Question

我目前正在一个项目中，我必须从Jetson TX1向PC发送和接收帧。目前，我有一个在github上找到的客户，但问题出在接待部分。框架必须统一存放，因为它们必须显示在VR头盔中。目前，这是我用于接收和显示框架的代码：

using System.Net;
using System.Net.Sockets;
using UnityEngine;
using System;

public class Test : MonoBehaviour
{
    Socket socket;
    int port = 5356;

    private bool stopping = false;
    byte[] buffer;
    int recvMasgSize;
    Texture2D texture;
    Renderer renderer;
    private object e;

    void Start()
    {
        renderer = new Renderer();
        renderer = GetComponent<Renderer>();`enter code here`
        texture = new Texture2D(2, 2);
        IPEndPoint endpointReceive = new IPEndPoint(IPAddress.Any, port);
        socket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
        socket.Bind(endpointReceive);
        socket.Blocking = false;
        buffer = new byte[65540];
        Debug.Log("start");
    }

    void Update()
    {
        do
        {
            Debug.Log("waiting");
            recvMasgSize = socket.Receive(buffer);
        } while (recvMasgSize > sizeof(int)); //wait for the first information containing image size
        Debug.Log("received");
        int total_pack = (int) buffer[0];
        Debug.Log(total_pack);
        byte[] longbuf = new byte[4096 * total_pack];
        for (int i = 0; i< total_pack; i++)
        {
            recvMasgSize = socket.Receive(buffer);
            if(recvMasgSize != 4096)
            {
                Debug.Log("received unexpected packet size");
                continue;
            }
            Buffer.BlockCopy(longbuf, i * 4096, buffer, 0, 4096);
        }
        texture.LoadImage(longbuf);
        renderer.material.mainTexture = texture;
    }

}

将套接字设置为blocking = true只会导致统一崩溃，将其设置为false会生成错误（SocketException，无法完成非阻塞套接字操作。我听说了使用异步方法的可能性，但是由于所有这些都是对我来说真的很新，我真的不知道如何使用它们。希望有人能提供帮助，以便我继续进行该项目。

谢谢大家。
