agora-flutter-sdk's Introduction

agora_rtc_engine

This Flutter plugin is a wrapper for Agora Video SDK

Agora.io provides building blocks for you to add real-time voice and video communications through a simple and powerful SDK. You can integrate the Agora SDK to enable real-time communications in your own application quickly.

NOTE: The main branch is major update base on the Agora Native SDK 4.x, which introduces some break changes. previous releases please see the following branches(the version < 6.0.0):

5.x

Usage

To use this plugin, please add agora_rtc_engine as a dependency to your pubspec.yaml file.

Getting Started

Get some basic and advanced examples from the example folder.

Privacy Permission

Agora Video SDK requires Camera and Microphone permission to start a video call.

Android

For the latest permission settings, please refer to the documentation at https://docs.agora.io/en/video-calling/get-started/get-started-sdk?platform=android#project-setup

See the required device permissions from the AndroidManifest.xml file.

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<!-- The Agora SDK requires Bluetooth permissions in case users are using Bluetooth devices. -->
<uses-permission android:name="android.permission.BLUETOOTH" />
<!-- For Android 12 and above devices, the following permission is also required. -->
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />

iOS & macOS

For the latest permission settings, please refer to the documentation at https://docs.agora.io/en/video-calling/get-started/get-started-sdk?platform=ios#project-setup

Open the Info.plist and add:

Privacy - Microphone Usage Description，and add some description into the Value column.
Privacy - Camera Usage Description, and add some description into the Value column.

Web (alpha)

The agora_rtc_engine for web is currently in alpha stage, and the documentation is incomplete and it has only been tested on desktop web at this time.

The agora_rtc_engine web is built on top of iris_web, a wrapper for the Agora Web SDK 4.x. This helps align the Native SDK (Android/iOS/macOS/Windows) APIs through the Agora Web SDK 4.x. Please note that the agora_rtc_engine web utilizes the Agora Web SDK 4.x underneath, so only a subset of the Native SDK APIs can be implemented on the web. If the APIs return AgoraRtcException with a -4 error code, this means these APIs are not supported at this time.

Download the iris_web(see the link below) artifact and include it as a <script /> tag in your <your-project>/web/index.html file. For example:

Project structure

<your-project>
|__web
   |__index.html
   |__iris-web-rtc_<x.y.z>.js

<!-- <your-project>/web/index.html -->
<!DOCTYPE html>
<html>
...
<body>
  ...
  <script src="iris-web-rtc_<x.y.z>.js"></script>
</body>
</html>

Download: https://download.agora.io/sdk/release/iris-web-rtc_n430_w4200_0.7.0.js

For Testing Purposes

You can directly depend on the Agora CDN for testing purposes:

<!-- <your-project>/web/index.html -->
<!DOCTYPE html>
<html>
...
<body>
  ...
  <script src="https://download.agora.io/sdk/release/iris-web-rtc_n430_w4200_0.7.0.js"></script>
</body>
</html>

Interact with Agora RTC Native SDK(Android/iOS only)

NOTE: This feature requires agora_rtc_engine >= 6.3.0

Due to performance constraints, direct implementation of advanced features like video and audio raw data processing is not currently feasible in Flutter side.

We enable you to create an RtcEngine within Flutter by utilizing the native handle from the RtcEngine(Android) or AgoraRtcEngineKit(iOS) of the Agora RTC Native SDK. This approach enables your application to directly utilize the advanced features of the Agora RTC Native SDK through the agora_rtc_engine package, bridging the gap between native capabilities and Flutter's environment.

More detail, please check the ProcessVideoRawData example for reference.

setLiveTranscoding - Casting alpha field from Integer to float error

When I call setLiveTranscoding, I'm hitting the following error:

E/MethodChannel#agora_rtc_engine( 7411): java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Float
E/MethodChannel#agora_rtc_engine( 7411):        at io.agora.agorartcengine.AgoraRtcEnginePlugin.onMethodCall(AgoraRtcEnginePlugin.java:568)

Particular line in question:
user.alpha = (float) optionUser.get("alpha");

Audience view when broadcasting from android device.

When you start a Broadcast view on android the Audience views are mirrored and zoomed in.

When using Broadcast views on IOS the audience views are mirrored but not zoomed in.

This looks like a bug as the views should be the same between devices when Broadcasting to an audience. And the views shouldn't change based on the device broadcast.

Edit: Upon further testing this bug happens when you stream from any device. Not just IOS.

Issue with hiding a video view.

When starting a call I am trying to have the current users camera view be placed in a small box in the corner of the screen (rather than the default of it taking up half the screen).

