High Performance, Cross-Platform Media Device Streaming for Unity Engine

Media Devices Made Easy

NatDevice is a cross-platform media device API. NatDevice simplifies your camera and microphone workflows. First, discover a media device:
Camera
Microphone
// Create a device query for a camera device
var filter = MediaDeviceCriteria.CameraDevice;
var query = new MediaDeviceQuery(filter);
// Get the camera device
var device = query.current as CameraDevice;
// Create a device query for a microphone device
var filter = MediaDeviceCriteria.AudioDevice;
var query = new MediaDeviceQuery(filter);
// Get the microphone device
var device = query.current as AudioDevice;
Then start streaming media data from the device:
Camera
Microphone
// Start streaming camera images
device.StartRunning(OnCameraImage);
void OnCameraImage (CameraImage cameraImage) {
// Do stuff
...
}
// Start streaming audio sample buffers
device.StartRunning(OnAudioBuffer);
void OnAudioBuffer (AudioBuffer audioBuffer) {
// Do stuff
...
}
From here, you can utilize tons of functionality provided by media devices to build your interactive applications.
