Media Server :: How To Stream Live Audio And Metadata
Aug 13, 2010
i'm trying to build some kind of online radio. Therefore i'll be streaming audio (mp3) in real time. i have a play-list on my server and the idea is for this play-list to play all day long, but on the client side the user can only do play and stop the music.
The problem is when one music stops and the next one starts i need the server to send not only the new audio but also all the info about this file: duration, author and music name, this way my player can show a play /stop and all the info about the current music playing.Until now i've only come across with video live streaming, but very little information on how to do a live transmission of audio.
ps: the only info on streaming audio that i've found so far is about audio on demand, but the way i want things to happen the client can't chose the music.
insert captions into a live flash video stream.[URL]this example uses a Flash client app wich can invoke something like video_nc.call("sendDataEvent",null,inputfield_txt.text);How can do this without any Flash client/environment ? (I of course still use an FMS 3.5) I would like to use a python (or php...whatever) piece of code to extract caption from VBI in the incoming video stream and insert it in the flash stream.
I need to improve the uptime of a 24/7 live audio stream. Periodically, the connection between FMLE and FMS (3.0.1) is broken and FMLE cannot reconnect. FMLE shows NetStream.Publish.BadName error. How do I prevent this error and get FMLE to automatically reconnect every time? What other measures can be taken to improve the uptime of a live audio stream publishing from FMLE 3.1 (Windows) to FMS 3.0.1? Also, are there any improvements in FMS 3.5 that will help with uptime?
HI installed flash media server 3.0.4 on a Windows 2003 server.I am using the default LIVE application and broadcasting to it using FME version 3.0 Inside FME I choose MP3 as the audio codec, stereo and 128kbps When I watch the stream everything works fine but after a minute (sometimes 2 minutes) the sound disappears and I can only see the video run.If I refresh the page that contains the SWF that plays the stream then the sound works again but then again after a minute the sound stops and only the video continues to play. It is important to say that this only happens when I play a live stream from a server that is located outside of my local LAN. If I play a stream from my development FMS server in my local LAN this problem doesn't happen using the same SWF and same settings in FME.Moreover, if I use the nellymoser audio codec then everything works fine and this problem doesn't happen also. The thing is that I want to broadcast a live event and it is very important that the audio sounds good (stereo and 192kbps) and if I use the nellymoser codec the results aren't that good.
I did a live stream last week using 282,482,832,1500Kbps streams. What would cause the audio to get out of sync with the live video stream? I'm trying to determine if it was bandwidth related, cpu/memory issue on the FMIS 4.5 server, or an issue with encoding PC exceeding it's limits?
I currently use FMS 4.5 to steam Live Technical Videos.
Hooked into Flash Media Live Encoder is a Roland VR-5 which lets me have multiple Camera switching.
I want to braodcast also a few live Audio only streams. I could easily use the VR-5 which in turn has a Behringer Audio Mixer attached to allow up to 16 Audio devices to be mixed in, and then just turn off the Video option in Flash Media Live Encoder but:
I don't want to have to put a video window on the Webpage. I just want an Audio controller.
So how can I use FlashMedia Server to just stream a live Audio feed?
I need to merge multiple live audio streams into a single stream so that i can pass this stream as input to VOIP through a softphone.For this i tried the following approach:Created a new stream (str1) on FMS onAppStart and recorded the live streams (sent throgh microphone) in that new stream.
Below is the code : application.onAppStart = function() {
I currently have two connections with two separate streams. They both hit the same fms 3.5 server. One connection transfers live audio and video. The other one is used for remote objects. Sometimes when viewing the audio and video stream with a slower internet connection, the stream for the shared objects disconnects. I think it is a bandwidth issue. Is there any way to set the priority of the streams? I think this should allow me to set a higher priority for the shared object connection so it won't disconnect.
I'm streaming live video through FMS 3 and passing the streams to another FMS application to be recorded. While recording, I inject some custom metadata into the stream. Once recording is finished, I move the flv to another location and update my database with the metadata contained in the stream for later reference. All this succeeds without a problem.
However, only sometimes, the default 'duration' metadata (note - I never mess with the duration metadata, merely insert my own fields that are required for other reasons) is COMPLETELY wrong
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].....
I've had FMS running on my local machine for a while and have had a little experience writing FMS apps, but I've just tried recording audio for the first time using the standard vod application and I keep getting a "Write access denied for stream" error. My AS3 code is copied and pasted for various examples and am confident that it works.
I'm running Windows XP service pack 3 & FMIS 3.5.
I've had a look at the vod/media directory and under windows->properties the read-only attribute is ticked. Every time I un-tick this it reverts back to being ticked. I've googled this and MS say that most programs ignore the read-only attribute and that it only really applied to files. I've also tried the MS fix for setting the read-only attribute via cmd and still no joy (doesn't fix read-only attribute or FMS recording the audio after setting via cmd).
I've also tried our dev server install of FMS (running under linux) and am getting the same results.
Here's my AS3 code...
private function initApp(event:Event):void { removeEventListener(Event.ADDED_TO_STAGE,initApp);
'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.
