Unity 5.1, WebCamTexture not working with UITexture on Android

[Meltdown]

I'm using a WebCamTexture which updates the UITexture with whatever is seen by the device camera.

If I use a standard Unity plane and renderer as my texture, the texture is updated and shows what the camera is viewing, in both the editor and on my Android device.

However, if I use a UITexture, although the camera works in the editor and shows on the UITexture, it doesn't work on my Android device, there is just a black texture.

This is my script...
I am using NGUI 3.9.0

1. public class WebcamTest : MonoBehaviour {
2.         public string deviceName;
3.         WebCamTexture wct;
4.  
5.         [SerializeField] UITexture _uiTexture;
6.  
7.         // Use this for initialization
8.         void Start () {
9.                 WebCamDevice[] devices = WebCamTexture.devices;
10.                 deviceName = devices[0].name;
11.                 wct = new WebCamTexture(deviceName, 400, 300, 12);
12.                 //GetComponent<Renderer>().material.mainTexture = wct;
13.                 //_uiTexture.material.mainTexture = wct;
14.                 _uiTexture.mainTexture = wct;
15.                 wct.Play();
16.         }
17. }
18.

Black texture means the texture format / size is not supported on your device. Many mobile devices need power-of-two texture sizes while yours isn't (400x300). Not sure why the plain texture works while UITexture doesn't in your case.
