Flex :: Detect When A Remote Client Has Started/stopped Streaming Video Over His NetStream With RTFMP ?
May 1, 2011
Am building a video chat application and i was wondering if there are any native events for the NetStream that fire,that can help in detecting when a remote client starts/stops streaming video over his outgoing stream (NetStream) to which the other client has subscribed over P2P/RTFMP in AS3 ?I maybe able to dispatch custom messages since the two clients are already connected, but i don't want to add the extra overhead.
So I built a videochat client that uses the adobe stratus protocol. Its very simple and just connects two users. However, after about a minute of video chatting the clients freeze and the browser crashes.what might have caused this? Is there some sort of cache that I need to clear every so often or a possible memory leak? I am not sure where to start
I'm trying to create a 2-way videochat. Your own webcam shows perfectly fine, but the other doesn't. I used this page as an example: [UTRL]
Following the steps on the page doesn't seem to work for me. I exchange the peer IDs via PHP. I make my Flash visit a page, which stores the peer ID in the database using a POST request. To fetch the peer ID of the partner, I use PHP sessions, which store both your ID, and that of your partner. I can then use these variables to visit another PHP page, which echoes the partner's peer ID. Both are the same as in the database, so there's nothing wrong with that.
The NetConnection:
Connection = new NetConnection(); Connection.addEventListener(NetStatusEvent.NET_STATUS, CheckConnect); Connection.connect(RTFMP + DevKey);
At a certain point in the app flow, a m4v video is streamed from a remote location via rtmp. This works well, except for two little problems:
1. In very rare cases, the video starts playing, but you see no images and only hear the audio. Seems like this happens more often with Chrome, but that is only a guess.
2. In the first frame or so of the video, you hear a noise in the audio. It really is very short, but still a nuisance. This chirp is not there when viewing the same video with VLC or QuickTime player. It IS there when viewing with the Windows Media Player.
Are there any known problems with codecs and the flash as3 video streaming (via NetStream/NetConnection)? The video is composed by using the ffmpeg library (one mess of a library, I can tell you...) to bring together a live-rendered video (using a 3D Engine) and a pre-created *.wav (which does not have the chirp).
Is there something i can check to see if a NetStream Video is a live stream? I have a DVR app, need the player to snap to live point (if it is live - seek(100000) ? or start from the begining if a recorded video - Ideall a boolean if the stream is live or not...
I'm sure this is a simple question, but I just can't crack it. In my video player I want to detect if the current status is playing or paused. But I can't figure out where this info comes from. Is it a property of the ns object?
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 want to create movement in a movieclip when an arrow key is pressed. I want the movieclip to start moving and not stop until a hitTest recognizes a collision with another object and then tells it to stop. I want the key to only have to be pressed once to start movement and not have to stayed pressed down. How would I do this?
I´m having problems with h.264 in Flash. My idea is streaming a h.264 video from Red5 to a Flash client with ActionScript 3 or 4. The original code supports streaming video in .flv format with Sorensen and I would like to support .flv format with h.264 encoding.This is my original code:
I notice that, when I pause the video, the event "NetStream.Buffer.Flush" is triggered. And according to the language reference: "Data has finished streaming, and the remaining buffer will be emptied.", I have to re-buffer it, right? However, also according to the reference, it shouldn't stop buffering:
Starting with Flash Player 9.0.115.0, Flash Player no longer clears the buffer when NetStream.pause() is called. This behavior is called "smart pause". Before Flash Player 9.0.115.0, Flash Player waited for the buffer to fill up before resuming playback, which often caused a delay.
I'm using Flash Professional to do the debugging, and the traced version number is: MAC 10,0,22,91, and it appears for both FMS4 and red5.
I have created a FLV video player using the AS3 flash.media.Video object (not the FLV playback component) and I am trying to listen for meta events and Cue Points embedded in the FLV video but I am not receiving any when I trace the movie. The cue points are not being created dynamically, they are in the FLV video.
Video embed code: // Initialize net stream nc = new NetConnection(); nc.connect (null); // Not using a media server.
[Code]....
Is there anything I am missing have wrong to capture events from my net stream?
