Video woes on Windows 7 x64

Got a shiny newish Windows 7 64 bit box with a AMD Athlon II X4 under the hood. Doesn't want to run the video examples included with processing 1.2.1. Example paper trail:

Could not find QuickTime, please reinstall QuickTime 7 or later.

Exception in thread "Animation Thread" java.lang.NoClassDefFoundError: quicktime/std/StdQTException

at Pixelate.setup(Pixelate.java:43)

Quicktime is, of course, installed. I also uninstalled and reinstalled it a couple of times. What's the deal?

I was having problems earlier mixing 32-bit and 64-bit .dll libraries. Quicktime is only 32 bit. Is this where the problem lies?

Ok I got it to not throw exceptions. Though I wouldn't say it works. Set up a project in Eclipse, imported libraries, followed instructions per this thread: http://processing.org/discourse/yabb2/YaBB.pl?num=1241468327 and configured it to launch with a 32-bit JRE.

The result is wildly colored garbled noise. When I move, it moves, but it doesn't look like me.

Are there any video capture options that use only 64 bit drivers? It would be nice not to have to hack around this...

Hello--

I too was having problems as well with x64 win7 (Home Premium). This is a "native" Windows machine (not OSX running bootcamp or anything like that). I'll outline my whole saga here so that perhaps future victims will have less trouble. I found that by following these two posts:

http://wiki.processing.org/w/Video_Issues - try to get a "clean" install of Quicktime
http://processing.org/discourse/yabb2/YaBB.pl?num=1241468327 - put the QTJava.zip in the right place ([Processing]\libraries\video\library\) and ([JRE]\lib\ext\)

And then, perhaps most importantly, as noted in this post, I made sure that Processing was using an x86 JDK. After getting Processing to acknowledge that QT existed rather than immediately throwing exceptions, I got an error along these lines:

Can't load IA 32-bit .dll on a AMD 64-bit platform

As I already had everything on my machine configured to use the x64 JDK, I changed to the "beginner" install of Processing that comes with a JDK-lite which is conveniently x86 and to which Processing conveniently automatically points. I tried installing both x86 and x64 JDK and using the Registry to get Processing to talk to the x86 JDK instead of the x64 JDK. I used the hints from this post (which you already linked)

http://processing.org/discourse/yabb2/YaBB.pl?num=1211862683

to see which JDK Processing was talking to. However, I was neither clever nor patient enough to get Processing to talk to the x86 JDK instead of the x64 JDK.

I am only making movies, not trying to capture outside video, so I am considering this to be Problem Solved. Also, I was successful running my sketch directly from the PDE; I did not have to go into Eclipse.

I hope this helps!