  Widget _miniView(List<Widget> views) {
    return Positioned(
        bottom: 120,
        right: 20,
        child: Container(
          child: views[0],
          width: 100,
          height: 100,
          decoration: BoxDecoration(
            borderRadius: BorderRadius.all(Radius.circular(25)),
          ),
        ));
  }

This works except when you attempt to hide the box (such as using a ternary to hide the positioned widget) it calls the event that hid it.

For example if i have a button that mutes the local video stream and then hides the miniView using a boolean it will call twice, once when i tap the button and then will automatically call the onTap function a second time after when the view is hidden.

This weird double call of buttons only happens when trying to hide a video view.

flutter build apk报错

VoIP Push Notification

Is it included in the project? I mean, is it possible to show ringing screen when user A is calling user B.. Like Messenger/Viber/WhatsUp?

Thx!

flutter调用native大部分接口没有执行result.success

Android实现大部分的接口没有调用result.success(null)来返回结果，并且dart端全部使用 async+await模式。这样导致如果在dart端调用AgoraRtcEngine方法时也使用协程会卡住无法继续执行，因为大部分接口返回的Future永远不会被执行。还有Android端result不需要包装，不管Android端在哪个线程调用result的方法都会在dart的主线程返回。

setLocalVideoMirrorMode?

I see a setLocalVideoMirrorMode function the Java API reference there doesn't seem to be a way to use it in the flutter plugin. Is there any plans to add this as functionality?

use voice call only?

hello
can i use this sdk to make voice calls only without video ?

android9.0音量键调节无效

android9.0系统，在音频直播场景下，通过音量键调节音量不生效，但是其他系统是正常的，需要开发者自己处理onKeyDown 事件吗？还是说有其他某些地方设置不对？

setLiveTranscoding - VideoCodecProfileType - Array of out bounds

In Android, when I use setLiveTranscoding, I'm hitting the below error:

E/MethodChannel#agora_rtc_engine( 6273): java.lang.ArrayIndexOutOfBoundsException: length=3; index=100
E/MethodChannel#agora_rtc_engine( 6273):        at io.agora.agorartcengine.AgoraRtcEnginePlugin.onMethodCall(AgoraRtcEnginePlugin.java:512)

The particular line which throws the error:
transcoding.videoCodecProfile = LiveTranscoding.VideoCodecProfileType.values()[(int) params.get("videoCodecProfile")];

The issue:
In Agora SDK, VideoCodecProfileType enum has the following members:
BASELINE =(66)
MAIN =(77)
HIGH =(100)

In the Agora Flutter SDK, when it's invoking setLiveTranscoding platform channel method, its resolving the VideoCodecProfileType enum to its int value.

Map<AgoraVideoCodecProfileType, int> _resolveVideoCodecProfileType = {
  AgoraVideoCodecProfileType.BaseLine: 66,
  AgoraVideoCodecProfileType.Main: 77,
  AgoraVideoCodecProfileType.High: 100
};

The particular line 512 is trying to resolve the int value back to the enum by using the ordinal of the enum, which causes the ArrayIndexOutOfBoundsException.

RtcStats "users" always null

Hi,

I'm trying to get the number of viewers of a Broadcast, is "users" from RtcStats the value that i need ?

If so, it seems to be always null, on the Broadcaster side as well as on the Audience side.

Here is the code i use :
void _addAgoraEventHandlers() { AgoraRtcEngine.onRtcStats = (RtcStats stats) { setState(() { viewers = stats.users; }); }; }

Then i display the viewers number in a Text widget.

Beside that, i encountered 0 problem using Agora it's a great platform !

Flutter怎么制作类似android悬浮窗最小化的功能

Flutter怎么制作类似android悬浮窗最小化的功能，在语音聊天，视频聊天，聊天室中退出界面，保持语音不断开，可以给点思路吗

Black Screen Issue

Only Black Screen when I copy-paste the code, but when I run the downloaded example, it's working fine

I tried both examples:

Steps I have done:

Downloaded Example from both repo & Updated APP_ID
Run flutter pub get & flutter run

It's working perfectly

But,

Created a few flutter project (Note: I'm using latest version of the flutter)
Copy the `lib' folder
Updated AndroidManifest.xml
Added permission & agora package to my pubspec.yaml & installed
Run

ONLY BLACK SCREEN & NO ERRORS ON CONSOLE ( I have tried https://github.com/AgoraIO-Community/Agora-Flutter-Quickstart#reporting-an-issue)

Note:
When I try to run your repo example & newly created example. I can see remote video working, but the local video is a black screen. which means your repo can capture the video and rendering. I think the issue here is capturing the video when we creating a new project

Need Agora RTC version 2.9.0 for x86_64 arch

Google is now restricting to publish app only if 64 bit code should be present along with 32bit code. For the native agora rtc version 2.8.0 there is no 'x86_64' code but v2.9.0 has. so please update the agora version so that in final build we will get 64bit code as well.

