With that, I hope we can focus on the concern raised in the original question. -- View this message in context: http://www.ffmpeg-archive.org/Using-FFMPEG-to-encode-multiple-outputs-in-parallel-doesn-t-work-tp4680420p4680422.html Sent from the FFmpeg-users mailing list archive at Nabble.com. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
