I made a simple player, it plays MP3 and OGG, but it doesn't work.

It gives me this errors:

Makefile:

BUILD_PRX = 1
EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = File Browser

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



The file is compiled but give black screen on my PSP, any idea?

you have several warnings that tells you have some problems, at the end of your compilation you should NOT have any errors NOR warnings.

eg. :
Code:

main.c:106: warning: comparison between pointer and integer 


I think it's in Audio_Play()

you have:
Code:
   if(MediaType=="mp3") 


you are comparing MediaType (which I didn't find any definition ? did you give all the code ?) and "mp3".

whatever the type of MediaType you can't compare strings using == you have to use strcmp (or stricmp or strncmp etc etc )

so (MediaType=="mp3") will always be false.



later you wrote :
Code:
                   MediaType = "mp3"; 


is MediaType an int or a char * ?

always in this function :

you said that this function returns an int

Code:
 int Audio_Play(char *filename)


but it returns nothing ...



so you will have to:

1) correct all the warnings. => if there is one you don't understand we can help you.

2) give all the code, otherwise we won't be able to help you.

I believe MediaType is a char but only pointers can be "assigned" like:
MediaType = "lalala";

what you must do is use sprintf or strcpy

if(MediaType=="mp3")

you can't do this, it's not C#.

You need strcmp.

There are some platforms that use four byte characters, so you can do this:

char x = 'mp3 ';

...

if (x == 'mp3 ')

CodeWarrior for the PPC Mac was that way. I used four-byte chars on it all the time. This was before OSX.
