Well, I was wondering why it worked on the command line, but not in the
script. But actually: I read the error message incorrectly. Sorry. :-(

That's not a binary, so "which" won't find it. (Nevermind, you gave
enough info by listing your files.)

I seriously hope you're not running your conversion as root!

This is what I missed to interpret correctly:

It means ffmpeg sees "libx264" in your command line as an output
"file"/URI. Unfortunately, we can't read the complete command line from

(BTW, you merge some arguments, and some not. Even if it works, that's
We need to see the proper *actual* command line used (minus your hidden
output URL). You can add "-loglevel debug", that will (among others)
display ffmpeg's option parsing. But the easiest way is to add the
option "-report" to the command line, and then grab the resulting file
"ffmpeg-20170724-162640.log" (or similar) and show us the top where it
ffmpeg -report [...]

That should give us an indication of what ffmpeg is interpreting.
