Live streaming
I have tried just about everything with this. I have to say
that the documentation for VOD is excellent but there is very
little coherent documentation for the live service.
How do i tell the application that this is a live stream that
I want it to connect to? I know there is a parameter called isLive
that can be set to true or false. How do I do that? I thought you
did not have to write code for the built in apps? Or am I totally
off base?
Anyway, I am streaming audio from flash media encoder 2.5 to
my flash media server 3. All I want to do is publish the live app
like I do the VOD app, so end users can access it from a web
server.
Im sure you have already solved this but just in case you haven't check you JAVA settings. The live stream uses java.

My IPad cannot download live Tv from skygo. I have no problem with my lap top so I assume the broad band is okay. Can anybody suggest why the live streaming will not work on my iPad .
Are you using the Sky Go app to try and watch it ? If so are you logged in with your Sky account ?
If you are using the app then you could try closing the app completely and see if it works when you re-open it : from the home screen (i.e. not with Sky Go 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Sky Go app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
If that doesn't work then you could try a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot. -
Doubt regarding HTTP Live Streaming for windows phone 8.1 silverlight app?
Hi,
I am developing a Windows phone 8.1 silverlight app.
I want to add live streaming youtube channel , thats why I used https://phonesm.codeplex.com/ this link as a reference , and I am able to play the links given in the samples, but I am unable to play my link https://www.youtube.com/watch?v=p2GF-QQS6n0
I am getting 3108 unable to play media error with my link,
My question Is there any need of streaming server ?
If yes can anyone help how to create the streaming server.
Thanks....
Suresh.MHi Suresh.M
As I can see a similar question on the Windows Phone Streaming Media discussion:
https://phonesm.codeplex.com/discussions/545737
You may need check into the call stack and find out what is the root cause, for instance if there any chance that your phone cannot reach to the video address, and did you enable some network capabilities, etc.

