It seems that the original ffmpeg has been dropped by Debian for the moment (in favour of the fork libav) but will be back in 15.
Some people seem to think ffmpeg is deprecated or stale: it's not, it's just that in 2011, a group of devs decided to fork it as avcodec (libav).
I use get_iplayer for BBC downloads and that requires ffmpeg for its automated format conversions. So I was a bit surprised to find that a brand new install of Lubuntu 14.04 (LTS) doesn't include ffmpeg.
How can I install ffmpeg?
