V4L2 latency on NVIDIA Jetson TX2

Thank you, JerryChang. This thread and the ones referred in there contain handy information.

I’m not sure if I understood well where these 2-3 frames of “default latency” are stored. Are they stored along the Camera -> CSI -> VI -> User Space path? Is there any way to reduce this latency, or is it something intrinsic to the TX2 behavior?
