aardio调用NetSDK.dll实现网络摄像头IP Camera的打开和预览

By admin at 2023-03-01 • 0人收藏 • 831人看过

前面说到用ocx实现了这款网络摄像头的打开和操作, 那是因为官方杭州熊迈不提供32位库了, 只有64位的库, 然后我安装官方的摄像头软件VSM lite发现它自己用的倒是32位的.....

于是, 我花了点时间将这个32位的dll研究了下, 网上找了不少之前32位的库的文档,

然后在aar中调用这个netsdk.dll,我用c#简单粗暴的封装了个NetSDKEx.dll类库, 里面只有简单的init和open函数, 可以更简单的使用了.( ̄▽ ̄)"


这种方式与前面ocx方式的优缺点比较:

优点: 不用申请管理员模式去regsvr32 注册ocx

缺点: 这个编译的是dotnet框架4.7.2, 需要你电脑里安装过.net框架

附上NetSDKEx的c#类库代码工程:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using WinNetSDK.Class;
using WinNetSDK.Struct;
using static WinNetSDK.Class.CppLibWrapper;
using SDK_HANDLE = System.Int32;

namespace NetSDKEx
{
    public class VideoCard
    {
        public bool Init()
        {
            SDK_HANDLE ret =  H264_DVR_Init(null, IntPtr.Zero);
            if (ret<=0)
            {
                return false;
            }
            return true;
        }

        public bool Open(string ip , ushort dk , string user , string mima ,IntPtr handle)
        {
            int data = 0;
            H264_DVR_DEVICEINFO info = new H264_DVR_DEVICEINFO();
            SDK_HANDLE lgid = H264_DVR_Login(ip, dk, user, mima, ref info, out data, 0);
            if (lgid>0)
            {
                H264_DVR_CLIENTINFO cliinfro = new H264_DVR_CLIENTINFO();
                cliinfro.hWnd = handle;
                SDK_HANDLE playID = H264_DVR_RealPlay(lgid, ref cliinfro);
                return true;
            }
            return false;
        }
    }
}

如果是c#直接调用NetSDK.dll库的话 , c#代码如下:

private void Form1_Load(object sender, EventArgs e)
{
            
    CppLibWrapper.H264_DVR_Init(null, IntPtr.Zero);
    H264_DVR_DEVICEINFO info = new H264_DVR_DEVICEINFO();

    int data = 0;
    var lgid =  H264_DVR_Login("192.168.1.165", 34567, "admin", "",ref info,out data,0);
    H264_DVR_CLIENTINFO cliinfro= new H264_DVR_CLIENTINFO();
    cliinfro.hWnd = this.pictureBox1.Handle;
    SDK_HANDLE playID = H264_DVR_RealPlay(lgid, ref cliinfro);
            
}

用c#将64位的这个netsdk给重新封装了下, 只保留一个函数

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Configuration;
using System.Text;
using System.Threading.Tasks;
using User.XNetSDK;
using XSDK_HANDLE = System.Int32;
namespace NetSDKEx
{
    public class Video
    {
        public bool Open( string iPaddrss , IntPtr PicHandle)
        {
            SXSDKInitParam InitParam = new SXSDKInitParam();
            XNetSDK.XSDK_Init(ref InitParam);

            SXSDKLoginParam LoginInfo = new SXSDKLoginParam();
            LoginInfo.sDevId = iPaddrss;    //IP addrss
            LoginInfo.sUserName = "admin";  //User name
            LoginInfo.sPassword = "";  //Password
            LoginInfo.nDevPort = 34567;  //Port
            LoginInfo.nCnnType = EDEV_CNN_TYPE.EDEV_CNN_TYPE_AUTO;
            XSDK_HANDLE hLoginID = XNetSDK.XSDK_DevLoginSyn(ref LoginInfo, 500);
            if (hLoginID > 0)
            {
                SXMediaRealPlayReq param = new SXMediaRealPlayReq();
                param.nChannel = 0;              // Channel (required)
                param.nStreamType = 0;                  // Stream type (required)
                param.nRequestType = (int)EXSDK_DATA_FORMATE.EXSDK_DATA_FORMATE_FRAME;  // Data type
                param.hShowWindows = PicHandle;       // Window handle
                param.nDecodeType = (int)EXNetSDK_EDECODE_RESULT.DECODE_RESULT_NULL;
                XNetSDK.XSDK_MediaRealPlay(hLoginID, ref param, 0, 0);
                return true;
            }
            else
            {
                return false;
            }
        }
    }
}

用的时候, 直接open

var video1 =  new NetSDKEx.Video();
var ret = video1.Open(端口1, pictureBox1.Handle);
if (!ret){
   MessageBox.Show("摄像头1打开失败!", "错误", MessageBoxButtons.OK, MessageBoxIcon.Error);
}

抽空研究了下官方提供的64位XNetSDK.dll库 , 比较坑的是官方没提供参数配置的示例, 而参数配置需要用 json 字符串上传和下载的方式 , c#我不是很熟, 有些奇怪的json格式不知道怎么去转换到c#对象, 所以我就用最原始的方式直接修改json字符串的方式来修改默认参数.

