Live Instance in Flash Media Server 4.0 crashes/causes stream failure

Hi,
I have a Flash Media Server streaming version 4.0 server that is expierencing some issues. Currently multiple inlet encoders are publishing live video content to this FMS. At random times, the live_definst_ instance will crash and then restart itself. The encoder does not recognize this new session and as a result, no new live video is being sent unless the encoder is stopped/started. This cannot be done during live events, however.
I also have an enterprise version 4.0 that does not have this issue. Is there a fundamental difference between the streaming/enterprise versions that would cause this issue and if so, is there any modifications that can be done to the streaming server that can fix this?
Also I've noticed on the master logs that the enterprise server has various
_defaultRoot_L_defaultVHost_:::_0 expierenced 1 failure's
After this it seems like it starts. However, the streaming server has this:
_defaultRoot_L_defaultVHost_:::_0 expierenced 2 failure's
Recovering core _defaultRoot_:::: with 2 failure[s] after 300 seconds!
What exactly is this "recovering" process, could this be what is causing this issue? Can I disable this in the config?

You need to place the crossdomain.xml in the webroot folder. Create a text file in the webroot folder using notepad, and call it crossdomain.xml. The text below will give you a wide open access policy, which is fine for testing.
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<allow-access-from domain="*" />
</cross-domain-policy>
For debugging HTTP streaming I recommend you get hold of something like Charles or Fiddler. These will greatly assist in pinpointing any issues.

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,

Streaming live audio without flash media server

I have an mp3 player, that I would like to add live streams to.
here is an example url of what I'd like to stream. http://85.17.174.181:6968
is there a way to do that in flash AS3?

>>don't tell me I need the server to include me in their cross-domain policy???
Always... servers that allow public access will typically have a wildcarded cross domain though. And in that case you just need to tell the sound load to check the policy file using SoundLoaderContext like so:
var context:SoundLoaderContext = new SoundLoaderContext(100, true);
var a:Sound = new Sound();
a.load(new URLRequest("http://85.17.174.181:6968/"), context);
a.play();
It doesn't look they have a crossdomain.xml file in place though...

Can any one tell me when i use adobe flash media encoder how can i see my live vidoes on flash media

Flash Player version 10.1.102.64 is the last version available to PPC Mac users. However, this Flash version won't work for many videos on Facebook, YouTube and other sites. Adobe's latest version, 10.2.x or later, is only for Intel Macs. Adobe will not provide a newer Flash version for PPC Macs.
The message requesting that you download Adobe Flash Player takes you to Flash Player requiring an Intel processor. Doesn't work on a PowerPC processor. I found a hack, installed it & it works with Firefox, TenFourFox & Safari.
Download this http://www.steelbin.com/FPforFBPPC.zip to your desktop, unzip it, and replace the current Flash Player plug-in which is in your main/Library/Internet Plug-Ins folder, (not the user Library). Save the old one just in case this one doesn't work.

Should I choose Flash Media Server?

Hi,
I'm trying to decide if I should purchase flash media server
for my streaming needs. I like working with flash, so that's why
I'm considering the flash media server.
Here is my streaming server "wishlist":
-variable playback speeds(fastforward, skip, rewind, restart,
etc)
-option of downloading entire video to local machine
-support for multiple file types or conversion/encoding
multiple file times
-security options to lock down source files
-a flexible platform to build custom players
-hook up to a database(mysql, mssql)
I looked through the flash media server specs on the Adobe
website, but they really don't get into specifics.
Thanks

Live Streaming video and Flex2(3?) + Flash Media Server?

I've seen alot of topic on how to create video sites for
clips, etc. with Flex and Flash Media Server, but how about live
streaming video, like a concert or a seminar. I can't find any
information on this at all, could anyone point me in the right
direction?

