Aliyun Player With Flutter

flutter_aliplayer #

A new flutter plugin project , The project supports Android and iOS base on AliyunPlayerSDK Android SDK URL iOS SDK URL

Installation #

dependencies:
  flutter_aliplayer: ^{{latest version}}

说明 #

flutter 播放器在原生层是基于 Android 播放器 SDK 和 iOS 播放器 SDK 的。可能部分原生播放器 SDK 的接口有遗漏,在 flutter 播放器插件中没有暴露出来。目前我们已将源码提供出来,开发者可以自行添加。也可以通知给我们,我们会对遗漏的接口进行补充。

AliPlayer #

1. 播放控制 #

  ///1、创建播放器
  FlutterAliplayer fAliplayer = FlutterAliPlayerFactory.createAliPlayer();
  ///多实例播放器创建方式,需要 flutter 层管理 playerId,其他接口一样,在播放器的回调中会返回对应的 playerId 来通知 flutter 层是哪一个播放器对象
  //FlutterAliplayer fAliplayer = FlutterAliPlayerFactory.createAliPlayer(playerId: playerId);

  ///2、设置监听,只列举了部分接口,更多接口可以参考播放器 Android\iOS 接口文档
  ///准备成功
  fAliplayer.setOnPrepared((playerId) {});
  ///首帧显示
  fAliplayer.setOnRenderingStart((playerId) {});
  ///视频宽高变化
  fAliplayer.setOnVideoSizeChanged((width, height,playerId) {});
  ///播放器状态变化
  fAliplayer.setOnStateChanged((newState,playerId) {});
  ///加载状态
  fAliplayer.setOnLoadingStatusListener(
      loadingBegin: (playerId) {},
      loadingProgress: (percent, netSpeed,playerId) {},
      loadingEnd: (playerId) {});
  ///拖动完成
  fAliplayer.setOnSeekComplete((playerId) {});
  ///播放器事件信息回调,包括 buffer、当前播放进度 等等信息,根据 infoCode 来判断,对应 FlutterAvpdef.infoCode
  fAliplayer.setOnInfo((infoCode, extraValue, extraMsg,playerId) {});
  ///播放完成
  fAliplayer.setOnCompletion((playerId) {});
  ///设置流准备完成
  fAliplayer.setOnTrackReady((playerId) {});
  ///截图结果
  fAliplayer.setOnSnapShot((path,playerId) {});
  ///错误结果
  fAliplayer.setOnError((errorCode, errorExtra, errorMsg,playerId) {});
  ///切换流变化
  fAliplayer.setOnTrackChanged((value,playerId) {});

  ///3、设置渲染的 View
  @override
  Widget build(BuildContext context) {
    var x = 0.0;
    var y = 0.0;
    Orientation orientation = MediaQuery.of(context).orientation;
    var width = MediaQuery.of(context).size.width;

    var height;
    if (orientation == Orientation.portrait) {
      height = width * 9.0 / 16.0;
    } else {
      height = MediaQuery.of(context).size.height;
    }
    AliPlayerView aliPlayerView = AliPlayerView(
        onCreated: onViewPlayerCreated,
        x: x,

            ],
          ),
        );
      },
    );
  }

    ///4、设置播放源
    ///说明:STS 播放方式,vid、region、accessKeyId、accessKeySecret、securityToken 为必填,其他参数可选
    ///     AUTH 播放方式,vid、region、playAuth 为必填,其他参数可选
    /// 每个 Map 对应的key 在 flutter 的 Demo 的 config.dart 中查看,fAliplayer 为播放器对象,如果还未创建,参考后续文档创建播放器

        break;
      default:
    }
  }

  ///可选步骤:开启自动播放,默认关闭
  fAliplayer.setAutoPlay(true);
  ///5、prepare
  fAliplayer.prepare();
  ///说明:如果开启了自动播放,则调用 prepare 后即可,播放器在 prepare 成功后会自动播放,如果未开启自动播放,则需要在 setOnPrepard() 准备成功回调中,调用 fAliplayer.play() 开始播放

//暂停播放
///暂停播放后,恢复播放直接调用 play 即可
fAliplayer.pause();

//停止播放
///停止播放后,恢复播放需要重新走一遍播放流程:prepare --> play
fAliplayer.stop();

//销毁
fAliplayer.release();

//seek
///seekMode 可选值:FlutterAvpdef.ACCURATE(精准seek) 和 FlutterAvpdef.INACCURATE(非精准seek)
fAliplayer.seek(position,seekMode);

//循环播放
fAliplayer.setLoop(true);

//静音、音量控制
fAliplayer.setMute(true);
///设置播放器音量,范围0~1.
fAliPlayer.setVolume(1);

//倍速播放
///可选值:0.5,1.0,1.5,2.0
fAliplayer.setRate(1.0);

