, sometimes problem starts after a few minutes and sometimes immediately after switching to channel.
We’ve tried with all possible decoding solutions (ffrt, ffrt2, ffmpeg, mpegts, etc.), public firmware, manufacturer firmware, custom firmware, version 2.20.03, 2.20.05, no difference at all. Debugging mode doesn’t show anything suspicious, ffprobe-ing MPEG-TS streams doesn’t show any errors, etc.
VLC and other players - no problem.
Infomir support “cannot” reproduce a problem, but after linking to this thread, they escalated to L2 (developers) right away. I hope they’ll find a quick fix for this since our MAG322 customers have no more patience, neither do I
