I am posting it here because this likely affects all Ubuntu 14.04 installs.

I had to install the original ffmpeg from a PPA to fix the issue. Apparently Ubuntu 14.04 includes libav instead of the original ffmpeg, and they are not 100% compatible.

Avconv version 9.18-6:9.18-0ubuntu0.14.04.1, Copyright © 2000-2014 the Libav developersīuilt on 13:19:10 with gcc 4.8 (Ubuntu 4.8.2-19ubuntu1)Įrror splitting the argument list: Option not found
