Nope, currently you have to create a player. Once a player is created it kicks off a parser to grab metadata or waits for the underlying native player to parse.

There were plans, there were also issues as we don't have a Java based mp4 parser so we're relying on the underlying platforms (e.g. QTKit, AVFoundation, etc..) to provide that data, which basically means we're creating a player at the native level anyways. If you're using the horribly outdated FXM format you get the benefit of a Java based parser, but honestly, who's using that these days?
