Question by Kpaper · Mar 20, 2017 at 12:11 PM · texture2dwebcamtexturewebcamgetpixels

When I run getPixel32 () in WebcamTexture, only black pixels are returned.

When you do getPixel32 () from WebcamTexture, the value of [0] must be RGBA (0,0,0,255).

Build on Windows x64. (Editor Result Same)

Below is a test source code.


Using System.Collections;

Using System.Collections.Generic;

Using UnityEngine;

Public class Sample: MonoBehaviour {

    [SerializeField]

    Private Color32 [] _color32;

    [SerializeField]

    Private WebCamTexture _webcamTexture;

    Void Start ()

    {

        WebCamDevice [] _webCamDevices = WebCamTexture.devices;

        _webcamTexture = new WebCamTexture (_webCamDevices [0] .name);

        _webcamTexture.Play ();

    }

    Void Update ()     {

        _color32 = _webcamTexture.GetPixels32 ();

        Debug.Log (_color32 [0]);

    }

}


When you run this simple code, RGBA (0, 0, 0, 255) is always output as the result. The webcam is not black because it normally takes a lot of shots.

And if _color32 is displayed on the sprite using setPixel32 (), the image on the webcam will display correctly.

How do I get the right Color32 [] value?

The reason I want to get this value is because I want to pass this Color32 [] value to my plug-in and process it.
