Webcam live stream encoding

I am developing a Video Streaming Application using Flex (AS 3.0) & Flash Media Server. I would like to know whether it is possible to encode (using H.264 or VP7 or Sorensen spark) the video from the web camera on the fly & stream it to the FMS server without using Flash Media Live Encoder.
Is it possible ?
Please Help...

Asa,
Are you able to share details of what the solution being developed by Adobe will involve, and which versions of FMS it will apply to (an update for 3.0, 3.5 or just a feature of 4.0)
Thanks,
Michael

Protecting Live Stream Encoding URL

We set up a Flash Media Server and we are trying to figure out how to protect our live encoding url. Seems like anyone with a Flash Media Encoder and who knew the location of our server could publish a live stream. Can we password protect this in any way?

Flash live streaming encoder question

Does flash8 pro encode STREAMING video as VP6 or Sorenson?
Non live streaming is VP6, but there seems to be no
conclusive answer as to whether live streaming uses the same
encoder.
I guess not, otherwise something like on2 flix live would
have no reason to exist if you already own flash pro...

The answer was to go back to Wowza. Adobe dropped the ball.

FME encoding live streams

Hi there
I recently got to read the "Stream Live Video with Flash
Media Encoder.pdf" that comes with the FMS3 INteractive server.
Since i am (and was) looking for a video encoding tool for a long
time now a paragraph in the above mentioned pdf got all my
attention.
"Flash Media Encoder 2 can also be tightly integrated into
your streaming pipeline
with command-line control both locally and through a remote
connection."
I'm not sure if i correctly understood, but if i'm not wrong
that means i can plug FME into my existing streams and encode them
before they reach the end-user.
I for instance am using a one-2-many live streaming platform,
where the publisher streams his/her webcam's video to FMS, and a
virtually unlimited number of subscribers can watch it.
Would FME be able to support this kind of implementation, so
i can have the video encoded at any level before the subscribers
are actually seing it? (without having to deploy a desktop
application that the publisher needs to use).
Looking forward to hear your opinions.
Regards
Andy

Hi
Thank you for your anwer. It might not be what i wanted to
hear. However i was looking through On2 products list. I tried to
contact them too for a solution like the one i have explained in
the first post. Unfortunately they did not answer (yet).
Anyone knows if any of the On2 products can be used to encode
the live stream before being published and available to the
subscribers?.
Looking forward to hear from someone ... anyone.

About Flash P2P live streaming from non-webcam sources

Hello, I am a university student. Our lab is attempting to work on a p2p live streaming using flash p2p features. The media source is not from a webcam but a file from a certain server, which is not directly supported by any of the 4 methods flash player offers(posting, direct routing , object replication,and multicast.) As some of the forum threads mentioned, our method is to use NetStream.publish() a stream and use send("callbackname", data) to all subscribers that have joined in a NetGroup. So we can use p2p transmission. Now here are our questions:
1. We know from MAX 2009 that flash p2p camera video multicasting implements pull-push mechanism inside which makes full use of p2p features like buffer map exchange. If we use NetStream.send() API to send non-webcam source data, will it also make use of this pull-push mechanism to spread data among all peers(subscribers) with proper data exchange?
or more detailedly,
I saw the P2P Gaming Libs at flashrealtime.com. It uses DIRECT_CONNECTIONS when creating publish-used NetStream in order to send data with lowest latency. My question is if I do not use DIRECT_CONNECTIONS, than when the NetGroup grow large (1000), will those peers that are not direct neighbors to the publisher in the same group relay data to each other using pull-push via buffer map?
2. I have written a sample app and use send() to deliver data only (NetStream.bufferTime = 0) without camera video and audio. When the publisher sends the data in a "for()" stantence for 20 times, the subscribers can only receive about 8 of them. But when I set a timer and periodically send them(e.g., 500ms), the subscribers can receive them correctly. My questions are: Is the packet loss caused by UDP unreliability? Can this be solved by setting the NetStream.dataReliable = ture? Can this totally be solved by setting a timer? How to set the delaytime property in timer? Are all data sent are orderedly received?
I'm very appreciated if you can answer my questions? thanks.

