直接上代碼，unity幫我們內(nèi)置了功能。

using System.Collections; using UnityEngine; using UnityEngine.UI;public class Test : MonoBehaviour {// 圖片組件public RawImage rawImage;//圖形組件父實(shí)體public RectTransform imageParent;//當(dāng)前相機(jī)索引private int index = 0;//當(dāng)前運(yùn)行的相機(jī)private WebCamTexture currentWebCam;void Start(){StartCoroutine(Call());}public IEnumerator Call(){// 請求權(quán)限yield return Application.RequestUserAuthorization(UserAuthorization.WebCam);if (Application.HasUserAuthorization(UserAuthorization.WebCam) && WebCamTexture.devices.Length > 0){// 創(chuàng)建相機(jī)貼圖currentWebCam = new WebCamTexture(WebCamTexture.devices[index].name, Screen.width, Screen.height, 60);rawImage.texture = currentWebCam;currentWebCam.Play();//前置后置攝像頭需要旋轉(zhuǎn)一定角度,否則畫面是不正確的,必須置于Play()函數(shù)后rawImage.rectTransform.localEulerAngles = new Vector3(0, 0, -currentWebCam.videoRotationAngle);}}//切換前后攝像頭public void SwitchCamera(){if (WebCamTexture.devices.Length < 1)return;if (currentWebCam != null)currentWebCam.Stop();index++;index = index % WebCamTexture.devices.Length;// 創(chuàng)建相機(jī)貼圖currentWebCam = new WebCamTexture(WebCamTexture.devices[index].name, Screen.width, Screen.height, 60);rawImage.texture = currentWebCam;currentWebCam.Play();//前置后置攝像頭需要旋轉(zhuǎn)一定角度，否則畫面是不正確的,必須置于Play()函數(shù)后rawImage.rectTransform.localEulerAngles = new Vector3(0, 0, -currentWebCam.videoRotationAngle);}}
