Enable Perf measurement(FPS) for deepstream-test3-app not working

Hi all !
I am working with enable Perf measurement(FPS) in deepstream-test3-app.
I follow Enable Perf measurement(FPS) for deepstream sample apps, make file success but just print

**PERF:

How can i fix it? Thank so much

This is code i modified:

What’s your command like?

i run with command:

./deepstream-test3-app file:///opt/nvidia/deepstream/deepstream-6.0/samples/streams/sample_1080p_h264.mp4

Could you try to set the third parameter of enable_perf_measurement to the number of sources?

I change the third parameter from argc-2 to num_sources
Thank you
