“deepstream_test1_rtsp_in_rtsp_out.py” run extremely low frame rate in multiple rtsp stream input. If in single rtsp input, frame rate will be fine.

I have tried other script like deepstream-test3, runtime_source_add_delete. This problem will not occur.

deepstream-test3 and runtime_source_add_delete are all using eglsink which depends on the display drive and HW, deepstream_test1_rtsp_in_rtsp_out is using udpsink which will depends on the network stack. You may try to replace the udpsink to fakesink and try to measure the FPS.

I finally set streammux.set_property("batch-size", number_sources) to solve the problem. L310
