[gst-devel] Possibility to sync parallel pipelines?

I am developping a video mixing application, based on clutter. Since
the three pipelines are started sequentially (without
synchronization), their framerates produce a 3 times bigger framerate
in the video compositing app, resulting in bad performance. For
instance, for one single video stream, the app produces 25 fps
(perfectly normal, since the source is 25 fps). However, if i display
3 different streams, the framerate goes up to 90 fps.

Therefore, i'm thinking of trying to synchronize the three pipelines;
is it possible for the pipelines to share the same sink "clock" ?
These are custom pipelines.

Thanks in advance,
