HI
I now hope that the v4l2 driver of imx8dx can support the format of V4L2_PIX_FMT_NV21, how do I need to modify it to achieve this function. I see that the driver already supports the V4L2_PIX_FMT_NV12 format.
Thanks!
I don't know capture or output you mean, I assume that you mean capture, so do you mean your input video is format NV21?
HI
Yes, it is capture, I am using AHD to mipi chip bridge, I see that 9 capture formats are already supported in the imx8-isi-cap.c file, but format NV21 is not supported. I hope that the video stream in NV21 format can be directly obtained in the application.
Thanks!
the format from chip bridge is NV21 or you need to convert the input video to NV21?
need to convert the input video to NV21
what is your real capture data? do you need convert raw data to NV12? if yes, you can use software ISP do this,
