Didn't read the code closely enough, I thought denominator was passed as the
denominator sorry.

We have a similar problem in GES, when trying to render a ogv from two ogvs
with a transition, oggdemux produces a segment with start equal to 0 and stop
equal to the duration of the file source, where matroskademux doesn't have the
same behaviour. I don't know what the correct behaviour is, but I think that
segment ought not to be emitted in these circumstances.
