How Do I Get Cam Stream To Appear in FMLE Using iGlasses Software?

How Do I Get Cam Stream To Appear in FMLE Using iGlasses Software?

Hi Roger,
Thanks for your reply and my apologies for taking longer than hoped to respond. The problem I'm having is that the cover art shows on my iPad (e.g. for "Meet the Press", a weekly American news programme), but it doesn't in either iTunes on my Mac or (consequently) my iPod Nano.
I'm not sure I understand why the image, if it's embedded, would appear on one device but not on another for iTunes?
I tried going to the iTunes store and dragging the cover art across to iTunes on my Mac, but it only brings the link across (rather than the image).
Any help you could provide would be most appreciated!
Thanks and best regards,
Tony

How to record a live camera stream inside Adobe Media Server?

I am using Adobe Flash Builder 4.6 with Adobe Media Server Extended 5. I am streaming my webcam in Adobe Media Server ("rtmp://localhost/live") successfully. I need to record and save this live video inside Adobe Media Server.
Could you suggest me how I can record a live webcam streaming inside my server?
Thanks in advance

How to add live camera to my website?

Hello,
I have a live video stream here:
http://sketchburger.dyndns.org
Username: sketchburger

I want to show that video stream on my iWeb page. Any idea how to do it??
THANKS!

Hello, Wyodor. How is everything in Dordrecht?
When I visit the sites that you and Alan515 mention in your posts, both Safari and Firefox lock up, requiring a forced quit.
Maybe you can help me try a different approach. I use Evocam to upload images from my Panasonic webcam on a specified interval (refresh rate). The filename assigned to each image is "webcam.jpg" and the images are deposited via ftp to the same directory on my hosting company's server as the web page where I want the image to appear.
A sample HTML file is supplied with Evocam for displaying - and automatically refreshing at a specified interval - a webcam image:
<HTML>
<META HTTP-EQUIV="refresh" CONTENT="60">
<META HTTP-EQUIV="expires" CONTENT="0">
<META HTTP-EQUIV="pragma" CONTENT="no-cache">
<HEAD>
<TITLE>EvoCam Example Page</TITLE>
</HEAD>
<BODY>
<CENTER>
<SMALL>
Powered by EvoCam
</SMALL>
</CENTER>
</BODY>
</HTML>
Note that where you see the familiar white question mark on a blue background in the sample code, above, there is actually this line: IMG SRC="webcam.jpg" (with the surrounding left and right arrows; I can't include them in this post).
I posted that code into a snippet and the Evocam promo text appears on the published web page. It refreshes at the specified interval (60 seconds in this case), but the image (webcam.jpg) does not appear. Instead, I see the aforementioned question mark.
Any ideas what I'm missing?

How to play live Video Stream with Flex?

I'm trying to get Flex Builder 3 to play a live video stream with Flash Media
Server and Flash Live Media Encoder.
I'm able to stream pre-recrorded (vod) flvs in flex from flash media server.
I'm able to stream live video using Flash/FMS/Flas Live Media Encoder, but not
with Flex.
This code streams pre-recorded Video on Demand flvs, but not live streams:
If I change source to "rtmp://localhost/live/livesream.flv, I get nothing.
What am I doing wrong?
<?xml version="1.0"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
    <mx:HBox>
        <mx:Label text="RTMP FMS 2.0"/>
        <mx:VideoDisplay
            autoBandWidthDetection="false"
            source="rtmp://localhost/vod/Legend.flv"/>
    </mx:HBox>
</mx:Application>
Oh and sorry for the double post. I didn't know there was a seperate FMS forum.

That worked! Thanks *very* much. Stupid of me to forget to set the live attribute to true. Also removed the .flv. BTW: what video component do you prefer?
Here's the working code:
<?xml version="1.0"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
    <mx:HBox>
        <mx:VideoDisplay
            live="true"
            autoBandWidthDetection="false"
            source="rtmp://localhost/live/livestream"/>
    </mx:HBox>
</mx:Application>

How to enable live audio streaming in FF running Windows 7

I am unable to listen to live audio streams, please help !

Which plugin is used for those streams?
Your More system details list shows the WMP plugin and the Flash plugin as commonly used plugins to play streams.
Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.

How to input live video streams to a powerbook?

How do I input multiple video cameras into a Mac (over Thunderbolt)?
And what devices would you recommend?
I would like to be able to have two or more cameras feeding into a Macbook Pro simultaneously. I'm looking at making a MaxMSP app for a video artist I know, to replace an enormous box of hardware that he put together years ago. The app & the output are not a problem, but as most of my other work is in audio, I have no idea if it's possible to have multiple cameras feeding into a Mac. These will be SDI cameras (or older devices running through convertors).
Thanks in advance....
David

This topic has been aroundfor a decade and there is one thing we've learned from hundreds of similar posts: do not reoly on the captured video in your computer to be your only copty of the program. Drives fail. Clients trip over power cords. Firewire is a non-locking connection, totally unreliable. Even in the days of ultrareliable videotape, we oftne ran a VHS protection copy off a video/audio loop.
Have a tape or chip backup recording of your video feed.

