Can not see the other side video

[hi-glenn]

When run the flutter-webrtc-server h5 demo on pc chrome browser, result is that:

1. Can see the other side video when not using relay mode.
2. Can not see the other side video when using relay mode.

When run the flutter-webrtc-server h5 demo on pc chrome browser and run the flutter-webrtc-demo on Android , result is that:

Can not see the other side video on Android whether or not using relay mode.

My Android phone is XiaoMi 5X.

Maybe you should check your network or turn server or provide a more detailed logcat log. Can be loopback tested successfully?

[hi-glenn]

My network and turn server is ok.
H5 demo address: https://app.axay.tk:8086/
turn server address: turnserver: "turn:app.axay.tk:3478", username: 'bbb', credential: 'ccc'

Android logcat:
flutter-webrtc-demo.log

turn server test:

Can the android device complete the loopback test?

[hi-glenn]

loopback test is ok

I think it is possible that the relay candidate does not work.
You get a relay address that looks like a private LAN IP (udp 172.19.0.2).

Thanks a lot on your prompt response.

I have a check. What you said about turn server is right . And then, I have replaced it by using coturn. Check result as below img .

But I still have a problem:

H5 demo on pc chrome browser can not see the other side H5 demo on pc chrome browser when using relay mode.

The following cases is ok ：

H5 demo on pc chrome browser can see the other side flutter-webrtc-demo on android platform whether or not using relay mode.

flutter-webrtc-demo on android platform can see the other side flutter-webrtc-demo on android platform whether not using relay mode.

May be you are providing credentials in wrong format
Or may be your turn server is misconfigured
Try AppRTC demo TURN servers

    Map<String, dynamic> ice = await AppRtcTurnClient.getIces();
    _peerCon = await createPeerConnection(ice, _constraints);

   // -------------

class AppRtcTurnClient {
  static List<dynamic> ices;
  static DateTime _expiration;

  static Future<Map<String, dynamic>> getIces() async {
    if (ices != null && _expiration.isAfter(DateTime.now()))
      return {'iceServers': ices};
    Map<String, dynamic> icesJson;
    final params = await http.get("https://appr.tc/params");
    final Map<String, dynamic> json = json.decode(params.body);
    final String isu = json["ice_server_url"];
    assert(isu != null);
    final resp = await http.post(
        isu, //url
        headers: {
          "referer": "https://appr.tc"
        }
    );
    icesJson = json.decode(resp.body);
    ices = icesJson["iceServers"];
    _expiration = DateTime.now().add(Duration(hours: 23));
    return {'iceServers': ices};
  }
}

Regards everyone, I have same problem that @GlennWang, I had tried to use the source code of @rostopira but for me don't work, I think that is STUN server configuration, could you help me with that?
