Flex 4.5 Video, NetStream, Start Buffering after calling ns.togglePause in NetStatus Handler to prevent autoplay

Posted on 2011-09-22
Last Modified: 2013-12-07
I'm working on a video player built on the Flex Framework. I'm using NetConnection, NetStream to stream from a wowza server.

I do not want the video to autoplay when loading. The only way I found to prevent this is by calling ns.togglePause() in the netStatusHandler. this works fine. However I would like to start the buffering right away. the only way I've found is to delay the initial pause in the netStatusHandler by 3 seconds, with a timer. This works but is a little dirty as the video sometimes plays a bit before the pause. But the video continues to buffer when paused, this is the behavior I'm looking for. I wish to accomplish this without using a delay to call ns.togglePause.

Is there a way to force buffering after calling ns.togglePause() in the netStatusHandler?

No, I have not found the exact behavior i was look for. But I have got it working a bit better. I just wish I was able to start the stream, in the pause state and start the buffering. I have to let it play a second or two or the buffer will stop. guess i would need to subclass netStream if that's possible.

basically this is what i'm doing:

any ideas, or secret documentation let me know...

private function netStatusHandler1(event:NetStatusEvent):void 
				switch( {
					case "NetConnection.Connect.Success":
						if ( == "NetConnection.Connect.Success")
							if ( != null)"secureTokenResponse", null,
									TEA.decrypt(, "****"));
						ns1 = new NetStream(nc1);
						ns1.bufferTime = bufTime;
						ns1.client = nsClient1;
						minorVideo = new Video();
						minorVideo.deblocking =1;
						minorVideo.smoothing = false;
						nc1Connected = true;
					case "NetConnection.Connect.Failed":

//timer is set as so

private var delayPauseTimer1:Timer = new Timer(1000, 1);

//then this is the timer function

	private function delayPause1(evt:TimerEvent):void {

Open in new window

You can solve your problem easily by set volume to zero and storing last play position.  So, when user clicking on play button you will seek to last position and setting volume to one. As soon as user will click on pause set volume back to zero

How would that help. maybe you don't understand. I wish to pause (prevent autoplay) when a stream is established. so on the netStatus handler event I call. ns.pause (or ns.togglePause). However the stream stops unless I let it play a bit then call ns.pause, and the buffer continues to store the stream, while it's paused, as the documentation states. I have no issues with the sound. Thanks anyways.

how would that help starting the stream into the buffer in the pause state? Yes i know about seek i using it. Are you an expert? this site is a joke... Maybe if you were to learn better English you might understand that I've found a workaround right away and would just like to find a cleaner way. They actually find ppl to pay to ask questions! maybe next you can suggest me to change the color of a button. Really! come on guy, all the things you have suggested are completely unrelated to the question. apparently there seems to be a problem in the framework itself, as im  not getting the behavior that on would expect after reading the documentation, possibly it on the server side and I should ask the question on the wowza forums, or maybe try the application with a FMS sever to prove this theory myself. please drop it dgofman. you dont get it. your no expert in my opinion. thanks.