//切换多码率,自动码率切换
///在prepare成功之后,通过getMediaInfo可以获取到各个码流的信息,即TrackInfo
fAliplayer.getMediaInfo().then((value) {
//value 为 map,value['tracks'] 可以获取对应的 TrackInfos 列表信息,可以参考 Demo 中 AVPMediaInfo info = AVPMediaInfo.fromJson(value); 如何解析 TrackInfo
};
///在播放过程中,可以通过调用播放器的selectTrack方法切换播放的码流,参数为 TrackInfo 中的 trackIndex,切换的结果会在OnTrackChangedListener监听之后会回调
fAliplayer.selectTrack(index);
  
///自动码率切换
fAliplayer.selectTrack(-1);

//画面旋转、填充、镜像操作
//设置画面的镜像模式:水平镜像,垂直镜像,无镜像。
fAliplayer.setMirrorMode(FlutterAvpdef.AVP_MIRRORMODE_NONE);
//设置画面旋转模式:旋转0度,90度,180度,270度
fAliplayer.setRotateMode(FlutterAvpdef.AVP_ROTATE_0);
//设置画面缩放模式:宽高比填充,宽高比适应,拉伸填充
fAliplayer.setScalingMode(FlutterAvpdef.AVP_SCALINGMODE_SCALETOFILL);

2. 边播边缓存 #

需要在 prepare 之前设置给播放器

var map = {
  "mMaxSizeMB": _mMaxSizeMBController.text,///缓存目录的最大占用空间
  "mMaxDurationS": _mMaxDurationSController.text,///设置能够缓存的单个文件的最大时长
  "mDir": _mDirController.text,///缓存目录
  "mEnable": mEnableCacheConfig,///是否开启缓存功能
};
fAliplayer.setCacheConfig(map);

3. 播放器其他配置 #

需要在 prepare 之前设置给播放器

var configMap = {
  'mStartBufferDuration':_mStartBufferDurationController.text,///起播缓冲区时长
  'mHighBufferDuratio':_mHighBufferDurationController.text,///高缓冲时长
  'mMaxBufferDuration':_mMaxBufferDurationController.text,///最大缓冲区时长
  'mMaxDelayTime': _mMaxDelayTimeController.text,///最大延迟。注意:直播有效
  'mNetworkTimeout': _mNetworkTimeoutController.text,///网络超时时间
  'mNetworkRetryCount':_mNetworkRetryCountController.text,///网络重试次数
  'mMaxProbeSize': _mMaxProbeSizeController.text,///最大probe大小
  'mReferrer': _mReferrerController.text,///referrer
  'mHttpProxy': _mHttpProxyController.text,///http代理
  'mEnableSEI': mEnableSEI,///是否启用SEI
  'mClearFrameWhenStop': !mShowFrameWhenStop,///停止后是否清空画面
  'mDisableVideo': mDisableVideo,///禁用Video
  'mDisableAudio': mDisableAudio///禁用Audio
};
widget.fAliplayer.setConfig(configMap);

AliListPlayer #

//1.创建列表播放器
FlutterAliListPlayer fAliListPlayer = FlutterAliPlayerFactory.createAliListPlayer();

//2.添加资源、移除资源。列表播放器目前只支持两种播放方式,URL 和 STS    
///uid是视频的唯一标志。用于区分视频是否一样。如果uid一样,则认为是一样的
fAliListPlayer.addUrlSource(url,uid);
fAliListPlayer.addVidSource(vid,uid);
fAliListPlayer.removeSource(uid);

//设置预加载个数
fAliListPlayer.setPreloadCount(count);

//播放视频源
///uid 为必填项,如果是 URL 播放方式,只需要 uid 即可,如果是 STS 方式,则需要填写 STS 信息
fAliListPlayer.moveTo();

AliLiveShiftPlayer #

//创建直播时移播放器
FlutterAliLiveShiftPlayer _flutterAliLiveShiftPlayer = FlutterAliPlayerFactory.createAliLiveShiftPlayer();

//设置渲染 View
@override
  Widget build(BuildContext context) {
    var x = 0.0;
    var y = 0.0;

        width: width,
        height: height);
    return Scaffold(
      appBar: AppBar(
        title: const Text('Plugin for LiveShiftPlayer'),
      ),
      body: Column(children: [
        Container(
          width: width,
          height: height,
          child: aliPlayerView,
        ),
      ]),
    );
  }

///setPlayerView(viewId) 给播放器设置渲染 View
///setDataSource(timelineUrl,url) 设置播放源,其中 url 为播放地址,timelineurl 为时移请求地址
void onViewPlayerCreated(int viewId) {
    this._flutterAliLiveShiftPlayer.setPlayerView(viewId);
    int time = (new DateTime.now().millisecondsSinceEpoch / 1000).round();
    var timeLineUrl =
        "$_timeLineUrl&lhs_start_unix_s_0=${time - 5 * 60}&lhs_end_unix_s_0=${time + 5 * 60}";
    _flutterAliLiveShiftPlayer.setDataSource(timeLineUrl, _url);
  }
}

