@everybody: Please also note that libv4l 0.5.6 has got a nasty bug that prevents uvcvideo webcams to correctly work. So the kernel alone is not enough to make Cheese work again. The new libv4l 0.5.7, with the fix, already went through a SRU and should enter intrepid-proposed soon (if it didn't yet) (see bug #308890).

I talked about this issue with the uvcvideo maintainer. It seems it is strictly connected with gstreamer's v4l2src switch to libv4l2. Anyway he came up with a patch that fixes it, or at least fixes mine. He will commit it to his branch on linuxtv.org soon, I'll keep you updated. -- cheese malfunctioning with UVCVIDEO webcams (was cheese doesn't show v4l2 video output and disables output on gstreamer-based apps ran afterwards) https://bugs.launchpad.net/bugs/290506 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gstreamer0.10 in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

zoomy, see the big fat warning printed when you run make? svn repository is deprecated. If you want to give some help you should really try the mercurial repository I pointed you a couple of hours ago (http://linuxtv.org/hg/~pinchartl/uvcvideo). Anyway notice that it contains the whole v4l-dvb stack and I wouldn't suggest to a newcomer to compile it. If you still want help trying the patch do it in a test environment, you just have to run hg clone http://linuxtv.org/hg/~pinchartl/uvcvideo, make, sudo make install. Probably it will install the driver on a different place than the ubuntu one and you will have to manually remove the latter. If you cannot manage to compile it or you experience any error please ask for help on irc or ubuntuforums. This bug is already overloaded, if we want it to be solved I'd suggest to add here only comments that can be useful for a solution. So, again, could you guys give a try to the updated driver in Laurent's branch? -- cheese malfunctioning with UVCVIDEO webcams (was cheese doesn't show v4l2 video output and disables output on gstreamer-based apps ran afterwards) https://bugs.launchpad.net/bugs/290506 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gstreamer0.10 in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 290506] Re: cheese doesn't show v4l2 video output and disables output on gstreamer-based apps ran afterwards
Francisco, as I said previously (not sure if it was here), I'm not upset with you or with anyone at all. It's just that lately I hear so many people complaining that cheese doesn't work, I even read some rather expert guy in the forums saying to newbies things like cheese is completely broken in intrepid. Cheese is just a software that gives you the webcam images, but there is some sort of toolchain to make it work: we use gstreamer, gstreamer uses the video4linux api to access the device, the video4linux api interacts with your particular webcam driver. So if something is broken in this chain users always see Cheese as broken and report us it doesn't work. But there is some great chance that cheese is not failing but something at a lower level is. Since most of the late issues appeared with intrepid switching to 2.27 kernel and many development went on recently in webcam drivers the chance of some regression at kernel level is someway increased. I'm still not sure if gstreamer is involved too, but it seems it's really an uvcvideo specific issue, so, maybe, they could be both related. Perhaps, just perhaps, it is a different issue? I don't think so, maybe there are different ways to reproduce it but all end up with the webcam locked in the same way. I have to tell you that I have yet to succeed locking my camera using gstreamer. As I mentioned above, there seems to be quite a number of people in this list able to use gstreamer and who are unable to use cheese. It would be nice if you would reckon that these reports were also made. Did you try all the different resolutions supported by your webcam with gst-launch? There is an easy way to get a better idea about who's causing the bug: Could any of you test cheese with a 2.26 kernel? FWIW, considering your email address, I have to assume you are a Gnome dev, and thus Cheese developer. If you are, I would like to thank you for working on Cheese. It is a lovely application, and I was delighted when I found it. Yes, I'm a Cheese developer, thank you :). Again, I'm sorry if I appeared upset (consider also that English is not my motherlanguage :P). -- cheese doesn't show v4l2 video output and disables output on gstreamer-based apps ran afterwards https://bugs.launchpad.net/bugs/290506 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gstreamer0.10 in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 290506] Re: cheese doesn't show v4l2 video output and disables output on gstreamer-based apps ran afterwards
It may be the case that Cheese makes correct use of the API, in a way most other applications don't use the API, and that uvcvideo breaks when used this way. The API? which api are you talking about? the v4l2 api? we just do *one* ioctl, it's a very basic and simple one and it's already been verified it's not the guilty one. Anyway cheese works with every other webcam driver out there and doesn't have this issue with prior versions of uvcvideo. Is it that hard to understand that something there has changed and it's causing this bug? I can reproduce the very same bug with gstreamer alone, so it's clearly not a cheese issue. Others reported the bug with gstreamer alone too. I don't know how Kopete works but I cannot see anyone here who said the issue doesn't stand with it. Regarding skype, please stop enumerating it.. it's closed source, how could be useful to know it works? Does it use v4l1 api? does it use libv4l? what resolution does it set? -- cheese doesn't show v4l2 video output and disables output on gstreamer-based apps ran afterwards https://bugs.launchpad.net/bugs/290506 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gstreamer0.10 in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

