[karansingla007]

@LichKing-2234
yes, i did that

same configuration and same APP_ID is working on android native

here is my code:-

 Future<void> setTranscoding(int uid) async {
    try {
      List<AgoraLiveTranscodingUser> agoraLiveUserList =
          cdnLayout(uid, _users, 360, 640);
      await AgoraRtcEngine.setLiveTranscoding(AgoraLiveTranscoding.fromJson({
        'width': 480,
        'height': 640,
        'videoBitrate': 1800,
        'videoFramerate': 15,
        'transcodingUsers': agoraLiveUserList,
        'watermark': AgoraImage('https://imgur.com/zt3pL7e', 0, 0, 100, 100),
        'backgroundImage':
            AgoraImage('https://imgur.com/zt3pL7e', 0, 0, 100, 100),
        'audioSampleRate': AgoraAudioSampleRateType.MidRateType,
        'audioChannels': 2,
        'audioBitrate': 48,
        'videoCodecProfile': AgoraVideoCodecProfileType.High
      }));
      await AgoraRtcEngine.addPublishStreamUrl(
          'rtmp://a.rtmp.youtube.com/live2/deqj-h312-m17h-bbkf', true);
    } catch (error, stackTrace) {
      print(error);
      print(stackTrace);
    }
  }

here, i set my layout.

List<AgoraLiveTranscodingUser> cdnLayout(
      int bigUserId, List<int> publishers, int canvasWidth, int canvasHeight) {
    List<AgoraLiveTranscodingUser> users = [];
    int index = 0;
    double xIndex, yIndex;
    int viewWidth;
    int viewHEdge;
    if (publishers.length <= 1) {
      viewWidth = canvasWidth;
    } else {
      viewWidth = canvasWidth ~/ 2;
    }
    if (publishers.length <= 2) {
      viewHEdge = canvasHeight;
    } else {
      viewHEdge = canvasHeight ~/ ((publishers.length - 1) / 2 + 1);
    }
    users.add(AgoraLiveTranscodingUser.fromJson({
      'uid': bigUserId,
      'width': viewWidth,
      'height': viewHEdge,
      'x': 0,
      'y': 0,
      'zOrder': 0,
      'alpha': 1,
      'audioChannel': 0
    }));
    index++;
    for (int entry in publishers) {
      if (entry == bigUserId) continue;
      xIndex = index % 2.0;
      yIndex = index / 2;
      users.add(AgoraLiveTranscodingUser.fromJson({
        'uid': entry,
        'width': viewWidth,
        'height': viewHEdge,
        'x': ((xIndex) * viewWidth).toInt(),
        'y': (viewHEdge * (yIndex)).toInt(),
        'zOrder': index + 1,
        'alpha': 1,
        'audioChannel': 0
      }));
      index++;
    }
    return users;
  }

it seems like a bug of native code, could you help me to confirm it?

[LichKing-2234]

dart invoke method with enum value, but native wants the index value.

[karansingla007]

@LichKing-2234
i hardcode the values but still not working. my stream is not redirecting to youtube.

[plutoless]

@singlakaran i think there's a callback named rtmpStreamingStateChanged, could you pls listen to that event to see what state value you get?

[jajuat]

@LichKing-2234 Who can help up with this issue? Is there something we are missing in implementation or its an SDK bug?

[LichKing-2234]

@jajuat @singlakaran the SDK has some bug, you can try this.

And refer to this doc

await AgoraRtcEngine.setChannelProfile(ChannelProfile.LiveBroadcasting);
await AgoraRtcEngine.setClientRole(ClientRole.Broadcaster);

[karansingla007]

@LichKing-2234
i hardcode the values but still not working. my stream is not redirecting to youtube.

@LichKing-2234 i already tried this
that was not working for me.

[LichKing-2234]

@singlakaran have you setChannelProfile to ChannelProfile.LiveBroadcasting?

[karansingla007]

yes, @LichKing-2234
i already set

await AgoraRtcEngine.setChannelProfile(ChannelProfile.LiveBroadcasting);

[plutoless]

@singlakaran could you pls double check that you have enabled RTMP converter as following

if not please help provide your project, we may help take a look.

[karansingla007]

@plutoless i already enabled

[jajuat]

The published stream you see if when @singlakaran published via Android SDK. The Android SDK works for us, we are successfully able to stream to You Tube, the same settings in Flutter SDK doesn't work.

[LichKing-2234]

@singlakaran @jajuat pls provide your complete dart code about init and join, I will help to check it.

[karansingla007]

@LichKing-2234
i used agora_rtc_engine 1.0.11

but i got error
java.lang.Integer cannot be cast to java.lang.Double
when i call setLiveTranscoding method.

you can see my sample project
https://github.com/singlakaran/agoarCdn

i set parameters according to:-
https://docs.agora.io/en/Audio%20Broadcast/cdn_streaming_android?platform=Android

[LichKing-2234]

try this, I will update later

[karansingla007]

@LichKing-2234 i tried this, but no luch
this time it did not give me any error, but its not redirecting my stream to youtube.

[LichKing-2234]

@singlakaran i think there's a callback named rtmpStreamingStateChanged, could you pls listen to that event to see what state value you get?

pls provide the params of this callback

[karansingla007]

@LichKing-2234
i used these params

  Future<void> setTranscoding(int uid) async {
    try {
      List<AgoraLiveTranscodingUser> agoraLiveUserList =
          cdnLayout(uid, _users, 360, 640);

      await AgoraRtcEngine.setLiveTranscoding(AgoraLiveTranscoding.fromJson({
        'width': 480,
        'height': 640,
        'videoBitrate': 1800,
        'videoFramerate': 15,
        'transcodingUsers': agoraLiveUserList,
        'watermark': AgoraImage('https://imgur.com/zt3pL7e', 0, 0, 100, 100),
        'backgroundImage':
            AgoraImage('https://imgur.com/zt3pL7e', 0, 0, 100, 100),
        'audioSampleRate': AgoraAudioSampleRateType.MidRateType,
        'audioChannels': 2,
        'audioBitrate': 48,
        'videoCodecProfile': AgoraVideoCodecProfileType.High
      }));
      await AgoraRtcEngine.addPublishStreamUrl(
          'rtmp://a.rtmp.youtube.com/live2/deqj-h312-m17h-bbkf', true);
    } catch (error, stackTrace) {
      print(error);
      print(stackTrace);
    }
  }

users.add(AgoraLiveTranscodingUser.fromJson({
        'uid': entry,
        'width': viewWidth,
        'height': viewHEdge,
        'x': ((xIndex) * viewWidth).toInt(),
        'y': (viewHEdge * (yIndex)).toInt(),
        'zOrder': index + 1,
        'alpha': 1,
        'audioChannel': 0
      }));

[LichKing-2234]

I think you misunderstood me,I want to see the return value of the callback rtmpStreamingStateChanged

[LichKing-2234]

you can reopen this issue if the problem still exists.
