PODetect TCP connection close when playing Flash video
text
Body
copied!<p>On the Flash client side, how do I detect when the server purposely closes the TCP connection to its video stream? I'll need to take action when this occurs - maybe attempt to restart the video or display an error message. Currently, the connection closing and the connection being slow look the same to me. The <code>NetStream</code> object ushers a <code>NetStream.Play.Stop</code> event in both cases. When the connection is slow, it usually recovers by itself within seconds. I wish to only take action when the connection is closed, not when it is slow. </p> <p>Here's how my general setup looks like. It's the basic <code>NetConnection</code>-><code>NetStream</code>-><code>Video</code> setup.</p> <pre><code>this.vidConnection = new NetConnection(); this.vidConnection.addEventListener(AsyncErrorEvent.ASYNC_ERROR, this.connectionAsyncError); this.vidConnection.addEventListener(IOErrorEvent.IO_ERROR, this.connectionIoError); this.vidConnection.addEventListener(NetStatusEvent.NET_STATUS, this.connectionNetStatus); this.vidConnection.connect(null); this.vidStream = new NetStream(this.vidConnection); this.vidStream.addEventListener(AsyncErrorEvent.ASYNC_ERROR, this.streamAsyncError); this.vidStream.addEventListener(IOErrorEvent.IO_ERROR, this.streamIoError); this.vidStream.addEventListener(NetStatusEvent.NET_STATUS, this.streamNetStatus); this.vid.attachNetStream(this.vidStream); </code></pre> <p>None of the error events fire when the server closes the TCP or when the connection freezes up. Only the <code>NetStream.Play.Stop</code> event fires. Here's a trace of what happens from initially playing the video to the TCP connection closing.</p> <pre><code>connection net status = NetConnection.Connect.Success playStream(http://192.168.0.44/flv/4d29104a9aefa) NetStream.Play.Start NetStream.Buffer.Flush NetStream.Buffer.Full NetStream.Buffer.Empty checkDimensions 0 0 onMetaData NetStream.Buffer.Full NetStream.Buffer.Flush checkDimensions 960 544 NetStream.Buffer.Empty NetStream.Buffer.Flush NetStream.Play.Stop </code></pre> <p>When I do a dump on various properties during the connection closing and connection being slow, I see no distinctive values that could help me differentiate closing and slowness.</p> <pre><code>NetConnection->connected = true NetConnection->connectedProxyType = none NetConnection->proxyType = none NetConnection->uri = null NetConnection->usingTLS = false VidStream->bufferLength = 0 VidStream->bufferTime = 0.1 VidStream->bytesLoaded = 3204116 VidStream->bytesTotal = 3204116 VidStream->currentFPS = 0 VidStream->time = 63.797 </code></pre>