Could any of you check if the issue can be reproduced with pre 2.27 kernels too? The last one from 2.26 series should be fine. I want to be 100% sure this thing has nothing to do with cheese (and possibly with gstreamer too) and it is a uvcvideo issue only. -- cheese doesn't show v4l2 video output and disables output on gstreamer-based apps ran afterwards https://bugs.launchpad.net/bugs/290506 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gstreamer0.10 in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 290506] Re: cheese doesn't show v4l2 video output and disables output on gstreamer-based apps ran afterwards
zoomy942, the relevant part of that thread (the one about uvcvideo driver) suggests to install latest trunk from uvcvideo svn. That's the latest version before uvcvideo was included in mainline kernel (2.27) and probably the same (or almost the same) one included in Hardy. If it fixes the issue it's just one more evidence that Cheese is not involved at all with this thing and it is a driver/kernel fault only. There were many changes in webcam drivers with 2.27 kernels, it is likely that some regression went in too. -- cheese doesn't show v4l2 video output and disables output on gstreamer-based apps ran afterwards https://bugs.launchpad.net/bugs/290506 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gstreamer0.10 in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

[Bug 290506] Re: cheese doesn't show v4l2 video output and disables output on gstreamer-based apps ran afterwards
Andres, as I said in bugzilla I was wrong about libv4l.. I don't know what made me believe that patch fixed the issue (it was late and I was really tired) but, unfortunately, it doesn't. Also please forgive me if I appeared rude with you, I didn't want it, it's just that lately too much people says cheese doesn't work with intrepid but it's just that many changes went in webcam drivers with 2.27 so some regression went in too and we have no power on it. Anyway it seems like it's not a cheese issue at all. I have the issue and can reproduce it only if I use the webcam at maximum resolution both with cheese and gst-launch. gst-launch-0.10 v4l2src ! video/x-raw-yuv, width=640, height=480 ! xvimagesink Works perfectly, it can be run many times with no issue. gst-launch-0.10 v4l2src ! video/x-raw-yuv, width=1280, height=1024 ! xvimagesink Locks and the webcam doesn't work anymore without reloading uvcvideo. Could any of you confirm this? I'm going to report it to the uvcvideo developer. -- cheese doesn't show v4l2 video output and disables output on gstreamer-based apps ran afterwards https://bugs.launchpad.net/bugs/290506 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gstreamer0.10 in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 290506] Re: cheese doesn't show v4l2 video output and disables output on gstreamer-based apps ran afterwards
Andres, cheese asking hal for v4l capable devices has absolutely no relation with this bug. Please don't blame us if you don't know what you are talking about. We just use gstreamer to access the webcam device. The only thing we do on our own (directly accessing the device) is a VIDIOC_QUERYCAP ioctl to see if the webcam is a v4l2 or a v4l one. I really doubt that could cause such a behavior and if so that would be still an uvcvideo issue. Anyway why don't you guys report bugs to the proper place?
