FAQ
How to specify which camera to use?
- Use the
desiredCamera
prop. If one of the camera's name contains it, then it will be used. You can get the devices list in theonDeviceListLoaded
event. - Use the
facingMode
prop. Set it toenvironment
to use the back camera. Set it touser
to use the front camera. Please note that this is not supported on Desktop.
You can use the two props together. facingMode
has a higher priority.
