I need some help. I (we if you count ShatterDome and Smerity) am/are trying to read all the .mp3's in the Music folder, and feed them into a buffer so I/we can call 'MP3_Load(mp3bufferhere);' when using libmad lib. So far this is what we have got:
Code:

#include <pspkernel.h>
#include <pspctrl.h>
#include <pspdebug.h>
#include <pspaudio.h>
#include <pspaudiolib.h>
#include "mp3player.h"

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

PSP_MODULE_INFO("Mp3 Player Directory Example", 0, 1, 1);

#define printf pspDebugScreenPrintf

int exit_callback(int arg1, int arg2, void *common) {
          sceKernelExitGame();
          return 0;
}
int CallbackThread(SceSize args, void *argp) {
          int cbid;

          cbid = sceKernelCreateCallback("Exit Callback", exit_callback, NULL);
          sceKernelRegisterExitCall  back(cbid);

          sceKernelSleepThreadCB(); 

          return 0;
}
int SetupCallbacks(void) {
          int thid = 0;

          thid = sceKernelCreateThread("update_thread", CallbackThread, 0x11, 0xFA0, 0, 0);
          if(thid >= 0) {
                    sceKernelStartThread(thid  , 0, 0);
          }

          return thid;
}

struct songinfo
{ char songname[255];} ;

struct songinfo playlist[100];

int getsonglist(void)
{
int dfd;
SceIoDirent songdir;
memset(&songdir, 0, sizeof songdir);
char buffer[255];

int songcount = 0, maxsongs = 0;

dfd = sceIoDopen("ms0:/PSP/MUSIC/TEST/");

while(sceIoDread(dfd, &songdir) > 0)
{
//sceIoDread(dfd,&songdir);

sprintf(playlist[songcount].songname,"%s",songdir.d_name);
maxsongs = songcount;
songcount++;

} // while sceIODread
sceIoClose(dfd);

return maxsongs;
} // int

int main()
{
pspDebugScreenInit();
SetupCallbacks();
pspAudioInit();
SceCtrlData pad;

char songpathbuf[255];
int songcounter = 1, change = 0, numsong = getsonglist();


MP3_Init(1);

songcounter++;
sprintf(songpathbuf,"ms0:/PSP/MUSIC/TEST/%s",playlist[songcounter].songname);

printf("songpathbuf == %s\n", songpathbuf);
MP3_Load(songpathbuf);
MP3_Play();
while(1) { //wait for X to be pressed
    sceCtrlReadBufferPositive  (&pad, 1);
    if(pad.Buttons & PSP_CTRL_CROSS) break;

    if(pad.Buttons & PSP_CTRL_CIRCLE) MP3_Pause();

    if(pad.Buttons & PSP_CTRL_RTRIGGER) { change = 1; songcounter++; }

    if(pad.Buttons & PSP_CTRL_LTRIGGER) { change = 1; songcounter--; }

    if(MP3_EndOfStream() == 1) { change = 1; songcounter++; }

if (change == 1)
{
MP3_Stop();
MP3_FreeTune();
if (songcounter > numsong) songcounter = numsong;
if (songcounter < 1) songcounter = 1;

sprintf(songpathbuf,"ms0:/PSP/MUSIC/TEST/%s",playlist[songcounter].songname);

printf("songpathbuf == %s\n", songpathbuf);

MP3_Load(songpathbuf);
MP3_Play();
change = 0;
} // if change == 1

} // while
MP3_Stop();
//MP3_FreeTune();

sceKernelSleepThread();

return 0;
}

Now, others have done this and it works, but I have edited ita little so it works with my code, and it complies alright, but i get this when running (using printf I believe):

Anyone know how I could read all the .mp3s from the MUSIC folder and load them using hte library libmad?[/code]

Ok, I got it to

    Ignore non-Mp3 files
    Select previous and next files using L and R


What I haven't got it to do yet is -

    Ability to select directories
    Reset the timer so it starts at the start of the next song


Any help on the latter two would be good...

