Note that this is old and that you are expected to always post
command line and complete, uncut console output when asking
for support.

FFmpeg can accept stdin for control, this disables it (and seems
unrelated to your isssue).

you test.)
Since this behaviour exists since at least 2009, I don't
think so.
