ffmpeg 7:2.5.7-0ubuntu0.15.04.1 (amd64 binary) in ubuntu vivid

 FFmpeg is the leading multimedia framework, able to decode, encode, transcode,
 mux, demux, stream, filter and play pretty much anything that humans and
 machines have created. It supports the most obscure ancient formats up to the
 cutting edge.
 .
 This package contains:
  * ffmpeg: a command line tool to convert multimedia files between formats
  * ffserver: a multimedia streaming server for live broadcasts
  * ffplay: a simple media player based on SDL and the FFmpeg libraries
  * ffprobe: a simple multimedia stream analyzer
 .
 NOTE: It does not contain qt-faststart to avoid a conflict with libav-tools.
       If you need qt-faststart from FFmpeg, install the package qt-faststart,
       which is recommended by this package.
