2) or how i can get array of array frame data i RGB massiv of massives (for example 122,222,222 for one pixel with num of 123)?
3)

Hi everybody,
i wrote a C++ wrapper lib and based on that some perl bindings that let me execute this little script attached at the bottom.
It can be downloaded at:

Best regards, Torsten.
