Как отобразить видеопоток Janus?

Добрый день. Я не могу разобраться как вставить MediaStreamTrack в элемент video в Janus. Когда я добавляю MediaStreamTrack в MediaStream и через него пытаюсь вставить видеопоток, он не отображается в элементе video.

Janus.init({
  debug: true,
  dependencies: Janus.useDefaultDependencies(), // or: Janus.useOldDependencies() to get the behaviour of previous Janus versions
  callback: function() {

  }
})

let janus = new Janus(
    {
      server: 'http://147.45.158.188:8088/janus',
      success: function() {
// Done! attach to plugin XYZ
        let echotest=null;

// Attach to echo test plugin

        janus.attach(

            {

              plugin: "janus.plugin.echotest",
              success: function(pluginHandle) {
                // Negotiate WebRTC
                console.log("FFF")
                echotest = pluginHandle;

                echotest.createOffer(
                    {
                      // We wantbidirectional audio and video, plus data channels
                      tracks: [
                        { type: 'video', capture: true, recv: true },
                        { type: 'audio', capture: true, recv: true },

                      ],
                      success: function(jsep) {
                        // Got our SDP! Send our OFFER to the plugin
                        var body = {request:'start'}
                        echotest.send({ message: body, jsep: jsep });
                      },
                      error: function(error) {
                        // An error occurred...
                        console.error(error);
                      },
                      customizeSdp: function(jsep) {
                        // if you want to modify the original sdp, do as the following
                        // oldSdp = jsep.sdp;
                        // jsep.sdp = yourNewSdp;
                      }
                    });
              },

              onmessage: function(msg, jsep) {

// Handle msg, if needed, and check jsep
                if(jsep) {

// We have the ANSWER from the plugin
                  echotest.handleRemoteJsep({jsep: jsep});

                }

              },


              onlocaltrack: function(track, added) {

// Invoked after createOffer

// This is info on a local track: when added, we can choose to render
                if (added) {
                  var video = document.getElementById("#local")


                  const stream = new MediaStream([track]);
                  

                  video.srcObject = stream;

                  
                }

              },})
              },
              onremotetrack: function(track, mid, added, metadata) {

// Invoked after handleRemoteJsep has got us a PeerConnection

// This is info on a remote track: when added, we can choose to render

// You can query metadata to get some more information on why track was added or removed

// metadata fields:
                if (added) {
                  var video = document.getElementById("#local")


                  var stream = new MediaStream()
                  stream.addTrack(track);
                  video.srcObject = stream;
                  
                }


      },

      error: function(cause) {
// Error, can't go on...
        console.error(cause);
      },

      destroyed: function() {
// I should get rid of this
      }
    });
