  • FFMPEG creates incorrect Source duration

    13 septembre 2020, par Byron Whitlock

    When transcoding movies from an AVI to mp4 sometimes FFMPEG sets the "Source Duration" incorrectly.

    



    This messes up playback on IOS devices. Specifically, it causes the video to cut out at "Source duration" while the audio still plays.

    



    enter image description here

    



    FFMPEG output transcode doesn't' show anything odd at all. Looks normal, no errors or warnings.

    



      

    • Can I force FFMPEG to never add the "Source Duration" metadata ?

      • 


    • How do I edit the track metadata shown by mediainfo ? I tried Mp4box, and a few others, but I can't seem to figure out how to edit track level metadata.

      • 


    



    Thanks.

    • Can I force FFMPEG to never add the "Source Duration" metadata ?

      • 


    • How do I edit the track metadata shown by mediainfo ? I tried Mp4box, and a few others, but I can't seem to figure out how to edit track level metadata.

      • 


    



    Thanks.

    



    Log is below.

    Edit

    



    This has something to do with data, when I run this command (cut at 10 minutes)

    



    ffmpeg.exe -i CI.mp4 -ss 00:00:00 -t 00:08:00 -vcodec copy  -map_metadata 0 -acodec copy CI2.mp4


    



    Mediainfo shows

    



    Duration                    : 9mn 49s
Source duration             : 2mn 40s


    



    When I run this one (18 minutes)

    



    ffmpeg.exe -i CI.mp4 -ss 00:00:00 -t 00:18:00 -vcodec copy  -map_metadata 0 -acodec copy CI2.mp4


    



    Mediainfo shows

    



    Duration                    : 17mn 49s
Source duration             : 3mn 30s


    



    How can I edit the metadata directly
