Hi all, I have a platform on which I want to optimize speed of full screen mpeg4 playback (800x600). The platform is arm based and the graphics chip is SM722. The SM722 chip does not have mpeg4 acceleration integrated but support for other hardware accelerated graphics. The framebuffer driver we use today offer no hardware accelerated graphics.
Is there a good way to find out what DirectFB functions that are called when I setup mplayer to play an mpeg4 stream with directFB as video output driver? I have created a SM722 directFB skeleton driver that compiles and loads but with all drawing and blitting flags set to "none". As I am not experienced in graphics driver development the idea is to implement the "easiest" and most efficient functions for full screen mpeg4 video acceleration first. Suggestions for other approaches to optimize mpeg4 playback are always welcome. / Olov
