copied!<p>Use the NetConnection statuses rather: NetConnection.Connect.Closed</p> <p>I ran into a similar issue & noticed that the NetStream.bytesTotal value is truncated when a video connection fails. Thus, capture the video length in bytes according to the NetStream to begin with & use it to detect a failure when NetConnection.Connect.Closed is called.</p> <p>Because video code is so impossible to explain out of context I put this together, building on Flash's example @ <a href="http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/NetConnection.html#includeExamplesSummary" rel="nofollow">Flash NetConnection Example</a></p> <p>Here's the code, comments inline:</p> <pre><code>public class NonTruncatedNetConnectionExample extends Sprite { private var videoURL:String = "http://www.helpexamples.com/flash/video/cuepoints.flv"; private var connection:NetConnection; private var stream:NetStream; private var video:Video = new Video(); // ADDITION: special length variable to check for truncation private var videoBytes:uint; public function NonTruncatedNetConnectionExample() { connection = new NetConnection(); connection.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler); connection.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler); connection.connect(null); } private function netStatusHandler(event:NetStatusEvent):void { switch (event.info.code) { case "NetConnection.Connect.Success" : connectStream(); break; case "NetStream.Play.StreamNotFound" : trace("Stream not found: " + videoURL); break; // ADDITION: this will be triggered when the connection is closed // on completion, or on failure case "NetConnection.Connect.Closed" : if (this.videoBytes != this.stream.bytesTotal) { // failure // you can throw the error here // or in the loadingProgress function below } else { // success // the video loaded completely } break; } } private function securityErrorHandler(event:SecurityErrorEvent):void { trace("securityErrorHandler: " + event); } private function connectStream():void { var stream:NetStream = new NetStream(connection); stream.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler); stream.client = new CustomClient(); video.attachNetStream(stream); stream.play(videoURL); addChild(video); // ADDITION: the loadingProgress function this.addEventListener(Event.ENTER_FRAME, loadingProgress); } /*** ** ADDITION : loadingProgress captures the length of the video in bytes for use in comparison when ** NetConnection.Connect.Closed is called ** It also tracks current loading progress so you can use it as a buffer indicator */ private function loadingProgress(E:Event):void { // check that this.stream.client has initialised & you have correct access to this.stream variables // bytesTotal is also a divisor so must be greater than 0 before continuing, or it will hard-fail if (this.stream.client && this.stream.bytesTotal > 0) { // sanity checker ;) trace("bytesLoaded = " + this.stream.bytesLoaded + " :: bytesTotal = " + this.stream.bytesTotal); // capture the video's total bytes only if the variable does not yet exist // before this point this.stream.bytesTotal returns a bogus (really big) number // watch out for capturing this.stream.totalBytes before this point, or you create a double negative, // because it won't match the actual bytesTotal & will therefore error [ it got me :( ; but then I got it ;) ] if (!this.videoBytes) this.videoBytes = this.stream.bytesTotal; // compare this to stream.totalBytes to detect truncation if (this.videoBytes != this.stream.bytesTotal) { // error // you can throw the error here if you want, or wait for the NetConnection.Connect.Closed switch above } else { // or you can detach this event listener here while just holding on to the videoBytes variable // & wait for the NetConnection.Connect.Closed switch above // e.g. this.removeEventListener(Event.ENTER_FRAME, loadingProgress); } // use this to drive a buffer bar if you want var radian:Number = (this.stream.bytesLoaded / this.totalBytes); var percent:Number = radian * 100; } } } </code></pre> <p>And also:</p> <pre><code>class CustomClient { public function onMetaData(info:Object):void { trace("metadata: duration=" + info.duration + " width=" + info.width + " height=" + info.height + " framerate=" + info.framerate); } public function onCuePoint(info:Object):void { trace("cuepoint: time=" + info.time + " name=" + info.name + " type=" + info.type); } } </code></pre>
