Has anyone successfully gotten ffmpeg from fink to successfully encode an avi
file for an ipod? ( I have a nano.).
I found a reasonably nice script (at bottom) which first used "aac" as the
audio codec. That didn't work, so I did an "ffmpeg -formats | grep aac" and
found libfaac. In my vane attempt at using libfaac, I get this error:

If anyone has ANY hints at all, it would be greatly appreciated. I've made a
few mods and retried the script (like deleting "aspect 19:6" or making it 4:3
and none seem to help.
Here's the script:
#!/bin/bash
## ipodvidenc - The iPod Video Encoder for Linux.
## Created by Eric Hewitt, January 9, 2006.
## Released under the GPL. Go nuts.
input_file=$1
echo "What would you like to name the output file (sans extension)?"
read output_file_name
echo "$output_file_name will be located in $PWD. Is this acceptable? [y/n]"
read output_file_loc_permis
if [ $output_file_loc_permis = 'n' ] || [ $output_file_loc_permis = 'N' ]
then
echo "Where would you like to store $output_file_name.mov?"
read output_dir
else
output_dir=$PWD
fi
ffmpeg -i "${input_file}" -f mp4 -vcodec mpeg4 -maxrate 2500k -b 700k -qmin 3
-qmax 5 -bufsize 4096k -g 300 -acodec libfaac -ab 160k -s 320x240 -aspect 16:9
"${output_dir}/${output_file_name}.mov"
thanks, in advanced,
Kurt
