ActionScript 3.0 :: Using The NetStream Class?
Aug 6, 2010
I have a few questions about the net stream class..Lets start with the first one I have a netStream class that is basically set to default property values I am loading a video file off the local hard drive.Now once this video starts playing, I get NetStreamEvents constantly firing.. extremely rapid pace.
NetStream.Buffer.Full
NetStream.Buffer.Flush
NetStream.Buffer.Full
[code]....
It just keeps filling up and then flushing itself, but the video plays smoothly so to the end users nothing is wrong..

I'm trying to play an FLV on a video instance on the stage called my_video. This works as frame code the timeline, but when I use it as a class it loads the video but gets stuck on the first frame.
Here is my code
Code:

private function loadVid(mc:MovieClip)

I am trying to load video using NetStream. I am able to do this by using the Video Class, but is it possible with the FLV Playback? I would like to add a seek bar so people can scroll the video if they want to.
I know the FLV Playback Component has this built in so I would use it BUT I can't load a stream to the FLV Playback, I can only set it's source. This works fine, but it doesn't allow me to unload it, the sound keeps playing, which is why I ended up using the NetStream instead.
So I have 2 questions. 1) Is it possible to load the NetStream to the FLV Playback component? 2) If not, how do I add the seek functionality to my Video Class?

I am trying to use "maxPauseBufferTime" property in NetStream class.I am using Adobe Flash Pro CS3. I have defined an object by the name nsStream of NetStream class. When I write nsStream and put a dot next to nsStream it shows me a drop down list of the properties of NetStream. However it doesn't show me maxPauseBufferTime property. I also tried the same with Adobe Flash Pro CS5. Even there the drop down list for nsStream doesnt show me the maxPauseBufferTime property.The adobe help page (first link that shows up when I google for as3 NetStream. Forum rules doesn't allow me to post the link here) indicates that this property is part of NetStream class.

I'm building a video chat in flash and everything works really well, except for the part where I'm trying to detect if the other user is sending a working video stream. There's a couple of reasons why the other user isn't sending video.
-The other user got no camera
-The other user got a camera, but the camera is currently being occupied by another application(Skype, Photo Booth, Google Talk, etc.)
-The other user got a camera but hasn't allowed the use of his/hers camera.
(Other unexpected problems I guess...)
So how do I detect if the stream I receive from the other user is a black stream(because of the reasons above) using the NetStream class? The closest thing I have came up with is by adding a timer that polls the currentFps() function from the stream I receive from the other user. But so far this seems pretty unreliable because I might get currentFps() == 0 and show an error because of this even though I actually got video from the stream in some cases. The reason for this is because I poll the API every 4 seconds for the currentFPS function and let's say at 00:00:04 I get "no video" according to the poll but at 00:00:05 the video kicks in, and therefor I need to wait until the next tick until the error message disappears
This is what my current poll looks like
function subscribingStatusPoll(e:TimerEvent):void {
if (subscribingStream.currentFPS == 0){
error.text = "No video found from the other user...
} else {
error.text = "";
}}
This is the only hack I that I can come up with to detect this, but this is unreliable and I actually would prefer a way to instantly detect if the stream I receive got a working video attached to it.

I'm making a small video players in AS3, and I've found that after calling NetStream.pause() or NetStream.togglePause(), no status messages are being fired any more.If I click the "pause" button while the video is buffering, I never get the Buffer.Full message.Here is some code:
_connection = new NetConnection();
_connection.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
_connection.connect(null);[code].....

I am working on an app that will take a snapshot of an rtmp stream of an archived video, save it to a file, and ExternalInterface the file name to the hosting page to javascript it up for display.
I actually have all pieces working great. The only time an error is thrown is when I pause the video, seek to somewhere, and then try to take a snapshot. Then there is a runtime error of:
SecurityError: Error #2123: Security sandbox violation: BitmapData.draw: mySwf.swf cannot access rtmp://myFlashServer/myApp. No policy files granted access.I've seen post after post of suggestions and have tried them, but without success.
I have the crossdomain.xml and my FlashMediaServer security setup fine (it is actually working, except for this one glitch). It just seems to be the pause-then-seek-then-BitMapData.draw() combination which is creating issues.
Another weird thing: after the error is thrown, if I resume the stream and take a snapshot, it works flawlessly again.

A NetStatusEvent with info.code of "NetStream.Connect.Closed" is dispatched by NetConnection when a NetStream is closed. This seems kind of weird, shouldn't the NetStream dispatch the event? how do I know which NetStream has been closed if I have more than one running (which I do)? I need to know so I can cleanup the now dead stream.

I'm currently on a project where to build a site with with several video-clips being played and reached from a menu. The video-files will be in FLV-format.I've done some video solutions in flash a few years ago but this time it will be in CS5 (AS3) and I'm not sure which solution that will suite this project best.The video clips must run smooth and I guess we'll need some cuepoints and buffering to make the transitions from the user inputs smooth. I think they need some MovieClips on top the videopart as well for navigation/information.
Should I use the NetStream-way or use the FLVPlayback-way? I got some demo-video-files yesterday and I ran an example using the FLVPlayback-method and it showed up smoothly but is this the way to go?Why would you use either NetStream or FLVPlayback?

