Hi all,
I had to resort to doing one file at a time, albeit within a script, which
does not flood ffmpeg with a huge list of files,
Rather, the filenames are read one at a time from a list of short 
filenames - such as F_000  F_001 ...etc,
like so:

For F in F_[0-9]*; do
vidfilename=`cat $F`
ffmpeg ....etc....
done

This way, ffmpeg is not getting confused by a tsunami of stdin
