--- Comment #36 from Nicolas Dufresne (stormer) <nicolas.dufresne at collabora.co.uk> ---
After more testing, I observed that the problem I see goes away when the
pattern has less complexity (like pattern=18). In that case, the problem was
caused by hidden latency in vp8enc, which can be fixed by setting a deadline.

test-launch "( videotestsrc is-live=0 ! video/x-raw,width=640,height=480 !
queue ! vp8enc deadline=1 ! rtpvp8pay name=pay0 )"

When deadline is 0 (the default) there is no way to guess what vp8enc latency
will be. With the deadline > 0, the latency becomes under control. I don't
think it make any sense to reopen this bug for this, as it's not the same kind
of issues (it's not actually an issue, just a miss-configure pipeline for
live).
