Do you know how to physically transfer the video to the iPod?
I cant seem to figure out how... I dont think I saw it on the thread...
Thanks again!!

ooops wrong reference, it was on the knoppmyth forums, specifically
here:
http://mysettopbox.tv/phpBB2/viewtopic.php?t=6467&postdays=0&postorder=asc&highlight=ipod&start=15
basically the author suggests a two pass use of ffmpeg:
# mpg2ipod
# quick script to transcode to an 5G iPod compatible video file
# requires recompiling of ffmpeg with xvid, and facc enabled
# you can tweak any of the crop, bitrate, etc.
# video size has worked for me up to 480x352
# this does a 2nd pass because it decreases file size greatly
# remove this pass to speed things up
# this was a quick hack, but is works for now
for file in $*

/usr/local/bin/ffmpeg -i $file -cropleft 4 -cropright 10 -deinterlace -vcodec xvid -s 320x240 -r 29.97 -b 384 -qmax 5 -bufsize 4096 -acodec aac -ab 96 -g 300 -pass 1 -passlogfile mpg2ipod_log -f mov $file.pass1.mov

basically the video codec can be xvid ox x.264, the audio codec is aac,
the container format is .m4v, .mp4 or .mov by the looks of it. The other specs are in that thread. I do suggest you read the whole thread, as it
also sets up an RSS service for itunes (so you can just grab new videos
for the ipod) and the transcoding operations amy have been tweaked (the
above was the guy's first try, and may have been changed in his later
posts)
I downloaded a movie made for ipod last night and it played in ffplay,
so i am guessing that I have ffmpeg compiled with the right options.
(Not that I have an ipod, I am just nterested in multimedia and
trancoding)
My ffmpeg use flags are below. I think aac and xvid are the ones that
are really needed here.
