Old webcam and new Ubuntu with Skype
I did a lot of googling to try to fix this problem myself without finding it, so I'm putting this out there in case it helps anyone else speed up the process.
I have a Logitech QuickCam Express (lsusb ID 046d:0840 ). It's older than dirt. Meanwhile, I'm running Quantal / 12.10 with GNOME. I plugged the camera in, installed skype, and like a fool, expected it to work. No image on the video device screen. For some reason Cheese is fatally broken on my system. I google and find the Ubuntu webcam page and try:
Now this works. So I root around some more and find a page that tells me to try
I'm told this can't be preloaded. I install v4l-utils (and you should too) but this doesn't fix the problem. After a lot of googling and trying different things like gstfakevideo, which I cannot even get to compile on my system, I decide to investigate whether this path even exists. Lo and behold, someone has moved things around and the proper path is now
So either export this or write a script to run skype with that environment variable. Also, the above is what you want, not x86_64-linux-gnu and not v4l2convert.so.
