  • Adding cover art to video wtih chapters and chapters getting deleted

    31 mai 2021, par throwaway513

    I am trying to add a cover art to a video with chapters.

    


    I added 2 chapters to a video using :

    


    ffmpeg -i 1.mp4 -i Chapters.txt -map_metadata 1 -c copy 2.mp4

    


    but when I try to add cover art it deletes the first chapter and only keeps the second ?

    


    ffmpeg -i 2.mp4 -i image.jpg -map 1 -map 0 -c copy -disposition:0 attached_pic 3.mp4

    


    I also tried mp3tag but the picture doesn't show on the file after adding chapters through ffmpeg. Chapters work fine on 2.mp4 but on 3.mp4 it deletes the first chapter. It also deletes the chapter when I do ffmpeg -i 2.mp4 -c copy any.mp4

  • Losing audio quality when merging multiple videos with FFmpeg

    30 mai 2021, par Charly

    I am trying to merge multiple videos (a few seconds each) into one, using FFmpeg.

    


    Merging all at once

    


    I first tried merging all videos with one FFmpeg command, but it only seems to work with up to a certain amount of videos. On my Raspberry Pi 4 (2BG RAM), it worked for 16 videos and broke (ran out of memory ?) while merging 36 videos (command and ouput below)

    Merging videos 2 by 2

    


    I then tried gradually merging videos into one, using multiple FFmpeg commands.

    


    # Pseudocode
final = merge(clip1, clip2)
final = merge(final, clip3)
final = merge(final, clip4)
final = merge(final, clip5)
...


    


    with each command, looking like this :

    


    ffmpeg -i 1Rbrdn1Xp.mp4 -i G7eYqdFPb.mp4 -y -filter_complex concat=n=2:v=1:a=1 -vsync 2 UMVDl9jki.mp4


    


    ffmpeg -i UMVDl9jki.mp4 -i -Xo-6ABm3.mp4 -y -filter_complex concat=n=2:v=1:a=1 -vsync 2 azE1Uombp.mp4


    


    This works but there is a loss in audio quality on the first clips, and it is slowly improving over time. I am guessing this is due to the first videos being merged more times than the last ones. You can see this effect happen in this video (weird artefacts in the voice).

    


    


    So, am I doing something wrong ?
    
Is there a way of merging a lot of videos, without running out of memory or worsening the audio quality ?
