Working with video
Detecting the end of a video stream
Flash Player 9 and later, Adobe AIR 1.0 and later
In order to listen for the beginning and end of a video stream, you need to add an event listener to the NetStream
instance to listen for the netStatus event. The following code demonstrates how to listen for the various codes
throughout the video’s playback:
ns.addEventListener(NetStatusEvent.NET_STATUS, statusHandler);
function statusHandler(event:NetStatusEvent):void
{
trace(event.info.code)
}
The previous code generates the following output:
NetStream.Play.Start
NetStream.Buffer.Empty
NetStream.Buffer.Full
NetStream.Buffer.Empty
NetStream.Buffer.Full
NetStream.Buffer.Empty
NetStream.Buffer.Full
NetStream.Buffer.Flush
NetStream.Play.Stop
NetStream.Buffer.Empty
NetStream.Buffer.Flush
The two codes that you want to specifically listen for are “NetStream.Play.Start” and “NetStream.Play.Stop” which
signal the beginning and end of the video’s playback. The following snippet uses a switch statement to filter these two
codes and trace a message:
function statusHandler(event:NetStatusEvent):void
{
switch (event.info.code)
{
case "NetStream.Play.Start":
trace("Start [" + ns.time.toFixed(3) + " seconds]");
break;
case "NetStream.Play.Stop":
trace("Stop [" + ns.time.toFixed(3) + " seconds]");
break;
}
}
By listening for the netStatus event (NetStatusEvent.NET_STATUS), you can build a video player which loads the
next video in a playlist once the current video has finished playing.
Playing video in full-screen mode
Flash Player 9 and later, Adobe AIR 1.0 and later
Flash Player and AIR allow you to create a full-screen application for your video playback, and support scaling video
to full screen.
