The subject says it all basically. It did work before my last sync.

Skype detects the camera but fails to start video. No messages on the terminal or such. revdep-rebuild was run, ldd /opt/skype/skype shows no unresolved libraries.

I can also use xsane and mplayer to get stills and video from the camera.

The camera driver is gspca_zc3xx. It's a Logitech something or another.

Does anyone have an idea of what's wrong with it?

Update

I have found the issue.

The update somehow zapped one of the scripts or perhaps a .desktop that I have modified, wich had
Code:
LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so
in it!

And the saddest thing? It's not the first time this happens to me.

What is the best way to set this variable (for skype only!) once and for all, so that no future update breaks it?

My experience is that video in skype is hit or miss without ever being able to nail it down to anything specific. Certainly for the past few years, I've seen video work or not work, and a reboot sometimes fixes it. I've come to suspect that maybe the camera hardware randomly doesn't get initialised correctly after reboot, implying some kind of hardware issue. This is a builtin USB camera, and I've been using the uvc driver since before it was part of the kernel. That's kernels 2.6.2x up to 3.2 and whatever uvc driver version was current or included at the time.
Code:

Bus 002 Device 006: ID 05a9:2640 OmniVision Technologies, Inc. OV2640 Webcam


Just as an aside, responding to this post gives me an eerie feeling since I've been using pygoscelis in other forums ;-)

Thanks. Unfortunately, the reboot didn't help.

When I try to test the camera in Skype, nothing at all happens. When I run a capture with mplayer, it blinks a LED and the driver puts a message in the kernel log:
Code:

zc3xx: probe 2wr ov vga 0x0000

I have already tried skype with static Qt, and a previous version, and run as root. [/code]Nothing. Oh well...

Oh yeah, there's that. I've masked skype > 2.1.0.81. Still. I do see intermittent problems as described with this version.
