Thank you, Jim. Yes, I understand now. FFmpeg is not waiting for a
specific command. It accepts _all_ stdin, no matter whether an option
that expects commands is employed, or in fact whether there's any
options at all, and it silently disposes of stdin that is not a command,
and apparently continues to do so until stdin is empty. Oh, that's just
*ducky*.

I was vaguely aware of FFmpeg commands but had no idea that they are so
global and 'thoughtless', 'unthinking'. Wonderful! ;-(

What I have learned: To forevermore submit "start ffmpeg" instead of
"ffmpeg".

Thanks again!--Mark.