Code:

// Mp3 Directory Player, original code by Shatterdome, improved on by Smerity

#include <pspkernel.h>
#include <pspctrl.h>
#include <pspdebug.h>
#include <pspaudio.h>
#include <pspaudiolib.h>
#include "mp3player.h"

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

PSP_MODULE_INFO("Mp3 Directory Example", 0, 1, 1); // name, other, major, minor

#define printf pspDebugScreenPrintf

int exit_callback(int arg1, int arg2, void *common) {
          sceKernelExitGame();
          return 0;
}
int CallbackThread(SceSize args, void *argp) {
          int cbid;

          cbid = sceKernelCreateCallback("Exit Callback", exit_callback, NULL);
          sceKernelRegisterExitCallback(cbid);

          sceKernelSleepThreadCB();

          return 0;
}
int SetupCallbacks(void) {
          int thid = 0;

          thid = sceKernelCreateThread("update_thread", CallbackThread, 0x11, 0xFA0, 0, 0);
          if(thid >= 0) {
                    sceKernelStartThread(thid, 0, 0);
          }

          return thid;
}

struct songinfo
{ char songname[255];} ;

struct songinfo playlist[100]; //an array of 100 structures of type songinfo (which only holds one variable, but can hold as many as you want...
// This function reads all the songs in the psp/music dir and feeds them into that playlist[100] array, easier to work with...

int getsonglist(void)
{
int dfd;
SceIoDirent songdir;
memset(&songdir, 0, sizeof songdir);
char buffer[255];

int songcount = 0, maxsongs = 0;

dfd = sceIoDopen("ms0:/PSP/MUSIC/");

while(sceIoDread(dfd, &songdir) > 0)
{
//sceIoDread(dfd,&songdir);

sprintf(buffer,"%s",songdir.d_name);
// debug - printf("buffer == %s\n", buffer);
char *suffix = strrchr (buffer, '.');
if (suffix != NULL)
{
if (stricmp (suffix, ".mp3") == 0)
{
sprintf(playlist[songcount].songname,"%s",buffer);
maxsongs = songcount;
songcount++;
} // != NULL
} // == 0

} // while sceIODread
sceIoClose(dfd);

return maxsongs;
} // int

int main()
{
pspDebugScreenInit();
SetupCallbacks();
pspAudioInit();
SceCtrlData pad;

char songpathbuf[255];
int songcounter = 0, change = 0, numsong = getsonglist();


MP3_Init(1);

pspDebugScreenSetXY(2, 4);
if (numsong < 1) printf("No songs in folder...\n\n");

sprintf(songpathbuf,"ms0:/PSP/MUSIC/%s",playlist[songcounter].songname);

printf("songpathbuf == %s\n", songpathbuf);
MP3_Load(songpathbuf);
MP3_Play();
while(1) {
    sceCtrlReadBufferPositive(&pad, 1);
    if(pad.Buttons & PSP_CTRL_CROSS) break;

    if(pad.Buttons & PSP_CTRL_CIRCLE) MP3_Pause();

    if(pad.Buttons & PSP_CTRL_RTRIGGER) { change = 1; songcounter++; }

    if(pad.Buttons & PSP_CTRL_LTRIGGER) { change = 1; songcounter--; }

    if(MP3_EndOfStream() == 1) { change = 1; songcounter++; }

if (change == 1)
{
MP3_FreeTune();
MP3_Stop();
if (songcounter > numsong) songcounter = 0; // repeat from start
if (songcounter < 0) songcounter = 0; // compensate for . and .. but will be fixed when we can ignore non Mp3s

sprintf(songpathbuf,"ms0:/PSP/MUSIC/%s",playlist[songcounter].songname);

// debug - printf("songpathbuf == %s\n", songpathbuf);
// debug - printf("songcounter == %i\n", songcounter);

MP3_Load(songpathbuf);
MP3_Play();
change = 0;
} // if change == 1

} // while
MP3_Stop();

sceKernelSleepThread();

return 0;
