  • 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 ?

  • Ffmpeg I/O error

    11 septembre 2011, par David542

    I am trying to get info on a file. I can this on either a file or url on my local machine. However, when using my server, I can only get info on a file. This is what happens when I try a URL :

Usually that means that input file is truncated and/or corrupted.

    However, the file is not corrupted, as this works fine on my local machine. What do I need to do to fix this ? Thank you.
