[jitsi-users] quickcam express usb video camera is not seen by jitsi


#1

Hi,

I've installed jitsi_1.0-beta1-nightly.build.3560_i386.deb on Debian Testing
and my video camera is not available in the options. The select dialog for the
video input device is just empty.
The camera is however available. It works via vlc v4l2:///dev/video0
I'm using openjdk6.

*I have solved many webcam problems with various applications by using V4L1 compatibility mode. You need to have the library installed (package libv4lO on ubuntu). The mode is invoked with the following command by preloading the lib when starting the application:

LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so jitsi

It sounds like Jitsi does not currently support the GRBG video4linux2
pixel format. Could you please open an issue to track its development?
