--- Comment #10 from Jan Spurny <jspurny at seznam.cz> ---
You spotted the problem - I was reporting the framerate into our system on
GST_EVENT_CAPS in our element as "default-fps" so our system knows immediately
what to expect.. this could be a bit problematic with computing framerate,
because if I want some precision, I would have to wait at least a few seconds
to compute the framerate which would slightly break our system which expects
(and needs) to know the framerate before first frame (or more precisely, before
second frame) arrives. I made a quickfix and just replaced this with fixed
"12.0", but you probably see that this is not a long term solution..

But that's my problem - I shouldn't have designed it that way - I'm just
writting that so you'd understand why I won't let it go :)

Anyway, my problem is mine, and has nothing to do with GStreamer. But I still
feel it's not right to have 0/1 (=unknown) framerate if it actually IS known..
