​Thanks - that is somewhat a panacea, especially if one
is not 50% or more into the transcoding - so that issuing
a 'q' will not lose too much is only say the transcoding is
into 10 minutes of the video.

Now how about ffplay? I mean is/are there options
to ffplay that would allow the playing of the unfinsihed
mp4 file (without quitting the trancoding)?
