(Solved)Cheese doesn't detect lifecam vx-3000

Message

SpiroPoulos89 · Post by **SpiroPoulos89** » Mon Aug 31, 2009 6:30 am

Hello

I have a Microsoft Lifecam vx-3000. With ubuntu using the kernel 2..29 the webcam worked automatically so I know it is supported.

I don't know what to enable in the kernel to make it work on gentoo. I think It uses the v4l driver but I did not see lifecam
and an option in the kernel.

Does anyone know what has to be selected and/or installed to make it work.

Thanks

If you use lsusb, you can maybe get the actual chip that it uses, and compile the driver for that.

SpiroPoulos89 · Post by **SpiroPoulos89** » Tue Sep 01, 2009 2:11 am

Thanks for the reply.

This is my camera from the command lsusb

Code: Select all

Bus 005 Device 003: ID 045e:00f5 Microsoft Corp. LifeCam VX-3000

That doesn't tell me anything except that its a Microsof lifecam VX3000.

Does it mean anything else or does anyone else know how to make it work.

Thanks

I am using kernel 2.6.30-r5

On Ubuntu when I installed the kernel 2.6.29 from a .deb file my Microsoft lifecam worked automatically. So I'm sure I just need to enable something in the kernel to make it work for Gentoo.

I don't really like supporting Microsoft but that's the only cam I have, So can someone please help?

Thanks

Somebody must know how. Am I the only Gentoo user with a Microsoft Lifecam?

Give a shout out if you can't get Microsoft Lifecam support in Gentoo.

I don't have that camera, but if you just paste 045e:00f5 in google you will found that you need sonixj module, I think it is gspca_sonixj so enable that in kernel, load module, see dmesg and verify that you have /dev/video0 or video1 etc. if you have other devices like tv card for example...

Thanks for helping but now I can't find sonixj in the kernel. So what I did was enabled all the v4l device drivers including gspca devices and recompiled.

Now when I open cheese the camera's light flashes on then off and shows up as /dev/video0. That's better than before but it's still not working.

Something wrong with enabling all v4l devices?? Anyone know??

Thanks

I tried to emerge gspcav1 but it fails to compile.

When I type in terminal:

Code: Select all

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so cheese

The cam loads but I get a green screen. So it is responding but still not working.

When I was using Ubuntu my cam gave a green screen in cheese without typing in the above command. And in Ubuntu after installing kernel 2.6.29 the cam worked as should.

Here on Gentoo I'm using kernel 2.6.31 now.

So is there any way to make the webcam work properly without the green screen and without the LD_PRELOAD command like in ubuntu??

Thanks for any help

First remove gspcav1, that was needed before, now gspca drivers are in kernel, don't know how you managed to compile it at all, also it would help if you paste last lines from dmesg when you load module or plugin your cam, with lsmod you can see what module is used. Can you try your webcam with some other program, mplayer for example, don't know if libv4l is still needed, cheese use gstreamer so if you have the latest version maybe you don't need it, I saw long time ago a patch for this so upstream maybe took care of this. Remove unused modules from kernel, I don't think this is problem, but I had a cam for which I could load two different modules and with both there was /dev/video0 but only one was right.

edit: now I see that you didn't compiled gspcav1, that is ok

M

Here is the end of the dmesg command after plugging in the cam:

Code: Select all

usb 5-2: new full speed USB device using uhci_hcd and address 3
usb 5-2: configuration #1 chosen from 1 choice
Linux video capture interface: v2.00
gspca: main v2.6.0 registered

gspca: probing 045e:00f5
usbcore: registered new interface driver sonixj

That's a lot of info about my cam. Hopefully this helps.

Also I have libv4l installed but it did not make any difference.

Thanks

SpiroPoulos89 · Post by **SpiroPoulos89** » Thu Sep 24, 2009 11:34 pm

OK......I removed the unnecessary video modules from the kernel and only enabled the sonix modules.

The cam is still responding but it only shows a green screen.

I did not test it with vlc or mplayer but I did test it with cinelerra and it shows a green screen too.

Does anyone know how to solve this.

As I mentioned before, in ubuntu the green screen problem was solved with the kernel upgrade. Kernel 2.6.29 and higher now have the driver built into the kernel.

I'm using the latest kernel (2.6.31) and I believe I enabled the right driver modules in the kernel.

So does anyone know why I am getting a green screen and how I can fix it??

