Scripting Avidemux to Convert to iPod Format

This is a script to be used in conjunction with avidemux's command-line --run option (avidemux2_cli --run foo.js). Save it as mp4.js and try it with this shell script:

for input in "$@"; do
    cp -v "$input" avidemux.input
    yes | avidemux2_cli --run mp4.js
    rm -v avidemux.input
    mv -v avidemux.output "${input%.*}-$$.mp4"
done
