Some very powerful example programs that fully use the VideoCore IV graphics system can be found in the /opt/vc/ directory. Instructions are in /opt/vc/src/hello_pi/README that tell you to first do the following:
make -C libs/ilclient make -C libs/vgfont
then go to one of the example directories, run make, and then execute the newly created executable. For example:
cd /opt/vc/src/hello_pi/hello_videocube make ./hello_videocube.bin
To stop it, use <ctrl-c>.
Note: You cannot run these from a remote terminal. ssh -X only works with X-window programs. These work directly with the VideoCore IV processor.
Try the other examples and study their source code.
