[Bug 754189] payloaders: memory performance

[GStreamer (GNOME Bugzilla)]

--- Comment #5 from Sebastian Dröge (slomo) <slomo at coaxion.net> ---
It probably makes sense to try if using a mtu-sized buffer pool improves
anything in the payloaders. Main problem here is going to be that you then
actually need to *copy* the payload instead of creating "subbuffers" as many
payloaders do now. Or you could create a buffer pool of RTP-header sized
buffers and only attach the payloader "subbuffers".

This needs careful testing to see how well it works and if it actually improves
something in general or makes things worse in other situations.


For the mapping, a GST_RTP_MAP_CHECK_NOTHING definitely makes sense in the
payloaders. That probably improves performance a bit without adding any risk of
making things worse.
