*I* tried (not an OP).  It did not "become obvious why that can't work".

Moreover, -vf cropdetect worked on the stream...  So what was your
suggestion about?  Using cropdetect with sstep looks like a very
useful idea...

============================================

BTW, after play stops, could -vf cropdetect emit a "-vf crop=" line
based on *combined* stats of what it saw?  This would simplify
automation of mencoder so much...

Thanks,
