Did this work before on Mint? (At the very bottom, I believe I did
figure out what the issue is. Check my babbling inbetween anyway.)

means ffmpeg is seeing a mixture of libraries from different builds. It
*may* indicate that ffmpeg is seeing something it shouldn't (unless
this was on purpose).

Can you grab a static build from Zeranoe
(https://ffmpeg.zeranoe.com/builds/) - not the 3.3.2 but rather the
"201707*" version - and use that to check. (We won't uderstand whether
it's the newer version or the proper build that makes the difference

D'uh! Due to the extention of the file, and because your build of
ffmpeg supports libopenmpt, ffmpeg tried to open this as a "module
tracker" (a weird audio format from the 80ies, IIRC.) I think you need
to force the input as some sort of MPEG:
$ ffmpeg -f mpg -i MOV024.MOD
$ ffmpeg -f mpegts -i MOV024.MOD
Zeranoe's build probably doesn't support libopenmpt and will work out
of the box. If it does, do tell us which format it detects (the output
of "ffmpeg -i" please.