HDS live streaming to Flash not working
Adobe Flash Media Server 4.5.5 r4013
Windows 2008
Sources:
http://help.adobe.com/en_US/flashmediaserver/devguide/WSd391de4d9c7bd609-52e437a812a3725df a0-8000.html
http://www.adobe.com/devnet/adobe-media-server/articles/live-multi-bitrate-video-http-flas h-ios.html
Live streaming a single or multi-bitrate video over HTTP to Flash does not work. I have followed the instructions on the 2 sources listed above repeatedly, but I can’t get live streaming over HTTP to Flash to work. Live streaming to iOS over HTTP works with no problems (single and multi-bitrate streams).
I have tried the troubleshooting steps from the following:
http://help.adobe.com/en_US/flashmediaserver/devguide/WS0432746db30523c21e63e3d12efac195bd -8000.html
Troubleshoot live streaming (HTTP)
1. Services window (Windows): Flash Media Server (FMS), Flash Media Administration Server, and FMSHttpd services are running. ✓
2. Verified that the request URL is correct. ✓
3. Configured ports:
a. Configure Apache to use port 80. Open rootinstall/Apache2.2/conf/httpd.conf in a text editor. Change the line Listen 8134 to Listen 80.
b. Configure Flash Media Server not to use port 80. Open rootinstall/conf/fms.ini in a text editor. Remove 80 from the ADAPTOR.HOSTPORT parameter so the parameter looks like the following: ADAPTOR.HOSTPORT = :1935 ✓
4. Placed a crossdomain.xml file to the rootinstall/webroot directory. ✓
5. In Flash Media Live Encoder, select the Encoding Options tab, choose Output from the Panel options menu, and verify the following:
a) The value of FMS URL is rtmp://fms-dns-or-ip/livepkgr. If you’re testing on the same server as Flash Media Server, you can use the value localhost for fms-dns-or-ip. ✓
b) For a single stream, the value of Stream is livestream?adbe-live-event=liveevent. ✓
c) For adaptive bitrate streaming, the value of Stream is livestream%i?adbe-live-event=liveevent. ✓
Flash Media Live Encoder uses this value to create unique stream names. To use another encoder, provide your own unique stream names, for example, livestream1?adbe-live-event=liveevent, livestream2?adbe-live-event=liveevent.
The encoder is showing all 3 streams being published and streaming.
6. Check Administration Console: the livepkgr application and the 3 streams are running. ✓
7. Check the logs for errors. Flash Media Server logs are located in the rootinstall/logs folder. The master.xx.log file and the core.xx.log file show startup failures. Apache logs are located in the rootinstall/Apache2.2/logs folder. X
a) core00.log: these errors did not occur every time that I tried playing the live stream but these are the only relevant errors in the logs.
1. 7968 (w)2611179 Warning from libf4f.dll: [Utils] [livestream2] Discarded all queued Media Messages received before first Video Keyframe Message
2. 7968 (w)2611179 Warning from libf4f.dll: [Utils] [livestream3] Discarded all queued Media Messages received before first Video Keyframe Message
b) edge00.log:
13:33:57 4492 (w)2641213 Connection rejected by server. Reason : [ Server.Reject ] : (_defaultRoot_, _defaultVHost_) : Application (hds-live) is not defined. -
c) Apache-Error:
1. [warn] Checking if stream is disabled but bootstrap path in event file is empty for event:livepkgr/events/_definst_/liveevent stream name:livestream
2. [warn] bootstrap path is in event file is empty for event:livepkgr/events/_definst_/liveevent stream name:livestream1
As I mentioned, everything works on iOS and FMS seems to be creating all of the stream segments and meta files:
a. The 3 streams are being created in: HD:\Program Files\Adobe\Flash Media Server 4.5\applications\livepkgr\streams\_definst_
b. FMS is creating the following files in each stream folder (livestream1, livestream2, livestream 3):
1. livestream1.bootstrap
2. livestream1.control
3. livestream1.meta
4. .f4f segments
5. .f4x segments
The appropriate files are also being created in the HD:\Program Files\Adobe\Flash Media Server 4.5\applications\livepkgr\events\_definst_\liveevent folder, in which I have the following Manifest.xml and Event.xml files:
<manifest xmlns="http://ns.adobe.com/f4m/1.0">
<media streamId="livestream1" bitrate="200" />
<media streamId="livestream2" bitrate="500" />
<media streamId="livestream3" bitrate="1000" />
</manifest>
<Event>
<EventID>liveevent</EventID>
<Recording>
<FragmentDuration>4000</FragmentDuration>
<SegmentDuration>16000</SegmentDuration>
<DiskManagementDuration>3</DiskManagementDuration>
</Recording>
</Event>
I’ve tried clearing the contents of both streams\_definst_ and events\_definst_\liveevent (keeping the xml files) after restarting the encoder, and creating a different event definst for the streams (liveevent2 for example).
We have an event in 2 weeks that we would like to stream to both Flash and iOS. Any help in solving this problem will be greatly appreciated.One step closer:
Changed the crossdomain.xml file (more permissive settings).
Changed the encoding on FMLE to vp6. Working somewhat (don't know what I did to make it start streaming through hds).
But at least now I can get the individual streams in the set manifest file to work:
http://localhost/hds-live/livepkgr/_definst_/livevent/livestream1.f4m
http://localhost/hds-live/livepkgr/_definst_/livevent/livestream2.f4m
http://localhost/hds-live/livepkgr/_definst_/livevent/livestream3.f4m
BUT when I try to play the streams through the set manifest file from http://localhost/liveevent.f4m I'm getting the following error:
"The F4m document contains errors URL missing from Media tag." I'll search the forums to see if anyone else has come across this problem.
I used the f4m config tool to make the file. These are the file's contents:
<manifest xmlns="http://ns.adobe.com/f4m/2.0">
<baseURL>http://localhost/hds-live/livepkgr/_definst_/liveevent/</baseURL>
<media href="livestream1.f4m " bitrate="200"/>
<media href="livestream2.f4m " bitrate="500"/>
<media href="livestream3.f4m " bitrate="1000"/>
</manifest>