///时移到某个时间
_flutterAliLiveShiftPlayer.seekToLiveTime();

///获取当前直播的播放时间
flutterAliLiveShiftPlayer.getCurrentTime().then((value) {});

///获取当前直播的现实时间
_flutterAliLiveShiftPlayer.getCurrentLiveTime().then((value) {});

///准备
_flutterAliLiveShiftPlayer.prepare();

///开始播放
_flutterAliLiveShiftPlayer.play();

///停止
_flutterAliLiveShiftPlayer?.stop();
///销毁
_flutterAliLiveShiftPlayer?.destroy();

///时移seek完成通知。playerTime:实际播放的时间
_flutterAliLiveShiftPlayer.setOnSeekLiveCompletion(playTime, playerId) {});

//时移时间更新监听事件。currentTime - 当前现实时间,shiftStartTime - 可时移的起始时间,shiftEndTime - 可时移的结束时间
_flutterAliLiveShiftPlayer.setOnTimeShiftUpdater((currentTime, shiftStartTime, shiftEndTime, playerId) {});

下载 #

可选步骤,如果是安全下载,需要配置自己的加密校验文件到 SDK 中,普通下载则不需要

//配置加密校验文件,尽可能提前配置(可选)  
FlutterAliPlayerFactory.initService(byteData);

//创建下载器
FlutterAliDownloader donwloader = FlutterAliDownloader.init();
///设置保存路径
donwloader.setSaveDir(path)

//开始下载
///1.prepare
///参数说明:type 可选值为 FlutterAvpdef.DOWNLOADTYPE_STS / FlutterAvpdef.DOWNLOADTYPE_AUTH 。当 type 为 DOWNLOADTYPE_STS 时候,必填参数为: {vid,accessKeyId,accessKeySecret,securityToken},当 type 为 DOWNLOADTYPE_AUTH 时,必须填参数为 {vid,playAuth}
  downloader.prepare(type, vid).then((value) {
      //value 为 map,对应 Demo 中的 DownloadModel 自定义下载类
      DownloadModel downloadModel = DownloadModel.fromJson(value);
      //2.selectItem,根据不同的 trackInfo 来确定需要下载哪个清晰度
      List<TrackInfoModel> trackInfos = downloadModel.trackInfos;
      downloader.selectItem(vid,trackInfos[0].index);
      //3.start
      downloader.start(vid, trackInfos[0].index).listen((event) {
        //说明:event 可能会有多种信息,可参考 FlutterAvpdef.EventChanneldef 中的信息,以下为具体说明:
        if (event[EventChanneldef.TYPE_KEY] == EventChanneldef.DOWNLOAD_PROGRESS){
            //下载进度百分比信息,获取下载进度百分比:event[EventChanneldef.DOWNLOAD_PROGRESS]
        }else if(event[EventChanneldef.TYPE_KEY] == EventChanneldef.DOWNLOAD_PROCESS){
            //处理进度百分比信息,获取处理进度百分比:event[EventChanneldef.DOWNLOAD_PROCESS]
        }else if(event[EventChanneldef.TYPE_KEY] == EventChanneldef.DOWNLOAD_COMPLETION){
            //下载完成,可以通过 event['vid']、event['index'] 获取对应的 vid 和 index 用于判断是哪个视频下载完成,event['savePath'] 用于获取下载完成视频的本地路径
        }else if(event[EventChanneldef.TYPE_KEY] == EventChanneldef.DOWNLOAD_ERROR){
            //下载失败,可以通过 event['vid']、event['index'] 获取对应的 vid 和 index 用于判断是哪个视频下载失败,event['errorCode']、event['errorMsg'] 可以获取对应的错误码,和错误信息
        }
      });
  });

//停止下载、删除和释放
downloader.stop(vid, index)
//可以删除下载的本地文件
downloader.delete(vid, index)
downloader.release(vid, index)

加载 RtsSDK #

如果需要支持 artc 协议,首先需要引入如下两个插件:

//flutter_aliplayer_artc: 对应版本号
//flutter_aliplayer_rts: 对应版本号

Android 在build.gradle中添加依赖即可

dependencies{
    implementation 'com.aliyun.sdk.android:AlivcArtc:$version'
    implementation 'com.aliyun.rts.android:RtsSDK:$version'
}

iOS在Podfile文件中添加依赖即可

target 'Runner' do
  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))

  pod 'AliPlayerSDK_iOS_ARTC', '$version'  #$version比如5.4.9.1
  pod 'RtsSDK', '$version'  #$version比如2.5.0

end

Android 需要额外调用如下代码(尽可能提前):

FlutterAliPlayerFactory.loadRtsLibrary();
