Well, for me, and may be for many other users, it would be enough to 
see a warning only once: just to know that ffmpeg does not support 
that mode. And this can be implemented very easy by this patch.

Another approach is to make it as you suggest. But this, as I 
understand, will require to add a variable in file or stream context 
structure. If you know how to do that, do ahead. I just don't feel 
myself very familiar with ffmpeg and therefore don't want to add a 
complexity which, I think, is not necessary.

May be the best approach is to make the log subsystem to report some 
kinds of errors/warnings once using a flag like AV_LOG_FLAG_ONCE. But 
this also requires additional complexity in data structures...
