I have a Logitech QuickCam Communicate STX webcan that was plug and play when I bought it a few years back. I have used it a few times on Skype when it seemed okay, but have been trying to use it with Google+ Hangouts. There I found that it would be okay at first, but then the picture would freeze. Sound through the built-in microphone is fine.

I wondered if it was the Google plug-in, but just doing some experiments with Cheese and that freezes too. I can seem to un-freeze that (for a second or 2) by waving a hand in front of the camera. Could something be shutting down if it doesn't detect enough movement?

I'm running Kubuntu 11.10. Any suggestions on things to look at?

Many applications, like webcams, doesn't seem to work well (or at all) with V4L2. But luckily there is a simple workaround to avoid the problem, through installing and loading some libraries with backward-compatibility with V4L, so that Flash sees again your Webcam, as it used to do until Ubuntu Hardy.

sudo apt-get install

after that execute:

sudo /usr/lib/libv4l/

Then, you have to switch the video mode to V4L from the multimedia systems selector, through executing the following in a terminal:


Go to the Video tab, and change the default value to V4L.

thanks for finding the source... I had cut-n-pasted that to a set of notes I have for my kids computers and did not have the source. They are on 11.04 so it looks like I too will be looking for a new set of instructions. – cprofitt Mar 20 '12 at 15:32
