Network.bufferingProgress

The bufferingProgress property retrieves the percentage of buffering completed.

Syntax

player.network.bufferingProgress

Possible Values

This property is a read-only Number (long).

Remarks

Each time playback is stopped and restarted, this property is set to zero. It is not reset if playback is paused.

Buffering only applies to streaming content. This property returns valid information only during run time, when the Player.URL property is set.

Use the Player.Buffering event to determine when buffering starts or stops.

Examples

The following JScript example uses Network.bufferingProgress to display the percentage of buffering completed. The information is displayed in an HTML DIV created with ID = "BP". The example uses a timer with a 1-second interval to update the display. The Player object was created with ID = "Player".



<!-- Create an event handler for buffering. -->
<SCRIPT FOR = Player EVENT = buffering(Start)>
   var idI; // Variable for the interval id.

   // Test whether buffering has started or stopped.
   if (true == Start){ 
      // Start the timer. Call the function to update the display every second.
      idI = window.setInterval("UpdateBP()", 1000);
   }

   else{
      // Buffering is complete. Stop the timer.
      window.clearInterval(idI);
   }
</SCRIPT>

<!-- Put the function to update the display in a separate code block. -->
<SCRIPT>
function UpdateBP(){
   BP.innerHTML = "";
   BP.innerHTML = "Buffering progress: " + Player.network.bufferingProgress;
   BP.innerHTML += " percent complete";
}
</SCRIPT>
