Add support for metadata output video nodes, in other words,
V4L2_CAP_META_OUTPUT and V4L2_BUF_TYPE_META_OUTPUT.

Hi all,

This patch adds support for metadata output in v4l2-compliance.

It depends on the metadata output patch:

Please ignore this version for now. This needs to be prepended with a
proper header update in a separate patch.

Hi Sakari,

Thanks for the patch, but it is not complete. Most importantly the V4L2_BUF_TYPE_LAST
define in v4l2-compliance.h isn't updated to V4L2_BUF_TYPE_META_OUTPUT.

It's best to just do a 'git grep META_CAPTURE' in v4l-utils and check each place it
is used whether META_OUTPUT support should also be added.

Note for v4l2-ctl-meta.cpp: interestingly the usage help for meta formats already
includes support for meta output, but no where else in v4l2-ctl is there meta output
support.

It appears to be unintentional that this was committed.

Regards,

	Hans

That's what I did but I somehow missed META_OUTPUT in v4l2-compliance.h. 
I'll update the set, but I don't expect this to be merged until the 
kernel support for metadata output goes in with Yong's ipu3 patchset.

Seems so. This set is (so far) only adding support for v4l2-compliance.
