getFrameRate() returns 0

[flanagaj]

I don't get what is going on here.  The avi file loads fine and starts playing.  It even prints out the println in the console and shows the correct frame rate of the avi file

Fobs4JMF - Native shared library found
8298.08First Position: 0, 0 Duration: 8298083
Frame Rate: 24

If I however call getFrameRate on the FrameRateControl as shown below.  It returns 0.

fpc = (FramePositioningControl)mediaPlayer.getControl("javax.media.control.FramePositioningControl");
frc = (FrameRateControl)mediaPlayer.getControl("javax.media.control.FrameRateControl");

Time duration = mediaPlayer.getDuration();
float frameRate = frc.getFrameRate();

If you can help it would be most welcome as seeking to a particular frame is the most important function that I need for my application and without a way of getting the frame rate I cannot deduce the frame to move to given the time.

Thanks

my code playing an m4v file gives this output:

my code:

fpc = (FramePositioningControl)p.getControl("javax.media.control.FramePositioningControl");

if (fpc == null) {
System.err.println("The player does not support FramePositioningControl.");
return false;
}

returns a non-null fpc.

I am lost.  You get the frame rate from a FrameRateControl not a FramePositioningControl ?

Is this forum dead.  eg are any Devs from the Fobs4jmf actually posting on here ?
