WebCamTexture.didUpdateThisFrame

説明

最後のフレームから更新されているかどうか

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 will update slower than the game. Since it would not make sense to do expensive video processing in each Update call, check this value before doing any processing.

using UnityEngine;

public class ExampleScript : MonoBehaviour
{
    WebCamTexture webcamTexture;
    Color32[] data;

    void Start()
    {
        // Start web cam feed
        webcamTexture =  new WebCamTexture();
        webcamTexture.Play();
        data = new Color32[webcamTexture.width * webcamTexture.height];
    }

    void Update()
    {
        if (webcamTexture.didUpdateThisFrame)
        {
            webcamTexture.GetPixels32(data);
            // Do processing of data here.
        }
    }
}