Broadcast, live stream?

Hello. I have a few questions regarding broadcasting live video streams in H.264 encoded format. I am new here and have little knowledge about the topic. What I am interested in is how can I broadcast (multicast?) live video streams over the internet to multiple viewers? I have video content on a HDD, encoded in H.264 which is constantly updating (I add new files, remove old ones and so on, kind of like a TV channel or Internet Radio but with video), I need to feed that content to a live stream server somehow. It should not be an "On Demand" stream, but "live". What software do I need for this? What do I need to broadcast my so-called "live TV" to end users and what software should I use to auto "feed" the server with new content? If you have any thoughts or can give me links to helpful resources I would appreciate it a lot! Thank you!

I already took a look at that software. I don't sure if it fits my needs. Lets say I have a video source which is an uncompressed live stream. I need: to capture that stream, compress it using H.264 encoding, then rebroadcast it. The time buffer I have is 8 hours (I can broadcast the compressed stream after 8 hours after getting the original stream). Now, how do I do it?

Online camera streams not working

Hey
When I go to a website to watch a live camera stream it doesn't work. It only keeps loading for ages and nothing happens. I've tried several websites. I tried Chatroulette and even that didn't work. Apparently it doesn't work to load my own cam either. It's not my firewall as I've already checked that. Does anyone know what the problem might be?
Thanks

I didn't even know what Chatroulette was but I went to the site and I could activate my camera and mic, at least. Had no idea, and didn't hang around long enough, to see if anyone popped in.
Do your camera and mic work in Facetime, Skype, etc.? Can you see others images using those servers? Could your ISP be blocking access?

Why don't you use several layers with appropriate alpha properties, and move these layers according to the mouse events?

Can I stream a live camera to Apple tv?

Is it possible to stream a live video camera to Apple TV? I want to be able to easily send a feed from a video camera when I videotape a musical to a remote room with a TV where the actors and director will be. There will be wireless network and I can possibly get a hard wired ethernet connection. Could I hook up the camera to a MAC and have it send to Air Play for Apple TV to see it?

You can Airplay from a Mac to the Apple Tv, and you can mirror the Mac's screen through airplay Mirroring. so whatever is on the MAcs screen can be seen through the Apple Tv.
If you have the Camera feed on the Mac's screen, then you should be able to see it.
How you connect the camera to the Mac, will likely depend on the camera and whether or not there is software to directly allow this over say USB or Thunderbolt for the camera you'll be using. You'll have to contact the camera manufacturer to find out.
Alternatively a video capture card would also work depending on the camera's possible output connections.

How to understand live stream is online

Hi,
First sorry about my english, i search my problem, but i couldnt find my answer,
We have more then 80 live stream videos. More than 20 PC with capture cards, send cam streams to FSM with FME,
Problems,
PC can crush, capture card can crush, fme can crush, camera connection can crush,
so with below code, i can unterstand if FMS server is alive, "NetConnection.Connect.Success"
but is my stream alive? How i can understand "1test1" is alive,
for example i can unterstand with onMetaData info, if there is no meta info, no stream,
but i am a noob, what is the true way to understand live stream is alive, meta info isn't true way i think
i change var videoURL:String ="1test1" to a false value
but no error i get, it never says "NetStream.Play.StreamNotFound":
my goal is, i will make a web page, it will find all livestreams from xml, and cheack them, so systemadmin will see problem easly,
last question, if there is a camera problem, livestream gives a blank black screen, can i understand automaticly this screen
var videoURL:String ="1test1"
var nc:NetConnection = new NetConnection();
nc.client = this;
nc.connect("rtmp://myFMS/live/");
nc.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
function netStatusHandler(event:NetStatusEvent):void{
trace(" trace netStatusHandler: " +event.info.code);
switch (event.info.code)
case "NetConnection.Connect.Success":
connectStream();
break;
case "NetStream.Play.StreamNotFound":
trace("Stream not found: " + videoURL);
break;
function connectStream():void
var vid:Video = new Video(640,480);
var ns:NetStream = new NetStream(nc);
ns.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
var meta:Object = new Object();
meta.onMetaData = function(info:Object){
trace("metadata: duration=" + info.duration + " width=" + info.width + " height=" + info.height + " framerate=" + info.framerate)}
ns.client = meta;
addChild(vid);
vid.attachNetStream(ns);
ns.play(videoURL);

