0.Tip

1. 必须真机
2. android打release包必须加--no-shrink： flutter build apk --release --no-shrink

1.Setup

flutter_tencentplayer: ${last_version}

or

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"
        }
    }
}

2. 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())

Prop	Type	Default	Note
autoPlay	bool	true	是否自动播放
loop	bool	false	是否循环播放
headers	Map<String, String>		请求头
cachePath	String		缓存路径(边播放边下载)
progressInterval	int	1	播放进度回调频率(秒)
startTime	int	0	哪里开始播放(秒)
auth	Map<String, dynamic>		云点播视频源appId&fileId
supportBackground	bool	false	是否后台播放

3. (播放器回调)

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

Prop	Type	Note
initialized	bool	是否初始化完成从而显示播放器
aspectRatio	double	用来控制播放器宽高比
duration	Duration	时长
position	Duration	播放进度
playable	Duration	缓冲进度
isPlaying	bool	是否在播放
size	Size	视频宽高
isLoading	bool	是否在加载
netSpeed	int	视频播放网速
rate	double	播放速度
bitrateIndex	int	视频清晰度
orientation	int	手机旋转角度(android only)
degree	int	本地file视频自带旋转属性
eventCode	int	事件监听code

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");

b. 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

Prop	Type	Note
downloadStatus	String	"start"、"progress"、"stop"、"complete"、"error"
quanlity	int	1: "FLU"、2: "SD"、3: "HD"、4: "FHD"、5: "2K"、6: "4K"
duration	int
size	int	文件大小
downloadSize	int	已下载大小
progress	int	已下载大小
playPath	String	下载文件的绝对路径
isStop	bool	是否暂停下载
url	String	下载的视频链接
fileId	String	下载的视频FileId
error	String	下载的错误信息
