Yes, the very first ffmpeg output shows:

> Parse error, at least 3 arguments were expected, only 1 given in string 'omplete_Discography/THE SMITHS · Meat Is Murder · FULL ALBUM HQ AUDIO-Dod4KC9_X4Q.webm'

Without seeing the script which is doing this, I suspect something is
'piping' these strings into ffmpeg, which is trying to interpret them
as debug commands.

You (JD) can disable that ffmpeg feature using the command line option
"-nostdin" (which I consider a good idea for batch processing), but you
should rather fix the script.
