Problems with sf::SoundBuffer

[CBenni::O]

Hy,

Why doesn't this code work:

Code: [Select]

int main()
{
sf::SoundBuffer MSB;
MSB.LoadFromFile("nice_music.ogg");
sf::Sound MySound2(MSB);
MySound2.Play();
if(MySound2.GetStatus() != sf::Sound::Playing)
{
// Debugging shows that this spot is executed...
}
sf::Sleep(10.0f);
return 0;
};
I am using the SFML 2.0 from the trunk...

Is it because I dont create a Window, or why else?

Does LoadFromFile("nice_music.ogg") succeed?

[CBenni::O]

Now it does... And the status is set correctly, too...

But still, I don't hear the sound...

EDIT: I put this piece of code into a working piece of code, which creates a window, and still, it didn't play!
EDIT2: Sry, i am an idiot It wasn't a soft- but a hardwareproblem :roll:

:? another Problem... in a bigger program, it loads the SoundBuffer all right, but when i call it using my ResourceManager, it can't play the soundbuffer anymore... I haven't found a place where a soundbuffer is copied, only sf::SoundBuffer* pointers are passed to the user... What ist the problem here?

see EDIT above...

sry for confusing posts...

Show your code

[CBenni::O]

I'll try to make it as small as possible...

So, these are the important parts:

Creating the Resource:

Code: [Select]

SoundBuffer_Resource* NewSoundBuffer = new SoundBuffer_Resource(TopJob.filename);
ResourcePair = std::make_pair(TopJob.filename,NewSoundBuffer);
MyResources.insert(ResourcePair);
(topjob is a job out of the loading queue...)
Loading the Buffer:

Code: [Select]

SoundBuffer_Resource::SoundBuffer_Resource(const std::string filename)
{
MySoundBuffer = new sf::SoundBuffer();
MySoundBuffer->LoadFromFile(filename);
}

Aquiring the Resource:

Code: [Select]

template<typename T>
T* BBB::ResourceManager::Acquire(std::string name, DWORD maxloadingtime, DWORD sleeptime)
{
DWORD StartTime = timeGetTime();
while(MyResources.find(name) == MyResources.end() || MyResources.find(name)->second == NULL)
{
DWORD eltime = timeGetTime()-StartTime;
if(eltime < maxloadingtime)
{
Sleep(sleeptime);
}
else
{
return NULL;
}
}

}

return static_cast<T*>(MyResources.find(name)->second);
};

Using the SoundBuffer:

Code: [Select]

BBB::SoundBuffer_Resource* MyRes2 = MyResMgr.Acquire<BBB::SoundBuffer_Resource>("../Data/nice_music.ogg",1000000,10);
if(MyRes2 != NULL)
{
MySoundIsLoaded = true;
sf::SoundBuffer test = *MyRes2->Get();
MySound.SetBuffer(*MyRes2->Get());
MySound.Play();
}

I don't see a single copy in there...

The Buffer returned by Aquire ist not NULL, but it isn't played either...

You still don't check whether LoadFromFile succeeds or not.

[CBenni::O]

I test it, i just put that out, because it is quite a lot of testing etc.

I have added this into the constructor of SoundBuffer_Resource:

Code: [Select]

sf::Sound test(*MySoundBuffer);
test.play();
Sleep(10000);

And it played the sound! (only for 10 seconds, of course )

Sorry for multiple Post,
but I have tested some more and found out that inside of SoundBuffer_Resource::Get(), the buffer is okay... So the problem is somewhere in the way from Get() to the usage uf my Buffer...

does anyone see the error I'm making?

Or is it (eventually) a bug in the copy semantics? But actually, I don't pass Instances, only pointers...

If I were you, I'd write a minimal example that reproduces this problem. Your code is too complex and contains too many lines unrelated to the problem, you'll waste more time trying to debug it directly than writing a simpler similar code.

[CBenni::O]

I've been trying that, but I never achieved to build a code that reproduces my Problem... I am not able to isolate the Problem...

I'll try again, or else I upload the complete source, if that helps...

It works now...

I didn't get what was wrong, but this worked:

Code: [Select]

sf::Sound* MySound;

if(!MySoundIsLoaded)
{
BBB::SoundBuffer_Resource* MyRes2 = MyResMgr.Acquire<BBB::SoundBuffer_Resource>("../Data/nice_music.ogg",false,BBB::Res_None,0,0);
if(MyRes2 != NULL)
{
MySound = new sf::Sound(*MyRes2->Get()));
MySound->Play();
MySoundIsLoaded = true;
}
}

But this didn't:

Code: [Select]

sf::Sound* MySound = new sf::Sound();

if(!MySoundIsLoaded)
{
BBB::SoundBuffer_Resource* MyRes2 = MyResMgr.Acquire<BBB::SoundBuffer_Resource>("../Data/nice_music.ogg",false,BBB::Res_None,0,0);
if(MyRes2 != NULL)
{
MySound->SetBuffer(*MyRes2->Get()));
MySound->Play();
MySoundIsLoaded = true;
}
Any mistakes left?

I would check the semantics of SetBuffer...

[Laurent]

Your second piece of code is totally wrong, can you show the actual code?

[CBenni::O]

I'm sorry... did a few mistakes -.-

Correcting them rightaway...
