I'm building a patch that renders 6 videoplanes to a single window.
I'm hopinng to work with short animation-compressed qt's with alphas stored in RAM for speed. Hopefully at around 512x512 size.
I'm hoping for a frame rate of 30fps. I'm getting about 25fps.
I'm running a dual g5 2.0ghz with an ATI 9800 card.The CPU activity monitor is running at about 50% per processor.
I've been testing with textures that are 256 x 256, mostly tiff files with alpha channels.
Reducing the size of the jit.qt.movie dimensions seems to increase the frame rate a little, whereas raising drops the frame rate.
Where are the big bottlenecks?
If you can run 4 dv movies at full speed, surely 6 movies is no biggie.
Will look at colourspace options, but are there any other speed bumps?
Should I be getting more than this? Am I overloading the gl card? Surely not.
I am running 6 x fft's on audio at the same time, but this seems to be negligable.
