阿里云点播SDK集成(二)封装篇

1.上篇说到阿里云的文件上传以及注意的一些事项，今天就来说说简单的封装一下阿里云的播放器，简单说下思路（ps：在tableView或collectionView上用。为了节省资源以及滚动的流畅度，我们全局只用到1个播放器，提前加载视频并缓存本地，在滚动到当前视频的时候才去将播放器添加到cell上进行播放，滚动到下一个视频的时候会删除上一个播放器，网速好的情况下很流畅，其次也是看阿里云的视频解码速度 ）

2.封装播放组件api

// MARK:- 外部使用api extension PlayerManager {     /// 停止播放     func stop() {         player?.stop()         playerStatus_ = AVPStatusStopped         delegate?.playStatusChange(isPause: false)     }           /// 暂停     func pause() {         player?.pause()         playerStatus_ = AVPStatusPaused         delegate?.playStatusChange(isPause: true)     }           /// 恢复播放     func resume() {         player?.start()         playerStatus_ = AVPStatusStarted         delegate?.playStatusChange(isPause: false)     }           /// 播放指定索引的视频     func playAtIndex(index: Int, vid: String) {         progressView.setProgress(0, animated: false)         currentIndex = index         playSuperView.frame = vc.playerList(playerManager: self, frameForIndexAt: index)         player?.playerView.frame = playSuperView.bounds         let source = AVPVidStsSource()         source.vid = vid         source.region = STSManager.shared.region         source.securityToken = STSManager.shared.securityToken         source.accessKeySecret = STSManager.shared.accessKeySecret         source.accessKeyId = STSManager.shared.accessKeyId         self.player?.setStsSource(source)         self.player?.prepare()         if canPlay {             resume()         } else {             player?.pause()         }     }           /// 单击暂停或者播放     func singleTap() {         switch playerStatus_ {         case AVPStatusStarted:             pause()         default:             resume()         }     }           func removePlayView() {         playSuperView.removeFromSuperview()         playSuperView.isHidden = true         player?.stop()         currentIndex = -1     }           /// 移除某个video     func removeVideo(index: Int) {         currentIndex = -1     }           func updatePlayerStatus(withControllerStatus status: PlayerListControllerStatus) {         if status == .active {             canPlay = true         } else {             canPlay = false         }     }       }

3.根据代理设置监听，涉及到播放进度或者播放完成等一些事件可以在这里监听

extension VVPlayerManager: AVPDelegate {           func onError(_ player: AliPlayer!, errorModel: AVPErrorModel!) {         playerStatus_ = AVPStatusStopped         if errorModel.code.rawValue == 537198597 || errorModel.code.rawValue == 537067523 {             delegate?.playerManage(AuthorityExpired: self)         }         print("________playermanager________ 播放失败 => \(String(describing: errorModel.message))")         VVSTSManager.shared.updateSts()     }           func onPlayerEvent(_ player: AliPlayer!, eventType: AVPEventType) {         print("________playermanager________ \(eventType)")         switch eventType {         case AVPEventPrepareDone:             setPlayerscalingMode()         case AVPEventFirstRenderedStart:             playSuperView.isHidden = false         case AVPEventLoopingStart:             //一次完整视频播放完成             self.delegate?.aCompletePlaybackIsCompleted()         case AVPEventCompletion:             self.delegate?.playbackCompleted()         default:             break         }     }           func onPlayerStatusChanged(_ player: AliPlayer!, oldStatus: AVPStatus, newStatus: AVPStatus) {         playerStatus = newStatus     }           func onLoadingProgress(_ player: AliPlayer!, progress: Float) {               }           func onCurrentPositionUpdate(_ player: AliPlayer!, position: Int64) {         let duration: Float = Float(player.duration)         let position: Float = Float(position)         let current: Float = position / duration         self.delegate?.playChange(progressVaues: current, totalProgress: duration, currentProgress: position)     }       }