Thank You

Anybody??

ECHO ECHo ECho Echo echo

Guess I ran into a problem here.

I know its possible because as I said It worked perfectly with Ubuntu.

Why not for gentoo??

Any help please.

Thank You

Hi, can you try with mplayer
mplayer tv:// -tv driver=v4l2:device=/dev/video0
and post output, it may be useful, for cheese and other apps that use gstreamer, check gstreamer-properties, there you can set default input and test your cam. If it works there it should work in all apps that use it. If mplayer says unknown pixel format then you should use libv4l preload, also try to preload v4l2convert.so. If you don't have v4l use flag enabled for cheese try enable it.

It showed a screen with different colors.......all red then blue then green and so on.

I have the v4l use flag for cheese.

Both of the following commands still give a green screen:

Anyone know what else is needed to get Microsoft Lifecam working in Gentoo??

Post by **NeddySeagoon** » Fri Oct 09, 2009 5:53 pm

SpiroPoulos89,

This page tells how to set up your kernel and it looks like you have done that. Webcams that produce jpeg output are rare but becoming more common. The tend to work with very few video applications.

Google suggests that xawtv works so you may want to try that

Code: Select all

modinfo gspca_sonixj

may also show some module parameters you can pass the module when you load it.
This means it needs to be made as a <M> not built into <*> the kernel

SpiroPoulos89 · Post by **SpiroPoulos89** » Sun Oct 11, 2009 7:31 pm

Thanks for the reply

Sonix jpeg is compiled as a module and when I type modprobe gspca_sonixj It shows no error but still does not work. I still get a green screen.

I know it has the ability to work normally with cheese because in Ubuntu Jaunty I had it working perfectly, so there has to be some way.

Does anyone know how to make it work in gentoo??

Thank You

SpiroPoulos89,

Code: Select all

modinfo gspca_sonixj

not modprobe.

It will show you the options you can pass to the module at module load tiem.
Then you can try them out with

Code: Select all

modprobe -r gspca_sonixj
modprobe gspca_sonixj option=value

depends:        gspca_main,usbcore
vermagic:       2.6.31-gentoo-r2 SMP mod_unload modversions

I don't see any kind of option/value to load the module with.

Am I missing something?

Thank You

SpiroPoulos89,

Unfortunately not. Thats a list of supported cameras, other modules the module depends on and the version magic

Code: Select all

vermagic:       2.6.31-gentoo-r2 SMP mod_unload modversions

which is used to prevent the module loading with incompatible kernels.

There is one straw to grab at. Not all modules are SMP safe. you could try making a kernel with the SMP option off.
It may be a performance killer if you have a multi CPU/core box as only one CPU/core will be used.
If you only have a single CPU/core, your kernel will get smaller and there will be no bad effects, since you can't use SMP anyway.

You must start the build process with

Code: Select all

make clean

as all of the kernel code will be changed to remove SMP support.

I do have a multi cpu (Duo CPU) and I definately want to keep both cores functioning.

Hopefully smp support is not the problem because it would suck if I had to use only one core when I have two.

In Ubuntu I had the same problem And it was resolved with a kernel upgrade. I don't think the newer kernel was missing smp because I did not notice any performance decrease.

Can you think of anything else that may be the problem?

Thank You

SpiroPoulos89,

Try the same ubuntu kernel where it worked under Gentoo.
If you can reproduce that we can compare the ubuntu kernel setup and the ubuntu driver with the Gentoo ones.

Ubuntu may have some patches that Gentoo does not.

I originally upgraded Ubuntu to kernel-2.6.29 but then found .deb packages for 2.6.30 and 2.6.31. I used them all with Ubuntu and they all worked with the Microsoft lifecam.

So maybe we can compare Ubuntu's .deb kernels to the current Gentoo kernel. In Gentoo I'm now using kernel 2.6.31-gentoo-r3.

Maybe I can run Ubuntu In a virtual machine and test the same kernel version for Ubuntu with my lifecam and we can compare the different kernels like that.

Would that help?

Thank You

SpiroPoulos89,

You can unpick the kernel .deb file and install its parts to Gentoo, then boot it and attach you Gentoo root file system.
There may be a few issues along the way.

Code: Select all

emerge app-arch/deb2targz

and run it on the kernel deb file. It will create a targz which you can unpack with tar in the normal way and do with the contents as you like.
