    Default Webcamera failure

    Hello all!

    I have a Philips SPC 700NC web-camera which worked alright on OS 11.2. I have recently upgraded (re-installed) to OS 11.4 and I can't have it working anymore. Neither wxCam, Kopete, WebKam, KDenlive, Cheese, Linphone or luvcview is able to use it.

    Here is some output from Konsole:

    Take a look at this thread where I tried to help a fedora user, but quickly learned they knew more than I about this: Philips PWC kernel webcam driver not working correctly - FedoraForum.org

    In their case, it appears the driver with newer kernels can cause problems with this webcam (they could only get it working with a lower resolution).

    Frankly, unless you are an amateur astronomer (where some Phillips webcams are known for being excellent hardware to support such users) I recommend you dump that webcam (give it away to an MS-Windows user ) and purchase your self an inexpensive UVC compatible webcam. While I use the rather expensive Logitech 910 which is UVC compatible (and works with openSUSE-11.3 and 11.4), I gave my sister the Logitech 210 which is also UVC compatible and should work fine with openSUSE-11.4 Linux.

    Thanks for the tip!
    I am no amateur astronomer and the camera was in fact a bit poor on OS 11.2 as well. It did work, but it was a bit slow. Are you happy with your C910? I could perhaps consider buying one of those.

    The C910 is nice, but it does require a relatively new computer with a fair amount of CPU, as the C910 is an HD webcam. The pix it streams on the web are an incredibly high quality, part of the reason being it has an 'auto-focus' capability. The C210, on the otherhand, is not as demanding on CPU capabilities, but is still fairly good in pix quality. And since it is UVC compatible it works well with all apps.

    We can still investigate your Phillips if you want. If the Phillips driver has deteriorated on openSUSE-11.4, I would like to know, so I can make future plans for my mother's PC's openSUSE updates (she has openSUSE-11.3 with her Phillips).

    I'm currently on vacation with very limited Internet access so it won't be until late Monday next week that I obtain the time to support this investigation further. Possibly someone else could chime in, in the mean time. The Fedora thread I quoted should provide a good indication of the things you can check (such as the dmesg , various logs, installed apps, their version numbers, etc ... ).

    Ok, we could make some effort into it if you like. I'll read the post a bit more closely and see where I end.

    Actually, I don't think that your mother's webcam would be affected with the same problem as mine is. It appears that I use some Sonix V4L version2 driver(gspca): http://mxhaard.free.fr/spca5xx.html

    From boot.msg:
    Code:
    <6>[    5.928481] Linux video capture interface: v2.00
    <6>[    5.937465] gspca: v2.10.0 registered
    <6>[    5.940842] gspca: probing 0471:0328
    <6>[    5.944911] sonixj: Sonix chip id: 11
    <6>[    5.964911] sonixj: Unknown sensor 0000 - forced to mi0360
    <6>[    5.966973] input: sonixj as /devices/pci0000:00/0000:00:1a.0/usb4/4-1/input/input8
    <6>[    5.967113] gspca: video0 created
    <6>[    5.967150] usbcore: registered new interface driver sonixj
    PS
    I am quite new to 11.4 and in Yast I could not find the log viewer, isn't there a module for this anymore?

    Good point. The gspca is included in the kernel. Take a note of this webpage: HCL:Web cameras - openSUSE

    Some applications still don't work very well together with the gspca drivers, a workaround is to preload a libv4l-compat library:
    Code:
    LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so <application>
    before starting the respective application, i.e. for kopete you would type:
    Code:
     LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so kopete
    This compat-library can be found in the package "libv4l", which is available from OSS-Repo or (recommended) from Packman. (see - Additional YaST Package Repositories)

    If you have a 64 bit system, you preload the library with:
    Code:
     LD_PRELOAD=/usr/lib64/libv4l/v4l1compat.so <application>
    If you want to run a 32 bit application (i.e. skype) on a 64 bit system, you first need to install "libv4l-32bit" (only available in the Packman repository) and run the preload-command used for 32 bit.

    If this works for you, you can add the LD_PRELOAD-command to the startup command of your menu entry/desktop shortcut via menu editor or with right-clicking the desktop icon => properties => application => command respectively.

    You can use ksystemlog as log viewer.

    Thanks! Yes I suppose I can use that one, I had just grown accustomed to the yast module

    I think it was considered obsolete since there are other tools provided by
    the desktop environments.
