An installation of the ffmpeg executable is available on most, if not all, servers. Run “which ffmpeg” from the shell to see on your server.

There are many threads about all of this on these forums, as well as a user here that offers custom installs of these tools on a DreamHost account for a fee. Search for threads with a user name of netbrix (here is just one example)
