I'm trying to troubleshoot issues with capturing and displaying video on an i.MX6 Sabre board. Video drivers are not my forte.
We're using Yocto to build our bsp and I have added the v4l2-utils packages and dependencies. A result of adding this package is the v4l2-compliance tool. When running that tool, there are several failures. Please see attached. I have read in other posts that claim success despite v4l2-compliance issues.
I also performed an strace on an application that is attempting to access /dev/video0. Please see attached. It is obvious that the driver is not providing some of the necessary functionality, namely VIDIOC_TRY_FMT and VIDIOC_QUERYCTRL.
My question is, do I have a broken driver that needs to be patched or are these failures normal? Has anyone experienced this issue?
