Pmf Viewer

[mowglisanu]

The other day I wanted to watch some cut-scenes from a game(of course I didn't want to play the game), so I so i fired up google and searched for a pmf player. To my shock and horror I couldn't find any, so I decided to make one, and here it is.

Pmf Viewer allows you to browse the drives available on you psp(that I knew of) and view
pmf video files.

You can also browse images(iso and cso) and view the videos they contain.
This is based on the m33 sdk so may only work on m33 cfw.

Tested on 5.00 m33-6 phat

Controls
UP - Move up
DOWN - Move down
X/START - Select/Play
SQUARE - Pause
CIRCLE - Stop
TRIANGLE - Back
LTRIGGER - Slow down
RTRIGGER - Speed up
SELECT - Credits

If the is sufficient interest I might make a full 1.0 version

Could you upload your source code for this?

[mowglisanu]

Its just pmfplayer10 with some mods and a file browser.
What about it you want to know?

[kenkai]

How'd you do it without a prx file like pmfplayer10 used?

[mowglisanu]

It is opensource, it containd a class CPMFPlayer, which is basically all you need.
I have it in one of my shared folders, check one of my posts in source code repository section, I think the file name is pmfplayer10.zip

ok. I was also having some other problems that we talked about awhile ago in this post

http://www.psp-programming.com/forums/index.php/topic,5052.0.html

did u manage to solve them in your pmf viewer?

[mowglisanu]

I didn't use relative paths,

To use relative path, your thread has to have a cwd.
libc sets the cwd for your main thread, but you'll have to set it for any thread you create.

could you send me your code? I think it would help me understand better because i didn't understand very much of your last post lol

Code: (pmfplayer/main.cpp)

/*
 * PMF Player Module
 * Copyright (c) 2006 by Sorin P. C. <magik@hypermagik.com>

#include <pspkernel.h>

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

#include "pmfplayer.h"

PSP_MODULE_INFO(pmfPlayer, 0, 1, 1);

int main_thread(SceSize _argc, void* _argp)
{

CPMFPlayer *MpegDecoder = new CPMFPlayer();

if(MpegDecoder->Initialize() < 0)
{
pspDebugScreenInit();
pspDebugScreenPrintf(MpegDecoder->GetLastError());
sceKernelDelayThread(5000000);
return -1;
}

if(MpegDecoder->Load((char*)_argp) < 0)
{
pspDebugScreenInit();
pspDebugScreenPrintf(MpegDecoder->GetLastError());
sceKernelDelayThread(5000000);
return -1;
}

if(MpegDecoder->Play() < 0)
{
pspDebugScreenInit();
pspDebugScreenPrintf(MpegDecoder->GetLastError());
sceKernelDelayThread(5000000);
return -1;
}

MpegDecoder->Shutdown();

return 0;
}

extern "C" int module_start(SceSize _argc, char* _argp)
{
char* arg = _argp + strlen(_argp) + 1;

SceUID T = sceKernelCreateThread("pmfplayer_thread", main_thread, 0x20, 0xFA0, THREAD_ATTR_USER, NULL);

sceKernelStartThread(T, strlen(arg)+1, arg);

sceKernelWaitThreadEnd(T, 0);

return 0;
}

Notice the sceKernelCreateThread in module start
This thread T, has no Current working directory which is necessary for the use of relative paths such as ./video.pmf.
So either use full paths of set a current working directory for T

ok, is there any way to change it so it could work with ./file.pmf?

and are you able to exit back to the xmb when a video is playing? I havent tested out your player yet so i dont know if you fixed all my problems

[mowglisanu]

ok, is there any way to change it so it could work with ./file.pmf?

1. Don't instanciate CPMFPlayer and call CPMFPlayer::Load  in a new thread
or
2. Set a current working directory for the thread.

Also I stop the player before exiting, CPMFPlayer creates multiple threads and semaphore, unexpected termination may result in indefinite waits.
