Hi! I have read through the GeodeLX documentation and I noticed that its DC can output a video stream over the normal (1200x900) frame buffer. Can the X11 developers create a mode with the following spec?
1. Software can request allocating two YUV (4:2:0 or 4:2:2) frame buffers in the Software's address space with the given dimensions (eg 400x300). 2. Software can request displaying one of those frames in the defined size (as I understand the DC will upscale the video if needed). 3. Software can render in YUV to one of the frames. 4. Software can request flipping to the other frame. (If I read correctly the switch will happen on vsync.) 5. goto 3. (The Software can start rendering (vertex transformations/triangle setup/lightning) but have to wait for the vsync somehow...) 6. And now we have an usable display system for an OpenGL implementation. Is it possible to implement? If so I would like to write a 3d software renderer since it is fun. :) ps: Using YUV for white lights is even better than RGB. _______________________________________________ Devel mailing list Devel@laptop.org http://mailman.laptop.org/mailman/listinfo/devel
