+*****************************************
+ *** SDL Example: audio player for apf ***
+ *****************************************
+
+
+Music Player for apf9328 (and apf27 ?)
+Requires SDL, SDL_ttf and SDL_mixer libs
+Audio format supported: WAV ...( + OGG on host computer)
+Date: 24/05/09
+Version: 1.0
+Author: rebouxan
+
+*** Repertories ***
+
+ * data: contains the background, fonts and icones ...
+
+ * music: here you have to drop the music you want the player to read.
+ Files must have the same audio_rate which is (#)DEFINEd in player.c by AUDIO_RATE.
+ /!\ You have to limit song files' carateres at 10 or a little more. exemple: musiciswav.wav
+
+ You can change the music directory and take for instance /mnt/mmc to play your SD card on your apf
+ by changing MUSIC_DIR var in player.c before compilation or by executing the player with the repertory
+ you want to read in arg: for instance, #./aplayer /mnt/mmc
+ /!\ Try to limit pathnames' carateres.
+
+*** keyboard commands ***
+You can see keyboard commands in player.c -> function 'handleKey()'
+The main commands are:
+ -"o": play/stop
+ -"p": pause stop
+ -"-/+": volume down/up
+ -"q": quit
+
+
+*********************
+*** x86 Compiling ***
+*********************
+
+1/ Install all required libs
+ * On Red Hat-like distrib:
+ # yum install SDL SDL_ttf SDL_mixer
+ # yum install SDL-devel SDL_ttf-devel SDL_mixer-devel
+
+2/ Compile the code
+ In the player directory, execute:
+ $ make
+
+3/ Put some WAV or OGG files in "music/"
+
+4/ Enjoy :) => $./fplayer
+
+5/ Cleaning: $ make clean
+
+
+*********************
+*** ARM compiling ***
+*********************
+
+1/ Install all required libs
+ * Go to armadeus repertory
+ * $ make apf9328-menuconfig
+ * select "package selection for the target"
+ * select "SDL", "SDL_ttf" and "SDL_mixer"
+ * $ make
+
+2/ Compile the code
+ $ make TARGET=arm
+
+3/ If SDL libs were not installed, update your apf rootfs to have SDL libs on your board
+
+4/ Put the executable (aplayer) with data and music repertories on the board
+ Plug a usb keyboard on your devFull
+
+5/ Load the sound modules:
+ modprobe spi_imx
+ modprobe snd-imx-alsa-tsc2102
+ modprobe snd-pcm-oss
+ modprobe snd-mixer-oss
+
+6/ Execute: #./aplayer
+
+7/ Cleaning: $ make TARGET=arm clean
