AS3.0 and Screen Extension to a second screen

[stratis63]

Dear Friends

I need help for an outsourced project,

I have an application that runs on a PC and tis connected to a videowall,

what the developer has to do in order to have the operator console shown on the operator pc  while the extension (HDMI connection) shows only the end results without the operator selections

the developer does not know  how to do the screen extension , Any hints?

Hi again.

According to this answer by the user from StackOverflow called VC.One:

FLV Component is sometimes glitchy with some re-plays (example: after some loops the video freezes, then plays normal after a few seconds). I think it depends on encoder settings when outputting the video file.

Then he suggests another approach:

You might prefer using the NetStream and Video API to handle video playback.

I've run a test here using his solution and it seems that works.

I've reorganized his approach like this:

AS3 code:

import flash.media.Video;
import flash.net.NetConnection;
import flash.net.NetStream;
import flash.events.NetStatusEvent;
var video:Video;
function start():void
{
    video = createVideo("assets/background.mp4", 0, stage.stageWidth, stage.stageHeight, processMetaData, videoStatusHandler).video;
}
function createVideo(path:String, index:uint, w:int, h:int, metaDataHandler:Function, statusHandler:Function, autoPlay:Boolean = true):Object
{
    var vid:Video;
    var nc:NetConnection;
    var ns:NetStream;
    var metaListener:Object;
    // setup Video object and related Net Stream/Connection objects
    vid = new Video();
    vid.width = w;
    vid.height = h;
    addChildAt(vid, index);
    nc = new NetConnection();
    nc.connect(null);
    ns = new NetStream(nc);
    vid.attachNetStream(ns);
    // metadata handler to correctly display video
    metaListener = new Object();
    metaListener = {onMetaData:metaDataHandler};
    ns.client = metaListener;
    ns.addEventListener(NetStatusEvent.NET_STATUS, statusHandler);
    // play video file
    if (autoPlay)
        ns.play(path);
    return {video:vid, netConnection:nc, netStream:ns, meta:metaListener};
}
function processMetaData(inData:Object):void
{
    //check metadata like width, height, duration etc.
    //trace("duration is: " + inData.duration);
}
function videoStatusHandler(e:NetStatusEvent):void 
{
    if (e.info.code == "NetStream.Buffer.Empty") //buffer is empty when video ends...
    {
        // rewind and play again.
        e.currentTarget.seek(0);
        e.currentTarget.resume();
    }
}
start();

I've sent the files to your email.

Please let me know if it fixes the issue.

Ι ll check. Tks but did you let the video lppp till the end a few times to

see if it workimg?

[JoãoCésar]

Yes. I certainly did.

It looped seamlessly.

I gave it to my developer but after following your advice the flicker is

still, on, I am not sure how to fix my developer is not very cooperative

and the event starts next week.

Its a bit better in terms of flickering contract but the bug is still there,

[stratis63]

here is what he returned but it seems they still flicker

Better less katency but still flickers

I'm sorry about this issue.

It really seems to be some bug with video playback.

What about placing a still image with the first or last frame of the background video behind the actual video? I think there's a good chance of hiding the white blinking from the users attention.

Also, there are two FLV components: FLVPlayback and FLVPlayback 2.5. Have you tried both? Is the result the same?

Alternatively, you should consider reporting this bug:

yes we tried both
