Flash Media Server VOD hardware requirements per client

Hi I was wondering what the hardware requirements are for VOD
use of FMS 3 per client.
What I want to do is to be able to calculate what kind of
machines would be required to cater an x amount of clients at the
same time. For example CPU usage per user for a 500 Kbps video is
40 MHz, memory 100MB etc. or if there is a formula. If I have that
then I can also calculate the cost per view etc.
If you have a server with a Gbps connection to a network you
could cater for 2000 users but then if the memory usage is 100MB
per user that would not be possible etc.
Any kind of relative information (even server suggestions)
would be greatly appreciated.
Thanks!

FLEX 2.0 and Flash Media Server 2.0 Unable to stream from client to server

Hi All,
I have been trying to put together a quick demo to stream
and record audio from Client to Server. I get this error when
trying to connect to FMS.
ArgumentError: Error #2126: NetConnection object must be
connected.

my Program fails at this line - ns = new NetStream(nc);
Your help is greatly appreciated. Here is the MXML file

This file contains a simple start and stop button start and
stop audio processing.
This page is served from Apache Tomcat on host : demoserver1
and port 8080
Flash media server is also installed on the same host
demoserver1.
I did not do any additional config at FMS except creating an
application called "DemoApp". All other settings are defaults.

Hi,
Are you trying to make an air app or a web application (flash) for streaming? You may want to check out the osmf framework to help you write a player for mobile platform. Check out http://www.opensourcemediaframework.com/ for more info on how you can write streaming video players using this framework. There are some good tutorials there and also you may post on the forum to get your specific queries solved.
Thanks,

Flash Media Server for iPhone

Hi,
I am developing an app for iPhone/iPad. The client wants to show some realtime data in the app. Something like a chat application, where even if users don't do anything (flash uses no event), they can see what other users are doing in realtime.
I went through adobe site to see Flash media Server for mobile device. But I am confused on which version of the server should suit the type of app I am developing.
Thanks,
Salim

I'm more or less in the same boat. I've got the admin console
up. I am able to run the vodtest application locally pointing the
video file to rtmp://localhost/vod/sample.flv or using the server
name instead of localhost as in rtmp://mclmedia/vod/sample.flv
I can also load the html and swf file to my xp machine that
has access to the server via our internal network. (DNS isn't
configured yet) But the connectionFailed message appears when I try
to call the videos using rtmp://mclmedia/vod/sample.flv

Questions before I buy Flash Media Server 2

Hi! I'm considering buying Macromedia Flash Media Server 2.
This software would be a large investment for me, so I'd really
appreciate any answers or advice that anyone could provide. I just
have a couple questions:
1) Can FMS2 be installed on the same server that runs my Web
sites? I have a Linux server that runs a few sites, and it would be
ideal to run this software and the sites on the same server. I'm
also wondering what port it would run on? I've used RealNetworks'
Helix Server, which requires you to run it on a separate server
because of port issues. I want to use Flash instead.
2) Does this software also come with a Flash video player
that would work with my sites? I want to be able to stream .flv
videos from my Web sites and have a Flash player launch whenever a
user selects one of my videos (kind of like how RealPlayer launches
when you click a RM file). This way, the player wouldn't always be
embedded in the page. Is that possible? I'm worried about the
player failing to launch, or people needing to download a special
player to view my videos.
Thanks very much!

1) Yes you can run it on the same box as your web server. You
can specify any port you wish for FMS to listen on (default is
1935)
2) I'm not quite sure I understand. In order to view your
videos a client will have to have a flash browser plugin installed
- which should not be a problem as flash browser penetration is
somewhere in the high 90th percentile (if Adobe is to believed). In
addition, your flash application will need to make a connection to
FMS before it can stream videos, so its not quite as simple as
clicking on a .flv link. Your flash app will have to be embedded in
a page (think youtube - although youtube does not use FMS).
If you're not sure if FMS is right for you (and you sound
like you're not sure), why don't you download the Developer edition
and test it out? Its free and has all the features of the "full"
version, but only gives you a license for 10 users.

