MP3 Playback sample code

[Shapyi]

I hear libmad is used to decode MP3s. I am new to libmad and I was wondering if anyone had any sample code or source code on how to play an MP3 on PSP. I am making a simple 2D game and I would like music in it. Thanks.

Alright, I downloaded libmad, compiled it and typed "make install". But it doesn't put the include file and lib file in any directory. I put mad include in the right directory, but no matter where I put libmad.a, my program doesn't compile, I get

Code: Select all

/usr/local/pspdev/lib/gcc/psp/4.0.0/../../../../psp/bin/ld: cannot find -libmad
collect2: ld returned 1 exit status

Here is my make file

Code: Select all

TARGET = gamesdk
OBJS = main.o pg.o mp3player.o

INCDIR = 
CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)

LIBDIR = 
LDFLAGS =
LIBS= -lpspgu -lpspaudiolib -lpspaudio -libmad

EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = Test App

PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak

Can anyone help?

Perhaps -lmad will do (provided the lib can be found in your searchpaths somewhere)

Yup. That did it. Thank you.

And if anyone is reading this thread and is interested in MP3 Decoding I used the source code from PSPMediaCenter by John_K. Worked like a charm.

Works like a charm, but this thing is killing my fps !!! :/
I'm really bad when it comes to audio, I guess mp3 is quite cpu intensive, isn't there a way to use the ME for this (and how?^^), or is there another format I should be using instead, which would be a little bit lighter on the cpu ??
