thanks

thanks! mp3 under 3.xx kernel
will you release a sample for mp3 usage? and I suppose we cannot read the id3 tags?

MP3 is intended for background music and you don't really need ID3 tags for this.
For ID3 you can check LightMP3 source code (players/id3.c).
You can download source code here:
http://sakya.altervista.org/new/index.php?mod=Downloads

Check this for a sample (it's Super Patrick from Brunni's samples adapted for kernel 3.xx):

You don't need to use different threads (as in Super Patrick II) I'm just too lazy to remove it.

Ok many thanks!

Good job on the mod, the super patrick example compiles and plays fine now. Now, I have to brush up on my french, because it doesn't matter how well something is comments, when its commented in a different language, it still doesn't help. lol.

Ciao Sakya!

in your next release, can you please include some VFPU functions like tan, acos, asin, atan etc... they are available in there: http://forums.ps2dev.org/viewtopic.php?t=7539
I had to hack this a bit to be able to use it (vfpu_sinf & vfpu_cosf already declared in oslib + extern C statement not closed). it would be nice to have oslATan oslRandom etc available.

Thanks!

edit: maybe inlining them would improve things too... edit2: no doesn't seem to.

[daaa57150]

I tried to play an mp3 and I spent some time before it worked
Maybe you should explain what's mandatory in the documentation Sakya:

PSP_HEAP_SIZE_KB(12*1024); is mandatory (freezes otherwise)

playing mp3 with OSL_FMT_STREAM is mandatory (says it cannot find the file with OSL_FMT_NONE)

in the makefile,
BUILD_PRX = 1
PSP_FW_VERSION = 371
is not mandatory, I use PSP_FW_VERSION = 150

using 2 threads is not mandatory, I use only 1 in user mode.

note that I tested this on my PSP phat with fw 3.71 m33-4, I will try to test it on a slim PSP, but if someone knows what's needed so it works on both + old firmwares, let me know!

hy, first excuse my poor english . . .

i have this error :

C:/pspdev/psp/sdk/lib/libosl.a(media.o): In function `initME':
audio/media.c:172: undefined reference to `sceUtilityLoadAvModule'

it's about PSPUTILITY_AVMODULES but i havent found it . . . .

could you help me ?

Update your pspsdk.

Ciaooo

[Sphax]

YEs, but how.

I'm working with pspdev, not directly with cygwin ?

Where can i found the last pspsdk (question for everyone) ?

Tks a lot

Edit: Après MAJ du PSPSDK , ca fonctionne bien mieux , merci Sakya

[Dr.Vince]

hello, maybe someone could help me.

I tried to compile Super Patrick (see link above) but this don't work on my PSP.
In 1.50 it crashes and in 3.90 I got the error 8002013C.

I also tried to comment

BUILD_PRX = 1
PSP_FW_VERSION = 371

but it don't change anything.

If someone could help me ?

Thanks.

I just tried myself and it works correctly on my firmware 5.00 (fat PSP)...
Are you sure your psp sdk is up to date? and that you replaced Brunni's oslib files with Sakya's ones?
Have you done a "clean" before your build (because main.o is in the archive!)?
Have you tried the EBOOT in the archive from Super Patrick, to be sure it's a compilation problem and not a problem on your console?
Apart from that, I don't see what could be wrong..

[Dr.Vince]

my pspsdk is up to date from this summer (most recent than OSLib MOD)
I have replaced the files but I will check this evening (just in case...)

I just take the source and gfx from the archive and make a clean before build
The EBOOT of the archive worked on my PSP

did you modfiy something in the makefile or not ?

Mine is from the exact same time as oslib mod (sakya gave it to me), so maybe it's that.

No I took it as is.

ok, it was that, I just replaced the include file but not the .a

so, now it works but I have some problem with memory.
What is the mean of this line ? and which value set ?

PSP_HEAP_SIZE_KB(12*1024);

What happens exactly? an error message? a freeze? you're still talking about the super patrick example or does this one totally works now and you moved on to a new project?

PSP_HEAP_SIZE_KB(12*1024);

This is the size of the heap you give to your application (heap = "tas" in french). I'm sure you know this but well: the heap is the memory used by mallocs or the new operator (dynamic allocation). you can also set the stack size (stack = "pile") with PSP_MAIN_THREAD_STACK_SIZE_KB. the stack is used to store everything allocated statically (int, bool, pointers, function calls...).
In my DJ Drops/Mega Drops games I set it like this:

PSP_HEAP_SIZE_KB(20480); //20*1024
PSP_MAIN_THREAD_STACK_SIZE_KB(512);

I'm not sure it's the best but it works, and those games are really big projects, and I use dynamic allocation as much as I can; depending on your coding style the stack may need to be bigger (but it's better to use dynamic allocations).

[Brunni]

20 MB heap + 0.5 MB stack should leave you around 3.5 MB for code. That's ok.
Is this instruction new in the PSPSDK? Because I never had to set the heap size, malloc automatically used all the memory available IIRC (something around 21 MB for small projects).

I'm not sure, I would have said no, it's not new, but when looking in my saves I found a reference only in february 2008. But I think you can omit those instructions and the default values will be used (really really not sure, needs to be checked).

[Dr.Vince]

it's not a very recent instruction, but I think it doesn't exist when you make oslib.

So, yes it's on another project.

PSP_HEAP_SIZE_KB(20480);

this don't work for me, I used instead PSP_HEAP_SIZE_MAX (by memory).

what do you mean exactly by for code ??

PSP_HEAP_SIZE_MAX on the other hand is very recent, I cannot use it my toolchain is too old.

I think he means the executable itself.

So, back to your problem Dr.Vince, it still doesn't work does it? you didn't explain what's happening exactly. If your project is not too big, post the code.

[Dr.Vince]

arf, sorry.

So I can't post it because my project is not too big but enormous !!

so the problem is that when I try to load big gfx, it tell me that he could not find the gfx, and in fact this message happens when he can't load in memory the gfx.

Size of my eboot is 6.5 Mo, so if for code correspond to that, it's normal that I can't use 20 Mo for the heap size
