Hi!
I think this is just a beginner question...i´ve searched the message archive for a few pages, but didn´t get a hint on my problem.
I installed JMF and Fobs4JMF on my Windows XP. I did the installation instructions for Fobs4JMF:
* Installed JMF
* Installed Fobs4JMF with the installer
* adapted the classpath (.;.;C:\PROGRA~1\JMF21~1.1E\lib\sound.jar;C:\PROGRA~1\JMF21~1.1E\lib\jmf.jar;C:\PROGRA~1\JMF21~1.1E\lib;C:\Programme\Fobs4JMF\fobs4jmf.jar;C:\Programme\Fobs4JMFjmf.jar)
* copied the fobs4jmf.dll into win/sys32 and java/lib/i386 folder
* copied the *.properties from fobs folder into the jmf folder
Now i´m able to play for example avi files with the JMF JMStudio. So i think all is fine now. If i try to play the same avi file out of a small java application i get a exception like the above.
I think this is not a big problem...just a small thing. i forgot to tell, that i even added fobs4jmf.jar in my build path of my application.
this is the exception:

ok, i just did some further debuging. The Application runs, when i am not using my own video effects. In this video effect i only analyse the frames which the input buffer brings me...
...how can i now make use of this effect?
