Thanks for the reply. I updated to the latest v4l-utils, basic tests pass, but I have issues with the streaming tests (-s). I'll work on those, it might take a while. For the reference, here's the actual output, for both the encoder & decoder. root@imx8qxpmek:/unit_tests/JPEG# ./v4l2-compliance -d /dev/video1 -s v4l2-compliance SHA:
