Additional platform/OS support from the other community

• flutter-tizen: https://github.com/flutter-tizen/plugins/tree/master/packages/flutter_webrtc
• flutter-elinux(WIP): sony/flutter-elinux-plugins#7

Add flutter_webrtc as a dependency in your pubspec.yaml file.

iOS

Add the following entry to your Info.plist file, located in <project root>/ios/Runner/Info.plist:

<key>NSCameraUsageDescription</key>
<string>$(PRODUCT_NAME) Camera Usage!</string>
<key>NSMicrophoneUsageDescription</key>
<string>$(PRODUCT_NAME) Microphone Usage!</string>

This entry allows your app to access camera and microphone.

Note for iOS.

The WebRTC.xframework compiled after the m104 release no longer supports iOS arm devices, so need to add the config.build_settings['ONLY_ACTIVE_ARCH'] = 'YES' to your ios/Podfile in your project

ios/Podfile

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
     target.build_configurations.each do |config|
      # Workaround for https://github.com/flutter/flutter/issues/64502
      config.build_settings['ONLY_ACTIVE_ARCH'] = 'YES' # <= this line
     end
  end
end

Android

Ensure the following permission is present in your Android Manifest file, located in <project root>/android/app/src/main/AndroidManifest.xml:

<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />

If you need to use a Bluetooth device, please add:

<uses-permission android:name="android.permission.BLUETOOTH" android:maxSdkVersion="30" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" android:maxSdkVersion="30" />

The Flutter project template adds it, so it may already be there.

Also you will need to set your build settings to Java 8, because official WebRTC jar now uses static methods in EglBase interface. Just add this to your app level build.gradle:

android {
    //...
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

If necessary, in the same build.gradle you will need to increase minSdkVersion of defaultConfig up to 23 (currently default Flutter generator set it to 16).

Important reminder

When you compile the release apk, you need to add the following operations, Setup Proguard Rules

flutter-webrtc's Issues

MissingPluginException

Hi again,
I'm trying to use RTCPeerConnection,

var peerConnection = RTCPeerConnection("{'iceServers': []}");

problem is, just add this line show an error message on flutter :

Another exception was thrown: MissingPluginException(No implementation found for method listen on channel cloudwebrtc.com/WebRTC/peerConnectoinEvent{'iceServers': []})

Anything wrong?

Cant get SessionDescription to work on another JavaScript Side

I try to build a Electron Application but I cant parse the Session Description or the RemoteDescription.
'DOMException: Failed to execute 'setRemoteDescription' on 'RTCPeerConnection': Failed to parse SessionDescription.'

Code:
var sdp = { "type": data.descriptiontype, "description": data.descriptionsdp };
console.log(sdp)
peerConnection.setRemoteDescription(sdp)

Support Data Channel

Implement data channel and sample.

[WIP]Support for Flutter Desktop

Texture widget for the embedder seems to be coming soon: google/flutter-desktop-embedding#107 (comment), let's port it to the desktop embedder and let the plugin extend to mac/linux/windows. 😄

Release Mode, In real cell phone generated has stopped when I try to run the application

Hi, I'm making a video conference app using the webrtc plugin for flutter, at the end of the application and make the release compiles perfectly but does not work on the real cell phone. I thought it was my implementation but, I built a new application, compile to release and it works. I think the problem is with the webrtc plugin, any suggestion to solve the problem ?

Cant access Camera

I try to get the MediaStream from the Camera with:
`navigator.getUserMedia(mediaConstraints).then((stream) {
_localRenderer.srcObject = stream;
});

final Map<String, dynamic> mediaConstraints = {
"video": true,
"optional": []
}`

I tried the MediaConstraints from the demo and everything and even tried navigator.getSources() but even there is a error. Im using this on a Epson Moverio BT-300 could that be the error, but there is android installed by default, so it should work.

And sadly get the Error:
nable to getUserMedia: Failed to create new track E/flutter ( 4168): #0 navigator.getUserMedia (package:flutter_webrtc/get_user_media.dart:20:7) E/flutter ( 4168): <asynchronous suspension> E/flutter ( 4168): #1 _HomePageState.getContent.<anonymous closure> (package:remoteworker/pages/HomePage.dart:246:25) E/flutter ( 4168): #2 _InkResponseState._handleTap (package:flutter/src/material/ink_well.dart:507:14) E/flutter ( 4168): #3 _InkResponseState.build.<anonymous closure> (package:flutter/src/material/ink_well.dart:562:30) E/flutter ( 4168): #4 GestureRecognizer.invokeCallback (package:flutter/src/gestures/recognizer.dart:102:24) E/flutter ( 4168): #5 TapGestureRecognizer._checkUp (package:flutter/src/gestures/tap.dart:242:9) E/flutter ( 4168): #6 TapGestureRecognizer.handlePrimaryPointer (package:flutter/src/gestures/tap.dart:175:7) E/flutter ( 4168): #7 PrimaryPointerGestureRecognizer.handleEvent (package:flutter/src/gestures/recognizer.dart:315:9) E/flutter ( 4168): #8 PointerRouter._dispatch (package:flutter/src/gestures/pointer_router.dart:73:12) E/flutter ( 4168): #9 PointerRouter.route (package:flutter/src/gestures/pointer_router.dart:101:11) E/flutter ( 4168): #10 _WidgetsFlutterBinding&BindingBase&GestureBinding.handleEvent (package:flutter/src/gestures/binding.dart:180:19) E/flutter ( 4168): #11 _WidgetsFlutterBinding&BindingBase&GestureBinding.dispatchEvent (package:flutter/src/gestures/binding.dart:158:22) E/flutter ( 4168): #12 _WidgetsFlutterBinding&BindingBase&GestureBinding._handlePointerEvent (package:flutter/src/gestures/binding.dart:138:7) E/flutter ( 4168): #13 _WidgetsFlutterBinding&BindingBase&GestureBinding._flushPointerEventQueue (package:flutter/src/gestures/binding.dart:101:7) E/flutter ( 4168): #14 _WidgetsFlutterBinding&BindingBase&GestureBinding._handlePointerDataPacket (package:flutter/src/gestures/binding.dart:85:7) E/flutter ( 4168): #15 _invoke1 (dart:ui/hooks.dart:168:13) E/flutter ( 4168): #16 _dispatchPointerDataPacket (dart:ui/hooks.dart:122:5)

P2P not working on s7 edge

When connecting any device to s7 edge clients gets connected but no video output occurs on either sides. Data channels pretty much the same, connected->no output. Tried emulators real devices, android pairs, android/ios pairs. Flutter doctor all good.

Would appreciate any advice since iam lost on this case. What can prevent device from showing video?

By the way, when testing api on loopback it works fine and loops video without problems..

Ambiguous facing mode config (different for iOS and Android)

Following code enables rear camera on iOS but still uses front camera on Android

  final Map<String, dynamic> mediaConstraints = {
      'audio': true,
      'video': {
        'mandatory': {
          'minWidth': '1280',
          'minHeight': '720',
          'minFrameRate': '24'
        }
      },
      'facingMode': 'environment',
      'optional': []
    };
    _localStream = await navigator.getUserMedia(mediaConstraints);

Tested on Samsung Galaxy S8+ with Oreo 8.0 and on OnePlus 5T with custom rom 9.0

Update WebRTC framework

Currently I'm trying to update WebRTC
Goal is to make this plugin easily updatable with rolling dependency version
I've removed WebRTC.framework in root, and using CocoaPods dependency (just set s.dependency 'GoogleWebRTC' in podspec)
However I'm stuck at updating FlutterRTCMediaStream.m

Following code not working

    if (videoDevice) {
        RTCVideoSource *videoSource = [self.peerConnectionFactory videoSource];
        
        // FIXME The effort above to find a videoDevice value which satisfies the
        // specified constraints was pretty much wasted. Salvage facingMode for
        // starters because it is kind of a common and hence important feature on
        // a mobile device.
        
        RTCCameraVideoCapturer *capt = [[RTCCameraVideoCapturer alloc] initWithDelegate:videoSource];
        AVCaptureDeviceFormat *selectedFormat = nil;
        int currentDiff = INT_MAX;
        int targetWidth = 1280;
        int targetHeight = 720;
        for (AVCaptureDeviceFormat *format in [RTCCameraVideoCapturer supportedFormatsForDevice:videoDevice]) {
            CMVideoDimensions dimension = CMVideoFormatDescriptionGetDimensions(format.formatDescription);
            FourCharCode pixelFormat = CMFormatDescriptionGetMediaSubType(format.formatDescription);
            int diff = abs(targetWidth - dimension.width) + abs(targetHeight - dimension.height);
            if (diff < currentDiff) {
                selectedFormat = format;
                currentDiff = diff;
            } else if (diff == currentDiff && pixelFormat == [capt preferredOutputPixelFormat]) {
                selectedFormat = format;
            }
        }
        //NSLog(@"test %@", [(NSString *)selectedFormat lowercaseString]);
        if (selectedFormat == nil) {
            NSLog(@"Capture format fucked up. Fallback");
            selectedFormat = [RTCCameraVideoCapturer supportedFormatsForDevice:videoDevice].firstObject;
        }

        // source, fail with a new OverconstrainedError.
        errorCallback(@"OverconstrainedError", /* errorMessage */ nil);

UnsatisfiedLinkError

Hello,
While trying out your example app I have ran into a problem. On Android i get the UnsatisfiedLinkError
whole stacktrace:

The app works great on iOS, but I cant get around this on Android. Every suggestion would help.

After a little while of leaving the app open, I see this error.

minSDK version error

After I add flutter webrtc plugin to pubspec.yaml

dependencies:
  flutter:

    flutter_webrtc: ^0.0.1

I'm getting error

It is build on Android Emulator. Not tested on Ios yet.
How to change minSdk on flutter?
Can somebody help me solve this?

CAMERA not working in simulator

I am using the latest GIT version of flutter-webrtc plugin. Followed the documentation to install the plugin and tried running the plugin in an app I am writing. The app is running in a simulator. It looks like the camera does not work. In the simulator on a Mac OS machine, I see a dark screen (for the main screen) and a multi-colored pixelated mini screen. Looks like a bug to me.

Does flutter-webrtc work with iOS and Android simulators? These simulators are an essential part of development using Flutter

iOS: The plugin is incompatible with use_frameworks in Podfile

Some Flutter plugins require to add use_frameworks! directive to Podfile. In my case, I need to use Crashlytics, which requires use_frameworks!. To reproduce the issue, add use_frameworks! to the Podfile of the example project and run pod install. It will produce the following:

$ pod install

Welcome to Awesome Flutter

Your package is great, Thank you !
https://github.com/Solido/awesome-flutter

请问一下WebRTC.framework用的webrtc哪个版本？

Publish to pub.dartlang.org

I notice this package is not published to pub.dartlang.org.

Is there a reason it hasn't been published?

thanks!

Something is hanging in the memory after the completion of the video call

After the completion of the call, the following message appears in the log at intervals of a second or two:

My Dispose method:

@override
  void dispose() {
    if (_localStream != null) {
      if (_peerConnection != null)
        _peerConnection.removeStream(_localStream);
      _localStream.dispose().then((value){
        _localStream = null;
      });
    }
    super.dispose();
    print("+++ CallScreen Dispose +++");
  }

What did I forget?

Widget Capture

Thank you for awesome library.

Any possibilities implement to send widget's video.

RTCSessionDescription.sdp String length 3414,is there any way to make it shorter?

MediaRecorder implementation for iOS

I can barely read Objective-C code, so help wanted)

how' it going here :) ?

anything other than a README?

Server

Could you add the server code link ?
Easier to test

Switch audio output from phone audio to speaker audio.

Hi,

I have greatly appreciated this framework. Thank you.

I'm wondering if anyone would know how to switch the audio output to speakerphone instead of phone audio; currently, during a video chat, the audio from the video is played through the phone's ear speaker and not through the main speaker or the 'speakerphone.'

I think this would be a necessary functionality for video calls on mobile.

Master branch android build error

Missing method maybeRequestPermissionsOnHostResume implementation in master branch:

Screen Capture

Hey, Thanks for the plugin.

This issue is about implementing Screen Capture, I did notice it is on the todo list and there is already a bit of implementation with MediaProjection on android side, can you let us know the status if its ready to use

Backend server

Can you tell me the backend and codecs ?

Thanks for this great GUI

FAILURE - build and deploy to iOS

• Added flutter_webrtc to the pubpsec.yaml

RTCVideoView might have a bug

between send offer success and unreceived target answer,I show _localRander full screen

new Stack(children: <Widget>[
  new Positioned(
	  left: 0.0,
	  right: 0.0,
	  top: 0.0,
	  bottom: 0.0,
	  child: new Container(
		margin: new EdgeInsets.fromLTRB(0.0, 0.0, 0.0, 0.0),
		width: MediaQuery.of(context).size.width,
		height: MediaQuery.of(context).size.height,
		child: new RTCVideoView(_localRenderer),
		decoration: new BoxDecoration(color: Colors.black54),
	  )),
	])

it work well.

when I receive target answer, I want show _remoteRenderer full screen.

