Did the video buffer update this frame?
Use this to check if the video buffer has changed since the last frame. When setting a low frame rate, it is likely that the video updates slower then the game, so it does not make sense to do expensive video processing in each Update call, so check this value before doing any processing.
var webcamTexture : WebCamTexture;
var data : Color32[];
function Start () {
// Start web cam feed
webcamTexture = WebCamTexture();
webcamTexture.Play();
data = new Color32[webcamTexture.width * webcamTexture.height];
}
function Update () {
if (webcamTexture.didUpdateThisFrame)
{
webcamTexture.GetPixels32 (data);
// Do processing of data here.
}
}
