配置信息： //by detu 1.控制使用软解还是硬解(改配置仅为建议，若设备无硬解能力，配置硬解走软解) 目前只在android端实现 type:OPT_CATEGORY_CODEC key:hw_decoder value:[true|false] 2.控制是否输出统计信息 time:2017-6-26 通用配置，不分平台 type:OPT_CATEGORY_PLAYER key:detu_show_statistics value:[true|false]
状态回调： ios:按照解码流程划分 1.FFP_MSG_VIDEO_DECODER_OPEN(图像解码器打开事件,此时可以通过IJKFFMoviePlayerController的_isVideoToolboxOpen判断是硬解还是软解) 1.key:@"IJKMPMoviePlayerVideoDecoderOpenNotification" userInfo:(IJKFFMoviePlayerController*) 2.FFP_MSG_VIDEO_SIZE_CHANGED 1.key:@"IJKMPMovieNaturalSizeAvailableNotification" userInfo:(IJKFFMoviePlayerController*) 3.FFP_MSG_SAR_CHANGED 1.key:@"IJKMPMovieNaturalSizeAvailableNotification" userInfo:(IJKFFMoviePlayerController*) 4.FFP_MSG_PREPARED（可以获取流元信息，通过_monitor.mediaMeta获取MediaMeta结构体） 1.key:@"IJKMPMediaPlaybackIsPreparedToPlayDidChangeNotification" userInfo:(IJKFFMoviePlayerController*) 2.key:@"IJKMPMoviePlayerLoadStateDidChangeNotification" userInfo:(IJKFFMoviePlayerController*) 5.FFP_MSG_BUFFERING_START(开始拉流缓存数据，可能会回调多次) 1.key:@"IJKMPMoviePlayerLoadStateDidChangeNotification" userInfo:(IJKFFMoviePlayerController*) 2.key:@"IJKMPMoviePlayerPlaybackStateDidChangeNotification" userInfo:(IJKFFMoviePlayerController*) 6.FFP_MSG_SEEK_COMPLETE(拖动进完成回调) 1.key:@"IJKMPMoviePlayerDidSeekCompleteNotification" userInfo: (int)seekMilliseconds 拖动进度毫秒值 (int)ret seek方法返回值，ret >=0 on success, error code otherwise
7.FFP_MSG_AUDIO_RENDERING_START(声音首帧播放事件) 1.key:@"IJKMPMoviePlayerFirstAudioFrameRenderedNotification" userInfo:(IJKFFMoviePlayerController*)
8.FFP_MSG_VIDEO_RENDERING_START(图像首帧渲染事件) 1.key:@"IJKMPMoviePlayerFirstVideoFrameRenderedNotification" userInfo:(IJKFFMoviePlayerController*)
9.FFP_MSG_DETU_STATISTICS_DATA(拉流统计事件，每秒回调一次，通过播放器配置"detu_show_statistics"控制开关) 1.key:@"IJKMPMoviePlayerDetuStatisticsNotification" userInfo:(NSDictionary *) 集合内容: 1.每秒接收码率值， key:@"detu_video_bitrate" value:Integer 2.每秒接收帧数，其中h264编码为B、P帧总和，mjpeg编码为全部I帧综合，key:@"detu_gop_size" value:Integer
10.FFP_MSG_BUFFERING_END（拉流完成，遇到错误可能会回调多次） 1.key:@"IJKMPMoviePlayerLoadStateDidChangeNotification" userInfo:(IJKFFMoviePlayerController*) 2.key:@"IJKMPMoviePlayerPlaybackStateDidChangeNotification" userInfo:(IJKFFMoviePlayerController*)
11.FFP_MSG_ERROR(错误回调) 1.key:@"IJKMPMoviePlayerPlaybackStateDidChangeNotification" userInfo:(IJKFFMoviePlayerController*) 2.key:@"IJKMPMoviePlayerPlaybackDidFinishNotification" userInfo:@{IJKMPMoviePlayerPlaybackDidFinishReasonUserInfoKey: @(IJKMPMovieFinishReasonPlaybackError), @"error": 错误ret} 这里的错误回调ret基本都是ijk拉流产生的ffmpeg函数错误，ijk不关心解码部分错误 12.FFP_MSG_PLAYBACK_STATE_CHANGED（各种状态回调） 1.key:@"IJKMPMoviePlayerPlaybackStateDidChangeNotification" userInfo:(IJKFFMoviePlayerController*) 这时候可以通过IJKFFMoviePlayerController->mp->mp_state获取当前播放器状态 其中:详情见ijkplayer.h #define MP_STATE_INITIALIZED 1 初始化完成 #define MP_STATE_ASYNC_PREPARING 2 开始prepare状态 #define MP_STATE_PREPARED 3 prepare状态 #define MP_STATE_PAUSED 5 暂停 #define MP_STATE_COMPLETED 6 完成