I need to do live streaming with a Mac Book Pro 2011, using a new model of Sony HD camcorder (http://store.sony.co...ber=HDRAX2000/H) ..this camcorder model does not have firewire out/input ..it comes only with a component video output, USB, HDMI and composite A/V video output..
I wonder how can I plug this camcorder to the firewire port of my laptop? Browsing on internet I found that Grass Valley Company produces this converter http://www.amazon.co...=A17MC6HOH9AVE6 ..but I am not sure -not even after checking the amazon reviews- if this device will send the video signal through firewire to my laptop, in order to live streaming properly? ..anyone in this forum could help me please?
ThanxI can't broadcast with the built in iSight webcam... how would I zoom in or zoom out? or how would I pan? I've seem people doing it walking with their laptops but that's not an option for me... there's nothing wrong with my USB ports but that's neither an option to stream video because as far as I know through USB you can't connect video in apple operating systems ..you can for sure plug any video cam or photo camera through usb but as a drive to transfer data not as a live video camera... is by firewire an old interface developed by apple that you can connect all sorts of cameras to apple computers... unfortunately my new sony HDR-AX2000 camcorder doesn't have firewire output...

How to handle the shared LIVE stream on Facebook that already became a VOD streaming file?
Hi all,
I can share a embedded MP4 file on Facebook with facebook OG tag so that people can view the video with inline video player.
Streaming from FMS 4.5, the embedded LIVE streaming link can be http://<mydomain>/VideoID.f4m
When internet user viewing/sharing the same link on their facebook, the view the link stream as well.
When the LIVE event has been completed, the recorded MP4 file would be work as VOD streaming, link like http://<mydomain>/hds-vod/VideoID.f4m
The problem is that when people click on the previously shared link on facebook, the embedded link is the "http://<mydomain>/VideoID.f4m" that do not exist.
How can i redirect the f4m to the VOD f4m address? Thanks.You could use the Flash server Administrator API getLiveStreams() and read the xml the server throws you with actionscript on your flash
http://localhost:1111/admin/getLiveStreams?auser=username&apswd=password&appInst=application

<name>_defaultRoot_:_defaultVHost_:::_1</name>
<data>
<_0>live1</_0>
<_1>live2</_1>
</data>
</result>
Then read the data node and get the number of streams. use some actionscript if data# >= 100
then trace a message.
I haven't tried this. but i think is posible. -
How do I use multiple cameras to live stream through FME?
I am looking to live stream pool tournaments from multiple angles but don't know what software or hardware I might need. Anybody have any good how to advice or links they might share? I stream through Ustream.tv if that makes a difference. Should I look for something different? Thanks
I am working on getting just the counter working by using
the program posted previously, and I am running into issues. Periodically I get
the error:
Error -200141
occurred at DAQmx Read (Counter DBL 1Chan 1Samp).vi
Possible reason(s):
Data was overwritten
before it could be read by the system.
If Data Transfer
Mechanism is Interrupts, try using DMA. Otherwise, divide the input signal
before taking the measurement.
It seems to work better if I use cascaded counters, but I need timer 0 for
analog channels when I run this code along with the program for the other
measurements.
I have tried averaging, and selecting different values for the millisecond
timer, and these did not seem to have an effect.
I tried different DAQms configurations and "Counter DBL 1Samp" seemed
to work the best.
The program will work for a while and then it will give me the above error
message.
If I use counter 0 as a cascaded counter input, the program runs fine. If I run
this with other analog channels, it errors out because the analog channels use
counter 0.
If I use counter 1 as a cascaded counter input, it seems to work better than a
single channel, but it will still error out with the above error.
If I use only counter 1, I get the error above even faster.
Also, none of the
configurations give measurements outside the While Loop.
The only place I can add a speed dial for the front panel is within the While
Loop.
Is there someway to get the signal to continuously send out of the while loop?
I thought if I could get the signal out of the while loop, I could condition it
anyway I wanted without the program erroring out.
Any suggestions would be much appreciated.
Thank you.

