The ffmpeg program is only provided for script compatibility and will be
removed
in a future release. It has been deprecated in the Libav project to allow
for
incompatible command line syntax improvements in its replacement called
avconv
(see Changelog for details). 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'
