Thanks for your help. I switched to glib 2.42.0 and do not see significant
CPU improvement so far.

I remade some perf stat measures  (*http://fpaste.org/145793/50742514/
<http://fpaste.org/145793/50742514/>*)
You can see that the whole pipeline context switch is 0.005 M/sec. udpsrc
(RTP packets reader) take 0.004 M/sec.

Using perf top again I do not see any particular function consuming CPU (
see *http://fpaste.org/145795/45076731/
<http://fpaste.org/145795/45076731/>*) Do you agree with that ?
Adding a small sleep allow me to save 4-5% on udpsrc (see patch in
attachment).

I checked the resulting mkv file. No frames are dropped using the
workaround. I would like to avoid the use of sleep but it looks like I do
not have other simpler solution for the moment.

Please feel free to advice me.
Cheers,
