Incoming call crashes on Android #201

Open joaquin03 opened 3 years ago

joaquin03 commented 3 years ago

Hi, my app is working well, making outgoing videocalls, and if in a chrome app, receiving calls with no problem.

But when receiving calls on Android, as soon as I answer I get :

Level.error rtc_session.dart:637 ::: emit "peerconnection:setremotedescriptionfailed" [error:Unable to RTCPeerConnection::setRemoteDescription: peerConnectionSetRemoteDescription(): WEBRTC_SET_REMOTE_DESCRIPTION_ERROR: Failed to set remote offer sdp: Failed to set remote video description send parameters for m-section with mid='video-1'.]

This is the incoming SDP I get from print:

In my past experience, it is very likely that the H264 profile-level-id sent by the offer does not match the webrtc You can check the H264 profile-level-id on both sides, you should find the answer in it

joaquin03 commented 3 years ago

I saw that possible problem in forums, but I think it is alright:

  if (payload == DefaultPayloadTypeH264) {
        fmtp.add(<String, dynamic>{
          'payload': payload, 
          'config':
              'level-asymmetry-allowed=1;packetization-mode=1;profile-level-id=42e01f'
        });
      }

@joaquin03 Is this code fixing the issue for you? could you please share where should it be used? Thanks.
