Hi,
Trying to figure out how to gather performance metrics for the deepstream reference app running the Object_Detector_SSD example. Ideally, I want to be able to track the frame latencies from ingestion until osd.
Following the post: How to measure PGIE latency?, I was able to view latency measurements for only the nvosd0 component. However, I am not able to view the frame latency since the num_sources_in_batch equals 0 inside the latency_measurement_buf_prob function (deepstream_app.c) when there should be 1 rtsp source.
Could you provide pointers to (1) see the frame latency (2) view latencies for more components than just the nvosd?
