Suppose you have recorded an Opus stream with -copyts. Then ffprobe -v error -show_entries format=start_time,duration -- recording.opus shows non-zero start_time and possibly huge duration that does not reflect to the file size. I think you get the actual duration of the recording by subtracting start_time from the given duration. Is that intentional and by definition? I tried recording some MP3 streams with and without -copyts, and start_time is then always small non-zero number (0.011995). Why is that? I have not tried all formats, but apparently they vary in this respect.
Try using this together with -copyts -start_at_zero When used with copyts, shift input timestamps so they start at zero. This means that using e.g. |-ss 50| will make output timestamps start at 50 seconds, regardless of what timestamp the input file started at. _______________________________________________ ffmpeg-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
