Troubleshooting

Camera not detected: "Not able to access selected media device"

Why the live room can't open your camera or microphone, and how to get into the green room.

Symptom

When you click Enter Room from a webinar's Overview tab, the device check asks you to choose your camera, microphone and speakers, then shows:

Not able to access selected media device

and Continue to Green Room stays greyed out.

Why it happens

The live room needs a working camera and microphone before it lets you into the green room. The button stays greyed out until the room can see both. You can turn them off once you are in, but you can't enter without them.

The message appears when the room can't open the camera or microphone you selected.

Fix it

Work through these in order and check the device preview after each one.

  1. Allow camera and microphone access for EasyWebinar when your browser asks. If you blocked it earlier, change the site's camera and microphone permission in your browser settings, then reload the page.
  2. Close other apps that are using the camera, such as another video-call tool, then reload.
  3. Pick the right device in the device check if you have more than one camera or microphone.

Verify the fix

The device check shows your camera preview and microphone, and Continue to Green Room becomes clickable. Nothing in the green room is broadcast; the header reads Not Live until you click Go Live.

"You can only have one event live at a time."

This appears on Enter Room when another of your webinars is already live, because only one webinar can be live at a time. Join that one from its Overview tab, or go live with the new one.

Prevent it next time

Enter the room well before your start time. The green room broadcasts nothing, so you can pass the device check, finish your checks and test Share before anyone is watching. Close other video-call tools before you click Enter Room, so nothing else is holding the camera. For the kit itself, see the webinar equipment guide and this host preparation guide.

Common questions

Can I enter the room with my camera off?

Not at first. A camera and microphone are required to enter, even if you turn them off afterwards with the Camera and Mic controls in the green room.

Will attendees see me while I fix my camera?

No. Nothing in the green room is broadcast, and the header reads Not Live until you click Go Live.

Can I switch camera or microphone once I'm in?

Yes. Click Settings in the room's top bar; Device settings covers camera, audio and recording.

My co-host has the same message. What do they do?

The same fixes apply on their computer. Co-hosts and moderators who get in land backstage, not on stage, so your audience doesn't see or hear them until you bring them on. A guest co-host or moderator joins with the Co-presenter Join Link or the Moderator Join Link from the Share dialog.

Still stuck?
