RE: Help with Java and QuickTime

The love of QTJava. Well there's as always lots of ways to do stuff
using QTJava. I get a java.awt.Images from QT is like this:

/// mp = MoviePlayer
QTImageProducer qtProducer = new QTImageProducer(mp, imageSize);
Image javaImage = Toolkit.getDefaultToolkit().createImage(qtProducer);
BufferedImage bi = new BufferedImage(r.getWidth(), r.getHeight(),
BufferedImage.TYPE_3BYTE_BGR);

This works with any image format or video. Now the image u are getting
from your SequenceGrabber maybe having hassle. Try going the getGWorld
route, it's a little harder but it ways seems to work out in the end.
Also u could try passing the QTImageProducer the SequenceGrabber (prob
wont work mind).
