Yeah,

just don't use gstrtpbin and use udpsrc, gstrtpjitter and gstptdemux
instead (a subset of udpsrc). I've written a bin that does this for this
problem with pretty good results.

gstrtpbin does way too much buffering with the default params; haven't
tested tweaking them.

The same is actually true for rtspsrc (which uses gstrtpbin).

gstrtpbin loads the CPU, that's right.
