How to play other video formats in JavaFX

Question

I am busy with a movie/video-clip player/library.

I want to do this in JavafX. Almost 90% of the video clips is in AVI format. I cannot for several reasons covert the movies/video-clips.

I also want the program to mark the video files that were played, from start to complete, so that I will know what have been watched. So the program needs to be able to interact with the video player to know when the video has played to the end.

JavafX doesn't allow playback for AVI files. What's the alternative to be able to use this with? And how will I know if the video has fully played from beginning to end.

I read the following Adding other video codecs / DVD support to JavaFX 2.2

Where they suggest I use portable VLC player. Is this the best way to use it in JavafX and if possible does the API have register hooks to register a method that can be triggered to know when the video has stopped?
