Re: [FFmpeg-user] A/V sync issues & more with MediaPortal recording of ClearQAM

(Completely unrelated: Instead of using "-vf scale -aspect -deinterlace" you should use something like "-vf yadif,scale" or "-vf yadif,scale,setdar".) Complete, uncut console output missing. [...]

VLC can play the file fine also changing sizes during commericals but ffmpeg seems to lose A/V sync the more times it hits a commerical break.

Is this also reproducible without -async 1? If not, please remove it. Please provide a sample that allows to reproduce the problem. Carl Eugen
