Remote video not display in iOS

[ayechan-maung]

Remote video is not display in iOS device, but the video from iOS is display in Android and Browser. After I debug, the values I can get in logging from created peer connection, onAddStream, even getStats() method can get value. But I don't get the captureFrame value from onTrack function. That capture frame value can get in Android device.

        for (final streams in track.streams) {
          log(streams.getVideoTracks().toString(), name: "Get Video Tracks");
          log(streams.getVideoTracks()[0].getSettings().toString(), name: "Get Settings");
          for (final track in streams.getVideoTracks()) {
            track.captureFrame().then((frame) {
              log(frame.toString(), name: "Track Frame");
            });
          }
        }
        // List<MediaStreamTrack> videoTracks = track.streams[0].getVideoTracks();

      };

So, please guide the solution and I don't get any ideas what's going wrong.

I thought it because of video can not encode for iOS device.

This event listener is not listen in RTCVideoRenderer initialize method. In Android, it's listen and update the video value.
In iOS, it's not.

Hello @ayechan-maung, have you achieved any success in this problem?

I fixed the codec in sdp answer, to VP8. It currently work.

In my case I downgraded flutter_webrtc plugin and it worked. I think latest versions has codec problem, because I can't even show localstream in iOS.

Could you show how you fixed codec in the dart code?
Thanks!
