SUMMARY = "A complete, cross-platform solution to record, convert and stream audio and video."
DESCRIPTION = "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."
