Using SDL with PicoGUI
- Originally contributed by Micah Dowty <>
PicoGUI is a scalable GUI system with a unique architecture, primarily focused
on scalability to various embedded systems. You can find more information
including a FAQ at
To use the patch:
1. When compiling, add the "--enable-video-picogui" switch to ./configure
2. When running your program, ensure that the picogui driver for SDL
is in use by setting the SDL_VIDEODRIVER environment variable
to "picogui".
3. The program must also be linked to the C client library for PicoGUI
( If the program is being compiled with a patched SDL
installed this should be done automatically. If you want to use an
existing binary with PicoGUI, you can set the LD_PRELOAD environment
variable to the path of your file.
So far only basic functionality is provided on true color (linear16/24/32)
devices. Accessing a memory mapped bitmap, updating the display, and handling
mouse/keyboard input. This functionality has been tested with several
applications, including mplayer, Xine, sldroids, and Abuse.
TODO list:
- YUV overlays will be helpful for watching video on set top boxes or other
embedded devices that have some graphics acceleration hardware
- Account for rotated bitmap storage in pgserver
- Support for hiding or changing the cursor
- The display should be centered when the SDL application is smaller
than the PicoGUI panel
- Fullscreen or any other special modes
- Support for indexed and grayscale modes
- Probably much more...
