OK, the Java Virtual Machine doesn’t like it when you try to use more memory than processing has allocated.
A compressed movie may be a few MB or less, but when it is made in to a video cube the size can grow massively. For example a 2.4MB MotionJPEG movie takes up nearly 160MB as a serialized object. Once the size of the videocube object exceeds the memory allocation things break and out of memory errors ensue.
The lab G5’s have 256MB of memory and processing can be allocated all of that, but it’s not really going to cut it with even a 5MB movie. Presumably giving processing all the memory will result in page swapping because the OS needs something too, so performance will not be so great either.
I guess this is just a limitation of the videocube idea. Not sure how to deal with it.