1. NetStream.send() data is delivered in the order it was sent, whether in client-server, DIRECT_CONNECTIONS, or multicast mode.
2. the lowest latency will be achieved with DIRECT_CONNECTIONS. however, that isn't scalable to large numbers of recipients. the P2P multicast system trades low latency for scalability.
3. there are no plans to support a natural NetStream streaming source that's not a camera/microphone. Flash Media Server can perform that function.
4. you should never need to implement "bitmap exchange"; the object replication system handles all the communication needed to accomplish its function. typically you will divide a file into segments, giving each one an index number. object replication uses ranges internally, so the index numbers should be contiguous. nodes that have indices use NetGroup.addHaveObjects(). nodes that want indices they don't have use NetGroup.addWantObjects(). nodes that have objects will send them to nodes that want the objects. when a node receives an object, it's automatically removed from its "want" set; once the node decides the object is acceptable, it adds it to its "have" set, at which point it can answer requests from other nodes who still "want" it. eventually every node will have all the pieces and not want any. for an example, please see Tom Krcha's articles on using object replication:
http://www.flashrealtime.com/file-share-object-replication-flash-p2p/
http://www.flashrealtime.com/video-on-demand-over-p2p-in-flash-player-101-with-object-repl ication/
5. please see Tom Krcha's articles. for VOD you will probably want to use the "LOWEST_FIRST" replication strategy, as that may allow you to start playing earlier. for general file replication you'll get better sharing if you use RAREST_FIRST.

Using http live streaming to stream data from a Webcam

JavaFX 2.2 includes support for http live streaming: http://en.wikipedia.org/wiki/HTTP_Live_Streaming
How could one create a http live stream from a Webcam and thereby enable a JavaFX application to view and hear the Webcam video in realtime?

Bom Dia Saille,
Eu acredito que o que você tenha hoje seja isso aqui (Desenho bem simplificado):
Hoje o que você tem é o Aplicativo do Medidor + USB Driver controlando o seu medidor. Basicamente, sua aplciação está dividida em três camadas:
Aplicação - Onde estão as funcionalidades principais do programa (interface com o usuário, apresentação de dados, geração de arquivos, etc.)
VISA - Uma arquitetura de Software para controle de instrumentos. Basicamente, ele se comunica com o Driver USB para poder enviar e receber pacotes de dados através do barramento USB.
Device Driver - Intruções de SW de baixo nível para controlar um periférico através de um barramento.
No desenho, eu aponto duas camadas onde você pode tentar atuar para automatizar suas medições:
Aplicação - Você pode usar o VI Server para controlar o Aplicativo do Medidor (Se este aplicativo tiver sido desenvolvido em LabVIEW, o que eu suponho ser verdade). No entanto é necessário saber se o desenvolvedor do produto permitiu isso (Veja Using VI Server to Pass Data Between a VI and a LabVIEW Executable). Outra alternativa é conversar com o fabricante para ver se ele desenvolveu alguma API (Application Programming Interface) para que você consiga controlar o instrumento diretamente.
VISA - O LabVIEW Fornece uma API chamada NI-VISA para poder enviar e receber informações através de diversos barramentos (Veja Serial Instrument Control Tutorial)
É possível acessar o Driver diretamente também, mas eu não recomendo. O resultado não compensa o esfroço!
Espero ter esclarecido suas dúvidas e espero que você tenha sucesso na sua aplicação!!
Atenciosamente.

Live Streaming Using my Webcam As a secruity camera

I'm lost here someone please help, : \ im trying to use my isight as a security camera over the internet so i can watch my dog i just got her.
So the question is what software out there i can use to put my webcam as a camera ( again my powerbook is kinda old im still running on panther so i have 10.3.9 not 10.4 can i work anyway around this) where i can watch live.
Can someone help me i know i need my ip address i have that but when i hook everythign else up where do i go when im somewhere else when i want to look at my live streaming from work to my house? please can someone help me thank you if you can. : )

Hello, keith28
Until we hear back from juanorfrankie, here is my suggestion for your question:
I would like to access the isight using my iPhone.
Can anyone make some suggestions?
If iPhone will can support viewing a streaming webcam page, use EvoCam with your iSight to publish a webcam with streaming video. That would probably be the simplest way to do what you want, but, because I do not have iPhone, so I cannot test this.
See the instructions and FAQs at EvoCam for system requirements and details on how to set up your webcam page.

