I strongly support this patch, it will really help the average user to
produce streams which plays correctly on most decoders. I agree that it
can produce invalid streams because of a too big bitrate in some cases,
but I think it will be rare. And it is possible to detect the situation
and warn the user if this happens before or after the encoding,
depending on the arguments (I guess that it the --bitrate or
--vbv-bufsize options are used, it is possible to known in advance if
the MaxBR and MaxCPB restrictions will be met with a good probability,
correct me if I'm wrong, I don't understand well the rate control part
of the encoder).

I hope it can be applied.

Best regards
