Although this is an off-topic I'll answer to your question.

Security and testing are the reasons.
It's virtually impossible to test every possible codec on every possible 
platform. Many of them are proprietary so we don't control their 
code/can't fix their bugs. And all blame that JavaFX can't play 
this/can't play that will fall on our heads.
And it can open many potential security vulnerabilities.
