SDL with MiniGUI?

I am developing a digital video software. In this software, I use SDL to
play

H.264 video and minigui to build GUI.

But SDL cannot work with minigui. How to do?

minigui: http://www.minigui.com

Can I let player(SDL program) be in a rectangle?

Can I let SDL_Init and SDL_SetVideoMode don't effect fullscreen, but a

rectangle?
