Get the (sometimes estimated) average frame rate of this container.<br>
For variable frame-rate containers (they do exist) this is just<br>
an approximation.  Better to use getTimeBase().<br>
<br>
For contant frame-rate containers, this will be 1 / ( getTimeBase() )<br>
<br>
@return The frame-rate of this container.
