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:firstname.lastname@example.org: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？
