Yes, I get this when I type it in the terminal.
ffmpeg version 0.8.10-6:0.8.10-0ubuntu0.13.10.1, Copyright (c) 2000-2013 the Libav developers built on Feb 6 2014 20:53:28 with gcc 4.8.1 THIS PROGRAM IS DEPRECATED This program is only provided for compatibility and will be removed in a future release. Please use avconv instead. Hyper fast Audio and Video encoder usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}...
Use -h to get full help or, even better, run 'man ffmpeg'
and en-ffmpeg, the same thing.
