I'm following up here, because I found the solution.  I tried running
the command from the command line myself, and saw the following error:

ffmpeg: symbol lookup error: /usr/lib/libavcodec.so.51: undefined
symbol: dlclose

A little googling turned up this thread:

Short version: One of the libraries ffmpeg uses was installed from
livna, and was compiled differently than the one at atrpms.
Incompatible repositories suck.  Swapped it for the one in atrpms and
everything worked great.
