You could set up a schroot system of 20.04 and install ffmpeg there. See <https://help.ubuntu.com/community/DebootstrapChroot>. To test the older version you would replace the ffmpeg command in your script with something like "schroot -c focal ffmpeg". Or you keep the original command to use the current ffmpeg version.

And when you have finished debugging you uninstall the schroot packege and remove the chroot folder of the 20.04 system.