Provide a end to end video calling example.

Please provide a end to end video calling example where one device is used to call other device even when app is closed in the other device .

部分api还没有啊？

startAudioMixing这种比较常用的还没有支持吗？

关于Android使用TextureWidget和PlatformView的性能对比

作者您好:
看了您的视频，里面提到了TextureWidget和PlatformView的性能差别对比(闲鱼的外接纹理那篇文章也有提到过)，我在阅读了Android端相关的代码后，有一个困惑，希望您能解答一下：

Flutter Android端的桥接代码中 Texture 和 AndroidView都是通过TextureRegistray建立连接关系的，都会申请一个SurfaceTexture(建立BufferQueue通道)，然后基于此SurfaceTexture构造一个Surface。
不同之处只是外部将内容绘制到Surface的过程：Texture的话，用户负责将内容渲染到Surface上(比如OpenGL，将Surface作为ANativeWindow构造EGLSurface然后进行绘制)，而对于PlatformView来说，则是基于Surface构造一个VirtualDisplay，然后将用户的NativeView加入到该VirtualDisplay进行绘制，进而View的内容就绘制到该Surface。
我的困惑是，两者都通过Surface进行了桥接内容到Flutter, 而非直接Share OpenGLContext的方式来共享纹理进行绘制。那么理论上两者的性能消耗应该是差不多的。为什么您的测试结果中在Android上两者还出现了比较大的性能差距(也有可能您说的只是iOS的性能结果)？

dart端AgoraRtcEngine的事件回调不适合用静态变量

如题，客户端在集成声网时往往会实现一个client类用以管理音视频的各种操作和状态，其中包括AgoraRtcEngine的初始化和回调绑定。
在客户端使用音视频时会实例化client类，不使用时销毁client。
但是由于AgoraRtcEngine中的回调全部是静态变量，这就需要在client销毁时把AgoraRtcEngine绑定的回调全部置空以便client的内存可以被回收，显然这种操作非常不友好且容易被忽略。
如果有人直接在StatefulWidget中集成AgoraRtcEngine功能，极有可能导致State不会被释放。

setLiveTranscoding - AgoraLiveTranscoding.toJson bug

In /lib/src/base.dart, it looks like there is a bug in the following code:

Map<String, dynamic> toJson() => {
  'width': width,
  'height': height,
  'videoBitrate': videoBitrate,
  'videoFramerate': videoFramerate,
  'videoGop': videoGop,
  'videoCodecProfile': _resolveVideoCodecProfileType[videoCodecProfile],
  'transcodingUsers': transcodingUsers.map((item) => item.toJson()).toList(),
  'transcodingExtraInfo': transcodingExtraInfo,
  'watermark': watermark.toJson(),
  'backgroundImage': backgroundImage.toJson(),
  'audioSampleRate': _resolveAudioCodecProfileType[audioSampleRate],
  'audioBitrate': audioBitrate,
  'audioChannels': audioChannels,
  'backgroundColor': backgroundColor,
  'audioCodecProfile': _resolveAudioCodecProfileType[audioCodecProfile],
};

In particular this line:
'audioSampleRate': _resolveAudioCodecProfileType[audioSampleRate],

I'm guessing it should be using _resolveAudioSampleRate instead. However, take note that changing it to _resolveAudioSampleRate will cause the same issue as issue 41.

Problems with Flutter Build

I've been trying to integrate this with my Flutter project, but having some issues I hope is fixable. Simply by adding the dependency to my yaml, it adds 17MB to my apk size (doubling my project size) and when I try to run it on my Android 8 LG phone, it immediately crashes giving no errors. However, it does run on the Android 9 emulator for debug build, which is strange.
As a side note, for my app I only need the real-time voice features, not the video.. So it would be nice if there's a separate release of Agora Voice Engine for Flutter without the Video parts.... Thanks, hope I can get this functional soon since it's the last major feature of my app holding me back from release.

请在AgoraRtcEnginePlugin中暴露获取RtcEngine实例的静态方法

如题，我的产品中有屏幕共享需求，此前使用我自己写的声网插件，最近考虑切换到官方插件，但是拿不到实例，无法调用setVideoSource。
目前依赖声网RtcEngine.create的单例特性来获取实例，但是依然存在一些问题，因为原生这边监听不方便监听RtcEngine是否被销毁

setEnableSpeakerphone(true) doesnt work on ios devices

Im trying to get audio calls to use the speakerphone but the command to do so does nothing on ios devices.

AgoraRtcEngine.setEnableSpeakerphone(true);
AgoraRtcEngine.isSpeakerphoneEnabled().then((value) {
print(value); //This returns true but on ios it still uses the earpiece speaker.
});

onEvent error in Android implementation

Im getting the below error and not able to join the channel.