比如: 我需要摄像头 Flip 和Mirror 上下镜像和左右镜像 ,

bool flip = false;
        bool mirror = false;


        private void testtttToolStripMenuItem_Click(object sender, EventArgs e)
        {
            if (!flip)
            {
               
                IntPtr szOutBuffer = Marshal.AllocHGlobal(40960);
                int nInOutSize = 40960;
                XNetSDK.XSDK_DevGetChnConfigSyn(_hLoginID, 0, "Camera.Param", szOutBuffer, ref nInOutSize, 4000, 1042);
                Console.WriteLine(nInOutSize);
                string result = Marshal.PtrToStringAnsi(szOutBuffer);
                Console.WriteLine(result);

                result = result.Replace(" \"PictureMirror\" : \"0x00000000\",", " \"PictureMirror\" : \"0x00000001\",");
                Console.WriteLine(result);

                XNetSDK.XSDK_DevSetChnConfigSyn(_hLoginID, 0, "Camera.Param", Encoding.Default.GetBytes(result), nInOutSize, szOutBuffer, ref nInOutSize, 4000, 1040);


            }
            else
            {
                IntPtr szOutBuffer = Marshal.AllocHGlobal(40960);
                int nInOutSize = 40960;
                XNetSDK.XSDK_DevGetChnConfigSyn(_hLoginID, 0, "Camera.Param", szOutBuffer, ref nInOutSize, 4000, 1042);
                Console.WriteLine(nInOutSize);
                string result = Marshal.PtrToStringAnsi(szOutBuffer);
                Console.WriteLine(result);

                result = result.Replace(" \"PictureMirror\" : \"0x00000001\",", " \"PictureMirror\" : \"0x00000000\",");
                Console.WriteLine(result);

                XNetSDK.XSDK_DevSetChnConfigSyn(_hLoginID, 0, "Camera.Param", Encoding.Default.GetBytes(result), nInOutSize, szOutBuffer, ref nInOutSize, 4000, 1040);

            }

            flip = !flip;

        }

        
        private void flipToolStripMenuItem_Click(object sender, EventArgs e)
        {
            if (!mirror)
            {

                IntPtr szOutBuffer = Marshal.AllocHGlobal(40960);
                int nInOutSize = 40960;
                XNetSDK.XSDK_DevGetChnConfigSyn(_hLoginID, 0, "Camera.Param", szOutBuffer, ref nInOutSize, 4000, 1042);
                Console.WriteLine(nInOutSize);
                string result = Marshal.PtrToStringAnsi(szOutBuffer);
                Console.WriteLine(result);

                result = result.Replace(" \"PictureFlip\" : \"0x00000000\",", " \"PictureFlip\" : \"0x00000001\",");
                Console.WriteLine(result);

                XNetSDK.XSDK_DevSetChnConfigSyn(_hLoginID, 0, "Camera.Param", Encoding.Default.GetBytes(result), nInOutSize, szOutBuffer, ref nInOutSize, 4000, 1040);


            }
            else
            {
                IntPtr szOutBuffer = Marshal.AllocHGlobal(40960);
                int nInOutSize = 40960;
                XNetSDK.XSDK_DevGetChnConfigSyn(_hLoginID, 0, "Camera.Param", szOutBuffer, ref nInOutSize, 4000, 1042);
                Console.WriteLine(nInOutSize);
                string result = Marshal.PtrToStringAnsi(szOutBuffer);
                Console.WriteLine(result);

                result = result.Replace(" \"PictureFlip\" : \"0x00000001\",", " \"PictureFlip\" : \"0x00000000\",");
                Console.WriteLine(result);

                XNetSDK.XSDK_DevSetChnConfigSyn(_hLoginID, 0, "Camera.Param", Encoding.Default.GetBytes(result), nInOutSize, szOutBuffer, ref nInOutSize, 4000, 1040);

            }

            mirror = !mirror;

        }

上面就是简单的把1变0 , 0变1 .....

先暂时这样用吧
