Yes.

Hmm, looks like a poor choice from Oracle there, but maybe 0.10.x was 
the current stable release when they decided on the Java 8 ABI.

Thanks for the info. I personally can live without the JavaFX (in fact I 
don't use it so it would be hard for me to test) so I'll pass on making 
another ffmpeg-compat package. Perhaps someone else will come forward 
if/when they need it.

Cheers, Paul.