Playing mp3 over RTMP (Flash Media Server)

I've got some mp3 files that are served from a Flash Media Server. I want to write a Flex application to play them. Do I need to use NetConnection/NetStream or can I do it with just the Sound class? I've got a sample app that can connect to the stream with NetConnection/NetStream but I don't know how to connect the netstream data to something that will actually play the sound.
Will I be able to read the id3 data of the files with this?

Flash Media Server on Clustered Servers

Hello to all,
i am new to the Flash world and am trying to figure out if
Flash Media Server Pro can be installed in a clustered server
environment (active/passive). specifically:
1 - can it be set up so that when the primary server fails,
the secondary server will take over any incoming requests?
2 - can this be done at the "Pro" license level?
3 - are two seperate licenses required for this, or is this
usage (since it is any active/passive cluster) covered under a
single license?
the items i found on the site are very specific to setting up
Edge/Origin servers - but we are not looking at getting dedicated
servers for this. we want to use our clustered web site servers.
with thanks for any help provided
rica

Since we're talking about a multiuser app (the chat),
failover becomes a litte more complicated. In this case, we need to
make sure that, as clients connect to the app, the are routed to
the appropraite server. Think about this scenario:
Users A and B enter a chat. During the chat, the primary
server goes down, so clients A and B are moved to the backup
server. A few minutes later, the primary server comes back on line.
After that, client C connects to the chat. Since the primary server
is up, client C connects to that one, but clients A and B are still
on the backup server.
So, we need a means of making sure there is only one instance
of any given chat "room" at any time, and we need to somehow make
sure inbound clients are routed to the appropraite server.
What I like to do in situations like this is buid two
applications. The first application is a "gatekeeper", which
monitors all of the FMS servers in the cluster, and mantiains a
list of active rooms (and their locations). When a client connects,
they first connect to the gatekeeper, which informs the client of
which server their chat room is running on. The client then
disconnects from the gatekeeper, and connects to the chat room.
Along with handling faliover, using an approach like this can
also facilitate load balancing. By monitoring license capacity, the
gatekeeper app can programatically assign chat rooms to servers
based on the number of active connections on each FMS.

Re: Flash Media Server 3.0.1

Dear all:
Sorry I am new to Flash Media Server.
I have Flash Streaming Media Server 3.0.1 installed on our
Windows Server 2003.
I cannot access to the my video files from the server's web
browser. And also from the client's PC. How can I do that.
Any urgent help will be highly appreciated.
With best regards,

Der sir,
Thanks a lot for your reply.
I followed the pdf. I could connect from the server to its
vod files (rtmp://localhost/vod/sample.flv).
But how can I connect from a PC?
Should I download some client software?
Thanks for your kind help.

Record playback is very slow between Flash Media Server and Flash

hi all
I have done server side recording successfully with red5 flash media server and can see
that the flv record is being created properly.
Then if I try to playback the record like
NetStream.play("record.flv"), I see that stream playing is very very
slow, for both of audio and video.
And then if I try to playback the recorded file via using the
filesystem path of it, everthing seems fine.
Problem occurs when I try to sucscribe and play the stream of the record.
PS : There is no problem with playing the published stream
(NetStream.play("streamName"))
Does anyone have an idea about this issue?
If you need any additional information, please let me know.
Thanks in advance
Regards

In a nutshell flowplayer delivers the video through your web
browser. It does this via http protocol (port 80) and progressive
download on any web server
Progressive download finds the video on the server and plays
it back through the player as it is being downloaded. 2 important
things to take from this are 1, the video is being downloaded to
the clients hard drive, at the end of the playback they will have a
copy of your video that they can do whatever they like to and
repost it somewhere else. 2, It plays back as it downloads, meaning
if I'm viewing a 10 minute video from your site and want to skip
ahead to the middle or end I have to wait for the whole video to
download before viewing those segments. Your web host by the way
will love you for progressive download because it will appear as
though your transfer rate has gone through the roof. Once the
request for the video is made there is no turning back, the client
gets the whole thing whether they watch it or not.
Flash media server uses the rtmp protocol. This protocol is
an open socket protocol through port 1935. This is a two way street
essentially. When the user views a video using FMS they basically
get only enough of the video to keep the connection open and
satisfy the required buffer to assure clean playback. The bytes of
info that carry the video only go to the users memory, not the hard
drive. This allows the user to jump back and forth around in the
movie without having to wait for the whole thing to download.
Hope that helps.