new Stack(children: <Widget>[
                  new Positioned(
                      left: 0.0,
                      right: 0.0,
                      top: 0.0,
                      bottom: 0.0,
                      child: new Container(
                        margin: new EdgeInsets.fromLTRB(0.0, 0.0, 0.0, 0.0),
                        width: MediaQuery.of(context).size.width,
                        height: MediaQuery.of(context).size.height,
                        child: new RTCVideoView(_remoteRenderer),
                        decoration: new BoxDecoration(color: Colors.black54),
                      )),])

it work fail. it also show _localRenderer full screen.
but when I change code like this:

new Stack(children: <Widget>[
          new Positioned(
                      left: 0.0,
                      right: 0.0,
                      top: 0.0,
                      bottom: 0.0,
                      child: new Container(
                        margin: new EdgeInsets.fromLTRB(0.0, 0.0, 0.0, 0.0),
                        width: MediaQuery.of(context).size.width,
                        height: MediaQuery.of(context).size.height,
                        child: new RTCVideoView(_remoteRenderer),
                        decoration: new BoxDecoration(color: Colors.black54),
                      )),
                  new Positioned(
                      left: 0.0,
                      right: 0.0,
                      top: 0.0,
                      bottom: 0.0,
                      child: new Container(
                        margin: new EdgeInsets.fromLTRB(0.0, 0.0, 0.0, 0.0),
                        width: MediaQuery.of(context).size.width,
                        height: MediaQuery.of(context).size.height,
                        child: new RTCVideoView(_remoteRenderer),
                        decoration: new BoxDecoration(color: Colors.black54),
                      )),])

just add Positioned Widget again.it work well,show _remoteRenderer now.

Omitting the "video" attribute does not help.

Voice chat

Hi, Thanks for developing this library
I want to implement an audio chat with this library
is this possible?
tried to

1. remove video tracks after stream creation but no success.
   E/flutter ( 3259): MissingPluginException(No implementation found for method mediaStreamRemoveTrack on channel cloudwebrtc.com/WebRTC.Method)
2. removing video from constraints map
   null exception error

Support volume control for recorded audio

Since webrtc encapsulates audio capture, it's desirable to control the volume (or gain) of the recorded audio track. I propose to add method MediaStreamTrack.setVolume(double volume), which would apply a gain multiplier to an audio track. The underlying WebRTC API has the corresponding volume control methods, which are platform-specific and exist for both iOS and Android.

How to choose an audio / video codec?

Need help, please tell me:

1. Logs say that the default codec is H264. How to specify VP9 video codec and OPUS audio codec in configuration?
2. And another question: how can you quickly switch the established connection to the "audio only" mode, when we do not send and do not receive the video track?
   And then re-enable video conferencing?

Rendering fails when video width < 720

Hi dear.
I wonder why this has changed.
If it changes like this, no video will be output.
After that, however, the video is output again.
Please answer me. ;(

No Audio while Video streaming

Hi, I want to thanks for this plugin! It's cool man!
I've able to streaming a video now.
Why there's no audio?
Edit : Ok, it is a audio codex then! Thank you!

Getting access to raw audio data

Just wondering if there is anyway to intercept the audio data as a raw data stream of sorts. Need raw audio data so that some signal processing (silence removal) can be done. Thanks!

Documentation

without documentation It makes it difficult to work with it

At least one of the methods is a documentary, such as the sound of the camera switch between two cameras and set the default camera setting or send a message

compileOptions breaks the apk.

I added these compileOptions as suggested in the app level build.gradle file to make it build in my Android Studio.
But the .apk I build will crash on my android test phone.
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
Any solution?

webrtc history is to be made

very impressive and become the leading flutter master ,even beyond google itself

Enable/disable torch

I'm currently implementing torch feature for my needs
Should I provide PR for that?
If yes, how this API should look like?
Method on mediastream or general static method?

One-to-many example with pions/webrtc

https://github.com/pions/webrtc

Pion WebRTC aims to solve all that! Built in native Go you should be able to send and receive media and text from anywhere with minimal headache. These are the design principals that drive Pion WebRTC and hopefully convince you it is worth a try.

proper idea to use webrtc

I'm having a p2p chat app in flutter using firebase firestore. I want to have p2p video call in that app when user user clicks video call button they both should able to make video call. but I'm unable to get started, as I can't understand signalling server, ice, turn and other things.🤯🤯 can you please elaborate the things that how can I start using firestore to make video call feature possible in app. just using the plugin will make it possible or what I have to do!

great job.

since Flutter is new to us but popular in the near future what you did is actually great job. 很厉害

Cant get MediaStream twice

Getting the MediaStream for the first time is no problem at all and adding it to a PeerConnection. The second time I add the same stream to another PeerConnection it says the Camera is already in Usage. Is there an Method to disable the camera? To dispose the Stream doesn't work out for me.
