Description Zuirdj 2005-04-19 00:31:43 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050416 Fedora/1.0.3-2 Firefox/1.0.3

Description of problem:
I have a webcam that Fedora supports with the sn9c102 driver included in the kernel. But the driver uses V4L2 and not V4L. Gnomemeeting supports V4L2 since 1.2 but pwlib needs to be compiled with --enable-plugins --enable-v4l2, according to 

Suse has a plugin to resolve the same issue http://rpm.pbone.net/index.php3/stat/4/idpl/1667803/com/pwlib-plugins-v4l2-1.8.3-3.1.i586.rpm.html

More about this in

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Connect my webcam
2. sn9c102 driver, precompiled in kernel, detects the webcam
3. Gnomemeeting doesn't recongnize it.

Expected Results:  Webcam working! :-)

It's possible to include this enhancement in FC 5?
Comment 2 Túlio Miranda Barros 2005-08-26 17:55:43 EDT
Mandrake has solved the problem too. The RPM packs of our distro lacks the file
v4l2_pwplugin.so present on theirs as you can see from:

The same happens with my webcam D-Link DSB-C110 (Fully supported by Mandrake and
Suse) and only recognized by Fedora.

I just tested the "ubuntu in live" version 5.04 and, from cd, without installing
anything, the webcam works perfectly.
Comment 4 Peter Robinson 2005-08-31 05:53:09 EDT
Its just a matter of compiling with the option of --enable-v4l2 on the configure
command line of pwlib
Comment 5 Daniel Veillard 2005-09-05 09:05:26 EDT
According to Damien Sandras gnomemeeting upstream maintainer:

  v4l2 is not stable, not maintained
  it should not be activated by default
  if activated it should be in a separate package
  activating by default like in Ubuntu and Debian is a serious mistake

So it is definitely not a simple matter of adding --enable-v4l2 on the command

Comment 6 Zuirdj 2005-09-05 11:53:12 EDT
"if activated it should be in a separate package"

Maybe a separate package in Extras would be a good idea?
Comment 7 Zuirdj 2006-01-04 20:39:13 EST
any news about this enhancement?

Comment 8 Zuirdj 2006-03-15 14:55:43 EST
Today I probed the new ekiga 2.0.1-1 and pwlib 1.10.0-1. My SN9C10x webcam
(supported by V4L2) is working OK now. Thanks for your work!
