Did you read the second part of the page?

Quote:

If you are not using an Apple computer, you will also need a VDIG, a video driver that translates from your hardware to the video functions used by QuickTime. This software may be included in the software provided by the maker of your hardware, or you can download the free VDIG available at http://www.vdig.com and check if it is compatible with your video camera. The free VDIG is slower than many you pay for. There's more information about this below...

Hi,

yes, I installed the VDIG also but I still get:

"Problem connecting video output to the hardware renderer" from VDIG and from processing:

quicktime.std.StdQTException[QTJava:6.1.5g],-9405=couldntGetRequiredComponent,QT.vers:7158000
at quicktime.std.StdQTException.checkError(StdQTException.java:38)

It looks like no support for this hardware or what? It is a cheap web cam from speed link.

By the way I downloaded QuickTime but I don't get an additional point "custom" to install QuickTime for Java.I used the QuickTime installer from the Quick time web page. But the installation had no point custom...

What can I do now? I need the web cam support in processing urgent

first thing to do is look (search) for "qtjava" after installing quicktime. if it is there try running one of the video examples (not capture, try a playback one). if that runs quicktime is ok.

next thing is vdig. if you followed the instructions on the page above and it's not working, then you can try reinstalling vdig. i'm not sure how to test vdig .. i'm on a mac. if you find out that vdig is working, than probably your webcam is not supported ... maybe try a different one.
