Media Server :: 3.5.0 Stops Streaming Live Pre-recorded Streams Unexpectedly
Mar 1, 2010
When broadcasting pre-recorded streams on a live applicationFMS always stops streaming at a certain time...
It can be after 10 seconds, it can be after 2 hours, or it can be after any other time, the frame just freezes on the client and the buffer drops to 0.
any attempt to diconnect / reconnect does not resume the streaming, althought the FMS console registers the connected client, no streaming is ensuing. One of the common events we get on the client in such instances when the streaming stops results in get "NetStream.Play.InsufficientBW".[code]...
I am having troubles finding a way to switch videos during a live stream. For example, broadcasting a show and switching to a commercial and then back to the live feed.
I have a problem with recorded stream: The MetaData its partialy correct.Most of the informations are correct, but the 2 most important information for me width and height for the video are always 320 x 240 for any recorded stream althow they are published at different WxH.I tried to get my head around this but cant seem to figure out were the problem is.FMLE its used to publish the stream useing H.264 / MP3 codecs.Here is the server side code used to record the stream:[code]....
I am trying to record a video chat being done through FMS. I have made my program start recording only when the second stream publishes. Then, I stop recording when either streams stops publishing. In my last test I recorded a 45 minute chat. The resulting flv files show that there are 13 seconds difference between them. The video gets more out of sync as it goes along. My first guess is that it is something to do with dropped frames. Is there any way to force FMS to fill in dropped frames. I'm posting my code for starting and stopping recording:
I'm using the server Stream.play() method to playback a recorded stream, it plays back fine until it hits the buffer limit (Say I set the buffer to 5 seconds, it will playback fine for 5 seconds). But then it freezes and playback is very stuttery (1 frame every 2/3 seconds). Is this a know issue? I'm using windows 2008 server. I've tried a few things to resolve this but no luck. The server is running the dev license and has no load.
We have 2 FMS 4.5 servers, one working as origin one as edge we are running our custom DVR application on Origin server, wich records streams. Clients are connecting to edge server and they can watch live or rewind back and watch recorded stream, the problem is after too many clients are connecting to edge server the rewind option becomes unstable, form our investigation we determined that rewind working bad only on that parts of file wich is not cached on edge server yet (caching is working fine when there are not too much clients).
We have currently upgraded from FLV Streams to H264, FLV was much stable and was able to handle much more connections.
What is best way to set up my application. I currently have a working app but the work flow doesn't feel right at all. Here are the basic steps involved:
I use FMLE 3 streaming and recording (DVR) to FMS 3.5, and the sample DVR scripts on FMS for recording the live stream, but the recorded stream not playable (from the remote FMS with FLVPlayback and from my local Developer FMS with Adobe Video Player too). The recorded file is crashed.
There are some recorded flv files. The guy in the video is showing numbers with his hands. (1.flv, 2.flv, 3.flv etc) And there are live idle videos. In these idle videos the guy doesnt do anything.
I need to be able to click 1 as the operator and viewers should see the guy make "1" in the video. Actually I have accomplished so far. It works. I do this:
If the operator selects a video it adds the video to playlist: stream.play(filename, -2, -1, false);
Also have this event handler to play a random idle video when there are no more action videos lined up:
function onStreamStatus(obj) { if (obj.code != "NetStream.Play.Stop") return; switch (obj.code) {
[Code].....
So it is working so far. Problem is:
As time goes by there appears to be a delay between I issue the play command on the stream and I actually see it in the video on client side.
I've been using FMS for a few weeks, and feel relatively comfortable with it, but am currently having some trouble connecting to a live stream in a a video conferencing-type application. I suspect I'm leaving some small step out, but am having trouble seeing what that step is.