How do I create a variable video delay of a live stream...
I have a live video feed from my webcam in my Flash Application. I have a second video window next to it that I want to place a variable delayed video of the live stream. Therefore, I need to save the video stream in memory/disk and create this variable delay, say 5-60 seconds. As well as, continue to capture the live stream. The camera I am using suppots H.264 encoding.
How do I create a variable length queue or buffer to hold the video stream coming into the flash application. Do I create a memory variable or write this to disk ? I have been looking over the ActionScript 3.0 documentation and I can not figure out how to code this either way ( as a memory variable or write to disk queue ).
I want to be able to change the delay, view the delay stream in slow motion and scrub through the delayed stream.
I would like to do this with out having to use Flash Media Server.
Thanks,
BobI am sure it is practically impossible to accomplish that on the client side. Although theoretically it is conceivable to use NetStream.appendBytes() but it requires an extremely complex implementation.
I suggest you look into FMS DVR capacities:

About Flash P2P live streaming from non-webcam sources
Hello, I am a university student. Our lab is attempting to work on a p2p live streaming using flash p2p features. The media source is not from a webcam but a file from a certain server, which is not directly supported by any of the 4 methods flash player offers(posting, direct routing , object replication,and multicast.) As some of the forum threads mentioned, our method is to use NetStream.publish() a stream and use send("callbackname", data) to all subscribers that have joined in a NetGroup. So we can use p2p transmission. Now here are our questions:
1. We know from MAX 2009 that flash p2p camera video multicasting implements pull-push mechanism inside which makes full use of p2p features like buffer map exchange. If we use NetStream.send() API to send non-webcam source data, will it also make use of this pull-push mechanism to spread data among all peers(subscribers) with proper data exchange?
or more detailedly,
I saw the P2P Gaming Libs at flashrealtime.com. It uses DIRECT_CONNECTIONS when creating publish-used NetStream in order to send data with lowest latency. My question is if I do not use DIRECT_CONNECTIONS, than when the NetGroup grow large (1000), will those peers that are not direct neighbors to the publisher in the same group relay data to each other using pull-push via buffer map?
2. I have written a sample app and use send() to deliver data only (NetStream.bufferTime = 0) without camera video and audio. When the publisher sends the data in a "for()" stantence for 20 times, the subscribers can only receive about 8 of them. But when I set a timer and periodically send them(e.g., 500ms), the subscribers can receive them correctly. My questions are: Is the packet loss caused by UDP unreliability? Can this be solved by setting the NetStream.dataReliable = ture? Can this totally be solved by setting a timer? How to set the delaytime property in timer? Are all data sent are orderedly received?
I'm very appreciated if you can answer my questions? thanks.1. NetStream.send() data is delivered in the order it was sent, whether in client-server, DIRECT_CONNECTIONS, or multicast mode.
2. the lowest latency will be achieved with DIRECT_CONNECTIONS. however, that isn't scalable to large numbers of recipients. the P2P multicast system trades low latency for scalability.
3. there are no plans to support a natural NetStream streaming source that's not a camera/microphone. Flash Media Server can perform that function.
4. you should never need to implement "bitmap exchange"; the object replication system handles all the communication needed to accomplish its function. typically you will divide a file into segments, giving each one an index number. object replication uses ranges internally, so the index numbers should be contiguous. nodes that have indices use NetGroup.addHaveObjects(). nodes that want indices they don't have use NetGroup.addWantObjects(). nodes that have objects will send them to nodes that want the objects. when a node receives an object, it's automatically removed from its "want" set; once the node decides the object is acceptable, it adds it to its "have" set, at which point it can answer requests from other nodes who still "want" it. eventually every node will have all the pieces and not want any. for an example, please see Tom Krcha's articles on using object replication:
http://www.flashrealtime.com/file-share-object-replication-flash-p2p/
http://www.flashrealtime.com/video-on-demand-over-p2p-in-flash-player-101-with-object-repl ication/
5. please see Tom Krcha's articles. for VOD you will probably want to use the "LOWEST_FIRST" replication strategy, as that may allow you to start playing earlier. for general file replication you'll get better sharing if you use RAREST_FIRST. -
How to play live streaming in windows phone 8.1 silverlight app?
Hi,
I am developing a windows phone 8.1 silverlight app. In my I want to show live streaming youtube channel , I think it is not possible,
Actually that youtube channel is a television channel , I want to stream that live tv in my app.(I tried to load youtube channel in webbrowser in iframe tag but it is not opening)
Anybody help me how to play live tv or live streaming in my app,
Thanks..
Suresh.MHello,
You will likely need to write a custom
MediaStreamSource that can access the media stream and parse it. Windows Phone supports h.264 natively and as long as the site serves up a media stream that contains h.264 frames you can parse it and have our built in decoder decode and display it. You
will need to have intimate knowledge of the streaming protocol used by the website that you are trying to play. You must also make sure that the website is not using protected content. IANAL so I would recommend that you have your local law professional
(lawyer) review the licensing of the website that you are attempting to connect to and stream from before continuing your development. Your lawyer can make sure make sure their licensing allows you to do this.
I hope this helps,

