Java application to play a video with transparent background

Hello, I need to play a .mov video with transparency over a .jpg picture. I am using JMF in a Java application for that purpose. I could probably use a better media library, but this is the one that I know well, so I would only change it for another if absolutely necessary. Recently I found out that JMF only supports the h.263 codec, while transparency requires the h.264 codec. It seems like some tricks exist to natively play the video, as explained on the following links: [login to view URL] [login to view URL] [login to view URL] I would be deeply grateful if someone with experience in this subject could provide a short sample piece of code which can be executed in order to ensure a proper working application on both Windows and Linux (Ubuntu) systems.
