• ffmpeg how to ignore (skip) errors when concatenate and speed up multiple video files

  3 avril 2016, par user1767834

  I’m trying to concatenate many files from my car DVR but some time ffmpeg fails with "Invalid argument" error.
  My list of files in cf.txt looks like :

  file '2016_0403_170004_098.MOV'
  
  file '2016_0403_170459_099.MOV'
  
  file '2016_0403_170630_100.MOV'
  
  ...

  And I run ffmpeg using next command :

  ffmpeg -f concat -i cf.txt -qscale:v 0 -filter:v "setpts=0.05*PTS" -an e:\MOVIE\all.mov

  After some outputs ffmpeg crushes with message :

  Output #0, mov, to 'e:\MOVIE\all.mov':

  See line :

  cf.txt : Invalid argument

  So, I want to ignore this error (and any other if possible) and continue to process the files.
  Is it possible ?

  yadif : restore speed of the C filtering code
  Always use the special filter for the first and last 3 columns (only).
  Changes made in 64ed397 slowed the filter to just under 3/4 of what it
  
  was.  This commit restores the speed while maintaining identical output.
