Codec copy with -ss before -i and after -i is not documented that it gives different results
Does that make sense? I think it's not documented because no one knows how to explain the results.
because once you do not decode everything from start you basically can not expect to get always (for any container and for any input) frame-accurate results in both cases.
I don't think decoding is being done. The cutting/trimming can be by dropping packets & remuxing. The packets have to be 'opened' to read the PTSs, but I don't think there's actual decoding.
'-ss'-before-'-i' is cutting at the right point. '-i'-before-'-ss' is cutting at the wrong point. _______________________________________________ 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".
