• ffmpeg works manually but not with cron ?

  2 mai 2017, par mdnba50

  I can successfully convert mp3 + audio to mp4 when i run the script manually.

  exec("/usr/bin/ffmpeg -loop 1 -i $destination_thumbnail -i $input_file -c:a copy -c:v libx264 -shortest $videoPath 2>&1",$output);

  When i have the above code in a script executed via cron it doesn’t convert. I get this error.

  Why does this work when i manually execute the script in conversion.php but when i run conversion.php via cron i get the above error ?

• FFMPEG mp4 copied to matroska loses last frame

  16 juin 2020, par Mike

  I am running this simple ffmpeg command to change an mp4 video to matroska format so it can support streaming. ffmpeg -i test.mp4 -c copy out.mkv. My issue is that the out.mkv file has one less frame than the original mp4 file. It seems to be missing the last frame.

  



  I thought using copy as the codec should retain the same video. Am I missing passing an option to FFmpeg ? Thanks.

  What should I do in order to fix this ? I've already tried to add -fflags +genpts in the beginning but it fails anyway.

  


  EDIT : I did solve it by using MKVToolNix instead.
