  • FFMpeg Concat Error - What needs to be changed ?

    19 avril 2018, par Andrew Baldinger

    I have a tv episode video (let’s say episode.mp4). I also have a short, 20 second closing credit video that I want to append to various episodes (let’s say closing.mp4) The episode and closing are always Mp4, h264. The frame sizes are also the same. The audio codecs do vary, though. I would like to concat using concat demuxer to avoid having to re-encode. I tried doing this, but it gives me an error. I would like to make any necessary encoding changes to the short closing clip (so I would create multiple closing files, each matching the main episode file I want to add it to). What do I need to additionally make sure matches with the two videos to be able to use concat demuxer ? How would I edit the closing clip to match the episode ?

    Here is a probe of the ending clip :

    I created a version of the ending with the same screen size and audio codec as the episode. But, when I try to concat, the resulting video is much longer (1:03:00) than it should be (about 42 mins), and it freezes when played. Here is the concat :

  • How to check video integrity with ffmpeg ? [on hold]

    20 août 2017, par Shreeyash Motiwale

    I recently downloaded a cartoon series called Dragonball Z, but many of the videos are broken. After some research I found ffmpeg which can check video integrity. It does it one at a time. Can I do it at once in a bulk ?

    COMMAND

    ffmpeg -v error -i Dragon-Ball-Z-Episode-1.mp4 -f null - 2>error.log

    this works fine but only one at a time

  • Splitting video in multiple episodes with ffmpeg [migrated]

    12 juin 2013, par Alex Smolov

    I need to cut one video into multiple pieces with ffmpeg.

    When I cut just one episode

    ffmpeg -i 001.mp4 -vcodec copy -acodec copy -ss 00:00:00.000 -t 00:00:25.500 -strict -2 out1.mp4

    or

    ffmpeg -i 001.mp4 -vcodec copy -acodec copy -ss 00:00:25.500 -t 00:00:33.750 -strict -2 out2.mp4

    my video is cut instantaneously.

    But when I chain markers where I'd like to cut

    ffmpeg -i 001.mp4 -vcodec copy -acodec copy -ss 00:00:00.000 -t 00:00:25.500 -strict -2 out1.mp4 -ss 00:00:25.500 -t 00:00:33.750 -strict -2 out2.mp4

    it still works, but it takes considerably more time (about 10 sec), and I see the same output as when I convert something.

    Is something wrong with my ffmpeg-command, or it is better to execute ffmpeg-commands one by one ?
