Webcam not working

[Dosenpfand]

Hi guys,
i have a problem with my Samsung NC10. I Installed Xubuntu 9.10 and nearly everything worked great except the webcam.
wen i try luvcview to test it i get:

Code: Select all

luvcview 0.2.4

SDL information:
  Video driver: x11
  A window manager is available
Device information:
  Device path:  /dev/video0
Stream settings:
  Frame format: YUYV (MJPG is not supported by device)
  Frame size:   352x288 (requested size 640x480 is not supported by device)
  Frame rate:   5/1 fps (requested frame rate 30 fps is not supported by device)

the webcam window opens but it's all black. also in Skype and cheese it doesn't work.
Can someone help? Thanks in advance!

Just tried 'luvcview' on my NC10, this is the output:

Code: Select all

luvcview 0.2.4

SDL information:
  Video driver: x11
  A window manager is available
Device information:
  Device path:  /dev/video0
Stream settings:
  Frame format: YUYV (MJPG is not supported by device)
  Frame size:   640x480
  Frame rate:   30 fps

and everything works as expected.
Please use these commands to check if the 'uvcvideo' module is loaded with non-default options:

Code: Select all

cat /sys/module/uvcvideo/parameters/quirks
cat /sys/module/uvcvideo/parameters/nodrop
cat /sys/module/uvcvideo/parameters/trace

If the output of the 3 commands is '0', you are using the defaults options (they work for me).
If this is the case, it's likely to be an hardware problem of your webcam.

yes the output of all 3 is 0
seems to be the hardware
thanks for your help!