新增对arm64架构的支持

一周以前，Flutter官方发布了v1.7.8+hotfix.3，已经默认支持了ARM64，声网是否可以同步更新支持呢？

官方的原文描述如下：

From August 1st, 2019, Android apps that use native code and target Android 9 Pie will be required to provide a 64-bit version in addition to the 32-bit version when publishing to the Google Play Store. While Flutter has long supported generating 64-bit Android apps, version 1.7 adds support for creating Android App Bundles that target both 64-bit and 32-bit from a single submission. See the updated documentation on publishing Flutter-based Android apps to learn how to do this, as well as how to create separate APK files for both 32-bit and 64-bit devices.

中文社区的翻译如下：

从 2019 年 8 月 1 日开始，为了 target 到 Android Pie 版本，开发者们在 Google Play 上发布的应用必须支持 64 位架构。Flutter 一直都支持生成 64 位的 Android 应用，在 1.7 版本里，我们加入了对 Android App Bundles 的支持，开发者们可以在一次提交里同时 target 到 64 位和 32 位。可通过阅读这篇文档了解到如何分别生成 32 位和 64 位到应用等更多内容。

现在默认build会同时编译到两种CPU架构，加上agora_rtc_engine依赖项之后，会因为找不到libflutter.so 而报如下错误：

Gradle build failed to produce an Android package.

加上--target-platform android-arm 参数则正常编译出apk。

期待尽早修复～

如何解决Android设备上视频捕获不旋转问题？

Android设备上无论VideoEncoderConfiguration.orientationMode如何设置视频总是同一个方向，导致横屏模式和竖屏倒转设备时视频方向错误

Broadcast Video Black screen

I receive a black screen when trying to broadcast videos.

` VideoEncoderConfiguration _configuration = VideoEncoderConfiguration();

_handleCameraAndMicPermissions() async {
await PermissionHandler().requestPermissions([
PermissionGroup.camera,
PermissionGroup.microphone,
PermissionGroup.storage
]);
}

Future _initAgoraRtcEngine() async {
await AgoraRtcEngine.create(HBTV.API_KEY);
await AgoraRtcEngine.enableVideo();
await AgoraRtcEngine.setChannelProfile(ChannelProfile.LiveBroadcasting);
await AgoraRtcEngine.setClientRole(ClientRole.Broadcaster);
await AgoraRtcEngine.enableWebSdkInteroperability(true);
}

_eventHandlers() {
AgoraRtcEngine.onError = (error) {
print(error);
};

AgoraRtcEngine.onJoinChannelSuccess = (channel, uid, elapsed) {
  print('OnJoined: $channel, uid: $uid, time: $elapsed');
};

AgoraRtcEngine.onFirstRemoteVideoFrame = (uid, witdh, height, elapsed) {
  print('Uid: $uid, witdh: $witdh, height: $height, time: $elapsed');
};

}

Future init() async {
await _initAgoraRtcEngine();
_eventHandlers();
}

@OverRide
void initState() {
super.initState();
_handleCameraAndMicPermissions();
init();
}

@OverRide
void dispose() {
AgoraRtcEngine.leaveChannel().then((_) {
AgoraRtcEngine.destroy();
});
super.dispose();
}

@OverRide
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(),
body: Container(
child: Column(
children: [
Container(
height: MediaQuery.of(context).size.height - 100,
child: AgoraRtcEngine.createNativeView((viweId) {
AgoraRtcEngine.setupLocalVideo(viweId, VideoRenderMode.Fit);
_configuration.bitrate = 30;
_configuration.dimensions = MediaQuery.of(context).size;
_configuration.orientationMode =
VideoOutputOrientationMode.FixedPortrait;
AgoraRtcEngine.setVideoEncoderConfiguration(_configuration);
AgoraRtcEngine.joinChannel(null, 'flutter', null, 0);
AgoraRtcEngine.startPreview();
}),
),
],
),
),
);
}
}`

Release 打包APK错误

Debug版本没有问题，但是Release APK时抱错了：

What went wrong:
Execution failed for task ':agora_rtc_engine:verifyReleaseResources'.

远端视频进来后崩溃了

IOS crash when video call got greater than 2 join the channel

i just downloaded Agora-Flutter-Quickstart and test on IOS, IOS got crash immediately on iphone 6s when my android device joined the channel. The problem is if AgoraRenderWidget got 2 of more views it will crash when i replace AgoraRenderWidget to Container it worked fine.

Here is the last logs:

对比 Android与IOS缺少函数

isCameraExposurePositionSupported
setCameraExposurePosition
isCameraAutoFocusFaceModeSupported
setCameraAutoFocusFaceModeEnabled
isCameraFocusSupported
setCameraFocusPositionInPreview
以上函数在flutterSDK中都找不到
