You posted:

# apt purge ffmpeg
# apt autoremove
# apt install ffmpeg

but you didn't show your working. You should check out what happened
by looking at /var/log/apt/history.log to see if libopenal1 was
affected by this command sequence. For a start, other packages might
depend on libopenal1, preventing its auto-removal.

Then of course there's the investigation of why it wasn't
installed correctly in the first place, and what was happening
during the "several attempts" at installing ffmpeg.

Cheers,
David.
