Java 实现海康摄像头抓拍图片

 

本人遇到的问题描述：我的电脑是64位系统，32位jdk，刚开始下载了64位的SDK，一直报 ：Unable to load library 'HCNetSDK': ÕҲ»µ½ָ¶¨ 这种错，后来更换了32位的 SDK，成功，所以应该和 jdk 版本有关系和电脑系统没关系。

 

引入：log4j-1.2.16.jar，quartz-2.2.1.jar，slf4j-api-1.6.6.jar，slf4j-log4j12-1.6.6.jar

将 SDK 中的库文件全部放到 src 文件夹下，引入 SDK 中的两个 jar：examples.jar，jna.jar

 

import java.io.File;
import java.io.UnsupportedEncodingException;
 
public class HCNetSDKPath {
 
    
    public static String DLL_PATH;
    static{
        String path=(HCNetSDKPath.class.getResource("/").getPath()).replaceAll("%20", " ").substring(1).replace("/", "\\");
        try {
            DLL_PATH= java.net.URLDecoder.decode(path,"utf-8");
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }

    }
}

更改 HCNetSDK.java：

将：HCNetSDK INSTANCE = (HCNetSDK) Native.loadLibrary("../lib/HCNetSDK", HCNetSDK.class);
改为：HCNetSDK INSTANCE = (HCNetSDK) Native.loadLibrary(HCNetSDKPath.DLL_PATH+"HCNetSDK.dll", HCNetSDK.class);

将：boolean  NET_DVR_CaptureJPEGPicture_NEW(NativeLong lUserID, NativeLong lChannel, NET_DVR_JPEGPARA lpJpegPara, String sJpegPicBuffer, int dwPicSize,  IntByReference lpSizeReturned);
改为：boolean  NET_DVR_CaptureJPEGPicture_NEW(NativeLong lUserID, NativeLong lChannel, NET_DVR_JPEGPARA lpJpegPara, ByteBuffer sJpegPicBuffer, int dwPicSize,  IntByReference lpSizeReturned);