I have a Flex/AIR desktop application that connects a local camera and microphone to a NetStream for delivery to a Flash media server.However, I would also like to archive a copy of the outgoing stream locally on the filesystem. Is there any access to the actual bytestream of a NetStream object (even in the dreaded mx.internal namespace) that I could turn around and feed to a FileStream for the local archive?
I'm new in the mobile app development and I'm trying to do a simple online radio app using flash builder 4.5, but every time I try to play audio from a remote site (stream) it just not work. I've done different test, and when I use a local audio files everything works flawlessly.
I have a Flex application that connects to a BlazeDS server using the StreamingAMF channel. On the server-side the logic is handled by a custom adapter that extends ActionScriptAdapter and implements FlexSessionListener and FlexClientListener interfaces.
I am asking how can I detect which "flex-client" has closed a connection when for example the user is closing the browser? (so I can clean some infos inside the database)
I tried using the following:
1. To manually manage the command messages:
@Override public Object manage(final CommandMessage commandMessage) { switch (commandMessage.getOperation()) {
Some time streaming is working fine and even in Admin console i see the bandwidth Grapgh is growing up due to no. of connected usersbut automatically it happen streaming is stop and bandwidth graph is going down till zero then i restart to FMS then streaming goes smoothly and working fine.before restart i check FMS services it is started and also encoder is connected when i restart it goes smoothly.What happen to FMS i don't know and i don't find any error in FMS log how to stop streaming even FMS is connected and started
If you do a manual start of resizing with startResize(EdgeOrCornerString) you have to set EdgeOrCornerString. But how to detect which one Edge Or Corner has been clicked from inside (NativeWindowBoundsEvent) resizing handler? event.type gives only 'resizing', there is no edge or corner specified. Is it possible and if yes, how?EDIT: I want to do custom resizing of NativeWindow, and need to know from which corner or edge user has started resizing operation.
I am trying to build a client-to-client streaming program - client 1 has a webcam and client 2 will connect to client 1 and be able to view the webcam. Is this possible using 2 swf clients? Can someone point me in the right direction as to what commands would be used to connect the two clients. I have tried: binary sockets Connect() where each clients points to the other and they both time-out NetConnection to try to point each client to one another to establish a connection, but no luck with that either; this seems more oriented towards streaming content to a flash media server rather than to another flash client.
I've got a feature-heavy video player for a client that needs to do pretty much EVERYTHING that flash video can do. Included in the to-do list is bandwidth sniffing for dynamic video switching, which I've managed to make happen using SimpleClient, a custom netstream client class that can pump out the the users bandwidth(see below). The problem with this client is that it didn't include an onMetaData function that can give me all the stats on the streaming flv. In short, does anyone know how to add that functionality to the following .as file? Or, perhaps, does someone have a netstream client that DOES have all the bells and whistles?
How to send a video data stream from one side written by java to another side written by flex and then display it? I just know that on flex one method is to use netstream class get the real-time video stream and bind with a videodisplay to display it. But which class I should use to send this video stream in java and which class I need to use in flex to receive this flow and pass it to the NetStream class?
where to start looking if I want to try and broadcast a live webcam on a webpage client to server to browser?
I want to be able broadcast a live webcam from a machine in location x to a remote server at location y and for the server at location y to display it on a webpage.

I'm trying to add a custom callback handler to a NetStream client in a p2p application. The problem is, when I add such a handler, the NetStream Client doesn't function as it did before. It seems the NetStream.client object is changed. I know the default object is this. But changing the client to this doesn't solve the problem.The remoteControlStream, is the incoming stream. And the localControl stream is the stream being publishedThis is the localControlStream that's being send by the peer, and received as remoteControlStream:
private function initLocalControlStream():void{ localControlStream = new NetStream(nc, NetStream.DIRECT_CONNECTIONS); localControlStream.addEventListener(NetStatusEvent.NET_STATUS, localControlHandler); localControlStream.publish(myPeerID+"control");[code]...
The onPeerConnect method of the localControlStream doesn't get called when I connect when the above handler is added. When I remove the that handler, the onPeerConnect method gets called.
How do i reset netStream.time for a streaming .flv that was intiatied on the server side? It just keeps incrementing on me even after the streaming .flv is done playing.
