Timestamp problem...

[Eric Trousset]

Hi,
I m back on the project. 
I've been investigating more this morning and actually, its seems I can manage to display buffer correctly if I don't go thru the videomixer element. 

So I wonder if it can have to do with video rate handling in videomixer?

Concerning the clock I now have one ok. Just the first time the create function is called, and the state is still PAUSED, I have no clock. What should I do in this case?

Regards, 
Eric
