苹果手机中的ObjectAL音频流？

Question

我在用objectAL传输PCM数据，

从我尝试或播放在线CGI流数据的示例代码中，

   ALSource *source = [[ALSource source] retain];

   ALBuffer *buffer = [[[OpenALManager sharedInstance] bufferFromUrl:[NSURL URLWithString:[[OpenALManager sharedInstance]bufferAsyncFromUrl:[NSURL URLWithString:@"someURL/somedata.cgi"] target:self selector:@selector(recievedBufferData:)]]] retain];

   source.position = alpoint(planet.position.x, planet.position.y, 0);
   source.referenceDistance = 50;
   [OpenALManager sharedInstance].currentContext.listener.position = alpoint(rocketShip.position.x, rocketShip.position.y, 0);

    self.isTouchEnabled = YES;
    [source play:buffer loop:YES];
}


-(void)recievedBufferData:(id)recievedData{
    NSLog(@"recieved");
}

我收到以下错误

OAL错误：-[OALAudioFile initWithUrl:reduceToMono:]：无法打开url某些url/soefile.cgi(错误代码0xffffffd5:未知ext音频错误)

但是recievedBufferData:方法只被调用一次

我无法播放.cgi文件，有谁能建议我如何在iphone中播放.cgi文件吗？

我也在尝试类似的方法，但还是解决不了。

我只是想问一下，我认为下面这行代码中有一些错误？

ALBuffer *buffer = [[[OpenALManager sharedInstance] bufferFromUrl:[NSURL URLWithString:[[OpenALManager sharedInstance]bufferAsyncFromUrl:[NSURL URLWithString:@"someURL/somedata.cgi"] target:self selector:@selector(recievedBufferData:)]]] retain];

你为什么打电话给bufferFromUrl和bufferAsyncFromUrl？

buffer = [[OpenALManager sharedInstance bufferFromFile:@"ColdFunk.caf"]保留]；ng
