I am doing research in reconstructing dynamic physical models based
on image analysis.  Java has produced a marvelous, yet marvelously
complex, API for working with current realtime media standards.  I do
not have the time to learn the complexities of the new API, but I do
want to learn to add in my own image manipulation effects and analysis
to a realtime stream.

An answer to this question must contain working example code that
takes a video stream from a local web-cam, inverts the colors, and
displays the result as real-time video to the screen.  I will give
bonus karma points to the researcher who does the processing in a
method with the following signature:

byte[][][] processFrame(byte[][][] inputFrame);

So far I have found the following resources:
JMStudio: Source code for all basic JMF operations:

It is ok if there is a minimal delay and missing frames in order to
accomidate processing time.  Useing a Frame Grabber thread is fine. 
Also if the solution is a just a modification of the JMStudio example
code, that is fine too.

I know that there are multiple places to put image processors:
preprocessors, postprocessors, and renders.  Any of these solutions
are fine, so long as the video on the screen is processed and is as
near realtime as possible.

I just want an exmaple of one way to do it, and any way is fine with
me.

Thank you for your interest in my question studboy-ga.  I'm just gonna
figure this out my self this weekend, so I'm closing the question.

I don't think you can invert a real time stream on the fly--
you can invert one frame at a time and concatenate them together,
but it won't be real time as the inversion will take time.
If you need to do this you will need to write your own processor/player,


See:

and:

Let me know whether this is what you want to do.

It is ok if there are a few seconds of delay and missing frames.  I
will add this as a clarification.
