[Flashcoders] Netstream fails to close
I'm trying to fix a bug in a video player. Selecting a new video to play from a playlist, plays correctly but the first clip's audio doesn't die. I'm using NetStream.close(), it doesn't appear to work. It works if I wait for the first clip to download fully, just not if I select a new clip when the first is still loading. HELP! ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

sounds like a scope issue where you have multiple netstream objects On Thu, Jul 3, 2008 at 9:54 PM, Barry Hannah <[EMAIL PROTECTED]> wrote: > I'm trying to fix a bug in a video player. > > Selecting a new video to play from a playlist, plays correctly but the > first clip's audio doesn't die. > > I'm using NetStream.close(), it doesn't appear to work.

Re: [Flashcoders] Netstream fails to close
You have to pause() before you close().

RE: [Flashcoders] Netstream fails to close
Appreciate the responses. Pause doesn't work. There is only one netstream object instance so no scoping issue. It's a bona fide bug, I just want to know if anyone has a workaround/hack to beat it.

Re: [Flashcoders] Netstream fails to close
The only bug with NetStream that I know of is if you're spamming it with
new streams too quickly. The solution is to throttle the requests.
A safe time to wait between changing the streams is 250ms.
It's really simple to write a queueing system that does this. You just
overwrite the same variable and reset the timer.
var currentStream:String;
var timer:Timer = new Timer(250, 1);
timer.addEventListener(TimerEvent.TIMER, onTimerEvent);
function queueNewStream(value:String):void
{
currentStream = value;
timer.reset();
timer.start();
}
function onTimerEvent(event:Event):void
{
netStream.pause();
netStream.close();
netStream.load(currentStream);
}

none of which have answers that work.
I could cast the sound onto a separate object and mute it, so that you
don't see or hear any ill effects, but my proxy tells me the flv is
still downloading, so if one of my clients users clicks on 10 video
clips their connection will crawl to a halt.
Anyone?

Re: [Flashcoders] Netstream fails to close
you probably have tried this but what happens if you don't pause or close
but just try to play another stream?

Re: [Flashcoders] Netstream fails to close
Barry, FYI, I didn't just throw out an idea and pull some code out of my ass. I have tackled this exact issue for a client that needed to stop a stream from downloading when they closed the stream, and couldn't actually kill streams when the user interaction resulted in spamming new NetStreams. The solution is to throttle the requests, using the exact code I provided. If you're saying you call ns.pause(); ns.close(); ns = null; and the NetStream continues to download afterwards *when you do not attempt to open another NetStream*, then there's something else going on because that works. If you immediately try to play another stream, even if it's not on same NetStream instance, then the previous one will not stop downloading (that's the bug). When you throttle the requests for new streams, the problem goes away. -Steven ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] Netstream fails to close
And it's worth mentioning this works for AS3 Flash Player 9.0.47 only. It does not work for AS2. The first link you provided was from 2004 with Flash Player 7. The second link didn't look like it had any solution. The third link shows how bad the bug is, and I'm well aware this was part of the problem. You have to close the browser to kill the download if you get stuck downloading an flv because you didn't properly kill it. However, if you call pause() first (which people assume, incorrectly, that you shouldn't have to do), then close(), then set the NetStream to null and then wait at least 250ms (I recommend 500ms) to play the next stream, you're good to go no matter what the MIME type is on the server. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

First tip: use the video and sound classes instead of net stream. Embed an 'empty' video object in your library with a linkage id. When you want to kill the stream, attach this video which will force the player to close any streaming connection. Then do what Steven said - and null out the stream elements. This will force it to close out. I've seen the streams still stick around with 'just' pausing, closing and nulling out the stream connection. The only way I'm pretty sure it will work every time is by attaching this dummy vid. - jon ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
RE: [Flashcoders] Netstream fails to close
FYI, When I post to this list I'm openly and honestly explaining my situation. I would never suggest that someone with as much experience as yourself 'pulled code out of their ass'. I have a fair bit of experience myself and it wasn't working for me. The links I included were simply to illustrate that others had the same difficulty. No they didn't have the answers, or I wouldn't have needed to post here asking for help. I was calling ns.pause() nz.close() I wasn't setting the object to null or waiting x milliseconds. I didn't want to re-instantiate the object. A delay was something I was considering. What it turned out to be was that in some other class in the same sequence of events the NetConnection object instance was having it's setServer method called *before* the ns.pause() and ns.close(). I rearranged the code and it worked. Streams terminate as they should. Client is happy. Seriously, thank-you for your help, I do appreciate it. There's no need to get upset mate.
