#pragma mark 通知
IJKMPMediaPlaybackIsPreparedToPlayDidChangeNotification; // 播放状态的改变 代替 MPMoviePlayerContentPreloadDidFinishNotification
IJKMPMoviePlayerScalingModeDidChangeNotification; // 缩放比例的改变
IJKMPMoviePlayerPlaybackDidFinishNotification;
IJKMPMoviePlayerPlaybackDidFinishReasonUserInfoKey; // NSNumber (IJKMPMovieFinishReason)
当电影播放结束或用户退出播放时调用。
IJKMPMoviePlayerPlaybackStateDidChangeNotification; // 用户改变播放状态改变时调用
IJKMPMoviePlayerLoadStateDidChangeNotification; // 当网络加载状态发生变化时。
IJKMPMoviePlayerIsAirPlayVideoActiveDidChangeNotification; // 当视频通过 AirPlay 开始播放视频或结束时调用
Movie Property Notifications
属性相关的同时声明
IJKMPMovieNaturalSizeAvailableNotification; // 在执行 prepareToPlay 时开始异步确定影片属性,当相关属性变为有效可用时调用该通知
IJKMPMoviePlayerVideoDecoderOpenNotification; // 视频 编译器打开通知
