Hi All,
One last thing before I really leave on vacation which just popped
in my mind as something which I had not mentioned yet.
The new ctrl framework also enumerates classes when enumerating
ctrls with the next flag. I wonder if this is intentional?
It's absolutely intentional. It's needed to produce the headers of the
tabs in e.g. qv4l2. It's been part of the spec for several years now.
IOW if this is a feature or a bug?
Either way this confuses various userspace apps, gtk-v4l prints
warnings about an unknown control type,
It should just skip such types.
and v4l2ucp gets a very
messed up UI because of this change. Thus unless there are
really strong reasons to do this, I suggest we skip classes
when enumerating controls.
Those apps should be fixed. If apps see an unknown type, then they should
always just skip such controls (and later add support for it, of course).
Ok, I will fix those apps (for gtk-v4l I'm involved upstream, for v4l2ucp
I'll fix it for Fedora and submit a patch upstream).
Regards,
Hans
