Thanks for your comments. The use of sleep is definitely not a solution. It was
used for me to understand how we could save some CPU in udpsrc thread.
I added rtpstats module. Having lot of camera (8) lead to packet dropped using
the sleep even increasing buffer sizes.So definitely this is not a solution.
Using same cameras we used libav module. On each camera it consumes around 5%
while it consumes around 12-15% with gstreamer. It also works fine with 8
simultaneous cameras. It proves that some improvement regarding CPU
consumption in gstreamer.
I have to admit that I have issues to investigate gstreamer cpu issues.
Profilers so far did not point to something relevant. As udpsrc thread is the
major consumer, I should investigate it. Any help or advice would be helpful.
We have to find a solution soon so it looks like we will use libav if we don't
have significant improvement.
