Re: [GnomeMeeting-list] Can't get video image

[Damien Sandras <dsandras seconix com>]

Hello,

Sn9c102 is a driver that requires V4L2. However, our V4L2 plugin is
tagged as "experimental". Feel free to fix any problem you encounter.
None of the developers has a V4L2-enabled webcam, so it is not possible
for us to fix anything.

The plugin has been reported to work with some cameras, but it could be
broken for others...

When I say I do, Gnomemeeting then starts normally. At other times, GnomeMeeting just starts without the error. I don't know how to find information which would explain why the error's occurred. I did think that such information could be found in /var/log/messages, but when I looked there I didn't find anything that seemed to me to be relevant. That may be merely a product of my ignorance.

If I then go immediately to Preferences, Video Devices, I'm told I'm using V4L2, which is correct, as far as I can tell, since the sn9c102 driver, as I understand it, supports only V4L2. I'm also presented with a choice of two input devices. One is SN9C10x PC Camera. The other is /dev/video0.
