I have written a code in java using JMF api for audio-video capturing. I am using Windows Vista operating System.
When I am running the program from console it can detect all devices well and record video and audio both.
Now I am try to deploy it using Java Web Start. Then it can not detect any of the devices. First I think it is security problem.
Then I off User Access Control. But still it return same result.
I have repeat the same steps in windows-xp where it is running successfully. Java and JMF are properly installed class paths are properly set in environment variables.
I think it is a vista restriction problem.

Please help me......
Thanks in advance....

i am Working on JMF but it is in linux..CentOS
i used to run jmfinit inorder to register the capture device..
otherwise it show an error no capture device connected..

one more thing if the capture device for example Web cam is having its own application to capture...sometimes it will lock the device to prevent other programs from using the device.

check that too..


Have you come across any exception..if so please post it

Are you sure its not showing any exception..

i think you can track out the problem if you use some dialog box instead of System.out.println() to print the Exceptions..

did you try in that way..

If you think there is a Vista restriction problem, then the test for that theory would be to try it on a machine which isn't running Vista.
 
It is sorta covered in the JavaRanch Style Guide.
