libav-tools 6:11.3-3build1 (amd64 binary) in ubuntu wily

 Libav is a complete, cross-platform solution to decode, encode, record,
 convert and stream audio and video.
 .
 This package contains the avplay multimedia player, the avconv audio
 and video encoder, and the avprobe stream analyzer. They support most
 existing file formats (AVI, MPEG, OGG, Matroska, ASF...) and encoding
 formats (MPEG, DivX, MPEG4, AC3, DV...). Additionally, it contains the
 qt-faststart utility which rearranges Quicktime files to facilitate
 network streaming.
 .
 This package replaces the 'ffmpeg' command-line tool that was provided
 in earlier distroreleases.
