--- Comment #14 from Thibault Saunier <tsaunier at gnome.org> ---
WHile I believe it is the right thing to do it introduces a big "perf" issue in
NLE/Pitivi where we try to buffer a lot so the playback is smooth later on.
With these patches on "stack changes" in nlecomposition (ie. when we change the
set of elements used by the composition) we end up blocking on the allocation
query, until the downstream queue is drained, meaning that we won't be able to
keep buffering more than 1 stack at a time.

I am not sure how that should be handled, any idea?
