Media Server :: "NetStream.Play.InsufficientBW" Dispatched When There's Plenty Of Bandwidth?
Mar 29, 2012
I am working on the Audio-Video application having two Flash Media Server, One is Flash Media Interactive Server and another is Flash Media Streaming Server.I am publishing stream on Flash Media Streaming Server and receiving stream from Flash Media Streaming Server. Flash Media Interactive Server publish stream to live folder "rtmp://xxx.xxx.xx.xx/live" Flash Media Streaming Server from server side code.when application.onPublish of Interactive server dispatch then the stream published by interactive server has been republished to live of the streaming server and from there client receive stream by
making connection with live folder of Streaming server. Stream from streaming server received successfully but

We've upgraded our production servers to 3.5.3 on Windows 2008, and now I'm seeing a lot of "NetStream.Play.InsufficientBW" statuses in our client app's log The server is streaming a very low bandwidth live video/audio stream, and the client has more than plenty of bandwidth to play it The stream doesn't exhibit any audio drops or skipped frames, and there are no message drops on the server side We have had clients complaining of random disconnects. Does anyone know why I might be getting this message

I am streaming pre recorded audio files (mp4) to an AIR client. I have tried two different solutions,
streaming the file directly with the NetStream.play("mp4:xxxxx.m4a") and creating a server side playlist, adding the same sound clip and then streaming the playlist. The problem is, when streaming the playlist i get a few NetStream.Play.InsufficientBW, this does not happen when streaming the file direct. Both solutions uses bufferTime=1.0
I would like to use a server side playlist to implement a simple key solution so that the client dont know the full path to the file, but instead sends a key to a custom server side function that looks up the file path and creates a stream for the client.

I got a bunch of live stream from FMLE, say: "FMLE_channel1", "FMLE_channel2", "FMLE_channel3". And then on the server side, I created several corresponding republished stream called "channel1", "channel2", "channel3".
On periodical basis, we call Stream.get("channel1").play("FMLE_channel1", -1, 10, true) every 10 seconds. Similar things were done on the second channel & third channel.Soon after the above Stream.get("channel1").play() call, I should get the following events in sequence:info :NetStream.Unpublish.Successinfo :NetStream.Publish.Startinfo :NetStream.Play.Resetinfo :NetStream.Play.Start In the above case all are happy. Clients can view channel1, channel2, channel3 well.But then after a while, one of the three channels, in most case it would be channel1, will not be viewable.
With the server trace info, I found that after the Stream.get("channel1").play() call, only the following two events exists:
info :NetStream.Unpublish.Successinfo :NetStream.Publish.Starti.e. I was missing the play.reset and play.start event.I further checked and confirmed that the FMLE was publishing all three channels fine to the server. I was able to view the "FMLE_channel1" from flash clients, but not the republished "channel1". the version is FMS 3.5.0.

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.

I'm recording audio using FMIS, the file is being saved out as a FLV file and I am able to play it back. Eventually that file may be deleted after some time and I would like to notify the user if the file is no longer available. I was expecting to see NetStream.Play.StreamNotFound after deleting the file on the server but I'm not getting that message. Instead I get:
--> NetStream.Play.Reset--> NetStream.Play.StartAnd nothing plays which is expected since the file is deleted, but I dont get the right message. I'm calling the file like so:ns.play ("flv:file_to_stream");

I'm streaming mp3 on flash media server 3.5 on linux version, and very often come accross with that problem, when the buffer.length become 0 on client side, the streaming will stop with NetStream.Play.Stop event, and will not be continued. I think this case it should wait always till the data arrives and never should stopping. Some more info : I tested on applications/live folder, and the mp3 files are created dynamically during the playing, and the creation speed is almost the same like the playing speed, so those are not fix files.

I would like to have the possibility to detect when NetStream is not working (i.e. the name used in initialization can't be found on the server side). The StreamNotFound doesn't work at all. I've read that it's the fault of the Flash Media Server, which automaticaly creates new stream, if it cannot be found (of course it's an empty stream - what is wrong from my point of view). Is it true? If yes, can I disable it on the server side, so I could easily detect if the stream name is correct?

NetStream.play(streamName, -1); This seems to be working wrong.if I have recorded an flv on server using FMS and FMLE with only audio with name "myaudio" and then after if I try to play a live stream using NetStream.play("myaudio", -1) then it plays the recorded stream. I believe that documentation says that it should start a live stream instead of playing recorded stream as the second argument is -1. Is this a bug in NetStream.play method?

I am experiencing an issue with playback on RTMPE streams. after investigation it seems that the FMS server is firing the NetStream.Play.Complete message at random points, indicating that a stream has ended. This is happening and random points during the stream, not even close to the end.[code]As you can see roughly 17mins into playback...although the stream is 1 hour 24mins long.I have tested this numerous times, and each time it is at a different point in the stream.Intermittently the NetStream.Play.InsufficientBW warning is being fired prior to NetStream.Play.Stop.I am using a player built on OSMF 1.5

I have a series of mp4 videos (H.236 @ 22 fps) streaming from an akamai FMS serve via RTMP protocol in flash player 9+ with AS 3.My goal is to create client side playlists that smoothly switch from one stream to another. I am creating these playlists using a series of netStream. play (filename,start,len) methods. If I don't use an offset for the start parameter, then the stream switches smoothly from one video to the next with not noticeable jump or jerkiness. However if I introduce a start offset, say a few seconds in, I start to see a quick little hiccup or pause between the seams as it switches from one playlist stream to the next.

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?

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?