What you need is grab video/sound form camera/mic, publish it
on FMS and let the other clients play it. In a few steps:
// get camera and mic
var cam:Camera = Camera.getCamera(); // get default camera
var mic:Microphone = Microphone.getMicrophone(); // get
default mic
// if you have VideoDisplay, for monitoring
videoDisplay.attachCamera(cam);
// create new RTMP connection to FMS/your app
var nc:NetConnection = new NetConnection();
// new stream should be create *after* nc has connected, not
before
// so this is executed after the below nc.connect() succeeds
nc.attachEventListener(Event.CONNECT, function(){
var ns:NetStream = new NetStream();
ns.attachCamera(cam);
ns.attachMicrophone(mic);
ns.publish("streamname", "live"); // or "record" if you want
to live+rec
// connect to default instance of app 'appname' on your FMS
nc.connect("rtmp://fms.ip.address/appname");
If you're using Flex2 and FMS2 (the latest FMS is 3), you
might need to
cuange the connection encoding to AMF0 (which is what FMS2
uses) in order for this to work.
Hope this helps; I've written it from my head so it probably
has mistakes, but it's the general workflow; the docs in the
language reference for specific functions mentioned here will also
help.

How to use flash media server with cisco show n share live event module?

hello all
Is it possible to use flash media server in show n share (non dme)live event ? i 've configured flash media server, can receive multicast streams, bu i have no idea what to write in video url fild in the live event basic setup.

Hi Temur,
You should be able to stream from a Flash Media Server.
The URL should look like this:
rtmp://xxx.yyy.com//flv:
You can do some tests from a PC to get the exact URL that would suit your environment.

Nicolas

Live Streaming with flash media server

Hi,
i am installing flash media server 5.0. And its working perfect locally, I need to publish my video through my own IP address. How can i configure local to server

Thanks for the response

Beginners guide to integrating Flash Media Server 2?

I'm a newbit to Flasha dn flash media server and need some
help with integrating the two products. We've just purchased Flash
Media Server 2 to stream user created videos to a website. Idealy
we would like to use the FlvPlayBack component placed on the stage
to display the FLV file from the media server, but cannont get the
component to access the FLV file.
Media Server Configuration:
On the Media Server we created an application (testapp) with
an default instance (_definst_). The directory path for the
Appliation looks like this W:\MediaApps\testapp\streams\_definst_\
The name of the server is MediaServer
The application and instance are appearing in the Media
Server Admin manager.
I've placed an FLV file (Movie.flv) In the _devinst_
directory.
Flash FLA file
Placed FLVPlayback component on the stage
Set contentpath= rtmp:\\MediaServer\testapp\_definst_\Movie
Set islive=true
When I test publish the file, the video does not display?
Does anyone have any guidance on what I need to do? There
seems to be a lack of documentation on integrating the media
server. I looked a sample app called "SimplePB" that works, but
does not use the FLVPlayback component.
Any help would be appreciated.
Thank you,
John Wallwork

John,
For an FLV to stream from FMS, it must be placed in the
streams/_definst_ directory...
applications/myApplication/streams/_definst_/myFlv.flv
Then you would type in the rtmp connection information in the
contentPath of the FLVPlayback component like this
rtmp://myRTMPConnectionInfo/myApplication/myFlv
without the flv extension.
The documentation comes from the FMS components when you
install them.
Here it is...
To set up your FCS for streaming FLV files:
Create a folder in your FCS application folder, and give it a
name such as my_application.
Copy the main.asc file into the my_application folder.
Create a folder named streams in the my_application folder.
Create a folder named _definst_ inside the streams folder.
Place your FLV files in the _definst_ folder.
To access your FLV files on the Flash Communication Server,
use a URL such as rtmp://my_servername/my_application/stream.flv.
For more information on administering the Flash Communication
Server, including how to set up a live stream, see the FCS
documentation at
www.macromedia.com/support/documentation/en/flashcom/. When playing
a live stream with FCS, you need to set the FLVPlayback property
isLive to true. For more information, see FLVPlayback.isLive.

Bill

Flash Media Server 2 - Trace

I have ...
* Flash MX Professional 2004 7.2
* Flash Media Server 2
* Flash Remoting Components
The problem I am having is I cannot get trace messages on
server side scripts to display anywhere. I have looked at View
Applications > {APP} > Live Log, but nothing is there. I have
#include "NetDebug.as" in my code, but while giving no errors, it
appears not to do anything. I really have no idea what is going on,
as I have previously managed to get trace messages displayed
successfully.
Please help and my thanks!

