How to recover camera images without restart nvargus-daemon

R35.4.1

  1. I have a serdes with four image inputs(vc 0-3).
  2. use nvgst-lanch.1.0 --sensor-id= [0-3] cam play video for sensor

At this point, if one of the camera outputs is interrupted,after the hardware is ready I can only resume playback of that one by systemctl restart nvagrs-deamon,

But this affects the other three outputs. Can I restore one display without affecting the others?

Try the sample userAutoExposure of MAPI. This sample code implement error handling to terminal the APP to avoid daemon crash.