I have one client application open the video camera, connect to the FMS, and publish it's live camera stream to the server. Something like this:
I am publishing 2 live streams from a computer with 2 video capture cards in it and I get a lag every 30 seconds or so on the subscribers side. I have tried adjusting the camera quality and setMode properties but still the lag persists inside and outside the LAN, is there a way to create a buffer on the server or adjust the way the live stream is received on the subscribers side so there is no noticeable lag? I saw something about editing application.xml to adjust the queue and a suggested bitrate but not sure if this is applicable, here is the link:

Here is my setup:
The publishing computer:
2 PCI-e x1 cards, one takes S-Video (480i) and the other DVI (720p) Windows 7 64bit Intel i7 6 GB RAM' GB NIC and Switch
From the switch is one hop to a GB router and out to a 10 MB pipe which leads to our datacenter 30 miles away. The swf on this side just gets the 2 cameras, sets the quality to (0,80) and mode to (640,480,25,false) (I have played with these settings a little) and creates 2 lives streams on the FMS.
The FMS:I am running Flash Media Interactive Server 3.5 on my own server with two 3.6 Dual Core Xeon processors and 4 GB RAM. This server resides in a Datacenter and has a 100 MB burstable pipe. From the FMS administration console I am barely using 4MB total bandwidth, 1% CPU usage, 2% RAM.
The subscribing computer:I have used many different types of hardwired PC's within the same LAN and outside the LAN, results are the same.The swf on this side just creates 2 new video instances and attaches the 2 netstreams to them. They are placed side by side and the height and width of these videos are undefined.
Can Flash Media Server 3.5 do the following?. Can it take multiple live streams?. Is it possible to control the ip streams - by using API's in to the Media Servers?.
I own a site like ustream/justin where users can register and broadcast their channels using FMLE. Sometime I need to ban broadcasters after I receives any complaint against any channel. I do them on website, there is no issue in that. But how to do that on server side at FMIS. I need to do it bcause the stream users are already watching the channel page before it got banned, they still can watch it till they do the refresh. So I need something that can stop the Live Stream of that particular channel on FMS server too. How can I supply stream names to main.asc that should be banned or not to allow publishing without restarting server each time.
I've read the reference here,but it seems to me that I can only make it work with live OR recorded videos.How can I make it work with both live AND recorded videos?
I am developing an application where I need musicians to play together and I want to have an audience listen to it. I have created my publisher clients and they can create the streams, but now I want to take those multiple streams and combine them so that you can hear the guitar, singer, etc. all together.
I wanted to know if there is any limit on the number of live streams that a client can connect to?For example, there are four live streams s1, s2, s3, s4 being published to FMS, can a flash client subscribe to all the four streams at the same time?If yes, what is the maximum number of streams that a client can subscribe to and what are the trade-offs?
I'm doing some tests with FMS and live streaming, but I observe quite long delays. When the stream is first accessed, the latency is around 3-5 seconds, which is acceptable. But as we watch the stream for about 30 minutes or more, the latency grows to around 20 seconds, which is just too much. What settings should I look at to keep the latency / delay minimal?
We have installed FMS and have used it for a live streaming video event.The event lasted an hour and FMS worked great.How can I get statistics on that live stream? I'd like to know how many people saw the video, and how many people were watching at one time.
I am able to record live streams on server side. Now I am looking for an option to play recorded streams on server side when no one is publishing a live stream. Currently I am able to record all live streams that are currently being published in /opt/adobe/fms/webroot/live_recorded Folder. All the recorded streams are saved in stream.f4v format. I want to change main.asc in livemyapp folder in such a way that if any one is not publishing live streams of the name "abc" then automatically the client is served with the previously recorded abc.f4v in his browser.
Here is main.asc /* * application.onAppStart:* is called when application load. It contains Live (out of the box) * application specific initializations. */ application.onAppStart = function(){ // Logging trace("Starting Live Service..."); [Code] ....
What should I write in main.asc so that if a client is requesting to watch a stream and if that is not being published at the moment, he should be served the recorded version of that stream.