I'm trying to figure out how I can add a seekbar to my netstream.I have the duration of the flv through metadata and the current time of the stream, but I can't understand how I should connect them to pass a position to a seek handler. And allso to be able to drag the handler to positions in the stream.

Is it possible to add cue points using as3 and I will not be using FLVPlayback component.
I want my flv or netstream object to call a fucntion after 7 or 16 second or at any specified time during playing. i found addAsCuePoint the only way to do it.
If there is any other way to accomplish this task then i will not be using cue points..

In a Flex NetStatusEvent of type NetGroup.MulticastStream.PublishNotify, you get the String name of the stream in e.info.name
The name is what the publisher specified in the .publish ("") method. But in a NetStatusEvent of type NetStream.Connect.Success, there is no such property. Instead, the whole NetStream object is available through e.info.stream
How the heck to you get something as basic as the name from the NetStream object? e.info.stream.name does not exist. I must be overlooking something very simple.

I'm creating a video chat app using Flash Media Server 4 and Flex, using RTMFP for peer-to-peer.No matter what I try, I cannot mute a user's NetStream. I tried receiveAudio(false) and that does not work. I tried capturing the stream SoundTransform and setting the volume of that to 0, that does not work.I tried setting the mx VideoDisplay volume to 0 and that does not work.I can set the alpha of the VideoDisplay, so its really strange that I cannot set the volume.BTW, I am not trying to mute the mic of the user who launched the app, that I can do. I'm trying to mute one of the other users stream in the Flex app, that way the app makes it possible to not hear people who are perhaps being offensive.

The code above is my standard preloader for swf, I use it since long time and its all working, I managed above the script another one that load the flv?s that I use in the array. The two are working but my need is that the container only start to play the module after all the flv?s have been loaded to the cache.
One thing to note is that in the second script the array is playing the flv?s when should be only load, I?ve try to give a ns.pause(); but if I do that the array dont get to the end of it.

i've a very strange problem with a NetStream Buffer only in Internet Explorer (flash player version 10,0,32,18). When I connect to a netstream I use this:
var videoOpe:Video=new Video();
var stream="name live stream";
var nsOpe = new NetStream(nc); //nc is an active netConnection
nsOpe.bufferTime=1;
nsOpe.client=this;

Currently I'm using a rtmp server to streaming a video (m4v format), and now I need to set a cuePoints to call this one.
The problem is,
I'm using a simple video playback with NetStream and NetConnection, till here its okay, the video is streaming correctly, now appears the necessity to show some graphics in middle of the video.
How can I set the cuePoint name? addCuePoint()? The simple video player support it?

I have a video with 2 embedded cue points (event). The video player uses NetStream and is NOT a FLV Playback component. [code]...
That action will also do the loadMovie, so I know the loadMovie part works. But since there are 2 cue points the loadMovie fires with each cue point... not what I had in mind.
I just don't know how to get the loadMovie to fire outside of that function. I've tried this[code]...

I have flv's in the new H264 codec which apparently cannot have meta data cue points embedded like you would using Flash video encoder. I'm using Netstream in a custom player. Any suggestions how I would go about using XML cue points with Netstream? How would the playhead time trigger a search of the xml file?

I am going to be upset if you cannot use addASCuePoint (or a similar method) with the netstream object.Ive done a bit of googling and that is what I am seeing. Apparently it only works with the FLVPlayback component, but I havent seen any official docs stating that. Anyone have experience with this?

As you can see, after all the items in the Carousel have loaded, a function called fadeItemIn() is called which displays each of them one by one. I am looking to call a small "swoosh" particle effect flv I made in AfterEffects so that as each item tweens in, it instead looks like it is sparkling in from the left.
The problem I have is that using the code below, the swoosh.flv file tends to freeze before it finishes. In this case the swooshIn() function is called three times because there are three items being loaded into the Carousel.
I am wondering why the FLV freezes when multiple instances of it are loaded through AS3 using NetStream.
Code:
private function fadeItemIn(item:CarouselItem):void {
trace("fadeItemIn");
this.tweens.push(new Tween(item, "altitude", Regular.easeOut, item.altitude, 2.5, 0.50, true));

I want to utilize the FLVPlayback component so I don't have to create my own skins and the documentation says the FLVPlayback class "wraps" the VideoPlayer class and ALL the methods/props available in the VideoPlayer class are available to the FLVPlayback class, BUT I notice the FLVPlayback class doesn't inherit or subclass the VideoPlayer class and some of the methods/props for the VideoPlayer class generate errors when utilized by the FLVPlayback class.
In short, I want to take a NetStream instance that has the stream I want to utilize and force that on the FLVPlayback instance. I can get it to work with the VideoPlayer instance BUT NOT the FLVPlayback instance. I don't want to set the FLVPlayback instance's "source" property with a string as the documentation suggests, I want to do something like:
Code: flvPlaybackComp.attachNetStream(stream); how can I accomplish this? I've seen the "getVideoPlayer" method on the FLVPlayback class and thought that might be a "round about" way of controlling the underlying VideoPlayer instance, but haven't gotten that to work properly.
