Java :: Red5 - Streaming Dynamic Content To Client
Feb 20, 2011
I'm getting to work with with red5 and am trying to make a basic app that will stream a random video to the client. Let's say I have 3 flvs on my server, I'd like a client to connect to my red5 app and have 1 of these 3 videos streamed to them. The only streaming i've been able to figure out so far uses netStream.play("video.flv"), this doesn't work for me, I want the server to decide on the file to stream rather than the client.

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:
play_btn.play_symbol_txt.background = false;
stop();
isPaused = true;[code]............

I'm working on a Flash project and someone recommended Red5 as a media streaming server. Do I need to know java to use build applications that use Red5 as their server?

I installed red5 successfully, but when I try to connect to red5 to stream a video, the connection fails. If I use netstreaming(null), it works, but when I use red5, it doesn't.

I have several flash clients that send live audio stream to the Red5 server. Is it possible to combine all this audio streams together so that other clients could subscribe only to one audio stream and listen live audio from all publishers?

Is it possible to capture/encode a video file on a slow machine, then upload it live to a Red5 or Adobe Streaming server, and have that server stream to file live to flash clients? If so, what protocol is used to stream the data from the encoding machine to the Red5 / Adobe server? I see a lot of things about RTMP, but am I correct that this protocol is used between Streaming Server and Flash client, but not from encoding machine to Streaming Server?

I am writing a Red5 application that provides 1-on-1 video chat to a Flash client over RTMP.
Unfortunately most tutorials I was able to find were sketchy at best and the documentation of Red5 itself tends to be vague when it comes to API concepts and intended usage.
In short, I am a bit stuck and looking for hints on Red5 ApplicationAdapter implementation. Gnarly details are as follows:
First of all, the connections come in two flavors: visitors and consultants. A visitor should be able to indicate which consultant it wishes to communicate with. A consultant simply gets connected to the requesting visitor as long as the consultant is not busy servicing another. Obviously, every RTMP connection has two-way traffic: both sending and receiving video. From the standpoint of the server, connections bring in a bunch of video streams that get their receiving endpoints assigned by request. Since several video conversations can be in progress simultaneously, the main task of the application is to handle the mapping of visitor streams to consultants and provide a list indicating each consultant's state (busy/available) via AMF.
So, all in all, I have a pretty good idea what I am aiming for but how to achieve it with Red5 is still a bit of a mystery.
What is the easiest way to establish the connection type (visitor/consultant)? Which API classes should be used to implement a persistent, globally accessible list of active connections for reporting the state of each consultant? How to switch receving endpoints dynamically when the goal is to connect a specific visitor to the selected consultant?

I've just finished putting together a basic flash video chat client that publishes the camera to a stream and receives a similar stream from another client.The streams are being pub/sub'd to the "oflaDemo" that ships with Red5.This seems to work fine for my prototype, but I'm concerned about having to use something with "demo" in the name if I were to roll this chat application into production. It seems that the alternative is to essentially re-write that demo, perhaps with a few more features, which doesn't seem right in order to take advantage of one of Red5's core functionalities.
So, my question is: what is standard/best practice for production live streams in Red5? Is the oflaDemo used? Do custom stream brokers have to be written? If I don't host it myself, do most hosts have their own (production-quality) version of oflaDemo?

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 just met a piece of error log when I was trying to resume the paused mp4 streaming. Here is the log from the server:
[INFO] [NioProcessor-1]
org.red5.io.mp4.impl.MP4Reader - Frame
position was not found for timestamp:
92000
I'm using Red5 newest 0.9.1 final for mac os x to stream the H.264/AAC encoded MP4 file to my flash app.
And there's no problem when I'm resuming the .flv file.

Since I'm developing a multiplayer card game for Facebook using Flex as client side and Java SE as server side, I wanted to know how do I actually make the connection between Flex and Java? the server and client should be able to send each other data(cards,movement,room information etc...) across and I wonder what's the easiest way to do it without complicating it. where to read about it ? I know JAVA but I find JavaEE hard to understand.

What technology are better (robust, stable, speed) for rich web app with flash movies, chat, etc. Somebody said that Red5 will drop down if more that 50 users try to suck video stream from it. Is there people who use Java on server side and Flash for client side?

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()) {

I'm building a Flash-based Facebook game with a Java backend, and I'm planning to use a RESTful approach to connect the two of them (not a persistent socket connection). I'm using the AS3 library to connect the client to Facebook, so that's where I have my session information stored. However, how do I authorize client connections back to the server? I can't leave the callback URLs open since that'd let people manipulate game state without playing the game. I need to make sure that the calls are coming from a valid client and through a valid session.
At the moment, users have no direct login to the backend server -- it's all handled through the client frontend. Can I pass the Facebook OAuth2 access token to the backend in a way that the backend can verify its validity? Should that be enough to trust a valid frontend connection?
I could do a two legged OAuth signed request or just use a simple shared secret, but the keys would have to be packed in with the flash client, which makes that almost useless for this use case.

I want to be able to reuse my existing controller logic regardless of whether a request has been sent from a Flex client (using BlazeDS + Spring at the backend), or as a simple HTTP POST/GET request. For simple cases, things work OK, however, there are some occasions when I need to access some session attributes. At first, I almost exclusively used the FlexContext class, but then I realized that when one sends an HTTP request, then the Flex Context is obviously undefined.
My question is, what is the best approach to abstract the session extraction logic,regardless of the type of the request. In other words, I would make a class called SessionManager, which has a method getSession. This class will make a check whether there is a Flex context, if there is, it will return the session of that context. If not, it will simply return the current HTTP session (which I assume is the same as the Flex client session, but I was not sure)

The question is about the following operation: Flash client sends TeX code (or file) to server. TeX is compiled into picture. Picture is sent back to client As far as I can see the best way to do that is to use flash+java remoting. But, there're several java servers (looks like BlazeDS and Red5 are the most popular). Which one do you advise to use for my purposes? Note that steps 1-3 are not final, picture will be changed after that (e.g. some marks will be made).

We're using :
JBoss 5
Flex SDK 3.5
BlazeDS 3, with integrated authentication (through JAAS and JBossSX)
Failed login are always indicated to the flex client by the same fault code : Client.Authentication
However, the underlying JAAS LoginModule throws a specific javax.security.auth.login.LoginException subclass.
How can we propagate the failed login reason to the flex client ?

I'm trying to create a client-side web app that generates music procedurally using some user-input parameters, so I'm looking for a framework (e.g. Flash, Silverlight etc.) that has the capability to play audio at a specified pitch. Whether it is playing a WAV/MP3 file, using MIDI output, or just playing beeps doesn't really matter -- I just need something that will enable me to generate arbitrary music client-side.
I've done a bit of searching and it appears that Flash might have the ability to change pitch with the help of a third-part plugin, but I couldn't find anything similar for Silverlight.

I have Flex/AIR app that connects to a tomcat server via BlazeDS. I'm not finding that I have to integrate an old webapp (struts/jsp) and I'd like to keep that webapp untouched except for login, authentication and session handling. Also a 3rd java app that uses httpclient.
Currently I have some blazeDS remote objects to handle login/logout with a few RPC calls. In turn, FlexSession objects are created and handled. Is there a way to use httpclient and javascript to call those blazeds RPCs so I dont have to recode and have 3 different means to handle logins and sessions?
