          I created an app in JMF that accesses the webcam, the deployment was via java webstart.
          It is very important that you sign ALL jars that are required by the app; however I chose not to use an applet for the app as a thick client was far better and java web start can update your app whenever a new version is available.

            Hi ,

            I have to inform you , I could made the JApplet which work fine to access local webcam , You are right I need to sing the jar file , but there is some other issue which you need to add one more line into your code before you call frame grab method .
              System.setProperty("java.class.path", "C:\\Program Files (x86)\\JMF2.1.1e\\lib\\jmf.jar");
            There is other problem I am facing now .Which could not find the answer for it . I want to access two webcam at same time with my application , But some how I get error and would not let me to connect to both camera in same time .

            Any idea ?

              Unfortunately I only have one webcam so I cant test this myself, but I assume you can change the int value in the mediaLocator; in the below code its 0 maybe try add another mediaLocator with the value of 1?

              String strDevice = "vfw:Microsoft WDM Image Capture (Win32):0";
              mediaLocator = new MediaLocator("vfw://0");

              you will probably need multiple instances of player too (for each mediaLocator)
              player = Manager.createRealizedPlayer(mediaLocator);

              //Something like this....
              String strDevice0 = "vfw:Microsoft WDM Image Capture (Win32):0";
              mediaLocator0 = new MediaLocator("vfw://0");
              player0 = Manager.createRealizedPlayer(mediaLocator0);

              String strDevice1 = "vfw:Microsoft WDM Image Capture (Win32):1";
              mediaLocator1 = new MediaLocator("vfw://1");
              player1 = Manager.createRealizedPlayer(mediaLocator1);

              If I can get my hands on another webcam I will try it myself; I hope you get it to work.

                It did work on that way , I know I am doing something silly . that's why it create problem .

                Other thing I am trying but nowhere could find anything about it . Is I have 2 IP Camera and I would like to capture stream from it . Then display it . But no hope . Did you try before ?

                I have both camera public and accessible from internet . I can capture MotionJPG by using normal 2D java but because it is loading image by image and draw it in the screen . roughly display 4 frame per second which not acceptable for my project .

                Any body can help to sort it out with JMF ?
