Detecting the end of a video stream

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.
