I am trying to stream sound over a socket. I am using the FMOD SoundSystem libraries to play the music. I am not expecting people to know FMOD, but maybe you guys could still help me out a bit. I can set up FMOD to stream the file when playing it, I just have to figure out how I can send the data through the socket in chucks and have FMOD playing the chunks while its doing the transferring.

I have the file sending through the socket in chunks working:

(Toggle Plain Text)

// receiving end
char buf[1000] = "";
int n = 0;
std:: ofstream outFile("test.mp3", std::ios::binary);
while ((n = recv(socket, buf, sizeof(buf), 0)) > 0)
{
	outFile.write(buf, n);
}
outFile.close();

So I guess I need to get FMOD to play the sound while this is happening. I think the biggest problem is how do I get them both using the same file, because if the file is open while its receiving the data through the socket, then FMOD will not be able to open the file to play the music.

FMOD code to stream a file and play it:

(Toggle Plain Text)

FMOD::System* system = 0;
FMOD_RESULT fres = FMOD::System_Create(&system);
fres = system->init(4, FMOD_INIT_NORMAL, 0);
FMOD::Sound* sound = 0;
fres = system->createStream("test.mp3", FMOD_CREATESTREAM, 0, &sound);
FMOD::Channel* channel = 0;
// there would be code here to set the stream buffer size accordingly.
fres = system->playSound(FMOD_CHANNEL_FREE, sound, false, &channel);

Any help at all on how to tackle this would be great.
