Manage Webcam & Screen Sharing

In this post, we will cover everything about the streams management in the webinar room. If you feel lost in the webinar room, this is a good place to start. Once your webinar is published, you can go to the webinar room. Just click on " Access webinar room" at the top of your webinar dashboard.


States of your webinar room

First, let's look at the top of your webinar room. As explained in this post, contributors can join the webinar room before it starts. Attendees won't be able to enter the room until you click on the green "Start webinar" button. If they try to enter the room before, they'll be redirected to a waiting page waiting for the webinar to start. 

Your top bar should look like this:

Note the label "Not started yet". This label indicates the current state of the webinar room. When you have the "Not started yet" label you are in what we call a green room. A preparation room if you prefer.

This is what you have when you start the webinar:

The "Live" label indicates that you are streaming live and your webinar is getting recorded. If you're on stage, everybody in the webinar room can see you or hear you.

How to activate your webcam and microphone

When you join in the webinar room for the very first time, you will have to allow your browser to access to your webcam and microphone.

Click on "Allow" to allow access:

This is very important: you must allow permissions, otherwise you won't be able to go on stage to share your audio / video with your attendees. You'll get this error message instead:

If you blocked permissions by error, don't worry! You can always allow permissions again by on the lock icon to the left of your address bar:

How to go on stage

In order to go on stage, you need to be on Chrome, Firefox, Opera or Safari (v.12.1 and up)  and connect from a computer.

Every time you enter the webinar room, you will be prompted with a popup like this one:

You can configure your settings before going on stage. You can share your webcam (or disable it) and your microphone. If you'd like to use an external device (for example an external USB microphone or webcam), this is also where you'd choose it. Watch the green bar on the side to see if there's any sound captured.

Next time you enter the room we will keep the same settings. If you want to change those settings just click on the gear icon (in the middle of the Dock).

If you close this window by mistake, don't worry. You can always go back on stage by clicking the green " Go on stage" button.

Once you've configured your audio / video click "Apply and go on stage". Once you're on stage, you'll be seen and heard by everyone. Your audio, video and screen sharing will also be recorded once you start your webinar.

At the bottom of the screen, there are 5 buttons, this is what we call the "Dock". It enables you to control your streams. Click on each icon to manage your video, audio or screen sharing:

Push to Talk

If you're on stage and have your microphone muted, you can press the M key in your keyboard to unmute your microphone. You'll be unmuted as long as you keep pressing the M key. Push to talk won't be enabled if you're not on another browser tab/application, or if you're writing in the Chat tab of the webinar room.

How to use an external webcam or microphone

If you'd like to use an external device (for example an external USB microphone or webcam), you can select it when you first enter the webinar room ( explained above) or you can change your audio/video settings by clicking on the little gear icon in the middle of the Dock:

A popup will open, you will be able to switch between devices:

If the external device does not appear in the select menu, refresh the page first and open the device settings again. Your device should appear in the dropdown menu afterwards.

How to use the screen sharing

Screen sharing is great for presenting a Powerpoint or a software and have it recorded in the replay. In a few clicks, you can share everything happening on any app or on your entire screen. Click on the screen icon (second one from the right) on your Dock:

Bear in mind that you need to be on Chrome, Firefox, Opera or Safari (v.12.1 and up) and connect from a computer to share your screen. 

On Safari, screen sharing is only supported on versions 13 and up ⚠️

πŸ’‘Pro tip πŸ‘‰You can share your screen without going on stage as well! All you have to do in this case, is to click on "Actions" and choose "Enable screensharing".


To use the screen sharing you have to use our Chrome extension. If the extension is not installed, we will display a notification pop up asking to download the extension. Once you have installed it, you don't need to reload the page, just click on the screen icon again (picture above).

This will trigger a popup. You can share your entire screen (if you have an extra monitor) or just share a window or an application:

Starting from Chrome version 72, you don't need to download our extension. In addition, you can also share a single Chrome tab instead of an application window or your entire screen. 


For Firefox, you don't have to download an extension. You'll be able to share an application window our your entire screen natively. Just select whether you'd like to share an entire screen or an application window from that menu:

Once you make a selection, Firefox will then ask you to give permission to Livestorm to allow screen sharing. You'll be able to select which application / screen you'd like to share from the popup:

You have to give Livestorm browser permissions to share your screen. If you don't, you'll get this warning:

In this case, click on the screen sharing icon to the left of your address bar to manage your screen sharing permissions:

You can then clear the blocked permission. Once removed, click on the screen share icon in your Dock again. This way, Firefox will ask you to give permission one more time. Click "Allow" and you'll be able to start your screen sharing afterwards. 


If you'd like to use Opera to screen share, it will be a two-step process. As we don't have a native Opera extension for now, you'd have to use our Chrome extension instead:

First you'll have to install Chrome Extensions for Opera. You can install the extension here.

Once that's added to your browser, you can download our Chrome extension. If the extension is not installed, we will display a notification pop up asking to download the extension. Once you have installed it, you don't need to reload the page, just click on the screen share icon again in your Dock to start your screen sharing:

That's it, you're good to go!

How to share the screen of your mobile or tablet?

You can share the screen of your mobile or tablet in the webinar room. But first you'd need to mirror your device's screen to your computer. Once mirrored, you can use screen sharing to project your device's screen in the webinar room.

Apple Devices

If you're using an iPhone or an iPad, you can use QuickTime Player to share the screen of your device. Here are the steps:

  1. Connect your device to your computer
  2. Open up Quicktime on your computer. Select File > New Movie Recording
  3. Access your webinar room and start a screen share

Going from here, you have two options: 

- You can share your entire screen including the device:

- Or share just the screen of your device under  Application window. It will be listed as a movie recording:

Android Devices
