Media Server :: Embed Cue Points Into A Live Stream?
Sep 26, 2011
Does anyone know how to embed cue points into a live stream?I have been searching around and trying to figure out how to make it work properly.I have played around with stream.send functions and onmetadata.It works just fine for pre-recorded files with embedded cue points.But I am having problems getting it working with a live dvr stream.It also seems if you modify the metadata keyframe using the stream.send("@setDataFrame"... while you are appending to a file, that the metadata change is only in memory, it does not get flushed to the file.If you stop and restart the stream and start appending the new metadata is not retained.
I am using the dvrcast application to serve and record the streams.The stream is recorded over a period of time, but recording is started and stopped.So the file is actually appended to instead of just over writing.So the problem lies in the metadata, if you actually want to know the exact time something happened and there is a break in the stream there is no way to calculate the actual time.So my thought was ever time the stream is appended to add a cue point that contains a date time stamp when recording began, so the actual time can be determined by calculating the difference between the last time stamp/cue point and the time elapsed.
Also I believe all of this only applies to flv files for f4v files the process would be completely different.
I have install the Flash Media Server and Flash Media Live Encoder. Everything run perfectly when I test the Live Stream through localhost, but if I try to embed to another machine, it is failed.
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 build a client side application where is only a FLVPlayback2.5 component and a short AS3 script.

My Encoder is setup with three streams: Vid: 500 kbps - Audio: 48 kbpsVid: 800 kbps - Audio: 48 kbpsVid: 1500 kbps - Audio: 48 kbps I start the encoder and everything looks fine in the log. In my browser (Safari or Firefox) I go to my html site and the stream starts after 6-8 sec. But anytime with the lowest bitrate 548 kbps and nothing look like the stream is switching to another bitrate. I tried it with the smil playlist and the result is the same. Only the lowest bitrate is plublished.
I'm having a problem with recording a live webcam stream. The last few seconds of the stream is getting cut off. The recording is stopped with the following piece of code:
when i try to live stream with FMS! I can stream video with Flash media live encoder to the server but when i create the player to recieve the livestream from server,i can not recieve the live stream,can anyone give me a step by step tutorial of how to do it?
I'm trying to stream a HDS live multi-bit stream, it seems to push to the FMS but my player doesn't display the stream.Are these settings and files correct? The documenation is confusing on what and which files need to be edited and/or created.
Encoder settings: Bit Rate: 150,500,700 FMS URL: rtmp://myserver/livepkgr Stream: liveevent%i?adbe-live-event?liveevent
FMS 4.5
I see the following directories being created when I start encoding and each directory has a single file with a .stream extension in them. Are these correct? fC:FMS-HOMEapplicationslivepkgrevents\_definst_liveevent1[code].....
'URL missing from Media tag' on FMS4.5 HTTP Live Stream playback.I have spent a whole day trying in vain to publish f4m live http streams from FMLE using FMS 4.5, and almost everything I try results in the error .The F4M document contains errors URL missing from Media tag...in both Flash Media Playback and the fms videoPlayer app.Other people seem to have seen this and solved it, but I've found nothing that helps. I have tried to publish a single stream, and with multiple bitrates. For the latter, I followed the Adobe video tutorial as follows:
Multiple bitrate live ================ I'm publishing 3 streams from FMLE, using FMS URL: rtmp://[serveraddress]/livepkgr[code]..........
Beside Flash Media Encoder, can I use a live stream from Windows Media Services?We have live streaming with Windows Media Server, but now want also offer to mobile devices, but we dont re-encode the entire streams (tvs) again, it would be great if we can use a stream from windows to tunnel it to flash media server.
One server - is streaming server with Flash Media Interactive Server 3.5that host the application with asc files in FMS application directory.Second server - is the IIS web server that host thehtml,aspx,swf etc.. files.So basically i heve swf file on one server that have to connect to live streaming via rtmp on different server with different ip address.I did not find any clear explanation on this crossdomain rmtp issue.ys only HTTP can use crossdomain.xml policy filebut not rmtp.So what policy security procedure need to be done in order to enableswf file hosted on one server to connect and show rmtp live cam broadcasting from another server?
Somebody I know can't watch because they have a proxy server.The nc.connect() call to get the live stream fails because it goes direct from AS3 to FMS and doesn't go through the proxy server.
