Hi
There is some library got updated in OpenGL so with x code 6 it is not compiling the source.
please check got resolved soon.

)

It would be great to have the option to pass a URL to a local file.
Writing apps supporting On and offline mode would be great this way.

既然你已经提供了DOUAudioStreamerRemoveCacheOnDeallocation这个option，那么第二播放的时候是否就可以直接播放本地的呢？

it will be very perfect for me if support cocoapods, Thanks

The app crashes when the phone calls end with the "failed to get interruption type" NSAssert message. I believe this is because of the AudioSession APIs being deprecated in iOS 7. Is there a quick fix for this or will there be a update soon expected?

这个连接你试试。我用你的demo都返回error
http://182.140.147.34/a1260.phobos.apple.com/us/r1000/013/Music6/v4/42/60/7d/42607df8-95e9-fed3-1a22-4356cf71f0e8/mzaf_2013381517535870742.plus.aac.p.m4a

不过，以前一直可以放itunes的音乐的。我用的是itunes api搜索回来的音乐，然后用你的streamer播放的。但是现在不行了。

实际是21:25
但是DOUAudioStreamer中的duration只有12:10
使用iOS sdk中的 avplayer也是获取的短了。

不知道是什么原因导致的？

如题 这个是什么愿意呢！

目前在做一个视频播放器，音频部分是AAC格式的数据，想请问一下是否可以使用DouAudioStreamer来播放NSData,而不是播放一个音频文件，如果可以的话，麻烦告知一下方法，不胜感激！

I wonder there is a way to get buffered data progress?
Thanks!

使用AVPlayer可以播放，但是DOUAudioStreamer却无法播放

Great project - thanks for making this! I know you are planning to release documentation, but what is the protocol for adding files to the local music library? The demo project crashes when you select "Local Music Library" because there is nothing in the musicLibraryTracks array.

崩溃停在了DOUAudioEventLoop.m文件的- (BOOL)_handleEvent:(event_type)event withStreamer:(DOUAudioStreamer **)streamer方法中的:
NSAssert(status == noErr, @"failed to activate audio session");
这个断言失败，status 不等于noErr， 打印出来了failed to activate audio session

允许用户拖动播放进度条，调整audiofile的播放进度
看了一下代码，加这个功能并不是很容易，貌似你不打算支持这个功能？

URL is: http://64.20.42.58:8036, it's always buffering, and received zero byte. While I tried VLC, it works fine.

为什么缓冲进度都百分之50了但是移动到百分之50前都还是要等待，不能直接播放，可否解决一下

Not really an issue - just a question:

I'm supporting both local files and streaming, and the custom visualizer I built relies on the "averagePowerForChannel" method from the AVAudioPlayer to update my metering (for local files). Obviously it's not this simple when streaming, but I'm having trouble finding a way to get a range of values from the streamer to use for output metering. Any range of values will do, and the mapping to dB values shouldn't be an issue.

If anyone has any thoughts on getting an output level range they would be greatly appreciated, and I think this could help bridge the gap for local players and streamers when using custom visualizers.

Thanks

像这样的

This crash occurred on either iOS7 or iOS6

DOUEAGLView.m line 154
-[DOUEAGLView _displayLinkCallback:]

Hdnmrifjnhgsfjdnhggsoqihhrjdjejnh

分别是 opengles 和 QuartzCore

编译成功运行时 依旧会Crash

//后台播放音频设置
AVAudioSession *session = [AVAudioSession sharedInstance];
[session setActive:YES error:nil];
[session setCategory:AVAudioSessionCategoryPlayback error:nil];

//让app支持接受远程控制事件
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];

无效

目测是贵厂内部使用的包管理系统？

我使用以下方法没用：

UInt32 audioRouteOverride = !isSpeaker ? kAudioSessionOverrideAudioRoute_None:kAudioSessionOverrideAudioRoute_Speaker;
AudioSessionSetProperty(kAudioSessionProperty_OverrideAudioRoute, sizeof(audioRouteOverride), &audioRouteOverride);
AVAudioSession *audioSession = [AVAudioSession sharedInstance];
[audioSession setActive:YES error:nil];

Hi, want to say thanks for this great project, hope it will continue growing!
It works well, but found one annoying bug:
when DOUAudioStreamer object starts playing track and at the same moment you receive a call, or start another music application and play audio, it will log an error: "ERROR: [com.douban.audio-streamer.event-loop] 1207: AUIOClient_StartIO failed (560557684)" and will enter to undefined state, it will not respond to any action: play,pause, stop or reset.

不支持AAC或者M4A等压缩音频格式。我们在做一个关于录音的APP，音频进行过了压缩成AAC编码，导致无法正常播放。

Issue: After I start streaming a music from server, I paused music on my app. I locked the device by pressing power button. Once again I logged-in into system after entering my passcode and tried to start music streaming again. But it is throwing error DOUAudioStreamerError. I'm able to see this same issue in sample app DOUASDemo.

This issue occurs only when I lock and unlock the device. Otherwise it is working fine. Normally application should continue streaming from where it left after I unlock the device.

