NatDevice is a high performance, cross-platform camera and microphone API for Unity Engine. To start, discover available media devices:
// Create a media device query for a camera device
var filter = MediaDeviceCriteria.CameraDevice;
var query = new MediaDeviceQuery(filter);
// Get the first camera device
var device = query.current as CameraDevice;

Then stream camera images or audio buffers from the device:
// Start streaming camera images

void OnCameraImage (CameraImage image) {
    // Do stuff

From here, you can utilize extensive functionality provided by the API to build your interactive applications. Features include:
  • Ultra-low Latency. Stream the camera preview and microphone audio into Unity with extremely small overhead.

  • Ultra-high Resolution. NatDevice supports high resolution camera previews, at full HD and higher on devices that support it.

  • Extensive Camera Control. Set the camera exposure mode, exposure point, exposure duration, focus mode, focus point, flash mode, white balance mode, torch mode, zoom, and more.

  • Granular Microphone Control. Configure the microphone sample rate, channel count, and echo cancellation mode on devices that support it.

  • Machine Learning Integration. NatDevice tightly integrates with NatML for building machine learning and computer vision apps.

  • Video Recording Integration. NatDevice tightly integrates with NatCorder for enabling user-generated content.
