Decrease FPS and see it on my display

Please provide complete information as applicable to your setup.

Hi, my problem is: I want decrease fps in my inference but when i try it with caps.set_property(“caps”, Gst.Caps.from_string(“video/x-raw(memory:NVMM), format=I420,framerate=10/1”))

I cant see the results in my screen and i get this issue:

0:01:29.754772650 11648 0x3722a540 WARN nvinfer gstnvinfer.cpp:2288:gst_nvinfer_output_loop: error: streaming stopped, reason not-negotiated (-4)

when i run it without framerate=10/1 i dont have problem, but i need reduce fps and see the inference in my screen

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks

please refer to this topic I want to infer 1 frame per second in deepstream-test5 app
