webcam problems

Post by heviejob »

Hi. I have an issue with my webcam too its a lightwave LW-IC500 its seems the module and driver are loading properly but the cam freezes or has bad quality. Its produces dark images which have unreal colors. It has a lot of green shade. Changing the resolution is not possible.

output from lsusb gives

Bus 002 Device 002: ID 15d9:0a33

lsmod | grep spca
gspca_sonixj 24064 0

The webcam used to work in Linux mint 5, grant it not a quality picture but at least worked, i can only get it to work with PCLinux both KDE and Gnome.

I don't know why it's not working with LM7 and 5, i also have a Logitech quickcam express that won't work with any linux distro.

Please don't just add randomly to a post about webcams - this is a different problem than in the topic you originally added this to

Suggestions for tackling 0c45:6143 webcam issues

Post by pdc_2 »

If you go here

http://mxhaard.free.fr/spca5xx.html

it is a list of gspca supported webcams; if you search on the vendor/product ID, your camera does not appear in the list; that is not good;

nor does it appear on this list of UVC supported devices;

http://linux-uvc.berlios.de/#devices

that also would be perceived by many to be not good;

However if you google search on the vendor/product ID of your device
linux configure 0c45:6143
you get such results as this

http://kerneltrap.org/mailarchive/git-c ... /8/2858764

and translated, this seems to mean that the guy in the top post that was quoted above (http://mxhaard.free.fr/spca5xx.html)

seemed to have produced fixes for your camera; see also

http://www.mail-archive.com/linuxtv-com ... 00767.html

So: your camera: what about use the above two posts and join the specialist forum; and email Jean-Francois Moine;

if you subscribe briefly to an expert forum (such as webcam drivers); (as I have done on occasions), you will get the answer and can then politely retire;

more suggestions

looking around other linux distros; and what they recommend:

on OpenSuse they say that
The gspca-drivers were added to the mainline linux-kernel in 2.6.27, so openSUSE 11.1 already contains drivers for most gspca-devices.
http://en.opensuse.org/HCL/Web_Cameras

they say
However, some applications still don't work very well together with the new drivers, a workaround is to preload a libv4l-compat library:

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so <application>

before starting the respective application, i.e. for kopete you would type:

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so kopete
I see libv4l is already loaded in Mint:

here was someone getting a webcam to work

http://forums.opensuse.org/hardware/414 ... rking.html

and if you jump to post #7 here

http://forums.opensuse.org/hardware/414 ... 000-a.html

Axel explains about how the gspca was installed into the latest kernel, and some of the teething problems that brought: but he suggest workarounds

This compat-library can be found in the package "libv4l"

sorry to hear that your webcam is still not working;

there is an opinion that UVC webcams work out of the box now:

http://linux-uvc.berlios.de/#devices

this is a list: Plan B may be you just have to invest in a new webcam: (or a second-hand from a online site?)

even if said to work out of the box, if buying from shop, surely best to try to plug into your distro before purchase;

the gspca drivers were built into the 2.6.27 kernel but many seem to paradoxically report that webcams that .. worked in older versions of distros, no longer work ...

........ some have suggesting installing the latest gspca drivers (for seemingly gspca webcams)

http://linuxtv.org/hg/v4l-dvb

but again, that is not a panacea
