Hi, you are not giving any details.. what happens when you start cheese? do you get the no camera message? How do you know that it's uvc? does it works with other software?

cheese -v output would be highly appreciated.
lsusb can help too.
Other random infos not stricly needed could be modinfo uvcvideo, uname -r etc, relevant dmesg part (attach it if you don't want to strip out unneeded messages).

Hi again, I did a quick search and it seems that the webcam in your laptop is a Microdia one, does lsusb have a line like "0c45:62c0 Microdia"?
If so I have exactly the same device and it works pretty well..

Cheese looks like that

I'm sorry Filippo, this is my first bug submition. Here we go:

-- what happens --

When I start Cheese all I can see is a pattern of rectangular shapes in different colours, and in the lower right corner there's a little square where it seems the program would like to output the video, but it's a gray-and-white snow. [see attachment]

I get no message boxes.

It's UVC because gstreamer says so (Default Input: Device -> HP Pavilion Webcam (UVC) #1"

-- other software --

Yes, it works with skype (and ekiga, but I don't use it).

-- verbose --

cheese -v command in the console returned nothing, sorry.

-- lsusb --

I'm working on it..

does 

gst-launch v4l2src ! ffmpegcolorspace ! ximagesink 

work for you?

Hi,

Yes it does, although on fullscreen it's little sluggish :) I attach the output, if it's any use:

I'm not sure if it's relevant... I'm not sure even what's uvc (was it a driver? ). I'm installed the r5u870 driver to make my webcam work. But as I mentioned, it doesn't work with cheese.

Ok no need for other info.
So "uvc" doesn't stand for uvcvideo :). Seems that hp ships 2 different webcams (uvcvideo based microdia ones and r5u870 based ricoh devices), good to know for future bug triaging.


There is a known issue with your driver. Please take a look at bug http://bugzilla.gnome.org/show_bug.cgi?id=531835 and follow discussion there.
Marking as duplicate.
