libxine1-ffmpeg 1.1.4-2ubuntu2 (i386 binary) in ubuntu feisty

 This is the xine media player library (libxine).
 .
 Libxine provides the complete infrastructure for a video/media
 player. It supports MPEG 1/2 and some AVI and Quicktime videos out of
 the box, so you can use it to play DVDs, (S)VCDs and most video files
 out there. It supports network streams, subtitles and even MP3 or Ogg
 files. It's extensible to your heart's content via plugins for audio
 and video output, input media, demuxers (stream types), audio/video and
 subtitle codecs.
 .
 This package contains the ffmpeg input plugin for xine, which enables
 xine-based players a large variety of modern audio and video
 codecs. It also includes some other plugins handling mpeg codec variants.
 You most probably want to install this codec.