User Auth. for Live Streaming with Media Encoder 2.5 and FMSS

Hi,
i am currently thinking of buying the Flash Media STREAMING
Server (~995 $) and in order to see if this is the right choice, i
also take a look at the Wowza Media Server for comparison.
I want to support Live Streaming from Events with Flash Media
Encoder 2.5 and for this i'll need a user authentification for
giving access to special publishing Users only. Wowza Media Server
supports a User Authentification by parsing the connecting URL,
witch is delivered by the Media Encoder on starting a Connection,
and therefor grants or denies access to the publishing function.
Only Users with the right Access Persmissions, which is written
trough a password and the onPublish Comand in the url, can publish
Live Streams. Everyone can watch the Live Stream, if no restriction
to the onConnect Command was made.
The Problem in this case is, i will need seperate Application
folders for every user who should be able to start a live stream.
This would be a horrible effort...

Is there a similar way to support authorisation for starting
publishing a LiveStream to the Flash Media Streaming Server, or do
i need the Flash Media Interactive Server?
How can i restrict access to users, who should not be able to
start a live stream on my FMSS?
Thx for your help,
Tobi

Unfortunately no, there isn't. I struggled with same issue
earlier, and we were forced to purcahse the Interactive edition. As
the 'Streaming' version only runs Adobe-signed apps, there is no
way to change things that happen within the onConnect handler.
Furthermore, guys at Adobe haven't provided any possibility for
even simple access control through configuration files for built-in
apps that come along with the Streaming Server edition.

Hi,
Just move your image display control inside the while loop.
Also don't forget to create image buffers to feed your vision functions... Otherwise you may have some strange behavior.

Encode archive of live stream on FMS 4

I thought by what I have initially read that this was possible, but I am not sure.
What we would like to do is create an archive (f4v or mp4) on the FMS 4 server any live stream that is pushed from our endpoints. Primarily as a backup and if necessary - an editable file within CS4 or CS5.
We are at a University and capture lecture powerpoints natively and sometimes need to edit the files. flv is not enough and we would like to take afvantage of mp4 and the FMS server while we use it for overflow as a recorder.
Can anyone clarify if this can be done?
Thanks
-Brian

Recording can be triggered via client-side publish call, or via server-side script. From the publish cmd, you specify "record" option. For example,
ns.publish("mp4:foo", "record"); // ns is a NetStream, "mp4:" prefix tells FMS to record using MP4 container
Otherwise, if you want to trigger the record via server-side as Jay says, you can simply publish the stream as,
ns.publish("mp4:foo");
then from server-side AS, do something like,
// this handler is called when a stream is published
// clientObj is the client that is publishing the stream
// streamObj is the stream that is being published
application.onPublish = function(clientObj, streamObj)
streamObj.record("record"); // start recording the stream

Configure Live streaming FLV Encodering -- Adobe -- End user

Hello,
WHile looking on the web, there are no clear cut instructions on how to configure adobe media server fro live streaming.
What I would like to do is take a streaming coming from alive flv streaming source. Have adobe media server configured to allow users to connect to the media manager and watch the live stream.
Could someone provide directions on this?
Thank you,

How do I create a variable video delay of a live stream...

I have a live video feed from my webcam in my Flash Application. I have a second video window next to it that I want to place a variable delayed video of the live stream. Therefore, I need to save the video stream in memory/disk and create this variable delay, say 5-60 seconds. As well as, continue to capture the live stream. The camera I am using suppots H.264 encoding.
How do I create a variable length queue or buffer to hold the video stream coming into the flash application. Do I create a memory variable or write this to disk ? I have been looking over the ActionScript 3.0 documentation and I can not figure out how to code this either way ( as a memory variable or write to disk queue ).
I want to be able to change the delay, view the delay stream in slow motion and scrub through the delayed stream.
I would like to do this with out having to use Flash Media Server.
Thanks,
Bob

I am sure it is practically impossible to accomplish that on the client side. Although theoretically it is conceivable to use NetStream.appendBytes() but it requires an extremely complex implementation.
I suggest you look into FMS DVR capacities:

Live stream not live- plays like VOD

Hi All,
I'm not sure if this belongs in the AS3 forum or the streaming forum, but here it is.
I wrote a pair CS3/AS3 players to send and receive a live video stream (webcam) from a browser. The first is called broadcaster. It makes a NetConnection to my server, publishes a stream and attaches the camera and microphone. This works fine. The stream is live.
The second is originally called receiver. Using an instance of flash.media.video on the stage it also makes a NetConnectin, attaches a stream and calls play. This also works, BUT the receiver stream is not live. It starts playing at time=0 like a VOD.
--- broadcaster.swf ---
var connection:NetConnection = new NetConnection()
connection.connect(connect_url); // my server/application/instance
var stream = new NetStream(connection);
stream.publish("mass", "live"); // live means stream live without recording on the server
stream.attachCamera(Camera.getCamera());
stream.attachAudio( Microphone.getMicrophone() );
--- receiver.swf---
connection.connect(connect_url);
var stream = new NetStream(connection);
video1.attachNetStream(stream); // video1 is on the stage (flash.media.video not FLVPlayback)
stream.play("mass", -1, -1, true); // -1 means play live stream only, -1 means start at 'wherever the live stream is'
How can the receiver not obey the -1, -1 parameters especially if the broadcaster is not recording on the server. How can i see the beginning of the stream!
I believe I read that the flash plugin 9.0+ uses the on2 codec, and I also saw some discussion about on2 not able to stream live -- or not live from the browser plugin, only the flash media encoder.
Can anybody tell me what is going on?
Thanks
Ted

I tried streaming with the Adobe Flash Media Live Encoder3 instead of my Broadcater.swf. This connects fine and pushes h.264 no problem.
But the reciever is still seeng VOD not Live video.
Is there something wrong with my receiver?

Live stream to start with keyframe

Hi,
In a .3gp file, it always start streaming at the first frame (zero seconds in to the stream), so the player always received an I frame first and displays the video correctly from then on.
In a live stream on the Quicktime server it start streaming at current frame (eg. 13 seconds after the encoder has started), so the server sends 5 P frames to the client first then an I frame. The client would display a distorted image for 5 seconds until an I frame was received.
Is there any setting on the QuickTime server to always send I frames (key frames) first for a live stream?
QuickTime Streaming Server Software Version: 5.5.4 Mac OS X (10.0.x)

Big thanks for your reply
Really helped me on my long understanding way to upgrade my live chat application to
work with IOS devices.
So lets continue... make this important post to be a good helper for all developers on their way to stream to IOS devices.
If you can I clarify this - Nitin Goel says:
"Remember, that you need to publish video as H264 codec and audio as AAC/HEAAC for it to work with ios player.. Flash player may not yet support this combination.."
It is not possible for me to use Flash Media Live Encoder.
In this article:
http://sonnati.wordpress.com/2011/05/14/a-dream-comes-true-h-264-encoding-into-flash-playe r-11/
it says:
"A dream comes true: H.264 encoding into Flash Player 11"
and its done by this actionscript 3 code:
var h264Settings:H264VideoStreamSettings = new H264VideoStreamSettings();
h264Settings.setProfileLevel(H264Profile.BASELINE, H264Level.LEVEL_2);
stream.videoStreamSettings = h264Settings;
which will be connected to the NetStream like this i guess:
var h264Settings:H264VideoStreamSettings = new H264VideoStreamSettings();
h264Settings.setProfileLevel(H264Profile.BASELINE, H264Level.LEVEL_2);
nc = new NetConnection();
nc.connect("rtmp://example.com/livepkgr");
ns = new NetStream(nc);
ns.videoStreamSettings = h264Settings;
ns.publish("livestream?adbe-live-event=liveevent");
Is this what need to be done in order to publish video as H264 from webcam and Flash Player 11 in user browser?
And what about publish audio as AAC/HEAAC?
Another important thing:
I am writing my actionscript 3 code in my flash CS4 and publish it to swf.
With this code obviously it give me error...
do i need to upgrade to CS5 or CS5.5 and then i will be able to publish with this code?
again big thanks for any help
