libavformat-extra 7:4.4.2-1ubuntu1 (s390x binary) in ubuntu kinetic

 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 metapackage depends on the latest version of the libavformat variant
 that offers additional (de)muxers support. Application packages can depend
 on it if they require or suggest this variant in a robust manner.
