Thanks for the response.  There are 2 options for ipod video -- H.264 and
MPEG-4:
Here are the specs from the apple site:

H.264 video: up to 768 Kbps, 320 x 240, 30 frames per sec., Baseline Profile
up to Level 1.3 with AAC-LC up to 160 Kbps, 48 Khz, stereo audio in .m4v,
.mp4 and .mov file formats

MPEG-4 video: up to 2.5 mbps, 480 x 480, 30 frames per sec., Simple Profile
with AAC-LC up to 160 Kbps, 48 Khz, stereo audio in .m4v, .mp4 and .mov file
formats

>From what I can tell, the ffmpeg above is using MPEG-4.  Not sure if the
H.264 would be any easier (I already have installed the libx264 from svn).
