qt-faststart 7:2.5.1-1 (armhf 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 qt-faststart, a utility that rearranges a Quicktime
 file such that the moov atom is in front of the data, thus facilitating
 network streaming.
 .
 NOTE: It diverts the qt-faststart from libav-tools to qt-faststart.libav.
