Blue Screens and Webcams

I did a search and came across a post regarding this subject. The suggested fix was to bring up device properties window to prevent the crash, which was due to the video settings being an indeterminant format. That worked, however, I need a means of auto-configuration.

The setup we have here is a machine running some monitoring software, and it also has two Logitech QuickCam Chat USB cameras attached. This machine is running Windows XP and the latest nightly build of 0.82 (for HTTP authentication). On startup, two instances of VLC are launched from simple shortcuts in the Startup directory. When we were testing using the old cameras we had (Some Creative camera, and a different Logitech one), this would work properly for one camera, but not for the other. I now know the other suffered the same image format problem, as it often resulted in a bluescreen if I attempted to use it.

The problem now is, I need to show the device properties window for the camera to function properly. Is there a way to set device properties without having to present the user with the device properties box?


Also, it seems that there is an issue also relating to these bluescreens where VLC will crash or startup. Once it starts, it will continue to crash. It sounds like some sort of corruption issue, as when I downloaded the newest nightly build, it began working again, but now, again, crashes on startup.

One last issue that I anticipate encountering is using two cameras of the same name. In the device list in VLC, both appear with the same name, so I'm a bit confused as to how I'll select one or the other for the two VLC instances.

Any advice or help would be appreciated.

mixtar suggests that you include the video size (eg :dshow-size="640 x 480" ;spaces are important)

It worked for me.
