Nicolas,
I would like to know more about the idea you mentioned in:
https://bugzilla.gnome.org/show_bug.cgi?id=793707#c18

"
Question, if upstream was to "commit" it's decided allocation, would that help
? In recent research, we found that delaying allocation to when first buffer
comes increases startup latency (specially with CMA), so it's something we are
considering, optional of course, for backward compatibility. To help
understand, this would mimic the caps query followed by caps event model.
"
Do you mean we can get the pool from v4l2 in the downstream element?

Wondering how we can get the list of FDs allocated by v4l2 in msdk element.
