Media Server :: High Bandwidth Is Used By The FMS 4.5 When Serving A VOD File?
Feb 9, 2012
We noticed that when we are streaming our own VOD file that we had copied to the server, which is an .MP4 file encoded at 1200 kbps using either HDS or RTMP (, which I suppose the server recodes on the fly ) we are getting the incoming stream at the average bitrate of 14 Mbit/s, and it looks like bursts of 25 Mbit every couple of seconds.
However if we try a sample file, such us sampl1_1500kbps.f4v we are getting an average of 1.2 Mbit/s with peaks of 1.5-2 Mbit. The tests are conducted in our company LAN. So what is the reason for this? And is there a way to control/restrict the output bandwidth for our own file without re-encoding? I'm not talking about several streams with different bitrate for the same source aka adaptive bitrate but rather about the single stream bw)

We are having a little problem implementing bandwidth detection with FMS, for some reason when enable it, bandwidth consumption spikes significantly I am wondering why? and if there a white paper somewhere that would talk about how properly implement this feature.

When a client connects to an application (nc.connect) this is catched at server side using application.onConnect; so, when the client asks for a stream (ns.play) ... does this have some correspondence at server side ? Can we catch this event in some way?Or, seen from another point of view: is there any way, from within an application, to know what stream(s) the application is serving ? I mean, if we want the list of connected clients we have the application.clients array; is there any correspondence from streams ?

We have installed Flash Media Server on a Linux machine.It has 2GB of RAM,Fedora 9 with kernel 2.6.27.5-41.fc9.i686, the install required a few packages (compat-expat1 was one) to be installed before we saw the sample page. The sample page takes a few minutes to load and opening the page to connect to the admin console is about the same.
This is currently on our internal network while we try and see how it works. Are there any specifc TCP related kernel tuning parameters (eg in sysctl.conf) which need to be put in place over and above the out-of-box configuration. Any troubleshooting hints which might identify the problem. The install seemed ok nothing in /var/log/messages and checking to see what is running (ps aux | grep fms) I see
./fmsmaster -silent/opt/adobe/fms/Apache2.2/bin/httpd -f ./conf/httpd.conf -d /opt/adobe/fms/Apache2.2 -k start/opt/adobe/fms/fmsedge -edgeports :80,1935 -coreports localhost:19350 -conf /opt/adobe/fms/conf/Server.xml -adaptor _defaultRoot_ -name[code]....
but when we clear our browser cache and go to a page it is taking forever.It is taking about 5 minutes to open up the initial page, but when it is open the videos all seem to come through fine.The server previously had apache on it but I removed that copy and went with the version included with FMS.

I need to serve live video streams to Flash players, Apple devices, and Android and Blackberry handhelds. Right now I'm using FMS (actually, the CDN I stream through is running FMS), and configuring Wowza Media Server to suck the Flash stream from FMS and reprocess it for Apple, Android, and Blackberry. It works well, but it's kind oif a PITA having to have a separate server just to handle mobile devices.
Is anyone aware of any plans to release a version of FMS that will stream directly to Apple and Android? I saw a video clip on Techtilt of an Adobe presentation at NAB where they were showing live streaming to iPad, but that clip didn't way anything about when we might actually see that version of FMS become available.

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.

As stated in the title, I want to know how to determine if my server/host has native bandwidth detection. I have FMIS 3.5 installed on my Linux server. Is this a setting in FMIS or is this something I have to call my host to find out?

i am currently playing around with a flash media server trial in combination with the flowplayer.All in all i am testing the performance and general functionality for the company i work for.Anyways, i am trying to search a way to check the bandwidth of a client ( server sided ) and redirecting him to the right video stream.Sure this could be done by the backend flash application, but its out intention to perform this check server sided.

I'm trying to stream a webcam from 1 server to many client, what I really need to know is :1. How to adjust a bitrate video for bandwidth streaming, is it enough just using a Camera.setQuality() ?2. If u set Camera.setMode() at large resolution, for example at 1024x768 is it could make the bandwidth for client access increase too ?I mean is it affect the bandwidth for set the resolution at small (ex: 160x120) or set at large (ex: 1024x768) resolution.3. Same as number 2. just it was for video=new Video(w, h) . Is setting a video size affecting the bandwidth ?

Is it possible to limit globally the bandwidth usage of FMS 3.5 ? I don't want FMS to use all the bandwidth available via our ISP.I want my coworkers and other servers to be able to continue using Internet while sending/receiving data from/to FMS. I know it is possible to limit various bandwidths per Applications, but it seems there is no easy way - using the xml config files - to globally limit the server bandwidth.

