--- Comment #2 from Olivier CrĂȘte <olivier.crete at ocrete.ca> ---
The use-case for this is you have a pipeline like "udpsrc ! rtpbin ! decoder !
encode ! rtpbin ! udpsink sync=false", you only use the jitterbuffer to
re-order buffers, not really to remove jitter. So the jb size is very big,
because having a mis-ordered packet means a really ugly gitch, but we want to
send out the first buffer really early. The final receiver has a fully
functional jitterbuffer that will remove the jitter that this may introduce.

I wonder if we could include a bit of this documentation in the property
description so that others who try to implement this kind of pipeline would be
interested.
