JMF JMStudio - video capture software - empty vector of devices

[jx2]

Hi guys im having a big problem with JMF and i would appreciate your help...

i saw a lot of source codes with these two lines
unfortunatly this doesnt work for me:

Vector deviceList = CaptureDeviceManager.getDeviceList(new VideoFormat(VideoFormat.YUV));
        di = (CaptureDeviceInfo)deviceList.firstElement();
 
 

(Vecor is empty)
[PHP]Exception in thread "main" java.util.NoSuchElementException
at java.util.Vector.firstElement(Vector.java:442)
at Main.main(Main.java:58)[/PHP]

JMStudio works properely with no problems
any idea how can i repair it?
(im using windows Vista , HP laptop, built in webcam)

thank you

Do you have RGB or MPEG VideoFormat devices?

Itried allof them
incuding

Vector deviceList = CaptureDeviceManager.getDeviceList(null);
 

however YUVFormat.YUV_YUYV is the one which works in JMStudio

i downloaded JMStudio source code and its working
( ive got others problems with it)
i'm confused ! and i cant find the problem , all example source code loook like mine(but only JMStudio works) so where is the problem?

Thank You

Maybe JMStudio adds devices to that CaptureDeviceManager before your code
starts; can you manually add devices as well? See the API docs for that manager.

JMStudio is trying to load device from registers(which is confusing cos there is no registers) after it fail its serching for devices and add them to the list and then iam able to start capturing :( its very confuzsing and i need the simpliest posible way of doing it...

manually

its seems its one of those problems which can make someone mad :)

When in Rome, do as the Romans (JMStudio) do. If you have its sources, rip
out the relevant code and add it to your own code. That should work.
