v4l2-compliance failures

Question asked by Ken Frederickson on Jun 28, 2013
Branched to a new discussion



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?
