Video buffer is a completely independent parameter. You can't infer it from the others. It's how much memory you are requiring the player to have to decode your video.
On software decoders, you can set this pretty high, because everyone has lots of RAM at their disposal. On hardware decoders, they have a fixed amount of RAM. Their video buffers were pre-determined at the factory, and they can't just allocate more memory. Therefore, you're stuck with whatever video buffer size your hardware player has.
