0.Tip

1. 必须真机
2. 打包事项: 见文章底部

1.Setup

flutter_tencentplayer: ${last_version}

或

flutter_tencentplayer:
    git:
      url: https://github.com/qq326646683/flutter_tencentplayer.git

For Android

1. project/android/build.gradle 添加依赖的aar：

def flutterProjectRoot = rootProject.projectDir.parentFile.toPath()
def plugins = new Properties()
def pluginsFile = new File(flutterProjectRoot.toFile(), '.flutter-plugins')
if (pluginsFile.exists()) {
    pluginsFile.withReader('UTF-8') { reader -> plugins.load(reader) }
}

allprojects {
    repositories {
        google()
        jcenter()
        flatDir {
            dirs "${plugins.get("flutter_tencentplayer")}android/libs"
        }
    }
}

1. AndroidManifest.xml 声明权限:

<!--网络权限-->
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

<!--点播播放器悬浮窗权限-->
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />

<!--存储-->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

For Ios

//项目的info.plist文件上添加如下权限
<key>NSAppTransportSecurity</key>
	<dict>
		<key>NSAllowsArbitraryLoads</key>
		<true/>
  </dict>

2.Usage(TencentPlayer)

和video_player api相似,支持直播源,视频跳转,切换视频源,边下边播放,清晰度切换,设置播放速度。

1. 初始化播放器,支持asset、network、filePath、fileId四种方式播放

TencentPlayerController _controller;

_MyAppState() {
    listener = () {
      if (!mounted) {
        return;
      }
      setState(() {});
    };
}

initState() {
    _controller = TencentPlayerController.network('http://file.jinxianyun.com/testhaha.mp4', playerConfig: PlayerConfig())
    //_controller = TencentPlayerController.asset('static/tencent1.mp4')
    //_controller = TencentPlayerController.file('/storage/emulated/0/test.mp4')
    //_controller = TencentPlayerController.network(null, playerConfig: {auth: {"appId": 1252463788, "fileId": '4564972819220421305'}})
    ..initialize().then((_) {
        setState(() {});
      });
    _controller.addListener(listener);
}

2. 播放器配置参数

_controller = TencentPlayerController.network(url, playerConfig: PlayerConfig())

3. 播放器回调

Text("总时长：" + _controller.value.duration.toString())

4. 播放器事件

a. 跳转进度

_controller.seekTo(Duration(seconds: 5));

b. 设置播放速度

_controller.setRate(1.5); // 1.0 ~ 2.0

c. 切换播放源

controller?.removeListener(listener);
controller?.pause();
controller = TencentPlayerController.network(url, playerConfig: PlayerConfig(startTime: startTime ?? controller.value.position.inSeconds));
controller?.initialize().then((_) {
  if (mounted) setState(() {});
});
controller?.addListener(listener);

d. 切换清晰度(实质就是切换播放源)

3.Usage(Download)

离线下载, 支持断点续传(这里只支持m3u8视频、fileId), 支持多文件同时下载。

1. 初始化下载器

DownloadController _downloadController;

_MyAppState() {
    downloadListener = () {
      if (!mounted) {
        return;
      }
      setState(() {});
    };
}

initState() {
    _downloadController = DownloadController('/storage/emulated/0/tencentdownload', appId: 1252463788);
    _downloadController.addListener(downloadListener);
}

2. 下载事件

a. 下载

_downloadController.dowload("4564972819220421305", quanlity: 2);
// _downloadController.dowload("http://1253131631.vod2.myqcloud.com/26f327f9vodgzp1253131631/f4bdff799031868222924043041/playlist.m3u8");

b. 暂停下载

_downloadController.pauseDownload("4564972819220421305");
// _downloadController.stopDownload("http://1253131631.vod2.myqcloud.com/26f327f9vodgzp1253131631/f4bdff799031868222924043041/playlist.m3u8");

c. 取消下载

_downloadController.cancelDownload("4564972819220421305");
// _downloadController.cancelDownload("http://1253131631.vod2.myqcloud.com/26f327f9vodgzp1253131631/f4bdff799031868222924043041/playlist.m3u8");

3. 下载信息回调

因为支持多文件同时下载,回调以Map<String, DownloadValue>返回,key为url/fileId

5. 打包注意事项

1. flutter打包命令: flutter build apk --release
2. 混淆配置:

1. android/app/build.gradle

    buildTypes {
        release {
            ...
            // add
            ndk {
                abiFilters 'armeabi-v7a'
            }
            shrinkResources true
            minifyEnabled true
            useProguard true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

2.android/app/proguard-rules.pro没有该文件则新建
    -keep class com.tencent.** { *; }
