For those trying to get the camera to render live feed, here's how I managed to pull it off. First, I edited Bart's answer so the texture would be assigned on Update rather than just on Start:

void Start()
{
    webCamTexture = new WebCamTexture();
    webCamTexture.Play();
}

void Update()
{
    GetComponent().texture = webCamTexture;
}

Then I attached the script to a GameObject with a RawImage component. You can easily create one by Right Click -> UI -> RawImage in the Hierarchy in the Unity Editor (this requires Unity 4.6 and above). Running it should show a live feed of the camera in your view. As of this writing, Unity 5 supports the use of webcams in the free personal edition of Unity 5.

I hope this helps anyone looking for a good way to capture live camera feed in Unity.
