• FFMPEG - Images to Video

  24 mars 2014, par Mahesh

  ffmpeg -f image2 -r 15 -i images/img%03d.jpg -vcodec libx264 video.mp4

  I run this code with exec in php.

  I am not getting the output. The video.mp4 is blank.

  However if i modify this commade to something like this,

  ffmpeg -f image2 -i i.jpg -vcodec libx264 -t 15 video.mp4

  The video is running for 15 seconds.

  I tried -r 1/15. It is not working too.
  Where do i do the mistake ?

  <?php
  
  $command = "/usr/bin/ffmpeg -f image2 -r 15 -i images/img%03d.jpg -vcodec libx264 video.mp4";
  
  exec($command);
  
  ?>

  images folder has img001.jpg img002.jpg ... img005.jpg

• Error concatenating two files with ffmpeg ubuntu

  3 janvier 2014, par Dan Ramos

  The following command works fine in OS X :

  ffmpeg -f concat -i videos_playlist.txt -c copy final.mkv

  But when I try to run it on ubuntu i get the following :

  Unknown input format: 'concat'

  Any idea what I'm missing or a possible work around ?

  So, what is the configuration issue for ffserver, or may be it is a bug of the ffserver ?

  UPD. I have realized, that i fed file1.ffm instead of file.ffm ; that caused some ffserver problem :
