Yup this isn't working for me either.

You are facing this issue because tracking js is not able to find the video stream. for your video html element use an id or query selector like: In html

var videoElement = document.getElementById("video") videoElement.srcObject= stream; //stream is a var in which we have our video streaming

let me know if it's still not resolved. There might be some other issues with way you are streaming your video.

//stream is a var in which we have our video streaming

@GautamUpreti123 and where is this coming from?

GautamUpreti123 commented 5 years ago

you can use: MediaDevice api Use following link to get video stream ( https://developer.mozilla.org/enUS/docs/Web/API/MediaDevices/getUserMedia )

var contraints = { audio: true, video: { facingMode: "user" } } Navigator.mediaDevices.getUserMedia(contraints).then((stream)=>{ var videoStream = stream;
})

Please do let me know if your issue gets resolved or not.
