Cheese & other V4L-1 applications do not work with OmniVision webcams 05a9:7670 and 05a9:2640

[b3n87]

Binary package hint: cheese

I have a Dell M1330 - Ive tested the web cam with Ekiga and it works fine. When I launched Cheese it doesnt show the webcam preview, and when you press "Take a photo" the screen goes white after the count down, then it crashes.

This is on Ubuntu 8.10

Please attach the output of "lsusb"

I have the same problem with the same laptop, but I think it's not related to Cheese, because it affects also skype. So I think it's a driver problem.

[Mackenzie Morgan (maco.m)]

Ah, just found something else to check...
Does it work with Camorama? That apparently uses V4L 1, while Ekiga uses V4L 2. Maybe Cheese has issues with V4L 1.

[vinlos (vincenzo-losito)]

It doesn't work with Camorama too.

This is my lsusb output:

Oh, two different models of webcam on the same model of laptop exhibiting the same broken behaviour. Lovely.

b3n87:
Can you test Camorama as well just to be certain you two are experiencing the exact same bug?

Can you both try running Ekiga from the command line as well? Post any errors you receive.

[b3n87 (benhellyer)]

Hi guys,

I tired Camorama and it just displaced an error saying:

"Could not connect to video device (/dev/video0).
Please check connection."

I ran camorama from the terminal the the -D option for debug messages, I attached the output as an attachment.

[b3n87 (benhellyer)]

Sorry, forgot to say, cheese silenced out, and there are no debug options that can be ran from the terminal.

[vinlos (vincenzo-losito)]

I can confirm the bug is related to cheese, because even if my webcam didn't work with other application (such as skype), giving the following commands:

$modprobe -r uvcvideo
$modprobe uvcvideo

the webcam come back to work in Skype. In addition, if I try to run Cheese again, the webcam stops working in every application, so it's necessary to do again the previous commands.

I hope it could be useful for the developers.

This looks like a dulicate of bug #290506. Can you try changing the resolution as described there?

[b3n87 (benhellyer)]

Ive tried changing the resolution, and that just crashed Cheese.

Why is it that it no longer works? In Hardy you had to compile and install this driver:

Hi everyone, I found out a work around.

You need to suspend the laptop/PC, then wake it up again and it will work, when i was at college and woke up my Dell M1330 I noticed an error:

Marking this bug as a duplicate of bug 290506, I know at least two people with the very same hardware that managed to fix the issue installing Stefan Bader kernel package listed in that bug or manually compiling latest uvcvideo.