Flash Media Server Bandwidth Limitations

Is there anyway to utilise the bandwidth of the flash media server from the server side in such a way so that the streaming will happen from the flash media server to the user based on the user internet connection speed. So users with low bandwidth will receive less streaming data in their buffer and users with high bandwidth will receive more streaming data into their buffer from the server.

Perhaps i didnt get your qeustion properly. users at lower bandwidth are forced to receive less data per second compared to the users who are at higher bandwidth who will be receiving more data. Do you want to perform dynamic streaming, where in you setup same stream in multiple bitrate and then choose to stream to the clients based on their bandwidth conditions? Like low bandwidth user will receive lower bitrate stream and high bandwidth user will receive higher bit rate stream.
Let me know if this is not what you are talking about.

Very basic question: Flash Media Server vs. embedding flash video

I'm hoping this is a quick easy question to answer:
What is the difference between Flash Media Server and simply
using a freeware Flash media player (like Flowplayer
http://flowplayer.org/) that
uses XML playlists to embed your Flash videos on a website?
What are the advantages to Flash Media Server and how does
something like Flowplayer not address issues that FMS can?
Thanks in advance!

Is Flash Media server being used commercially--TV? etc.

Would much appreciate some concrete (live time) examples of Flash Media server being used in a commercial enterprise. Prefer domestic (US) but any will be great. Any closed network systems such as a multi-campus university?
Is it being used only as a one-to-many distriution tool? Or, is it being used as a many-to-many remote classroom environment?
Thanks,

On your requirement of having your web app manage access, your developers will need to program some supporting classes on the FMS side. If the web app is to maintain access control, the flow will work like this:
1. User credentials will be provided to the client side application (the .swf) either by manual entry via a form, or by runtime variables provided in the flash object embed code.
2. When the client connects to the FMS application, the credentials will be passed in the connection request
3. The FMS application will make an HTTP request of the web application server to validate the credentials.
4. The web app server will reply with a pass/fail result
5. The FMS application will accept/reject the connection accordingly.
Server side programming for FMIS (server side actionscript) is Javascript, so if your developers are already experienced with Javascript, they should have no problem getting comfortable with the FMS API.

Is Flash Media Server the software I need?

Hello!
A client needs a Flash streaming software to best serve the following:
750 Mb/s Internet bandwidth
Average 7 minutes video length
Average 1,100 video requests
3,500 video requests at peak hours
99,9% SLA
Will Flash Media Server do the job or will I need something else?
Thank you very much for any ideas.

> 750 Mb/s Internet bandwidth
Sure, FMS can handle 750Mbps of throughput
> Average 7 minutes video length
Not an issue. It doesn't matter how long the videos are (although on a 32 bit OS, the file size has a limit of 2GB)
Average 1,100 video requests
Assuming the server has adequate hardware and network resources, 1100 concurrent streams is realistic.
>3,500 video requests at peak hours
A single FMS won't handle that many concurrent streams. You'd need to distribute the load across at least two servers for that capacity.
>99,9% SLA
There is no SLA associated with the software. That's something your hosting provider would be responsible for, and it wouldn't apply to FMS... just to the server FMS is running on.

Why Flash Media Server

Hi All,
As it stands currently, I'm developing online teaching applications that faculty can use in their classes, as well as encoding and uploading videos to our Windows Servers. For database management, I'm coding server side scripts in PHP, and dumping everything into MySQL. Then embedding all the content into Moodle (which is hosted by a 3rd party).
I'm looking at a Flash Server Solution for a couple of reasons:
1) Delivering Streaming video instead of Progressive Download
2) Allowing instructors to encode and upload their own videos (similar to YouTube) without having to go through my office
3) Providing extra copyright security - in order to use some copyright videos, we have to ensure that only the students who are enrolled in specific classes can access the data. As it stands now, a smart student with the right URL can download anything we have up on our Windows servers.
Some Questions and concerns:
1) I don't know Cold Fusion. Will I have to rewrite all my scripts for that? Can Flash Media Server run PHP?
2) This is probably a really stupid one, but... Is Flash Server it's own platform, or does it have to run on a Windows or Linux box?
3) Does it need its own dedicated machine? Can you run a virtual server with Flash Server?
4) Which of the different flavors of Flash Server are best?
5) What kind of hardware specs are we looking at? We have 20,000 students and maybe a few thousand at any one time would have to access
Sorry about all the dumb questions. I'm mostly an app developer, but am in the position of having to make this decision, and then defend the decision if I decide to puruse a Flash server solution.
Thanks for your help.

