Hello everyone,
I'm programming V4L2 using Linux 4.19.35, on an evaluation board MCIMX8QM-CPU.
The camera uses MX8X MIPI4CAM2.
So the question is, is it possible to use the V4L2_MEMORY_USERPTR feature of V4L2?
Or, if you have a sample source somewhere, please let me know.
Currently, I can capture using V4L2_MEMORY_USERPTR, but when I look at the capture screen, it is black. We are currently investigating at what level the black screen is displayed.

Hi aso
one can look at unit tests example : V4L2_MEMORY_USERPTR
can be used for i.MX8M, but not with i.MX8QM:
Best regards
