Check real FPS from NDI source

Question

I have NDI source self-written with NDI SDK. I send frames with predefined FPS (25, 30, 50, 60). I can view this stream with NDI Studio Monitor or OBS Studio. But I can't check real FPS. Could someone tell me how I can check the FPS on the some receiver?

Answer 1

I have been looking into this too without any success to date. My thought was to use a fps counter for a game, but they don't seem to be able to access that data from NDI Studio Monitor.

My guess as to the reason is that the NDI decoding is a CPU based task and those frame counters are expecting GPU's, on-board or external, to do the task of rendering frames.
