Java games rock!


« Posted 2013-02-18 23:22:02 »

Hey guys,

after trying godzillions of video-playback approaches, I returned to give JavaFX a try. There have been a few recent updates on tutorials and indeed, there is one working (still have to prove it for Mac and Linux through). My problem is that I want to display the video on a custom component. In my case that component is the UI of Slick2D. Can anyone hint me if there is a simple way to either paint the video on any graphics context or just create a frame and then grab it?
The code I made run from the turorial is like that:
