[Vorbis-dev] Speed up?

[2spork at informatik.uni-hamburg.de]

Hello,

hope you're fine.
And hopefully someone can help me.
I wrote a short demonstration to show you my problem (see below). I'm 
asking always for 64 samples. When "ov_read_float()" is finished, I 
want to seek back to sample 1, and ask immediately for the next 64 
samples.
But when I run this small app, I get an totally high CPU load.

Is there a way to it speed up?
Or do I miss something?

Thanx,
Micha.


int _tmain(int argc, _TCHAR* argv[]){
	OggVorbis_File  vf;

	errno_t err;
	if ( (err = fopen_s( &oggaudio, "C:\\Test\\3.ogg" , "rb")) != 0){
		std::cout << "fopen problem" << std::endl;
	}

	if ( ov_open( oggaudio, &vf, NULL, 0 ) < 0 ){
		std::cout << "ov_open problem" << std::endl;
	}

	int read = 0;
	float** ovdata;
	int current_section = 0;

	do{
		read = ov_read_float(&vf , &ovdata, 64, &current_section);

		if ( read == 0 ){
			ov_pcm_seek( &vf, 0 );  // ov_raw_seek() won't help
			read = ov_read_float(&vf, &ovdata, 64, &current_section);
		}
	} while (read != 0);

	return 0;
}
