vimage problem

hello,
nice the new revision is out!!!
just wanted to try the videocapture stuff but i cannot get it run... i used the examples from the manual, eg. for beginvideo() but proce55ing always says that variable vimage is not defined in the current context... same for vpixels.
maybe i missed something, but i tried the normal & expert version, have the newest JRE installed, Quicktime 6.1 pro with quicktime for java, win xp sp1, dell 8100 laptop/512mb/gforce2 go ..
anyway, proce55ing rocks! 
greets from amsterdam

we've gone a different route than what's documented. not sure which version will be final, but for now, 'video' is an image (instead of vimage), so then to get the width, height, and pixels of it, you use video.pixels, video.width, and video.height.

Does anyone have a working example of how video works now? Is it possible to construct an image by doing something along the lines of:
BImage vid;
void setup() {
size(360, 240);
noBackground();
beginVideo(360, 240, 24);
}
void videoEvent() {
vid.pixels = video.pixels;
vid.width = video.width;
vid.height = video.height;
image(vid,0,0);
}
void loop() {
}

there are some bugs in video in release #55. we're fixing for release #56 (sometime next week).
here is how it will look:
Code:void setup() {
size(320, 240);
noBackground();
beginVideo(320, 240, 24);
}
void loop() {
image(video, mouseX, mouseY);
}
public void videoEvent() {
// Set variables or booleans for updates
// but don't draw within videoEvent
}

aren't videoEvent and loop running in different threads? will they be synchronised, or is there some cool behind-the-scenes way of loop grabbing synchronised imaging from videoEvent?

they're running in different threads, but if we add any sort of synchronization, it'll be so that loop() is tighter.
drawing inside videoEvent is "unsupported."
