[gst-devel] video clocking

I'm looking for an example of how to correctly implement a clock source.

I have written a basic plugin for a camera, and I'm able to display a 
frame from it, but what I (believe) I need to do is to make my plugin 
supply the clock for the rest of the system.

My existing implementation evidently takes too long to supply a frame, 
so even though I supply images, the screen does not change to reflect 
the latest frame delivered. Only the first frame is displayed. (If I 
just update the pixels manually and quickly return the frame, then the 
new frame becomes visible, so I am assuming that it is the delay 
introduced that is the problem.)

Can anyone point me to an example of how to make my plugin act as a 
clock source?

Many thanks,
