[gst-devel] gst-python: how to use BaseSink.set_sync()

Hi,

Thanks a lot for your help.

Ok, now it works! The pygobject doc doesn't mention this.

What do you mean ?
Now that I've implemented a simplistic do_render(), set_sync() does have
an influence over at which speed the buffers arrive. If I set it to
True, they arrive on sync with the clock, while if I set it to False,
they arrive at max speed (eating 100% CPU).

(or perhaps it's just a matter of vocabulary: by speed, you mean
datarate?)

Regards

Antoine.
