Description Fabiano T 2009-11-03 07:54:38 UTC

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; it; rv:1.9.1.3) Gecko/20090909 SUSE/3.5.3-1.2 Firefox/3.5.3

Webcam problem, notebook ASUS k50in, CN7129 04f2:b071 , flips image upside down; wrong brightness, resolution and color tuning.
I have first updated (opensuse update and webcam repository) UVC and libv4l modules and drivers.
UVCvideo r260, libv4l 0.6.1
luvcview correctly visualize colors and resolution (tune brightness automatically) but the image is flipped upside down.
I have try updating with opensuse build packages libv4l to 0.6.2.
Nothing has changed.

The big problem is with Skype, image is totally wrong, flipped upside down at very low resolution, very dark with a green background tone.
I am able to flip the imag right with this workaround:
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype

but the image is still unusable, wrong colors.
Please update UVCvideo to the very last releases and update libv4l too.
Skype is a fundamental piece of software please fix this incompatibility.

Looks like a dupe of Bug 501959

try:

Users affected by this bug in 11.1 are encouraged to install libv4l and either
run their applications like this:

LD_PRELOAD=/usr/lib64/libv4l/v4l1compat.so kopete
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so skype     # 32-bit applications

Slightly less recommended is to add the following to /etc/ld.so.preload:
 /usr/lib64/libv4l/v4l1compat.so
