let fetchStreamButton = document.getElementById("fetchStream");
let removeTracksButton = document.getElementById("removeTracks");
async function fetchStreamFunction() {
initialStream = await navigator.mediaDevices.getUserMedia({
video: { width: 620, height: 310 },
audio: true,
});
if (initialStream) {
await attachToDOM(initialStream);
}
}
async function attachToDOM(stream) {
newStream = new MediaStream(stream.getTracks());
document.querySelector("video").srcObject = newStream;
}
async function removeTracksFunction() {
let videoTrack = newStream.getVideoTracks()[0];
let audioTrack = newStream.getAudioTracks()[0];
newStream.removeTrack(videoTrack);
newStream.removeTrack(audioTrack);
// Stream will be empty
console.log(newStream.getTracks());
}
fetchStreamButton.addEventListener("click", fetchStreamFunction);
removeTracksButton.addEventListener("click", removeTracksFunction);
