* Return the duration of the video in seconds.

* First, try to use the native player API call to get the duration.
* If the value returned by the native function is not valid, resort to

*
* IMPORTANT! It has been observed that sometimes, after initial playback
* of the video, when operations "pause" and "play" are performed (in that
* sequence), the function will start returning a slightly different value.
*
* For example: While playing for the first time, the function returns 31.
* After pausing the video and then resuming once more, the function will
* start returning 31.950656.
*
* This instability is internal to the player API (or browser internals).