I am trying to get the "bwcheck" application to work on FMS 4 on Amazon EC2, in order to detect my upload speed to the server and provide the best quality stream for my upload speed.
The tutorial I follow is this:
[URL]
Both are almost identical. However when I compile the .fla to .swf (having changed the URL for my server and application), and after I load the server-side code, I get the following error in my server-side log:
Method not found (recData)
I understand that apparently it is not finding the method, but I tried getting it off the function in the global scope, tried attaching it to the client, etc. but nothing worked. The original code of the server-side script is:
for ( i = 0; i < 1000; i++ ) {
data += "S->C";
}
Client.prototype.recData = function(data)

rtmfp downloaded from the node, and the upload bandwidth to another node, but the FMS bandwidth limitations Client.getBandwidthLimit () seems to only limit the bandwidth of the server to the client such as RTMP, ask how to limit the bandwidth between nodes, such as RTMFP.

I'm in the process of developing a realtime video chat application where multiple users can send video streams simultanuously. The number of users receiving the streams can be very big, e.g. 10 broadcasters and 500 receivers, each receiver should get all streams.
I use RTMFP connections to an FMS and streams are published in P2P multicast groups by passing the groupspec to the NetStream constructor. Currently I'm having problems with audio/video synchronization and video stream 'jumps' (not continuous). From what I read on other threads, this is related to the fact that there is not enough upstream bandwidth for sending the streams. So my questions are:
How to calculate the required upstream bandwidth on every peer for the given example of 10 broadcasters and 500 receivers (is it 10*bandwidth of one stream)?What settings (on NetStream, Camera, Microphone etc.) should be used for best results and how to adapt them based on the number of broadcasters?

Situation: live hls multi-bitrate, livepkgr, m3u8 served on "my" website
(iOS user gets on "my" page, clicks on the m3u8 link and views the live content - no problem there...)
What is stopping other to use my playlist on their website and offer the same service with "my" infrastructure?
If i use protected hls - i still will be giving keys to all the viewers - both those who came through my website and also all others.

I have confirmed this behavior in FMS 3.0.2 on Windows 2003, Vista, and Linux.
In prior versions of FMS if I had a publisher sending a live video feed to the server, then I could have subscribers connect to the server and set a bandwidth limit for them and the server would ensure that the subscribers only got as much bandwidth as I set for them. As of version 3, the server now ignores this limiting for live streams.
You can set a limit on the publisher which of course then limits the live stream that subscribers view, but that is not what I want. I want to have the publisher push a live stream at the quality I specify and then I need a way to give some subscribers a lower bandwidth version of that stream. This all worked fine in prior versions of FMS and I can't imagine this is intended behavior in version 3, but it seems like a major oversight.
The bug can be replicated by creating a simple flash app to stream live video to the server and then in a separate NetConnection, subscribe to that live stream and display it. Then on the server side, setup an application.onConnect to do a setBandwidthLimit on the subscriber and you can see that it is totally ignored. You get the full bandwidth stream even though the limit should be reduced for the subscriber.

we are using RTMP with Flowplayer with dynamic bitrate switching and I'm a bit confused on the bitrate (kbps) that is called out in the code in order to configure the bandwidth check. I presume that this is the target bitrate if encoding using ABR or constant. How about for the rest of us that are using CRF? My understanding is that CRF is the way to go now for H264 (don't want to hijack the thread to a CRF vs ABR discussion). If we are using CRF, can we guess on the target bitrate that is called out in the bwcheck plugin?

Does anyone know if Flash Media Server can be configured to reduce the image quality of a publish stream if available bandwidth goes down or there are delays in the connection?
When I (locally) play back videos recorded on poorer/intermittent connections, video frames are dropped, so the image freezes up.

I'm trying to determine an initial value for NetStream.bufferTime based on the client's calculated bandwidth and the video's bitrate.As far as I can tell you can't do this, because you must have an initial buffer set BEFORE you call NetStream.play() (or use the default 2 seconds) and FMS does not call NetStream.onMetaData, where one would normally find the videodatarate, until after NetStream.play() is called.Even if you modify NetStream.bufferTime during the onMetaData call back it doesn't effect when the video starts playing or when the NetStatus event registers "NetStatus.Buffer.Full".
How do I find the Video Data Rate BEFORE I call NetStream.play?How do how do I reset the initial bufferTime before acctual play back begins and the NetStatus event fires with "NetStatus.Buffer.Full"

Has anyone been able to get bandwidth detection to work using the flvplayback control (client side - using AS3)? I have successfully got it to work using the video component with bwcheck and bwdone but I need to figure out how to do this with the FLV playback control. I am using FMS 3 and do not want to use the native bandwidth detection that comes with FMS. I need to detect the clients bandwidth and set the buffer time and what bitrate of a video (high, medium, low) I provide to a user based on their bandwidth.
In other words, is there an equivialant of bwcheck and bwdone that the flv playback can hook into to detect the client's bandwith?
