[Example] Simple MP3 Player (source)

[Dark_sabre]

I made this because I was bored, and wanted to see if there were any simple mp3 players around. of course there was, but none open source so I could modify them. so I put this together quickly, and now everyone else can use it for themselves

Press X to choose a song and it plays

Link doesn't work.
And if this is Lua, it won't be very helpful because MP3 playing in Lua is as simple as calling some functions.

Upload the file with the attachment button in the edit option.

i cant see it being coded in LUA if its the source but maybe.

link fixed. and this is in C.

Nice job, appreciate the effort.
The only thing I recommend against is using libmad to play your mp3s. It's quite slow. You can actually use the psp hardware media engine to run mp3's, and is much quicker.

There was an mp3 player made not long ago which was open source, and made use of the psps media engine. You can check it out here.


PS. In your code, you have no idea why the callbacks are there? Come on. It's what allows your HOME button to function

lol nope, it doesnt tell you on the psp programming tuts, this is his:

And now on to what I like to call the twilight zone. I call it that because at this moment, I have no clue how it works or why, but I do intend finding out some day. Anyway, these functions are necessary for your code.

and

// TWILIGHT ZONE! <do doo do doo>
/* Exit callback */
int exit_callback(int arg1, int arg2, void *common) {
sceKernelExitGame();
return 0;
}

/* Callback thread */
int CallbackThread(SceSize args, void *argp) {
int cbid;

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

sceKernelSleepThreadCB();

return 0;
}

/* Sets up the callback thread and returns its thread id */
int SetupCallbacks(void) {
int thid = 0;

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

return thid;
}
// END OF TWILIGHT ZONE! <do doo do do>

lol

Pretty pathetic when somebody who makes psp programming tutorials doesn't know what that does... :/

It's really easy to understand if you just look at it eh.

SetupCallbacks creates & starts the CallbackThread, which then creates an additional callback thread setting it to do exit_callback when HOME is pressed and YES is selected.

That twilight zone thing was funny. lol

What tutorial did you use? I'm pretty sure the one at psp-programming doesnt say that but its been a while since i read that..

Ha, I have not even begun to learn C++ yet and I can still get the drift of that piece of code as well. Somebody over at a certain site shouldn't be making tutorials...

Anyway, pretty neat. So your basic idea is just to provide this as the core for someone to build maybe something more complex around? Or was this literally just a test of your abilities as a result of being bored? Heh, if it is the former I hope you provide updates.

[Dark_sabre]

bit of both really, I'm planning on making a decent mp3 player or a shell, probably the first of the two , I couldnt compete wuth nervos or irshell :P

and also, the tuts site that I was on was www.psp-programming.com or something like that :P

[TurtlesPwn]

1. Don't make an mp3 player, that's nearly been perfected on the psp.
2. Don't make a shell, that's nearly been perfected on the psp, twice.
3. We know you were on PSP-Programming because that's the domain of the URL to the tutorial to which you were referring.

[slicer4ever]

you guys do know how old those tutorials are right, their from when the damn community was getting started, so you should really think twice about bashing a tut that is very old

days before people fully understood the psp like we do now

[FreePlay]

It doesn't matter how old the tutorial is. People knew then what those functions did. If they didn't, they wouldn't know how to use them.

Exactly, so leave him alone and download this and leave your negative comments away from here.
