Issue with auido/video (media devices) in Microsoft Teams App

Copper Contributor

I am trying to build a Microsoft Teams app, that will be either used inside the call or as a "Tab". In my application I am using user's audio/video and screen sharing. I have created an app as a Tab, but the permission are not there for the media devices. So those features are not working. Is there a way or a different integration type so I can have media devices available in my app. Here (link attached below) you can see that class has an integration within the call with audio/video. So I guess it should be possible.

In my application I put an iframe in the html, which opens my app. I have used Micrososft Teams Tabs. Maybe the issue comes from an iframe.

Hello @ChetanSharma-msft. Thanks for the reply.


I've tried this but can't get it working:


media.requestPermission().then(permissions => { console.log("permissions", permissions); }).catch(e => { console.log("permissions error", e); });

const mediaObj = new media.Media();
const log = (err, blob) => {
    if (err) {
        console.log("err", err);
    if (blob) {
        console.log("blob", blob);

I checked my manifest. If I get it right I have the needed permission. This is my manifest.json:

@ArmenKakosyan Sorry, I would try to help, I know some code but not this complex like you do! Good job, keep it up! :hearteyes:

Thank you :D Is there a place or a contact where I can reach out to get more information or maybe a walkthrough on how can I get this done?
