Dell XPS 15 Built-In Webcam: cheese does not display any image

[Daniel Kessel]

Cheese does not display any image. Image manipulation buttons are disabled, too.

This is a regression. It worked on every release since Precise.

By the way.. the debug mode did not work. Cheese did not start. See HookError_source_cheese.txt

[Daniel Kessel (dkessel)]

The camera device is detected just fine, it seems:

dmesg output:
[ 2.282910] usb 1-1.4: New USB device found, idVendor=0408, idProduct=2fb1
[ 2.282921] usb 1-1.4: New USB device strings: Mfr=3, Product=2, SerialNumber=0

[ 2.282940] usb 1-1.4: Manufacturer: CN07CN2C786641CU230DA00

Status changed to 'Confirmed' because the bug affects multiple users.

[Rocko (rockorequin)]

Same here (Dell XPS 15 L502x). Cheese's preferences window shows that it has detected the camera device, but nothing works and there are no error messages in the terminal.

Video capture works fine in vlc.

Hi all the same problem, I made a fresh install on a Dell xps-l502x:
Dont works with VLC, Cheese and GTK UVC

Hope you guys can help me with this problem.

GTK UVC (guvcview) doesn't work? I've got version 1.7.1-1ubuntu1 and it works on my xps-l502x. Skype also works, but cheese still doesn't.

@andres: on my L502x laptop, guvcview does recognise the camera - the output shows something like this:

...
jack server is not running or cannot be started
video device: /dev/video0
Init. Laptop_Integrated_Webcam_2HDM (location: usb-0000:00:1a.0-1.4)
{ pixelformat = 'YUYV', description = 'YUV 4:2:2 (YUYV)' }
... lots of information about formats is displayed here...
vid:0408
pid:2fb1
driver:uvcvideo
checking format: 1448695129
fps is set to 1/30
drawing controls
...

Whether it works definitely is kernel-dependent, though. It works just with 3.15.7 (there are a couple of 'resource temporarily unavailable messages at the start, then it works), but 3.16-rc7 keeps compaining about the device being unavailable or the buffer being empty and I just get a black screen, even though the white LED comes on to show the camera is being used. The stock 3.13 kernel works for me (at least it did when I tried it in a VirtualBox VM: it missed a lot of frames but did display a picture). Even thought guvcview doesn't work with kernel 3.16, motion and Skype both do. Odd.

Cheese still doesn't work with any kernel, which is disappointing.

@Rocko As you say In my case it seem to be a kernell problem, what do you recomend me ?

Attached the lsusb and kernel information, the webcam stills down. (:/)

[Sergio Torres (sergiotca)]

So is there any advance on this issue?

I'm still having this problem on 14.04.

Both cheese and skype show black screens but I it you go to a site like http://www.testmycam.net/ the camera works as expected.

???

Can I provide any further data for analysis?