Hi,
am planning to develop a live streaming app using C# and xaml.
I have gone through the below sample and am able to stream the live content using wireacst camera.
Azure Media Services Live Streaming Sample
But i want to use Phone camera to stream the live video rather using wirecast camera.
How can i use that? How to get the published URL from the C# code, is there any API to get that?
Anybody please help me
Regards,
SanthoshHello,
There are no in box components that will allow you to transmit captured video from a Windows Phone device to Azure Media Services. You will need to create you own implementation. You can do this by creating a custom Media Foundation sync that can plug into
the MediaCapture element's pipeline. You will then need to modify the captured and compressed video to align to one of the two protocols that Azure Media services can use. At this time Azure Media services can use either Smooth Streaming or RTMP for ingestion.
You will need to create your own packager (or find compatible packager code from a 3rd party) to package the MP4 encoded data into the necessary format.
Here is an example of how to create a custom Media Foundation sync (please note you must write your Media Foundation components using C++ MoCOM. We do not support Media Foundation components written in managed languages):

My Maxx plays some live news videos and sometimes it does not depending on the site. I tried different video players like the MX and others to no avail. I tried on chrome
And other browsers.
Not sure which way to go with this.
Any ideas would be much appreciated.I went to a Verizon store (agent) yesterday after work and tried the S4. They didn't have a live S5, and it did play the sites I normally use. The iPhone was able to live stream it also. I think its the Razor Max that's missing whatever it needs to play those videos.... plug ins, etc....
Its mind boggling with all these phones out there.
Anyway, thanks for your input, Suzy. -
Using http live streaming to stream data from a Webcam
JavaFX 2.2 includes support for http live streaming: http://en.wikipedia.org/wiki/HTTP_Live_Streaming
How could one create a http live stream from a Webcam and thereby enable a JavaFX application to view and hear the Webcam video in realtime?Bom Dia Saille,
Eu acredito que o que você tenha hoje seja isso aqui (Desenho bem simplificado):
Hoje o que você tem é o Aplicativo do Medidor + USB Driver controlando o seu medidor. Basicamente, sua aplciação está dividida em três camadas:
Aplicação - Onde estão as funcionalidades principais do programa (interface com o usuário, apresentação de dados, geração de arquivos, etc.)
VISA - Uma arquitetura de Software para controle de instrumentos. Basicamente, ele se comunica com o Driver USB para poder enviar e receber pacotes de dados através do barramento USB.
Device Driver - Intruções de SW de baixo nível para controlar um periférico através de um barramento.
No desenho, eu aponto duas camadas onde você pode tentar atuar para automatizar suas medições:
Aplicação - Você pode usar o VI Server para controlar o Aplicativo do Medidor (Se este aplicativo tiver sido desenvolvido em LabVIEW, o que eu suponho ser verdade). No entanto é necessário saber se o desenvolvedor do produto permitiu isso (Veja Using VI Server to Pass Data Between a VI and a LabVIEW Executable). Outra alternativa é conversar com o fabricante para ver se ele desenvolveu alguma API (Application Programming Interface) para que você consiga controlar o instrumento diretamente.
VISA - O LabVIEW Fornece uma API chamada NI-VISA para poder enviar e receber informações através de diversos barramentos (Veja Serial Instrument Control Tutorial)
É possível acessar o Driver diretamente também, mas eu não recomendo. O resultado não compensa o esfroço!
Espero ter esclarecido suas dúvidas e espero que você tenha sucesso na sua aplicação!!
Atenciosamente.
