Hi!  
How to mute/unmute microphone or webcam using Web SDK for anonymous participant programmatically? (Get current user returns undefined for anonymous participant).

Hey @pavel.lychkousky,

What do you mean `anonymous participant`?

Thanks,  
Tommy

Hey @pavel.lychkousky,

The user will still have an ID which you can get from the [getCurrentUser](https://zoom.github.io/sample-app-web/ZoomMtg.html#getCurrentUser) function and then use to [mute](https://zoom.github.io/sample-app-web/ZoomMtg.html#mute) the user.

Thanks,  
Tommy

@tommy thank you, I was able to mute microphone by this code  
ZoomMtg.getCurrentUser({  
success (response) {  
ZoomMtg.mute({userId: response.result.currentUser.userId, mute: true});  
}  
});

But how can I mute video?

Hey @pavel.lychkousky,

Happy to hear you are successfully able to mute a participant! 🙂

Currently the Web SDK cannot turn on / off the video. A user has to do this themselves.

Thanks,  
Tommy
