A DESCRIPTION OF THE PROBLEM :
Using MediaPlayer to play an AAC Audio Stream over HTTP fails with following Exception:

MediaException: MEDIA_UNSUPPORTED : Unrecognized file signature!
at javafx.scene.media.Media._setError(Media.java:513)
at javafx.scene.media.Media$InitLocator.run(Media.java:566)
at java.base/java.lang.Thread.run(Thread.java:833)

Here two URLs which don't work:
<link1>
<link2>

The error occurs in com.sun.media.jfxmediaimpl.MediaUtils, mehod: fileSignatureToContentType.

I noticed the bytes which are used to identify the stream type are always different, so I assume the content available at the URL does not start with a header which allows the client to identify the stream type. I think the content starts with the audio data directly.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a MediaPlayer, with a Media instance set to a HTTP Url like this:

Media media = new Media("<Link>")

And then call .play() on the media player.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The audio content is played.
ACTUAL -
An Exception:

MediaException: MEDIA_UNSUPPORTED : Unrecognized file signature!
at javafx.scene.media.Media._setError(Media.java:513)
at javafx.scene.media.Media$InitLocator.run(Media.java:566)