I wanted to know if there is any limit on the number of live streams that a client can connect to? For example, there are four live streams s1, s2, s3, s4 being published to FMS, can a flash client subscribe to all the four streams at the same time? If yes, what is the maximum number of streams that a client can subscribe to and what are the trade-offs?
Is it possible to limit the length of live recorded video stream to N minutes/MegaBytes by SSAS in FMS? If the aggregate size of stream outcomes the limit,always make the recorded video file the last N minutes/MegaBytes of the live show? remove the video file and record from the beginning when arriving N minutes/MegaBytes?
My Purpose is to record live streams on server side and play recorded files later. What I have done is -
1. Copied All files of applications/live in some safe location. 2. Copied all files from samples/applications/live to applications/live folder. (Deleted main.far from live folder) 3. Restricted SWF and HTML to mydomain in these files - allowedHTMLdomains.txt and allowedSWFdomains.txt 4. In main.asc I added these line in the end var mystream;var intervalID; [Code] ..... 5. Then I restarted FMS and tried streaming using FLash Media Encoder. I was able to live stream and then i stopped it. 6. A FLV File was recorded in application/live folder with the stream name that i used in encoder.
I am able to view live video on my domain as well as some other domain, that means allowedHTMLdomains.txt and allowedSWFdomains.txt did not worked. Another issue is that I am not able to view recorded video after I stopped encoder but I was able see live video before stopping. I am using jwplayer to view the video and using flashvars streamer (rtmp://xx.xx.xx.xxx/live) and file(abc) to view the live and recorded video.
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.
I have Flash Media Streaming Server 3.5 (not Interactive) running on RHEL5.5 x86_64 Linux.All is working well, however how do I prevent unauthorized access to connecting to the live stream and streaming content?How can I setup the server to require a user and password to stream live media to the server?I am new to this product and I have been reading some documentation but I have not found a clear cut answer on how to force a username and password to connect to the server to stream live content only.I am using the Adobe FMS Apache install, what files need changing?[code]I want to lock down a person from connecting to the server on the public internet and starting a live stream?Can this be done with a user name and password?
I'm running Flash Media Streaming Server and have only been serving VOD up until now. I had my network administrator open up port 1935 to the outside world during the setup process and now I can't remember if that was actually required for streaming VOD to clients. Most documentation I've read says that this port should be open, but I seem to recall reading something at one point that suggested it wasn't necessary.
I've just started messing around with publishing live streams using Flash Media Live Encoder to the Flash Media Streaming Server. I have that working without issue but was surprised to find that no authentication is required before a client running the live encoder can publish a stream to the Flash Media Streaming Server. An authentication module is available however it only works with Flash Media Interactive Server and Flash Media Development Server.
If I leave port 1935 open to the outside world, there would be nothing to stop anybody anywhere from streaming video via my server. Anyone else running a default install of Flash Media Streaming Server and with port 1935 open to the outside should see that this is true of their setup as well. I'm wondering if I can safely close port 1935 without limiting the functionality of the server or if there's some way I can require authentication prior to publishing a live stream even though I'm not on the four-and-a-half-times-more-expensive edition of the product.
My rtmp client connects to the server ok and rtmp data flowing ok for about 4hours, in the wireshark trace I can see that the server just stops sending data roughly after 4hours. The server version is 3.5.1, and I also try it on a 4.0 server the data stops coming from the server as well after 5+hours. There are no errors or any indication of session disconneciton in the diagnostic logs. I have also looked thru the settings in applicaiton.xml and server.xml I just don't see any obviious reason for the issue. I do send rtmp Acknowledgement to server after the client receives "window size" bytes, and the client sends ping response to server.
We (the university I work for) want to add an IP camera to the top of a building (so it has to be IP, we can't put a machine up there, so USB is out of the question) to stream a live view of the quad. The problem is, I can't find a way to stream any IP Cameras through the flash live encoder. I tried a camera by Axis, but their capture driver only supported MJPEG which the live encoder does not.
