Enable Camera / Microphone permissions
Permission denied when trying to access the camera or microphone
Once camera / microphone permission have been denied, often accidentally, the browser won't let VDO.Ninja ask for it again. You'll need to manually change the permission to fix it, or use a different browser. How to change the permission depends on the browser and operation system.
I've provided links to some guides. If these guides are helpful for you, I'll offer a guide in VDO.Ninja to help future users when I detect permissions have been denied.
How to change a site's camera & microphone permissions
https://support.google.com/chrome/answer/2693767?hl=en&co=GENIE.Platform%3DAndroid&oco=0
Android - Chrome Browser
On your Android device, open the Chrome app
To the right of the address bar, tap More -> Settings
Tap Site Settings
Tap Microphone or Camera
Tap to turn the microphone or camera on or off; If you see the site you want to use under Blocked, tap the site -> Access your microphone -> Allow
If you’ve turned off microphone access on your device, you can control your app permissions on Android to use your mic.
If you're using a Chrome device at work or school, your network administrator can set camera and microphone settings for you. In that case, you can't change them here. Learn about using a managed Chrome device.
Chrome Desktop
Open Chrome
At the top right, click More -> Settings
Click Privacy and security -> Site settings -> Camera or Microphone
Select the option you want as your default setting - Review your blocked and allowed sites - To remove an existing exception or permission: To the right of the site, click Delete - To allow a site that you already blocked: Under "Not allowed," select the site's name and change the camera or microphone permission to "Allow."
If you still have issues, try a different browser; perhaps Firefox.

Firefox Mobile
In Firefox Mobile, you can try going to Settings -> Site permissions -> exceptions (at bottom) -> VDO.Ninja, and then manually set the permissions for the camera and microphone to enabled.
If Firefox Mobile still gives you issues afterwards, try in incognito mode, try a different browser, or fully restart the device.
Vivaldi / Brave / Opera
You can try following the same steps needed for Chrome above, however if that fails, ensure VDO.Ninja is not being loaded via an IFrame.
In the case of invite.cam for example, which loads VDO.Ninja via an IFrame, you may need to give microphone and camera permissions to both the invite.cam and VDO.Ninja domains.
You can visit invite.cam and vdo.ninja, and for each domain, ensure the microphone and camera permissions are set to allow.
iOS
On an iPhone, it's a bit more complicated: https://gagonfamilymedicine.com/how-to-give-an-app-permission-to-access-your-microphone-on-an-iphone-or-ipad/
If the issue persists, fully close Safari and try again. Sometimes updating your version of iOS and restarting can help solve issues with camera permissions as well.
IFrame permissions not provided
If embedding VDO.Ninja into a site as an IFrame, you'll not be allowed access to camera or microphones unless that IFRAME-element has allowed said permissions. See the documentation for more details
Try safe mode
Adding &safemode or &videodevice=0&audiodevice=0 to the https://vdo.ninja/ link can either try the camera in safe mode or disable the camera/microphone completely.
In either mode, you might be able to bypass the initial camera selection page, or start the system with the default camera settings.
If you are able to start the session in this mode, you can go to the VDO.Ninja gear icon (settings), click on User settings, and then clear the local storage. You can then retry, refreshing the page, and try to connect again.
