Hi! I have a question - is SDL_mixer hardware accelerated? When I load ogg file,and play it using sdl_mixer,my game slows down like 50%. I thought that sound decoding is accelerated by some hardware inside psp,not by main CPU?

Ok.Is there any lib that accelerates audio decoding?I would really like to implement music in my game,but if it's hogging up my program will have to disable it.

So far as I know ME audio codec doesn't support OGG format (not that it cannot but Sony probably doesn't support OGG anyway). If it is not an obstacle, you can use MP3 files instead through CoolEyes' audio decoding stuff in this forum (as already pointed by Insert_witty_name). |
