Load Video Library on Web
Sep 19th, 2005, 9:59pm  
Hi,i tried searching for this but i didnt find a solution for my problem.

I have a program that imports the video library to use a web cam. The problem is that i cant run the the program as an applet.

Is it possible to have an applet that use a webcam? If its not possible, is there a way a third user could run my program without processing?

Thanks in advance.

You won't be able to run an applet inside a browser using the video library. It will only function locally.

If it's only intended for use by a third party without processing you could perhaps put it together as an APP.

I've not tried it with video, but can't see why not.

Thanks Mark for the answer.

I tried to run the program but i only get a black screen with a close button and the next error :

Code:

Exception in thread "Thread-2" java.lang.NoClassDefFoundError: quicktime/std/Std
QTException
	  at ghostbuster.setup(ghostbuster.java:13)
	  at processing.core.PApplet.display(PApplet.java:1050)
	  at processing.core.PGraphics.requestDisplay(PGraphics.java:362)
	  at processing.core.PApplet.run(PApplet.java:951)
	  at java.lang.Thread.run(Unknown Source)


Do you know what the problem is?

When exporting for the web it looks as though the quicktime stuff is omitted. Hence the NoClassDefFoundError.

This is a security issue I believe, as activating peoples webcams is not an ethical business. Saying that, it might be possible to overcome this and have people sign your applet as trusted!

Do you actually need live camera feed? Or could you compile a .mov for viewing on the web?

anything can be used standalone (video, opengl, whatever) it's just a matter of knowing enough of how to get it working. it's not particularly fun to do, as you can see from the posts over in the integration board. Undecided
