Tried to add a camera video track to existing audio only localstream and published it with sfu.publish(). Camera stream is visible on local device.

ion.LocalStream _stream = await ion.LocalStream.getUserMedia(
            constraints: ion.Constraints.defaults);
await localStream.stream.addTrack(_stream.stream.getVideoTracks()[0]);
await sfu.publish(localStream);

What did you expect?

sfu.ontrack to trigger for all users

      };

      var pc = transports[RolePub]!.pc;
      if (pc != null) {
        var offer = await pc.createOffer({});
        await pc.setLocalDescription(offer);
        print('Step 1');
        var answer = await signal.join(sid, uid, offer);
        print('Step 2');                                         <-------- This line is never called

Your environment.

• Flutter: 2.8.1
• SDK Release: v1.0.0
• Device: iOS and Android

What did you do?

Tested the ion-app-flutter with our own server. No modifications made to backend code. Audio and video work fine.

What did you expect?

Expected onPeerEvent to trigger for all users (those already in the room AND those who just joined) to retrieve Peer object for displaying user information.

What happened?

onPeerEvent is only triggered for users who are already in the room, not for the user joining. Once this user is in the room, onPeerEvent is triggered for every new user thereafter. This was not the behavior in previous releases (i.e. v0.5.4 and below)

If this is how it should behave, what method/listener should I rely on to get Peer information of existing users upon joining?

Side question - How can users update their Peer information (name, extrainfo, role, etc) and send the update to every user in the room?

on track event is triggered when joined back . but peer event is not triggered. thus no way to recognise who is in the room

Flutter 2.0 is out with support for null safety in the stable branch. It would be really nice if ion-sdk-flutter supported sound null safety

When I switched to the back camera using:
_localVideo.stream.getVideoTracks()[0].switchCamera();
the back camera display is inverse. Any solution to avoid this ?

nginx 配置websocket，room, rtc连接被closed,可能是因为room连接没有数据交互，被nginx closed，是否可以在websocket连接后，加入心跳消息, ping,pong message.

About the native client of Android/iOS/macOS/Web,
We can use Google Flutter to build a native client outside the browser, which will allow the mobile/desktop to perfectly connect to the ion.

• In the early stage, we can pre-compile APK or IPA using CodeMagic?
• When we have the official ion service, we can upload the app to App Store and GooglePlay,

(Linux, Windows, Fuchsia will be supported in the future)

What did you do?

I am running sfu-ion (./cmd/signal/json-rpc/main.go) on a ec2 instance and am able to connect fine using my own domain with caddy reverse proxy and websockets.

What did you expect?

When another peer joins the same session, I would expect ontrack to be called so I can get the remote stream

What happened?

When another peer joins the same session id, ontrack never gets called so I don't have the remote stream. This could be something very small I am overlooking, but can't seem to figure out what I am missing.

但是用release方式打包apk运行，会停滞在
await _rtc.join(_room, _uid, JoinConfig());
这句一直等待，最后一条收到的状态是：

一直都没有COMPLETE消息，但是如果取消await关键字来调用
_rtc.join(_room, _uid, JoinConfig());
不等待的话，就可以正常通讯，也可以收到COMPLETE消息
我还试着clone了[ion-app-flutter]项目来以release方式打包，出现了一样的问题，也是在rtc.join时候卡住，但是debug模式却正常

Summary

I want to init a client and set its role on the session (Publisher or Subscriber or both).
A publisher will only send data.
A subscriber will only receive data.

Motivation

I want to create an app where theres 1 subscriber and multiple publishers but I want them all on the same session.
There are N publishers and 1 subscriber.
I want the server to only route the video of the publishers to the subscriber, and not to the other publishers since they are not going to consume any video, only send.

Describe alternatives you've considered

client.create({
 sid: sid,
 uid: uid,
 signal: signal,
 role: role // Maybe this can be an array of roles
});

What did you do?

Due to our project requirements, we need to have an ability for a user to take a photo during video calls and send that image to the other participants. In order to do something like that we explored multiple approaches and the only viable approach would be to use captureFrame(path) method that Flutter WebRTC provides on local video MediaStreamTrack. The main reason for such a decision is that Ion SDK "locks" the camera even when you disabled it, and you can't open a second session for that camera until local video stream is connected. It would be very bad UX that user just disappears when he wants to take the photo and that is why we chose to utilize captureFrame(path) method since it exists.

In order to do something like this we simply changed in your example project in pubspec.yaml we added a dependency:

path_provider:

and in the meeting_page.dart:

//Switch local camera
  _switchCamera() async {
    if (_localVideo != null && _localVideo.stream.getVideoTracks().length > 0) {
      //_localVideo.stream.getVideoTracks()[0].switchCamera();
      final storagePath = await getTemporaryDirectory();
      final filePath = storagePath.path + '/test.jpg';
      _localVideo.stream.getVideoTracks()[0].captureFrame(filePath);
    } else {
      _showSnackBar(":::Unable to switch the camera:::");
    }
  }

In ios/Runner/Info.plist we added:

<key>NSPhotoLibraryAddUsageDescription</key>
<string>write</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>write</string>

What did you expect?

Application should capture a frame and save it in the JPG file.

What happened?

The application crashed without any stacktrace when run on iOS 13.2.

We also tested the official Web RTC sample which supports captureFrame and it worked as expected without any crash.

Hello,

Can I develop an app which connects to other WebRTC WEB apps with this SDK?

Thank you,

Summary

One paragraph explanation of the feature.

Motivation

Why are we doing this? What use cases does it support? What is the expected outcome? Is this available in other implementations? Can this not be implemented using primitives?

Describe alternatives you've considered

A clear and concise description of the alternative solutions you've considered.

Additional context

Add any other context or screenshots about the feature request here.

When connecting and on subsequent client connections, the web app throws an uncaught type error. Chrome points to zone.dart line 1175, firefox does the same but points to client.dart line 487.

Reopened in sdk as this issue is caused by the event emitter library, events2. I was able to fix by changing the dependency and converting the library to use https://pub.dev/packages/eventify. This workaround is not viable for most users, but does resolve the problem.

Client joins but hangs at waiting for others to join. You can see your own camera and hear your own audio, but you cannot hear any other participants as they never show joined to the room. The SFU logs indicate multiple peers are connected, and publishing.

What did you do?

// Setup handlers
client.on('peer-join', (rid, id, info) async {});

client.on('peer-leave', (rid, id) async {});

client.on('transport-open', () {}));

client.on('transport-closed', () {});

client.on('stream-add', (rid, mid, info, tracks) async {
// handle stream-add
});

client.on('stream-remove', (rid, mid) async {
// handle stream-remove
});

client.on('broadcast', (rid, uid, info) async {
// handle broadcast
});

What did you expect?

I need to know how to handle these request in Current version. In current version there is only ontrack?

Android 11

• Need flutter-webrtc/flutter-webrtc#99 to land first
• Dependent on signaling #22

Hi author, I notice in flutter-webrtc's example they have a method onRemoveRemoteStream to know remote stream has been removed. But I try found the same method in your lib, it doesn't exist. Please help me if I miss something.

to replicate

dont code anything just add it in dependency

flutter_ion: ^0.1.2

terminal

flutter pub get
flutter build apk --release

run the apk.
the app wont run at all.
is there additional configuration for released apps?
