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);
