Batch Convert .mp4 to .avi with ffmpeg

Question

Running Ubuntu 13.10 with a fully compiled ffmpeg. I know the code for the actual conversion is ffmpeg -i video.mp4 -codec copy video.avi

I just need a plain and simple Bash script to do that for, say, forty or fifty of the .mp4 files.

Solution

If you have a list of file you can use something like:

cat list-of-files.txt | while read file; do ffmpeg -i $file -codec copy ${file%%.mp4}.avi; done

or simply

cd /path/; ls *.mp4 | while read file; do ffmpeg -i $file -codec copy ${file%%.mp4}.avi; done

you can avoid cat using while ..do..done < list-of-files.txt
