CI Status Version Carthage compatible SPM supported License Platform

中文说明

SZAVPlayer is a lightweight audio/video player library, based on AVPlayer, pure-Swift. Support cache and video image output.

Features

  • ☑ Encapsulate the state changes of AVPlayer and AVPlayerItem and output them uniformly, greatly reducing the implementation cost of audio play.
  • ☑ Achieved full control of AVPlayer data loading, based on AVAssetResourceLoaderDelegate. Through the Range request and corresponding cache, it can respond to player's requests ASAP. It also can play the cached audio normally in the weak network and no network enviroment.
  • ☑ Support video image output, can be drawn to multiple views at the same time.
  • ☑ Load AVAsset asynchronously to not blocking the main thread.
  • ☑ Support setting cache size munually and also support cleaning.

Hint

If you find that always play failed in the simulator, try exit simulator completely and restart again. This is kind of simulator's bug.

Usage

  1. Create player and set delegate.

    let player = SZAVPlayer()
    player.delegate = self
    
    audioPlayer = player
    
  2. Setup player with url.

    // uniqueID is to identify wether they are the same audio. If set to nil will use urlStr to create one.
    let config = SZAVPlayerConfig(urlStr: audio.url, uniqueID: nil)
    audioPlayer.setupPlayer(config: config)
    
    // If you want play video, pass an additional parameter `isVideo`.
    let config = SZAVPlayerConfig(urlStr: video.url, uniqueID: nil, isVideo: true, isVideoOutputEnabled: true/false)
    videoPlayer.setupPlayer(config: config)
    
  3. Implement SZAVPlayerDelegate.

    extension AudioViewController: SZAVPlayerDelegate {
    
        func avplayer(_ avplayer: SZAVPlayer, refreshed currentTime: Float64, loadedTime: Float64, totalTime: Float64) {
            progressView.update(currentTime: currentTime, totalTime: totalTime)
        }
    
        func avplayer(_ avplayer: SZAVPlayer, didChanged status: SZAVPlayerStatus) {
            switch status {
            case .readyToPlay:
                SZLogInfo("ready to play")
                if playerStatus == .playing {
                    audioPlayer.play()
                }
            case .playEnd:
                SZLogInfo("play end")
                handlePlayEnd()
            case .loading:
                SZLogInfo("loading")
            case .loadingFailed:
                SZLogInfo("loading failed")
            case .bufferBegin:
                SZLogInfo("buffer begin")
            case .bufferEnd:
                SZLogInfo("buffer end")
                if playerStatus == .stalled {
                    audioPlayer.play()
                }
            case .playbackStalled:
                SZLogInfo("playback stalled")
                playerStatus = .stalled
            }
        }
    
        func avplayer(_ avplayer: SZAVPlayer, didReceived remoteCommand: SZAVPlayerRemoteCommand) -> Bool {
            return false
        }
    
    }
    
  4. Replace new audio.

    // The setupPlayer function will automatically determine if it has been setup before. 
    // If it is, it will directly call the replacePalyerItem function to replace the new audio.
    audioPlayer.setupPlayer(config: config)
    

    or

    // or just use this function.
    audioPlayer.replace(urlStr: audio.url, uniqueID: nil)
    

    these two functions have the same effect.

  5. Enable video image output.

    • Set isVideoOutputEnabled to true.
    let config = SZAVPlayerConfig(urlStr: video.url, uniqueID: nil, isVideo: true, isVideoOutputEnabled: true)
    videoPlayer.setupPlayer(config: config)
    
    • Implement avplayer delegate function.
    func avplayer(_ avplayer: SZAVPlayer, didOutput videoImage: CGImage) {
        videoOutputView1.layer.contents = videoImage
    }
    
    • Call removeVideoOutput function when ready to release the player.
    videoPlayer.removeVideoOutput()
    
  6. Seek player to time.

    audioPlayer.seekPlayerToTime(time: currentTime, completion: nil)
    
  7. Set max cache size.

    // Unit: MB, if reached the max size, it will automatically trim the cache.
    SZAVPlayerCache.shared.setup(maxCacheSize: 100)
    
  8. Clean all cache.

    SZAVPlayerCache.shared.cleanCache()
    

Example

The Example project has implemented a complete play example, including play/pause/previous/next/seekToTime/cleanCache, etc.

To run the example project, clone the repo, and run pod install from the Example directory first.

Requirements

  • iOS 10.0+
  • Swift 5.0+

Installation

CocoaPods

SZAVPlayer is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'SZAVPlayer'

Carthage

Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To integrate SZAVPlayer into your Xcode project using Carthage, specify it in your Cartfile:

github "eroscai/SZAVPlayer" ~> 1.1.1

Swift Package Manager

From Xcode 11, you can use Swift Package Manager to add SZAVPlayer to your project.

  • Select File > Swift Packages > Add Package Dependency. Enter https://github.com/eroscai/SZAVPlayer.git in the "Choose Package Repository" dialog.
  • Add CoreServices.framework and AVFoundation.framework to your project if not added before. (If anyone knows how to do this automatically, please tell me).
