LUVCVIEW
luvcview version 0.2.1
Video driver: fbcon
Hardware surfaces are available (5120K video memory)
video /dev/video0
ERROR opening V4L interface
: No such file or directory
I had this working fine in 11.1, but not 11.2
Any ideas?
The webcam that I used to compile the driver in 11.1 to work, “just work” in 11.2.
Here is my output
luvcview
luvcview version 0.2.1
Video driver: x11
A window manager is available
video /dev/video0
format asked unavailable get width 800 height 600
Did you try another application for testing your webcam.
In 11.1 I cannot make luvcview work and in gqcam using the workaround “env LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so gqcam” it works.

the problem is, the device is never initialized properly. There is no
/dev/video or /dev/video0
I have pretty much exactly the same problem of no /dev/video or /dev/video0
Only difference is I am still on 11.1 32bit.
The Webcam worked fine when I did my install a few months ago, and when I fired up Skype today I have no video device.

Just to follow up, I formated and reinstalled the OS. Webcam now works.
Very strange.

OK, it worked for 1 boot, now it’s gone again. Must be a timing issue or
something.

Definitely a timing issue. If i do the rmmod uvcvideo then modprobe
uvcvideo a couple times it works
