Bad Quality Video in UVC class camera Logitech C200

English Multimedia
1

Hi:

I use Logitech C200 UVC class camera, which works with very good quality on windows.

On opensuse 11.2 and also 11.3 factory latest, quality is really bad (recognizable but really bad). Bad quality is the same regardless the app - in Cheese, Kopete, and Skype.

I use the uvcvideo driver, no other (spca or such) is installed.

Any ideas what can be the reason for working but much worst quality?

Thanks - some info below

I found the reason. I did not have v4l2 loaded.

Once I did

modprobe v4l2_common

modprobe uvcvideo

It started working with good quality, looks the same as on the other os.

lsmod | grep v4l

v4l2_common 16765 0
videodev 39454 2 v4l2_common,uvcvideo
v4l1_compat 14913 2 uvcvideo,videodev

lsmod | grep uvc

uvcvideo 62263 0
videodev 39454 2 v4l2_common,uvcvideo
v4l1_compat 14913 2 uvcvideo,videodev
