Okay, for now I was forced to open a bug report #5882 https://trac.ffmpeg.org/ticket/5882
So far I found this problem on 3 out of 700+ videos, making it fairly rare, but still significant. That means about 0.5% of my videos DO NOT PLAY on iPad/Apple products no matter which encoding settings I use. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
