I have the following pipeline:
camera-1 \ ---> muxer -> pgie -> tracker -> sgie1 -> sgie2 -> app_sink / camera-2
The app_sink call a function that trigger external hardware based on the result of of sgie1 & sgie2 on detected object. We measure the latency from the time the images were captured at the camera to the time the external hardware receive the instruction.
When sgie1 & sgie2 are included, the latency range from 68ms to 80ms, however, when we removed sgie1 & sgie2 the latency does not change as much and range from 50-53ms. What could be the cause of large latency jitters when SGIEs are added?
