InputDeviceInfo

InputDeviceInfo.getCapabilities()

Returns a MediaTrackCapabilities object describing the primary audio or video track of a device's MediaStream.

The following example gets all media devices with MediaDevices.enumerateDevices(). If any of the devices are input devices then console.log(device) will print an InputDeviceInfo object to the console.

navigator.mediaDevices.enumerateDevices().then((devices) => {
  devices.forEach((device) => {
    console.log(device); // an InputDeviceInfo object if the device is an input device, otherwise a MediaDeviceInfo object.
  });
});
