Java Build a JavaFX Application It's About Time Sounds About Right

MediaException: Could not create Player!

When I attempt to run the app, then play the sound just as shown in the video, I get a MediaException. However, if I convert to wav, it runs and plays the sound just fine. Any ideas?

Exception in thread "Thread-4" com.sun.media.jfxmedia.MediaException: Could not create player!

I've run into the same problem, not sure which OS you're using but I'm using Ubuntu 16.04. From my digging I think it's a compatibility issue between Java 8 and Ubuntu. Java wants to see libavcodec53 and libavformat53, 16.04 has libavcodec56 and libavformat56. I don't think you can downgrade these packages (I could be wrong) on newer ubuntu versions. I just use .wav file as you did, probably the easiest fix.

Check "JavaFX Media" at the bottom of this page.

Thanks, Ubuntu 16.10 has the same issue. A .wav file worked!

I had the same issue and I'm running Elementry OS based on ubuntu, using a wav file solves the problem

Hmm... can you make sure that you are importing the right MediaClip class. Make sure it's from JavaFX, not the Applet one.

The same problem on Ubuntu

Eric Schroeder Found a good link. I had the same problem on Ubuntu (Gnome) 17.04. However, instead of installing more packages (as the docs at that link suggest) I just converted the file to a .wav with VLC and that worked fine for me. Gotta love VLC.
