Depth/rgb direct pass to nuitrack sdk

is there possible to pass our generated(from file for example) depth/rgb/pointcloud to nuitrack with help of sdk instead of getting frames from sensors? With the reason for direct use of skeleton tracking and gesture recognition features in nuitrack.?

No this is not possible currently for a number of technical reasons.

Nuitrack licencing works by creating an association between the runtime and a specific device - and hard wires the communication between this device and the SDK as part if the Licence Activation process.

Each time Nuitrack starts - it tests that the valid licenced device is being communicated with - and will only return results from this device.
