annotate src/video/windib/SDL_gapidibvideo.h @ 4165:3b8ac3d311a2 SDL-1.2

Hello. This patch provides basic support for video on the Sony PS3 Linux framebuffer. Scaling, format-conversion, and drawing is done from the SPEs, so there is little performance impact to PPE applications. This is by no means production quality code, but it is a very good start and a good example of how to use the PS3's hardware capabilities to accelerate video playback on the box. The driver has been verified to work with ffplay, mplayer and xine. This piece of software has been developed at the IBM R&D Lab in Boeblingen, Germany and is now returned to the community. Enjoy !
