通过Texture2D来获取手机视频画面 我这里通过多个摄像头来生产RenderTexture
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class tex : MonoBehaviour
{
// Start is called before the first frame update
public RenderTexture rt;
void Start()
{
}
// Update is called once per frame
void Update()
{
byte[] by = getTexture2d(rt);
try
{
UdpClient.Client.SocketSend(by);
}
catch
{
}
}
public byte[] getTexture2d(RenderTexture renderT)
{
if (renderT == null)
return null;
int width = renderT.width;
int height = renderT.height;
Texture2D tex2d = new Texture2D(width, height, TextureFormat.ARGB32, false);
RenderTexture.active = renderT;
tex2d.ReadPixels(new Rect(0, 0, width, height), 0, 0);
tex2d.Apply();
byte[] b = tex2d.EncodeToPNG();
Debug.Log(b.Length);
Destroy(tex2d);
return b;
}
}
服务端读取renderTexture映射道Sprie上
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Servertex : MonoBehaviour
{
// Start is called before the first frame update
public Sprite sp;
void Start()
{
}
// Update is called once per frame
void Update()
{
try
{
sp.texture.LoadImage(UdpServer.image);
}
catch
{
}
}
}
