Flash/Quicktime playback on Mac

Our SDL-based engine can play Flash files on Windows. To do so, we use the
Flash ActiveX component, hide the window, let audio play normally, and then
grab the contents of the (hidden) window into a memory buffer which can be
passed to SDL_CreateRGBSurfaceFrom().

Now we want to do this on the Mac. Apparently Quicktime plays SWF and
apparently there’s a way to have Quicktime render to an offscreen buffer,
but I haven’t been able to find a simple code example of this in the Apple
developer website - is any of you doing something like this?

Any tips are extremely appreciated!
