• FFMPEG concat cutting audio off after certain clip

  10 avril 2020, par legit_hacker_2000

  So I am creating multiple video clips in Python using FFMPEG, I am then trying to concat these together. I create multiple videos named result1000, result1001 etc, then I create a transition effect I want to layer between these videos. The result1000, result1001... etc concat together perfectly fine, however inserting the transition effect between them causes every clip after the first transition to lose audio.

  



  Creating the transiton

  



  ffmpeg -loop 1 -y -i media/templates/bg.png -i media/swoosh_sound.mp3 -shortest -acodec copy -vcodec libx264rgb output/swoosh.mp4


  



  Creating video clips

  



  ffmpeg -loop1 -y -i image_files/image+str(1000+i)+.png -i audio_files/audio+str(1000+i)+.mp3 -shortest -acodec copy -vcodec libx264rgb output/result+str(1000+i)+.mp4


  



  The ffmpeg_files.txt then looks something like this

  



  file 'output/result1000.mp4'
file 'output/result1001.mp4'
file 'output/result1002.mp4'
file 'output/result1003.mp4'
file 'output/result1004.mp4'
file 'output/swoosh.mp4'
file 'output/result1005.mp4'
file 'output/result1006.mp4'


  



  and the concat command im using is

  



  ffmpeg -f concat -safe 0 -i ffmpeg_files.txt output/no_bg_out.mp4


  



  In console on running the concat comment it will say

  



  [mov,mp4,m4a,3gp,3g2,mj2 @ 000001f289b44c40] Auto-inserting h264_mp4toannexb bitstream filter


  



  for each resultXXXX clip, then as soon as it reaches a transition clip it starts spamming

  



  [mp4 @ 000001aa093ad100] Non-monotonous DTS in output stream 0:1; previous: 13619623, current: 8777816; changing to 13619624. This may result in incorrect timestamps in the output file.


  



  I have read over the solutions mentioned Here but none of them seem to solve my issue. It should be noted that all video clips are created from .mp3 audio files and .png image files.