Hi riquigley,
Following are quick answers on a few of your questions. Hopefully other folks will add their thoughts and also answer the questions I have skipped over.
4) Which of the different flavors of Flash Server are best?
-- FOR STRAIGHT VIDEO STREAMING USE Flash Media Streaming Server. THE PRICE POINT IS LOWER THAN Flash Media Interactive Server (aka FMIS. FMIS IS ONLY NEEDED FOR INTERACTIVE APPLICATIONS, E.G. MULTIUSER, CHAT, ETC.)
-- COMPARE EDITIONS PAGE HERE:
http://www.adobe.com/products/flashmediaserver/compare/
2) ... does it have to run on a Windows or Linux box?
-- YES. FMS IS A SERVICE THAT RUNS ON AN OS. WINDOWS AND RED HAT LINUX ARE SUPPORT. FULL REQUIREMENTS HERE:
http://www.adobe.com/products/flashmediastreaming/systemreqs/
3) Does it need its own dedicated machine? Can you run a virtual server with Flash Server?
-- DEDICATED MACHINE *NOT* REQUIRED.
-- HOSTED SOLUTIONS ARE AVAILABLE TOO. HOSTED SOLUTIONS MAY OFFER: A) BETTER QUALITY; B) LOWER TOTAL COST OF OWNERSHIP; C) QUICKER START TO LAUNCH.
-- SEE LIST OF HOSTING PARTNERS, AKA CDNs (Content Delivery Networks) HERE:
http://www.adobe.com/products/flashmediaserver/fvss/
1) I don't know Cold Fusion. Will I have to rewrite all my scripts for that? Can Flash Media Server run PHP?
-- COLDFUSION NOT REQUIRED. EITHER PHP OR COLDFUSION CAN BE USED TO MANAGE METADATA (INCLUDING SQL DATABASE INTERACTION).
-- PHP AND COLDFUSION HANDLE ALL HTTP REQUESTS AND RETURN DYNAMICALLY GENERATED PAGES TO THE USERS' BROWSERS.
-- FLASH MEDIA SERVER HANDLES ALL RTMP REQUESTS. DYNAMICALLY GENERATED PAGES FROM PHP WILL INCLUDE THE RTMP URLs THAT THE FLASH/FLEX SWFs USE IN THE BROWSER TO REQUEST THE RTMP STREAMS FROM THE FLASH MEDIA SERVERS.

RTMFP support in Flash Media Server 4

I see that the new Flash Media Servers were released. Looking over the information on the product pages, Flash Media Enterprise Server 4 is the only available product that supports RTMFP connections?
We currently have Flash Media Server 3.5 and our product utilizes RTMP connections, but I've been working with your Stratus Server and RTMFP and have found that the new protocol better fits our needs. However, the price for Flash Media Enterprise Server 4 is beyond our budget. Is there any possibility that RTMFP support are/will be available in the lower levels of Flash Media Server? If not, is there any idea on the time frame for the end of Stratus?
Thank you.

Ed Chan wrote:
No, unicast means the client can make an RTMFP connection to the server, and data can only be sent between client and server. P2P functionality requires FMES.
Forgive me as I'm still wrapping my head around FMS.
So the RTMFP unicast with only 2 machines would basically be the same as RTMP connections to a server running a particular application?
MachineA ----RTMFP--->FMIS==\
|<-> Application1
MachineB-----RTMFP--->FMIS==/
Doing it this way... the machines can still communicate with each other through the application they are connected to on FMIS?
