Dear all,
guvcview does not display the extra controls (focus, led etc)
any more since kernel 3.2 an higher (Fedora 16, x86_64).
after the various video modes it says:
vid:046d
pid:0990
driver:uvcvideo
Adding control for Pan (relative)
UVCIOC_CTRL_ADD - Error: Inappropriate ioctl for device

Please can someone shed a little light on this?
Greatly appreciated,
Karl

Karl Hi,
I'm using a 3.2 kernel and I haven't notice this problem, can you
check the exact version that causes it.

Hi Paulo,
I am running plain Fedora 16 on x86_64.
The last kernel where UVC dyncontrols worked was 3.1.10-2.
(If I remember correctly...) The first kernel with failing
dyncontrols was 3.2.1-1 and all later kernels up to 3.3.2-6
fail as well.
libwebcam version is libwebcam-0.2.0-4.20100322svn and
karl,
I've run some tests under ubuntu 12.04 with kernel 3.2.0 and
everything seems to be working fine.
I know some changes were made to the uvcvideo module regarding XU
controls, but I was under the impression that they wouldn't break
userspace.

Hi,
yes, libwebcam depends on uvcvideo.h, I've only added this as a patch
since it was missing from debian kernel headers at the time. I think
you should be able to get it from there now, not sure if the new
header breaks anything, I'll have to run some tests.
The other patches are not needed, but
OK, so UVCIOC_CTRL_ADD is no longer available, now we have:
UVCIOC_CTRL_MAP and UVCIOC_CTRL_QUERY, so I guess some changes are
needed, I'll try to fix this ASAP.

Paulo

Karl Hi,
I'm setting up a libwebcam git repo in sourceforge, Martin Rubli from
logitech (the libwebcam developer), was kind enough to post me all
it's code and the old svn repo backup.
He had already done some fixes regarding the new ioctls for version
0.3, so I just need to go through that and add
Hi Paulo,
I've also done some work on libwebcam a while ago, but have not yet had
the time to send this to Martin Rubli. Attached are git format-patch
patches against the 0.2.1 branch of svn. Note these are against what
was in that branch when I did this work some months ago, so not sure
if it wi
p.s.
Some of my commit messages talk about them needing some
kernel changes / fixes. These are all long in place now
(since before the uvcvideo.h header become an official
userspace available kernel header).

Hans,
I've add you has a developer to the project, so you should be able to
commit these patches yourself,
I would suggest that you pushed a new branch with your changes and
after testing we merge them into the master.
I'm doing the same for some fixes I have planned and also for the code
