Hello sarxos.. I have problem while connecting USB webcam on Raspbian

OS : 2018-11-13-raspbian-stretch JRE on Raspbian : OpenJDK Runtime Environment (build 1.8.0_181-8u181-b13-2~deb9u1-b13) Hardware : Raspberry Pi 3B + USB Logitech C170 for testing

Coding using JDK 7 update 80 with netbeans 8.1 on windows 10

Library :

• bridj-0.7.0.jar
• slf4j-api-1.7.2.jar
• slf4j-simple-1.7.25.jar
• v4l4j-0.9.1-r507.jar
• webcam-capture-0.3.12.jar
• webcam-capture-driver-v4l4j-0.3.12.jar (i add them all because i don't know where library that work with raspbian (arm device))

Error: sudo java -jar /home/pi/SvrFiles/RaspberryCamera.jar Exception in thread "main" java.lang.UnsatisfiedLinkError: /tmp/libs6762512599666073353/libvideo.so: libjpeg.so.8: cannot open shared object file: No such file or directory at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1941) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1857) at java.lang.Runtime.loadLibrary0(Runtime.java:870) at java.lang.System.loadLibrary(System.java:1122) at com.github.sarxos.v4l4j.NativeUtils.loadLibraryFromJar(NativeUtils.java:98) at com.github.sarxos.v4l4j.V4L4J.init(V4L4J.java:50) at com.github.sarxos.webcam.ds.v4l4j.V4l4jDriver.(V4l4jDriver.java:33) at raspberrycamera.WebcamAccess.(WebcamAccess.java:11) at raspberrycamera.t.(t.java:23) at raspberrycamera.RaspberryCamera.main(RaspberryCamera.java:18)

My Code : package raspberrycamera;

import com.github.sarxos.webcam.Webcam; import com.github.sarxos.webcam.ds.v4l4j.V4l4jDriver; import java.awt.Dimension; import java.awt.image.BufferedImage;

public class WebcamAccess { public WebcamAccess() { Webcam.setDriver(new V4l4jDriver()); }
private boolean opened=false; private Webcam wc=null; public boolean open(){ try{ wc=Webcam.getDefault(); wc.setViewSize(new Dimension(640,480)); opened=wc.open(); }catch(Exception e){} return opened; } public BufferedImage getImage(){ if(opened)return wc.getImage(); else return open()?wc.getImage():null; } public void close(){ wc.close(); wc=null; opened=false; } } Note : This code work fine on windows without set driver "Webcam.setDriver(new V4l4jDriver());"

Any suggestion? Thank you...
