[Qugar]

In Ubuntu 9.04 Beta, my webcam in lsusb:
jesus@jesus-portatil:~$ lsusb
Bus 001 Device 002: ID 046d:0896 Logitech, Inc. OrbiCam
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 Device 002: ID 0458:003a KYE Systems Corp. (Mouse Systems)
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

I've the same problem.
In Hardy my webcam Acer Crystal Eye worked out of the box but it doensn't work in Jaunty.

Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 002: ID 062a:0000 Creative Labs Optical mouse
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 006: ID 5986:0102 Acer, Inc Crystal Eye webcam
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

In multimediasystems the parameters are:

plugin: video for linux 2 (v4l2)
pipeline: v4l2src device="dev/video0"

Same for me

Logitech quickcam stx

Works perfectly in Hardy but not Intrepid or Jaunty

Found this article from Launchpad which gave me a solution

Found a workaround for this.

The core of the problem is that gspca drivers in 8.10 apparently implement V4L2, while many applications are still using V4L1 protocol. See http://hansdegoede.livejournal.com/3636.html .

Diagnostics:
install camstream
start camstream, open trace window, and start camera. Expect to see messages like:
VIDIOCSYNC(1) failed (Invalid argument)

How to workaround this (see also https://lists.linux-foundation.org/pipermail/bugme-janitors/2008-October/011912.html):

1. Download and unpack http://people.atrpms.net/~hdegoede/libv4l-0.5.0.tar.gz
2. See README, and install: sudo make install
3. Open terminal window
4. $ export LD_PRELOAD=/usr/local/lib/libv4l/v4l1compat.so
5. $ camstream
Start camera, should now work.

How to make skype work:
1. create new shell script (call it skype_wrapper), put it somehwere (e.g. /usr/local/bin/skype_wrapper). Content:
#!/bin/bash
export LD_PRELOAD=/usr/local/lib/libv4l/v4l1compat.so
skype
2. Open System/Root Menu manager, locate Skype, Edit the shortcut replacing command "skype" => "/usr/local/bin/skype_wrapper".
3. Start skype (restart, if already running). Test video should now work.

Guys, if anyone knows how to **really** fix it (not going thru the pain in the @$$ above), please let me know.

Credit for the solution should go to http://hansdegoede.livejournal.com/3636.html . Errors and typos are all mine ;)

Thank you very much, I've installed the library and run the command,
and the webcam works in aMSN. Yet camorama Cheese and does not work,
but at least I do use it I'm perfect.

== Regression details ==
Discovered in version: Intrepid, Jaunty
Last known good version: Hardy

[Sergio Zanchetta (primes2h)]

I faced the same problem on a friend's laptop.

[Sergio Zanchetta (primes2h)]

Sorry, the upstream bug was closed because it's a problem of applications not supporting v4l2 yet.
On the other hand it could be fixed introducing a sort of external GSPCA as it was in Hardy, waiting for applications like cheese, camorama etc. implementing v4l2 (avoiding the regression).

[Sergio Zanchetta (primes2h)]

There is a bug opened upstream requesting v4l2 support for camorama.
http://bugzilla.gnome.org/show_bug.cgi?id=487119

[Sergio Zanchetta (primes2h)]

Architecture: i386
DistroRelease: Ubuntu 9.04
NonfreeKernelModules: nvidia

Uname: Linux 2.6.28-13-generic i686

[Stefan Bader (smb)]

This will not get fixed in the kernel. The basic problem is you got one driver for a certain piece of hardware. Any more just causes problems. And the gspca driver is working. It is just the applications that need a fix. There is the v4lcompat library that will make v4l1 applications work with v4l2 cam drivers. I thought this was already taken care of on the application side. Unfortunately I did not get any response when trying to find out what the problem there might be.
