These files contain the audio support for iPhone. They are based on the CoreAudio audio driver for Mac OS X. The principle difference is that the iPhone doesn't seem to have a concept of audio devices ... it just has special units for audio in and audio out. Also had to change some functions to versions which seem to only exist on iPhone and will apparently exist in Mac OS X 10.6(!)

There is currently no audio recording support -- my iPod Touch doesn't have a microphone to test this with.
     1 SDL on DirectFB
     2 
     3 Supports:
     4 
     5 - Hardware YUV overlays
     6 - OpenGL - software only
     7 - 2D/3D accelerations (depends on directfb driver)
     8 
     9 What you need:
    10 
    11 DirectFB 1.0.0 - required
    12 Kernel-Framebuffer support: required: vesafb, radeonfb .... 
    13 Mesa 7.0.x	   - optional for OpenGL
    14 
    15 As of this writing 20070810 you need to pull Mesa from git and do the following:
    16 
    17 ------------------------
    18 cd mesa 
    19 make linux-directfb
    20 make
    21 
    22 echo Installing - pleaser enter sudo pw.
    23 
    24 sudo make install INSTALL_DIR=/usr/local/dfb_GL
    25 cd src/mesa/drivers/directfb
    26 make
    27 sudo make install INSTALL_DIR=/usr/local/dfb_GL
    28 ------------------------
    29 
    30 To run the SDL - testprograms:
    31 
    32 export SDL_VIDEODRIVER=directfb
    33 export LD_LIBRARY_PATH=/usr/local/dfb_GL/lib
    34 export LD_PRELOAD=/usr/local/dfb_GL/libGL.so.7
    35 
    36 ./testgl
    37 
    38 To use hardware accelerated YUV-overlays for YUV-textures, use:
    39 
    40 export SDL_DIRECTFB_YUV_DIRECT=1
    41 
    42 This is disabled by default. It will only support one concurrent 
    43 overlay and may behave strange if not used with SDL_CreateYUvOverlay
    44 from SDLcompat.c.
