Re: logitech quickcam 9000 uvcdynctrl broken since kernel 3.2 - PING
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 will still apply cleanly.
I would really like to work together with you on getting an updated version
of libwebcam out there for use in distros (I maintain libwebcam in Fedora,
and AFAIK you maintain it in Debian, right?)
My sourceforge.net account is jwrdegoede, I hope you're willing to give
me commit access to the git repo there.
I guess if there is going to be more then 1 of us working on the git repo
we should have some review procedure. If others don't object we could post
patches to linux-media, prefixing the subject with a [PATCH libwebcam] and
then do reviews on linux-media and push only after an ack?
I guess we could start with that right away with my proposed patches,
if you can make an initial git repo available I can rebase on top
of that and then send the patches with git send-email (so 1 patch / mail)
for review?
Either way thanks for working on this!
Regards,
Hans

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 add them to 0.2.
I still need to check with him how he wants to handle the 0.3 version,
since it has a lot of new code ( and some extra apps ).

looking better now.
So far I have got a focus slider and a LED1 frequency slider,

Re: logitech quickcam 9000 uvcdynctrl broken since kernel 3.2 - PING
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 for version 0.3 that Martin kindly send me (it has a lot of new apps, including a qt interface, and video capture support). This is the project page: https://sourceforge.net/p/libwebcam/code currently master is not building against the new uvcvideo.h, I'll try to fix that today, also the check for this header during configuration is unnecessary since it's now in linux headers (just need to include it with linux/uvcvideo.h) Regards, Paulo 2012/5/4 Hans de Goede hdego...@redhat.com: 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.

Re: logitech quickcam 9000 uvcdynctrl broken since kernel 3.2 - PING
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 they do increase functionality to some extent. Anyway if this was just a libwebcam issue, guvcview should still be able to add the controls, and apparently that's failing also.
