Streaming StreamingKit
Overview

StreamingKit

StreamingKit (formally Audjustable) is an audio playback and streaming library for iOS and Mac OSX. StreamingKit uses CoreAudio to decompress and playback audio (using hardware or software codecs) whilst providing a clean and simple object-oriented API.

The primary motivation of this project was to decouple the input data sources from the actual player logic in order to allow advanced customizable input handling such as HTTP progressive download based streaming, encryption/decryption, auto-recovery, dynamic-buffering. StreamingKit is the only streaming and playback library that supports dead-easy gapless playback between audio files of differing formats.

Main Features

  • Free OSS.
  • Simple API.
  • Easy to read source.
  • Carefully multi-threaded to provide a responsive API that won't block your UI thread nor starve the audio buffers.
  • Buffered and gapless playback between all format types.
  • Easy to implement audio data sources (Local, HTTP, AutoRecoveringHTTP DataSources are provided).
  • Easy to extend DataSource to support adaptive buffering, encryption, etc.
  • Optimised for low CPU/battery usage (0% - 1% CPU usage when streaming).
  • Optimised for linear data sources. Random access sources are required only for seeking.
  • StreamingKit 0.2.0 uses the AudioUnit API rather than the slower AudioQueues API which allows real-time interception of the raw PCM data for features such as level metering, EQ, etc.
  • Power metering
  • Inbuilt equalizer/EQ (iOS 5.0 and above, OSX 10.9 Mavericks and above) with support for dynamically changing/enabling/disabling EQ while playing.
  • Example apps for iOS and Mac OSX provided.

Installation

StreamingKit is available as a Cocoapod. You can also simply copy all the source files located inside StreamingKit/StreamingKit/* into your Xcode project.

Example

There are two main classes. The STKDataSource class which is the abstract base class for the various compressed audio data sources. The STKAudioPlayer class manages and renders audio from a queue DataSources. By default STKAudioPlayer will automatically parse URLs and create the appropriate data source internally.

Play an MP3 over HTTP

STKAudioPlayer* audioPlayer = [[STKAudioPlayer alloc] init];

[audioPlayer play:@"http://www.abstractpath.com/files/audiosamples/sample.mp3"];

Gapless playback

STKAudioPlayer* audioPlayer = [[STKAudioPlayer alloc] init];

[audioPlayer queue:@"http://www.abstractpath.com/files/audiosamples/sample.mp3"];
[audioPlayer queue:@"http://www.abstractpath.com/files/audiosamples/airplane.aac"];

Intercept PCM data just before its played

[audioPlayer appendFrameFilterWithName:@"MyCustomFilter" block:^(UInt32 channelsPerFrame, UInt32 bytesPerFrame, UInt32 frameCount, void* frames)
{
   ...
}];

    I'm building AudjustableTest from the command line like this:

    xcodebuild -workspace AudjustableTest.xcworkspace -scheme AudjustableTest

    I have no clue what's going on. Building from Xcode works, the float.h header is imported just fine, but building from command line fails..

  • AUGraphStop crashes right after stream ending (iOS 14 only bug)

    AUGraphStop crashes right after stream ending (iOS 14 only bug)

    While adopting my app to new iOS 14, I faced a bug that StreamingKit crashes at stopAudioUnitWithReason method in status = AUGraphStop(audioGraph) line. This happens only after music file ends playing, with reason == STKAudioPlayerStopReasonEof. Frequency of crash = 100%.
    Also, no description of this problem was provided by Xcode.

    How can this be fixed? This is a very serious issue.

  • Difference between progress and duration when player stops

    Difference between progress and duration when player stops

    Hi,

    Me again :)

    I'm queuing a remote track right before the completion of the playing track is it transitions nicely.

    However for some files/tracks this doesn't work because the player stops even though the next track is queued up. This happens consistently with a few particular tracks.

    So I added a log when didFinishPlayingQueueItemId is captured and noticed this

    Finished playing 2 - reason: 0 - progress 139.891365 - duration 139.908802

    It basically stops playing before the duration.

    What can cause this? Or what can cause the track not not transition to the next? Thanks!!

  • Weird bleeps and no metadata available when playing a SHOUTcast stream

    Weird bleeps and no metadata available when playing a SHOUTcast stream

    When playing a SHOUTcast stream there are random bleeps occuring every x seconds and song metadata is not available. This happens for e.g. with: http://23.237.150.98:8512/ (PRM Internet Radio) http://lin1.san.fast-serv.com:9844/ (ANDYS 80S)

    When playing those URL's with for e.g. Apple Music or VLC it plays without any bleeps and the currently played song is displayed.

    Hello, maybe this is a silly question, but I have a problem with the lock screen.

    lock screen in the pause button is presented, when I press the player is stopped, but the icon is still pause, internally paused the player using the pause method of the library but the icon does not change.

    Cannot play the audio in background - iOS 11 - using it in SWIFT

    Hello team,

    First of all thank you for making an awesome library. Appreciate all the team. I am using this library in one of the application, where as soon as the device got updated to iOS 11, it stopped playing the audio in the background and also not showing in controlcenter.

    Did anybody faced such issue ?

    Thanks In Advance.

  • Playing audio from Documents directory

    Playing audio from Documents directory

    Hi there...StreamingKit did help me a lot while streaming an audio from the server. I could also play a local audio, stored in a resource bundle with my player. However, I have been facing some issues when I try to play audio that I have stored in my app's document directory. Unfortunately, the player neither shows any error nor does it play the audio. Any help regarding the issue would be helpful. Thanks in advance.

    Many users of the app I'm working on having this crash. Initially I though that this issue is the same as #350, but stacktrace is different.

    I attached stacktrace:

    Some things I want to highlight:

    I didn't have a chance to see full analytics yet. And I could not reproduce this crash. But from the stacktrace I see that this happens after STKAudioPlayer receives audio packets.

    I will further investigate this issue. Any tips or thoughts will be very helpful.

    AUGraphStart crashes on simulator below iOS 14

    Both the example app and our app crashes under simulator below iOS 14 (so only iOS 14 simulator works) since Big Sur.

    It seems that once they fixed to avoid crashing on iOS 14 #453 it started to crash on the simulators. There is also a Thread on Apple forums https://developer.apple.com/forums/thread/667921
