Thanx to all.
What I did is  tedious, but I had no choice.
Double quoting the filenames did not solve my problem.
So, I simply gathered all the filenames (find . -name \*.mkv -o -name 
\*.mp4 -o -name \*.webm)
into a file which I edited and turned it into a script that
removed single quotes, unprintable characters, square brackets, commas, and
replaced all spaces with underscores - of course, used the mv command to 
move
the files to the new names.
I retried the script as follows:



while read f; do
N=`basename "$f" | sed -e 's/mkv//' -e 's/mp4//' -e 's/webm//'`
         /bin/ffmpeg -i "$f" -map 0:a -c:a libmp3lame -ab 320k -ac 2 -y 
$D/$N"mp3"
done < VIDEO_FILES  > FFMPEG_ERRORS 2>&1

And I am still getting parse errors, because ffmpeg is UNABLE to parse 
long filenames.

What makes it even more confusing, the parse error message appears 
within or between the console output
of transcoding a previous file.
