If you've got a list of jpegs in files.lis then something like

 for file in `cat files.lis `; do echo ffmpeg -options $file ; done

should do the trick. If the ffmpeg encoding is complex then it might be
cleaner to code a simple script that takes the filename as a parameter and
then call that script with

  for file in `cat files.lis `; do ./myscript.sh  $file ; done
