streaming prerecorded files

Report · Jun 25, 2009

hi,

i want to stream like a tv channel a list of files.

in this case i have 6 files:

s1.flv - s2.flv - s3.flv - s4.flv - s5.flv - s6.flv

this videos are 1366 * 768 pixeles.

this videos are about 15 seconds every one, they are short videos.every video are about 700 kb

in the server inside the application file i have an app name: test nd inside test i have streams/_definst_

/test

/test/streams

/test/streams/_definst_ (here there are the videos)

my main.asc source is:

application.onAppStart = function(){
    this.clientStream = Stream.get("clientPlayStream");
    this.clientStream.play("s1", 0, -1);
    this.clientStream.play("s2", 0, -1, false);
    this.clientStream.play("s3", 0, -1, false);
    this.clientStream.play("s4", 0, -1, false);
    this.clientStream.play("s5", 0, -1, false);
    this.clientStream.play("s6", 0, -1, false);

    application.onStatus = function(info){
        if(info.code=="NetStream.Play.Stop") {
           this.clientStream.play("p1", 0, -1);
            this.clientStream.play("p2", 0, -1, false);
            this.clientStream.play("p3", 0, -1, false);
            this.clientStream.play("p4", 0, -1, false);
            this.clientStream.play("p5", 0, -1, false);
            this.clientStream.play("p6", 0, -1, false);
        }
    }
}

what im trying to do is to stream this 6 files and then loop.

and i have a class in my fla file:

package {
    import flash.display.Sprite;
    import flash.net.NetConnection;
    import flash.events.NetStatusEvent;
    import flash.events.AsyncErrorEvent;
    import flash.net.NetStream;
    import flash.media.Video;

    public class MUAC extends Sprite {
        var nc:NetConnection;
        var ns:NetStream;
        var video:Video;
        var videoURL:String="clientPlayStream";

        public function MUAC() {
            nc = new NetConnection();
            nc.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
            nc.connect("rtmp://localhost/test/");
        }

        private function netStatusHandler(event:NetStatusEvent):void {
            trace("event.info.level: " + event.info.level + "\n", "event.info.code: " + event.info.code);
            switch (event.info.code) {
                case "NetConnection.Connect.Success" :
                    // Call doPlaylist() or doVideo() here.
                    doVideo(nc);
                    break;
                case "NetConnection.Connect.Failed" :
                    // Handle this case here.
                    break;
                case "NetConnection.Connect.Rejected" :
                    // Handle this case here.
                    break;
                case "NetStream.Play.Stop" :
                    // Handle this case here.
                    break;
                case "NetStream.Play.StreamNotFound" :
                    // Handle this case here.
                    break;
                case "NetStream.Publish.BadName" :
                    trace("The stream name is already used");
                    // Handle this case here.
                    break;
            }
        }

        // play a recorded stream on the server
        private function doVideo(nc:NetConnection):void {
            ns=new NetStream(nc);
            ns.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
            ns.client = new CustomClient();

            video = new Video();
            video.attachNetStream(ns);

            ns.play(videoURL);
            addChild(video);
            video.width = 1366
            video.height = 768;
        }
    }
}

class CustomClient {
    public function onMetaData(info:Object):void {
        trace("metadata: duration=" + info.duration + " width=" + info.width + " height=" + info.height + " framerate=" + info.framerate);
    }
    public function onPlayStatus(info:Object):void {
        trace("handling playstatus here");
    }
}

this looks fine, but when i try i run the app, i run the flash file the videos are too slow.

i dont know whats going on. can someone help me to fine whats going on ???

thanks.

I think there is typo in your server-side code , probabaly you might have typed it wrong here because there are not p1.flv,p2.flv ..

I really dont know why they should play slow for you. But i can suggest you try with this code and see if things fine - I am just giving more correct code but dont know whether it will solve slow play which you are seeing ( i.e. flash file video is too slow)

Server-side:

application.onAppStart = function(){

this.clientStream = Stream.get("clientPlayStream");

this.clientStream.onStatus = function(info){

        if(info.code=="NetStream.Play.Stop") {
           this.clientStream.play("s1", 0, -1,false);
            this.clientStream.play("s2", 0, -1, false);
            this.clientStream.play("s3", 0, -1, false);
            this.clientStream.play("s4", 0, -1, false);
            this.clientStream.play("s5", 0, -1, false);
            this.clientStream.play("s6", 0, -1, false);
        }

}

    this.clientStream.play("s1", 0, -1);
    this.clientStream.play("s2", 0, -1, false);
    this.clientStream.play("s3", 0, -1, false);
    this.clientStream.play("s4", 0, -1, false);
    this.clientStream.play("s5", 0, -1, false);
    this.clientStream.play("s6", 0, -1, false);

}

Client-end:

....

ns.setBufferTime(2);

ns.play(videoURL,"live");

See if this works fine for you.
