Hi Mauro, Is there some instructions on adding new sections in the v4l2 documentation. I had been struggling yesterday to add my documentation for video timing API. It is easy to make minor documentation changes. But since I am adding new ioctls, Looks like I need to create vidioc-<xxx>.xml under DoCBook/v4l/ directory since media-specs/Makefile is generating videodev2.h.xml automatically (I learned it in the hard way). I have added the IOCTL name in media-specs/Makefile and also added the structure name. But somehow, the videodev2.h.xml file doesn't show my structure types documented in vidioc-<xxx>.xml. Any idea what could be wrong? Murali Karicheri Software Design Engineer Texas Instruments Inc.
