The cpu usage of rtspsrc on r32.2 is higher than the rtspsrc on r28.2

I have update the TX2 from r28.2 to r32.2.
I found the rtspsrc of gstreamer 1.14.5 on r28.2 can use more cpu than gstreamer 1.8.3 on r28.2.
The pipelin is

gst-launch-1.0 rtspsrc location=rtsp://admin:a1234567@192.168.1.64:554/ protocols=GST_RTSP_LOWER_TRANS_TCP ! fakesink

Now the cup usage is about 40% which is viewed by top command,however it is less than 20% on r28.2.
The test is used the same ip carema and the same TX2.
So are there some difference in use for gst pipeline between r32.2 and r28.2?
Thanks!

Hi,
Your pipeline does not have NVIDIA plugins. It might be due to deviation between 1.8.3 and 1.14.5.

Also for profiling, please run ‘sudo tegrastats’.

Thanks!
The location of jetson_clocks is changed, I forget to enable it.
Now it is normal
