This will mess up AV sync and many other things as the demuxer and
application may very well be unaware of this ...
I think we should add a function that takes a list of AVRational and a AVRational
and finds the closest match for that. Its return value should indicate if the
match is exact or approximate
Such function might be usefull for other things as well ...