thanks, now i am able to understand what's your requirement.
first you create a sample live chat application. just for testing purpose.
1- create video object.;
2- create camera object;
3- attache camera object to video object;
4- create a button and register a event and listener function write below code.
5- download adobe.image.PNGEncoder class
hope, you can capture photo from video object into you testing application
package
    import com.adobe.image.PNGEncoder;
    import flash.display.Sprite;
    import flash.display.DisplayObject;
    import flash.events.*;
    import flash.display.Bitmap;
    import flash.display.BitmapData;
    import flash.media.Video;
    import flash.media.Camera;
    import flash.geom.*;
    import flash.net.FileReference;
    import flash.utils.ByteArray;
    public class SavePng extends Sprite
        private var cam:Camera;
        private var video:Video;
        private var ab:FileReference;
        public function SavePng()
            cam = Camera.getCamera();
            cam.setMode(800,600,25);
            cam.setQuality(0, 90);
            video = new Video(1024,768);
            video .smoothing=true;
            video.attachCamera(cam);
            addChild(video);
            btn.addEventListener(MouseEvent.CLICK,saveImage);
            ab=new FileReference();
        private function saveImage(evt:MouseEvent):void
            var count:int = 0;
            var scaleW:Number = .5;
            var scaleH:Number = .5;
            var m:Matrix = new Matrix();
            m.scale(scaleW,scaleH);
            var bmd:BitmapData = new BitmapData(320,240,true);
            bmd.draw(video);
            var img:Bitmap=new Bitmap(bmd);
            img.x=250;
            img.y=200;
            addChild(img);
            var ba:ByteArray = PNGEncoder.encode(bmd);
           ab.save(ba,"sushil.png")

Media server and Media live encoder running, but how do I view my stream?

Ok. This is the first time I have ever used these two programs. I got the Media server running and connected and the Media live encoder streaming and connected to the server. I have not been able to test the stream to see if it is working correctly however, judging by the logs, it seems to be working. What I really want to know is the simplest instructions on how to view the stream from outside of my network, as it is broadcasting over the net. I am trying to do a live stream.
With just these two programs running is there a link I can go to that it will automatically play the stream back?
What exactly to I need to do now to be able to give someone my link over the net so they can watch the stream?
Do I actually need a server to put the /applications/live folder onto?
Thank you!
(ps I have been reading the adobe documentation on this but I'm still confused)

I am certainly no expert as I have just started working
with this myself. But I will try to help.
To view the stream you need a client. As started in the Flash Media Server Development Guide:
You can use any of the following clients to play video streamed from the live service:
Flash Media Server sample video player (RootInstall/samples/videoPlayer)
Flash FLVPlayback component (fl.video.FLVPlayback)
Flex VideoDisplay component (mx.controls.VideoDisplay)
Any custom-built application that runs in Flash Player, AIR, or Flash Lite 3
You can pick up this link at http://help.adobe.com/en_US/FlashMediaServer/3.5_Deving/WS5b3ccc516d4fbf351e63e3d11a0773cf ae-7ff7.html
I have a very basic example of a custom-built player that does work - I'm running FMS Dev (localhost) and a webcam. Let me know if you need the example.
Good luck. I hope more experts will start to post help, as I am struggling with some things myself.

How to play live streaming in windows phone 8.1 silverlight app?

Hi,
I am developing a windows phone 8.1 silverlight app. In my I want to show live streaming youtube channel , I think it is not possible,
Actually that youtube channel is a television channel , I want to stream that live tv in my app.(I tried to load youtube channel in webbrowser in iframe tag but it is not opening)
Anybody help me how to play live tv or live streaming in my app,
Thanks..
Suresh.M

Hello,
You will likely need to write a custom
MediaStreamSource that can access the media stream and parse it. Windows Phone supports h.264 natively and as long as the site serves up a media stream that contains h.264 frames you can parse it and have our built in decoder decode and display it. You
will need to have intimate knowledge of the streaming protocol used by the website that you are trying to play. You must also make sure that the website is not using protected content. IANAL so I would recommend that you have your local law professional
(lawyer) review the licensing of the website that you are attempting to connect to and stream from before continuing your development. Your lawyer can make sure make sure their licensing allows you to do this.
I hope this helps,
James

How to create Live and Archive Streaming URLs??

Hello Pros,
I am new to QT Streaming Server, and how it is setup and delivered. Please take it easy on me. Here are my questions.
Our school has been using Helix (Real) Server to deliver some video content via Live/Archive streaming video. The school will be changing a format to QuickTime Streaming server to move away from Real. We would like to deliver MPEG4 file via Live Streaming and archive. We set up QT Streaming Server and we can deliver video now.
How do you create and display URLs on a webpage to share live and archive movies? In RealServer, you can list URLs with live and archive, and RealPlayer opens separately and play movie. The videos are lectures so the website will have list of lecture links as we record every week.
If I click this link, a RealPlayer opens and start playing. Currently, I know that “sdp” file is assigned under RealPlayer. When I changed it to QuickTime Player, the player does not open to play movie. Is there way for me to setup URL to open it in external player? We are not interested in making the movie playable inside webpage. We would like to let viewers have option to stretch the movie player to view larger image if they wish. Strange thing is that when the live movie is played in RealPlayer, the image size is smaller that what we stream (320x240). How is it possible? I am confused…
How about archived streaming URLs? I have seen sites with embedded movie in the webpage, but how do you make links that when a viewer click the URL, it will start QuickTime Player externally instead of open it in new webpage? Is this possible? In RealServer, you can use “ramgen” code in a part of URL to open RealPlayer to play a movie.
Any help will be appreciated it.
Thank you.
