You could write an object like pix_buffer_mix that made a composite out of all of the frames.  Look at pix_mix for the basic RGBA and YUV loops and then wrap a loop around that while moves over each frame in the buffer.  This will not be all that fast and doubtfully run at 30fps with hundreds of images in the buffer.

Hi Chris,

I have used SB before for this, but in this case I need more flexibility
(and the images should not build up over time but be combined from the
first frame.

Seems like I may have to delve into some C++ to do the math manually.
Will that be too slow though? iterating over the data in a pix_buffer
should be fast right?

If anyone has some sample code along these lines please let me know.