About the security warning... you get that with all .swf's
run locally. To get rid of it, follow the link to add the location
in the security manager. The link will take you to a page on the
adobe site. Just add the path to the .swf, and you won't get that
warning anymore.
About connecting from a local .swf... it will work just fine.
It's the flash client that makes the connection, so it doesn't
matter where it's served or run from.
In your main.asc, the code looks good but you don't need to
load the component libraries unless you're using components
(Communication components, not UI components). Loading them doesn't
harm the operation of the application, it just uses memory where
you not might need to.
In your client side AS, try changing the rtmp string to match
the following:
myNetConnection.connect("rtmp://129.186.168.116/LawnChairLarry");
Note the addition of a second slash after the rtmp, and the
absence of the _definst_ instance name. If you want to use the
default instance, you don't need to identify it.
Next, you'll want to make sure the path to your video file
looks like this:
FMS Install
Dir/applications/LawnChairLarry/streams/_definst_/LawnChairLarry.flv

Audio not streaming correctly from Flash Media Server

Our company has a Flex application (3.0.2) that is having a problem with audio dropping out in Windows 7. The problem appears worse with a wireless connection, but it can’t be consistently reproduced there, either. The only thing known for sure is that the problem has not been seen on any other version of Windows.
The application thinks the audio is playing, because it is calling the appropriate event listeners triggered when the audio completes and when any audio cue points are hit. The majority of our audio is streaming via Flash Media Server (3,0,2,201), but the problem was also seen using embedded sound effects. In one instance, several clicks of a button triggered an error saying the sound effect could not be loaded, and then about a minute later, all the sound effects played at once and the user could then continue with the application.
The problem has been repeated in IE 8, Firefox 3 and Chrome.

Thanks for your details. But i need more info.
Server:
FMS      3.0.2 ?
FMS installed in which platform Linux/windows? more details about it.
Client:
IE          7
Flash Player version     ?
WIndows 7
Wireless connection - Was the client placed in poor bandwidth.
Can you get the NetStream status info when u play the audio file.? We can check for the rebuffering happening at the client side.
Can you run your audio file through flvCheck Tool to check if the media file is in good form. It is available at "\$Root|Flash Media Server\tools\flvcheck.exe"
Now our intention should be to check the same media file with simpler application (since your production app is complicated) to ensure that the media streaming over 'client to server' is working fine.

Recording sound without Flash Media Server?

Hello,
I am totally new to Flash Media Server I need to be able to record sound via a Flash app and save it to a server preferably without the use of a Flash Media Server type setup. There is no requirement for live streaming.
Is it possible to record the sound and save in memory then pass the data/file as a query parameter to the server?
I don't even know if I've posted this in the correct place... any help/guidance will be appreciated.
Thanks.

Hi,
You can use any publisher to publish like FMLE and publish the streams to the application in applications folder suppose application name is sampleApp then create a folder in applications folder of FMS root directory and then keep the below mains.asc file which does the recording of published streams to the sampleApp application.
//main.asc
application.onConnect=function(clientObj)
return true;
application.onPublish = function(clientObj,streamObj){
trace("in application publish");
streamObj.record("record");
application.onUnpublish = function(clientObj,streamObj){
trace("on unpublish");
streamObj.record(false);
I think this should solve your problem.
Regards,
Amit

How can I put video stream on flash media server on to website running on IIS7?

We are encoding live video feed using Flash Live Media Encoder and publishing it using Flash Media Server. Is there any documentation on how I can put this publishing point on a website running on IIS7?

Sorry - but not very clear what you are trying to achieve here - can you please elaborate what you want to do?

Do I need Flash Media Server?

Hi all,
Sorry for this question, but I'm a bit confused. Is there a
way to broadcast live flash video using just flash, or do I NEED
Flash Media server. I don't really have the budget for it, and
don't really know another option if Flash doesn't work.
Thanks

You need a streaming server to do it. FMS is (IMO) the best
choice, but there are two others I know of
Red5 (
http://osflash.org/red5) . Red5
is an open source, free (as in beer), java based flash media
server. It's still in beta, but I hear it's shaping up to be a
pretty solid server.
Wowza Media Server (
http://www.wowzamedia.com)
also has a java based flash server in beta, and the beta program is
open to the public. The projected prices (on their site) put the
price at about half that of FMS.
Just curious, how many people do you need to serve at once?
If it's 10 or less, you can use the free FMS developer
license.
