How apropos! * I've been trying to do essentially this for years- it was the reason I subscribed to and posted to this list initially. It would be great to have a mode which has the frame-exact + sync nature of a re-encode, without the re-encode! The trouble I've run into the few times I've tried it is that when I try and glue the parts back together via concat, things do not work nicely. Perhaps if there were a way to replicate all the codec properties of the original stream when re-encoding, it might work; but it's also possible that something else like PTS would throw it off. Rob * typed and posted while waiting on ffmpeg to visually "losslessly" re-encode so that I can do a frame exact cut, currently at 0.601x realtime _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