Do we have any workaround for this? I guess this issue should be resolved.

how can i show audio track in control center, when track is playing. and how can i handle event from control center(play/pause,next,previous)? thanks)

只看见在下载.

Hi guys,

This method

• (DOUAudioDecoderStatus)decodeOnce
  in the DOUAudioDecoder.m

I found sometimes this method return DOUAudioDecoderEndEncountered, but the audio just buffer.

DOUAudioDecoder.m
Line 386:
if (ioOutputDataPackets == 0) {
[_lpcm setEnd:YES];
pthread_mutex_unlock(&_decodingContext.mutex);
return DOUAudioDecoderEndEncountered;
}

Why the ioOutputDataPackets == 0, but audio just buffer?

Thank you.

我在测试aac音频在线播放时，遇到了如上问题，但是播放mp3文件是没有问题的。
我发现，播放aac文件时，在DOUAudioPlaybackItem类中，
status = AudioFileGetProperty(_fileID, kAudioFilePropertyEstimatedDuration, &size, &estimatedDuration);
计算的播放时长不是整个音频文件的，而是当前已下载的文件的时间长度。
不知道有没有办法能够像mp3那样，虽然文件只下载了一部分，也能够获取正确的时长，并且完整的播放完成。

Hello Douban,

After, following your instructions to add the source files src into my application, i am getting below error,

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_DOUMPMediaLibraryAssetLoader", referenced from:
      objc-class-ref in DOUAudioFileProvider.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

IDE : XCode 6.0
SDK : iOS 8.0

Researched lot about this. No solution yet. Do i need to import any frameworks or libs for this?

Nice audio streamer man, but how i can seek to time with change streamer range for playing from new position without waiting caching previous data. Sorry for my broken english. =)

如题。

PCM not supported?

你好！
在使用的过程中，我发现，当播放的音频文件非常短时，会导致程序崩溃，经过跟踪我发现了问题所在：
文件： DOUAuidoPlaybackItem.m
问题代码块：

static OSStatus audio_file_read(void *inClientData,
SInt64 inPosition,
UInt32 requestCount,
void *buffer,
UInt32 *actualCount)
{
__unsafe_unretained DOUAudioPlaybackItem *item = (__bridge DOUAudioPlaybackItem *)inClientData;
if ([item filePreprocessor] == nil) {
memcpy(buffer, (uint8_t *)[[item mappedData] bytes] + inPosition, requestCount);
}
else {
NSData *input = [NSData dataWithBytesNoCopy:(uint8_t *)[[item mappedData] bytes] + inPosition
length:requestCount
freeWhenDone:NO];
NSData *output = [[item filePreprocessor] handleData:input offset:inPosition];
memcpy(buffer, [output bytes], [output length]);
}
*actualCount = requestCount;
return noErr;
}

memcpy(buffer, (uint8_t *)[[item mappedData] bytes] + inPosition, requestCount);这段代码未考虑溢出的问题。
增加如下判断就可以了：
NSInteger len =[item mappedData].length；
if (requestCount > len) {
requestCount = len - inPosition;
}

如果有播放进度 修改 这个功能就更完美了.

I find this framework cache the remote audio file when play, but why i play next with remote url, it couldn't play from cached audio file instead of playing from remote url.

This would cause UI display issue: a temporary paused status -_-

在网络不稳定的情况下有时候下载进度已经到一半了
但是状态还是处于缓冲状态,无法播放出来.

RT?

When I try to stream remote mp3 audio, this library works perfectly -- The audio buffers and then starts playing as the rest of the file loads ahead of it; However, when I try to stream m4a (aac) files, it won't start playing until it loads the entire file.

Edit:
Interestingly, small m4a files stream fine. This issue only occurs with large m4as (I was testing with 10 minutes of audio -- 14.8MB). Similarly large mp3s stream perfectly.

我目前是通过循环来判断是否下载完成的.

When moving source data or example into a different project app crashes every time song starts. It just throughs exception in following line:

OSStatus status = AudioConverterNew(&inputFormat, &_outputFormat, &_audioConverter);

when _createAudioConverter method is called.

Update 1: Only appears when streaming (with not local items).

从百度分享那里取来的下载链接,如下:
http://pan.baidu.com/share/link?shareid=533818&uk=2032859066

然后右键拷贝出来具体文件的下载地址.就像这样的地址:

http://d.pcs.baidu.com/file/2d9cad8a977bdd5ffc05282aa9ca3cce?fid=2032859066-250528-2190128000&time=1369982858&sign=FDTAR-DCb740ccc5511e5e8fedcff06b081203-L0%2F3dQiS2BDMaH%2BglFbDqrj1AcQ%3D&rt=sh&expires=8h&r=811992230&sh=1&response-cache-control=private

但是通过DOUAudioStreamer 读取 会报解码错误. 无法播放

但是后台依旧正在在下载这个文件.

或者像这样的音频下载地址:

有时候成功,有时候失败,这是为什么....
