I applied all your suggestions, and some extra simplification; now I'm
running v4l2-compliance but I have this error:
Allow for multiple opens:
test second video open: OK
test VIDIOC_QUERYCAP: OK
fail: v4l2-compliance.cpp(322): doioctl(node,
VIDIOC_G_PRIORITY, &prio)
test VIDIOC_G/S_PRIORITY: FAIL
which I don't undestand. I don't have vidio_{g|s}_priority functions in
my implementation. And I'm using the V4L2_FL_USE_FH_PRIO flag as
suggested in the documentation:
---------------
- flags: optional. Set to V4L2_FL_USE_FH_PRIO if you want to let the
framework handle the VIDIOC_G/S_PRIORITY ioctls. This requires that you
use struct v4l2_fh. Eventually this flag will disappear once all drivers
use the core priority handling. But for now it has to be set explicitly.