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 purchased Flash Media Streaming Server Interactive edition in order to have the security featuers of not allowing unauthorized connections streaming live content to the server. Is there a document with procedures that details how to make this happen, the allowedHTMLdomains.txt does not work when you place in IP ranges that you do not want connecting. I need some help just to figure out a way to keep someoen from connecting to the server and not streaming live content. Has anyone configured this in Linux because the documentation is mainly for Windows. Any help/advice would be great since this seems to be a common problem for anyone who runs Linux.
I'm new to Adobe Flash and I'm just trying out the Flashe Media Server 4.5 to stream live video on a local machine. I'm using a FLME 3.2 to capture the video from my digital camera, which works fine, and I can connect to the server with no worries as well. But I have issues streaming the content in the Sample Video Player that comes with the server.

I've also tried playing some sample videos on it. it even refuses to play those. What could be the problem??
I Need to Broadcast 20,000 to 40,000 Live Streams.! (Bitrate : 128Kbps / Viewers Per Stream Apprx-10 Server : Adobe FMS Server Amazon EC2 Instance - Bandwidth Apprx 100mbps)My Question is1. How Many Concurrent connections Possible for one Adobe FMS Server? (Amazon EC2 Instance)2. is this possible to use RTMFP for this process? (20,000 Connections Via Amazon Adobe FMS Server EC2 Instance )3. if Possible Over RTMFP then How Many Developer Keys Need for this Operation. (or) Pricing Details for the Developer Key. (or) Any Separate Key[s] Available For Amazon EC2 Instance?
I have a HD Camera streaming a live feed through FME 2.5 to FMS 3.0 using the VP6 codec and it works fine. I have now been trying to get the same stream running via H.264 and althogh FME 2.5 connects to the FMS 3.0 server and the stream starts with FMS 3.0 reporting the stream no problem. The Client application crerated with Captivate 3 using Flash Player 9 for publishing no longer dispays the video. Switching back to VP6 works again.
I'm running the Interactive Flash server 3 and I'm wondering is there a way to give people a user & password to limit who can live stream into the server.I can do this with the Real server and Windows media fairly easily but having problems figuring out how to on the flash server.Currently if you have the Servers IP and the flash encoder you can stream with no Username or password required. I would like to restrict this.
i have an urgent question for the following purpose. We plan to develope a solution consisting of a sender software for streaming live video to the streaming server. Now more than one client should be able to connect to the stream of the server. Because the different clients are connected with different bandwidth rates the server should be able to convert the video stream (e.g. the video width and height, framerate and quality) on the fly. Maybe a client with a better connection than DSL should get the video in a resolution of 640x480, a DSL client should get the video in 352x288 and a client with ISDN in 176x144.
Is there a possibility to do this with the FMS server on the server with server-side ActionScript? Or can I limit the requested stream size on the client side? Or anything I can do?
i need to stream a live TV Online. I have a computer with windows server 2003 and i wiil instal the adobe flash media server. I need to understand whow i can do this. I am a bigginer, what is the steps for i build a flash media server.
My fmis server is 3.5.4 and I use flvPlayback to play the fms live stream.
I want to let the live stream stopping status after be load completed.but after I set the autoPlay=false, the fms live stream is not stopping status after be load completed.
However I try the fms vod stream as the autoPlay=false ,is can stop .
what's different the live stream and vod stream. why the vod stream can stop but live stram can't stop?
Is there anyone who has a HTML example (or can give an URL with a page) that has the Adobe Flash player displaying a live stream (and not a file)?There is one in the installation under "Flash Media Server Start Screen" but it was too complex for me to understand. I just need a simple example on how to display a live flash stream in Adobes own web player.
I just upgraded to FMS 4.5. I'm able to stream live event via HDS but I can't stream live events via HLS. I can use VOD via HLS but not live events. I tried access the HLS url directly on my iphone and even tried embeddeding the <video> tags in a HTML file and get the same results. What I did notice is that in my application folder on the server I only see the HDS files being created. I do not see the .ts files that I beleive are supposed to be created when streaming to HLS devices.
I'd like to push a prerecorded flv as live stream to another server, from wich clients can receive the video as live stream.
[Code]....
monitorStream.flv lies on my FMS. So from the debug-output everything looks fine. But i donīt see any video, when i play the published stream on client-side. The outgoing stream itself is correctly published.
I read a blog article http:(url......)talking about switching between different bit rate video streams of the same video content on fly.But I can not find such ability in RTMP's specification.I am wondering if such function has to be implemented by users with ActionScript?
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.
