I've been asked to write an app were the user can slow down or speed up video and even reverse it. Only video is required, no audio.
I've done a test with a Quicktime movie and using setRate(). It didn't work, though, as the rate always stays at 1.0 no matter what I set.
Do I need to use a specific codec for it to work? It there something about setRate() that I overlooked?
I'm starting to fear that I need to create a Controller myself. Unfortunately the reference implementation on the Sun site (http://java.sun.com/products/java-media/jmf/2.1.1/guide/JMFApp-Controller.html) is missing 2 important classes: EventPoster & BasicClock.
Anyone have an implementation of those? Or have an idea how to do one?

No exception is thrown when I use it so that isn't the problem.

My Quicktime clip uses the CVID codec so maybe that's the problem. I'll try it with an MPEG next.
