do you need to check the raw data from camera? if yes, you should dump the memory which store the camera data

Hi，

It is yes，I try to dump memory after V4L2 dequeue operation，does it the pure camera data not pass through i.MX8 ISI？

Thanks

you can send the camera data to memory, then read the raw data from memory,don't dump memory after v4l2
