libav-tools 7:2.8.4-1ubuntu4 (arm64 binary) in ubuntu xenial

 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 is a transitional package that provides the following links:
  * avconv -> ffmpeg
  * avplay -> ffplay
  * avprobe -> ffprobe
 This package can be removed, when nothing uses the av* program names anymore.
