 Posted: Wed Nov 19, 2008 3:12 pm Post subject: luvcview won't run |
 |
|
I'm trying to run luvcview on my Dell Inspiron 1720. I have omnivision and v4l support compiled into the kernel, and xf86-video-v4l and libv4l emerged. I get this:
| Code: |
audiodef@localhost ~ $ LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so luvcview
luvcview version 0.2.1
Video driver: x11
A window manager is available
video /dev/video0
ERROR opening V4L interface
: No such file or directory
|
I'm thinking I need to tell luvcview to use the v4l video driver, but how (and am I right)?

It seems to be recognized by the system, but not by user software.

what version of linux-uvc and luvcview do you have?
| Code: | ts ts # luvcview
[b]luvcview 0.2.4[/b]
SDL information:
Video driver: x11
A window manager is available
Device information:
Device path: /dev/video0
Stream settings:
Frame format: MJPG
Frame size: 640x480
Frame rate: 30 fps
Quit signal received.
Cleanup done. Exiting ... |
later edit: i realise now that i am using luvcview and linux-uvc from svn. maybe you should give it a shot? |

I think once this is solved, I'll be able to use the webcam in skype, kopete, and other programs. Those programs are currently showing "no video device", even though luvcview finds it as root. |
add yourself to 'video' group |
