Frequently Asked Questions

Here are some of the questions that have been asked a number of times, with my answers.

General questions

Hey, great tool, but will you write a command-line version?

No. (Yes, sometimes I'm blunt. Think about it, though.)

Whenever I switch desktops, minimize the camstream window or do some other heavy stuff on the screen, the program stops with an "error -22".

It's a problem with your motherboard/USB controller. Due to the heavy traffic on the PCI bus to your videocard, the USB controller can't get through and produces an error. There is nothing I can do about that, you may have to fiddle with 'setpci' to give your USB controller more priority (increase the latency timer for USB, lower that of your video card). This is a bit dangerous, though.

Alternatively, buy an AGP video card or a new motherboard.

I've got a Philips cam (or related model), and I can only get a very small image.

This is really a PWC driver issue. You must load the additional PWCX module to get full resolution.

I installed CamStream succesfully, but when I try to run it I get a 'cannot connect to X server :0'

You probably did an 'su' to install camstream and you forgot to log out of superuser mode. This is one of those instances where being root does not allow you to do something (the exact reason is a bit technical). The solution is to logout of your superuser shell, or simply take a different xterm/konsole/whatever and start camstream as your normal self.
