I've got the latest uvcvideo driver module loaded and the camera works fine with Kopete and lucview. In Skype Options->Video Devices I have 'Enable Skype Video' checked and 'UVC Camera (046d:0991)(/dev/video0)' shows as the selected webcam. But when I try to test the video device I get:
Skype V4L2: Could not find a suitable capture format
Skype V4L2: Could not find a suitable capture format
Starting the process...
Xlib: extension "XVideo" missing on display ":0.0".
Skype Xv: Xv port query failed
Skype XShm: XShm support enabled
and a black screen. When I'm connected to someone else we can hear each other just fine, I can see them, but they can't see me. Can someone please help me resolve this V4L2 capture format issue?
thanks...
Full Version: Skype V4L2: Could not find a suitable capture format
I was able to resolve the missing "XVideo" extension by adding
Load "extmod"
to the "Module" section of /etc/X11/xorg.conf. It currently looks like:
But I am still getting a black screen and the following output when trying to test my video device
Skype V4L2: Could not find a suitable capture format

Starting the process...
Skype Xv: Xv ports available: 32
Skype XShm: XShm support enabled
Skype Xv: Using Xv port 224
Skype Xv: No suitable overlay format found
My video card is (from lspci):
01:00.0 VGA compatible controller: nVidia Corporation Quadro FX 360M (rev a1)
I've attahed a copy of /var/log/Xorg.0.log and output from xvinfo.
Any ideas? thanks...

The problem lies in this case with the capturing. Is it possible to bring a v4l-info output for your camera?
v4l-info can be found in the xawtv package.

I have the very same problem here, with a new Logitech Quickcam Pro 9000 (UVC driver). When I try to configure video and test it, the screen stays blank, skype gives me the following output:

Hello,
Same problem with a Hercules Dualpix Express webcam on Skype 2.0.0.72 in Ubuntu Hardy with a Radeon 7000/VE videocard. This webcam is properly working with this same version of Skype in Ubuntu Feisty with a Geforce 6200.
After compile last version of uvcvideo driver and reinstall skype:
Skype V4L2: Could not find.....
Skype Xv: Using Xv port 73
Skype Xv: No suitable overlay format found
This webcam works in this PC with Ekiga, luvcvideo and others
Thanks for your help.

You will find there full description of the bug including a workaround which may work for some of you.
@skype devs:
Please include the LD_PRELOAD hack in your code and prevent linux users from having a painful skype experience requiring CLI fix before getting it working. It's no problem for advanced users but it's killer bug for beginners.
Almost any apps using webcam as been fixed in ubuntu but since skype is closed source you are the only one able to fix this.

I think I have the same problem described by others in this thread:
My webcam (Logitech QuickCam Pro 9000) works fine with Ekiga and on my laptop but not on my desktop PC.
Both boxes used to run Ubuntu Hardy and had no problem with the Skype webcam. Both were recently moved to Ubuntu Intrepid. The laptop ran through the upgrade process, the desktop was rebuilt with a new install of Intrepid.
Since the install of Intrepid the webcam has stopped working with Skype on the desktop, although it is fine with Ekiga. When I start Skype from the command line and run the camera test the little test box shows a black screen and I get the following errors on the command line:
Starting the process...
Skype Xv: Xv ports available: 1
Skype XShm: XShm support enabled
Skype Xv: Using Xv port 56
Skype Xv: No suitable overlay format found
libv4l2: error dequeuing buf: Invalid argument
I have tried using the workaround "LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype" but the error is unchanged.
I have also tried installing Stéphane Marguet's patched version of libv4l (https://bugs.launchpad.net/debian/+bug/260918), again the error is unchanged.
Can anyone suggest anything else I might try to fix or help debug the problem?
Thanks got any help.

hi,
failure found - first I found out that my camera works in Skype after starting it in the terminal with sudo su.
solution:
chmod 777 skype

I moved my Logitech Notebook Pro webcam to a another computer that has USB 2 interfaces and the webcam started working in Skype with a resolution of 1024*576. Unfortunately the picture is very unstable and stops working after a minute or so.
Hopefully this will improve in the next Skype version for Linux.
The previous PC:s I have tried to use this webcam with have only USB 1.1 ports. With a USB 1.1 connection the webcam has only Motion JPEG modes, that are not supported by Skype. Skype so far only supports YUV modes, but hopefully this will be fixed in the next Skype release for Linux.
I checked the modes of my webcam by installing luvcview from
http://mxhaard.free.fr/spca50x/Investigation/uvc/
The modes can be queried with
luvcview -d /dev/video1 -L
luvcview version 0.2.1

I have an analog capture device at /dev/video0 so the webcam becomes /dev/video1.
There are modules for turning MJPG devices on the fly into YUV devices, but I have not tried them.
Hopefully this will improve in the next Skype version for Linux.

I can tell you what the problem is, Ive been thru this MANY times. You have to set gstreamer props for V4L1, not V4L2. Go to your multi media settings>video tab. 1st one is: Auto detect (pipeline will show blank ) The 2cd one is: V4L1 (pipeline will show blank) test both, you will see color bars. Youre good to go. You can always run tests thru "camorama" OR "cheese" both found in synaptic or sudo apt get install camorama... sudo apt get install cheese. Once you install camorama, the cam box that comes up will be blank. Do a right click inside the blank box, and set your prefs> color correction, ect. Good to go. Also, you must reboot for it to pick up the Logitech. I too have that cam, works great. Good luck :-s
Thanks ThomasU. I spent hours trying several different fixes to make my webcam work with Skype. I finally came across your solution and it worked immediately. Thanks!
Thanks from another grateful reader! With this plus the microdia driver, the camera is at last working perfectly on my Thinkpad Z61M.
