• ffmpeg image sequence from text file not rendering correctly

  4 juillet 2018, par Rich

  I’ve been working with ffmpeg and I have got it to work perfectly quite a few times, but as of recent I am running into an issue where all the images from my text file arent used.

  My text file looks like -

  ffconcat version 1.0
  
  file 'gallery-house-77-west-55th-street-01.jpg'
  
  duration 4.44
  
  file 'img03.jpg'
  
  duration 4.44
  
  file 'inside.png'
  
  duration 4.44
  
  file 'placeholder.png'

  (amount of files, file names and extensions will always vary)

  And I’ve tried several combinations but as of now my ffmpeg function looks like —

  ffmpeg -i audio.mp3 -safe 0 -f concat -i paths.txt -c:a copy -c:v libx264 \
  
  -vf "scale=1280:720:force_original_aspect_ratio=decrease,pad=1280:720:(ow-iw)/2:(oh-ih)/2,fps=25,format=yuv420p" -vsync vfr -movflags +faststart -y output.mp4 2>&1');

  When trying to run it, the video seems to convert but has various weird behaviors - sometimes only the middle file(image) in the list is shown or the first 2 only are shown/rendered.

  The audio is playing correctly though.

  I’ve tried setting the framerate for the input and I also tried setting it for the output but it leads to more strange behavior.

  This is what is echoed when running my above ffmpeg command -

  Any ideas whats causing the image sequence to fail ?

  EDIT

  After some more debugging I think it may be related to the fact that all the files dont have the same extension. How can I make it so that it doesn’t have to be that way or is that already a default setting and the issue is else where ?

  But I get a video with no audio in QuickTime. I think its a problem of the output container (mp4) not supporting mp3. What output container might be best ? Due to quality loss, I am reluctant to convert the mp3 to another format. If my audio is mp3, what might I change about this ffmpeg command ?

  The final destination is YouTube.

  Does anybody know what could be wrong ?
  Just to be clear, I recompiled ffserver and ffmpeg for android. They both seem to be ok as I can execute commands. Both binaries are part of the app, so everything runs inside the phone.

  Thanks.
