    I gotcha now. I was thinking you meant you defined a dynamic buffer function into the software.

    Do you mean you're simply using the standard C++ Quicktime I/O API buffer?

    there are many types of buffers. i use many different types of buffers and queues.
    i use at least 4 different types of fifo - they are required to do simple things... its quite complex getting all this stuff onto the screen from different sources.... at different frame rates ( and now everyone uses triple heads and double heads, and all that stuff which totally confuses the graphics card... )

    i dont use any c++, i dont use quicktime buffering directly -

    but quicktime has its own decompression buffering strategies for multi-processing handling and sending out jobs to decompress frames.
