Detect live stream

Can somebody please answer this question to me:
With the Flash Media Streaming Server (not the interactive
version), is it possible to detect if a live stream is running?
I want to show an overview of several live streams on one
page.
The ones that are not running should show as "offline". The
others should show an online thumbnail.
I don't want the visitors to have to go to all of the pages
only to see that the stream is offline.

Hmmm... I've been searching for an answer to this too. Want to put a "Not Broadcasting" swf up there when not streaming but FMS doesn't give the necessary messages. Would think this would be a pretty standard thing to want to do.
Here are the messages FMS 3.5 fires when I pull up my client app and start and stop my encoder a few times:
NetStream.Play.Reset (Playing and resetting stream)
NetStream.Play.Start (Started playing stream)
NetStream.Play.PublishNotify (stream is now published)
NetStream.Buffer.Full
NetStream.Buffer.Empty (15 secs or so after stopping the encoder)
NetStream.Buffer.Full (15 secs or so after starting the encoder)
NetStream.Buffer.Empty
and so on...
FMS should broadcast messages to the effect "Stream stopped" and "Stream started".
There are so many other messages broadcast. Wonder why these aren't implemented?

What i need to confirm is: ........................................................ see the next post of mine. (for Problems need to be Resolved)

Problems to Resolve:
Problem#1) - Countdown Timer to the designated Date for Live-Broadcast-Event yet to take place.
Problem#2) - Detect End of Live Stream on FLVPlayback with FLVPlayback.isLive = true;
Problem#1 Description:
I need to pinpoint the Logical TimeSync Exception, i am still unable to figure out. That is I'm using a webservice in my Application to Synchronize the Time with the actual ET (eastern time) with accomodation of auto-adjustment for EDT GMT-4 (eastern daylight time) & EST GMT-5 (eastern standard time), times. I am using the zipcode: "10012" to pass it to the Web Service in urlRequest object, to retrieve the Current ET eastern time according to EDT & EST time settings for Manhattan/Brooklyn areas or others within New York, NY 10012.
Currently the Web Service is returning accurate date/time based on local EDT GMT-4 daylight time.
Is there some defined set of dates for EDT & EST times for New York region that I can check for to ensure the correct Dates/Times for Eastern Time in New York area ??? I am using NY zipcodes because i am sure to get correct ET values.
The Major Problem Part: is I need to correct the time by 2 seconds or approx. 2 secs, some millisecs.
When I retrieve the Time Value from WebService, it lags behind for 2 seconds as compared to DateObj i create using computer's local time, on my Windows XP Service Pack 2 with Automatic Updates turned-on. And I'm sure about my Windows will be having latest updates for Time Management already installed. I also added the 2 secs. to the TimeSync(ed) Date to make correction to this Date obj.
I call my custom fucntion addSeconds(dateObj:Date, secs:int) to add 2 seconds to the Date by Converting Seconds to Milliseconds.
Please comb through the as code in files attached and Help Me Out !!!
Problem#2 Description:
Secondly I need to Detect the End of Stream state while using FLVPlayback component, an rtmp:// live Stream from FLASH MEDIA SERVER.
I need to Play a YuMe Post-Roll Ad when Steam Finishes/Ends.
Live Broadcast Stream Event starts every night on Wednesdays & Saturdays exactly at 10:59 PM EDT GMT-4.

Dynamic Bitrate Switching on Live Stream

I have FMIS 3.5. I've installed it with pretty much all the default values. I haven't changed any of the settings in either the LIVE or the VOD applications.
Dynamic Bitrate Switching is working well for VOD, but not working at all for LIVE streams. Doing a regular bandwidth detection on both the LIVE and the VOD applications give similar, high bandwidth results. However, the LIVE application NetStreamInfo.maxBytesPerSecond is showing a very low bandwidth capability of around maxBytesPerSecond = 19016, where as for the VOD its achieving around 637110. I can play a single LIVE stream of a high quality smoothly without any error.
I don't know if this is relevent but I'm getting some error messages occassionally in the log of the live application saying : Dropping application (live/_definst_) message. Clients not allowed to broadcast message. These messages aren't consistent, and don't coincide with trying to use bitrate switching.
I have tried downloading the Adobe sample StreamSwitching.fla and it won't play the LIVE streams at all. Using the opensource Longtail Video player it just always defaults to the lowest stream. Here is an example: http://www.ltscotland.org.uk/testbed/live/livestream2.asp
Can anyone suggest what the problem might be here? And any possible solutions?

Thanks,I have read that article. Based on that article the NetStreamInfo.maxBytesPerSecond is not an accurate measurement to base dynamic switching on. This seems to be the basis of the bitrate switching in both the longtail player, and the adobe examples that I have tried. That article suggests using the dropped frames property, in conjunciton with bufferlength to determine if switching is neccessary. Unfortunately I can't seem to find a player online which handles this successfully. That being said, I can't believe I'm the only person trying to implement dynamic bitrate switching for live streams so surely there are some players out there which can do this successfully? If anyone knows of any code available which does this successfully I would appreciate knowing where! The examples provided by Adobe https://www.adobe.com/cfusion/entitlement/index.cfm?e=fms35 unfortunately don't work either.

Reading video size without onMetaData on live stream.

Hi,
I am a Flash developer and practically know nothing about
FMS.
We encountered a situation when our encoder (not Adobe's one)
doesn't inject metadata into a live stream. So, there is no
onMetaData on the stream. When stream is in 16x9, our players don't
resize the stream according to it's ratio and always display it in
4x3.
Is there a way to read width and height of the video even
though there is no metsdata? Perhaps a method that can be invoked
via responder similar to getStreamLength.
Video is streamed via Akamai.
Interestingly enough when we view the same stream in Akamai
player - video is resized to the proper dimensions/ratio AFTER a
few seconds. Obviously Akamai has a mechanism to detect video
dimensions.
Any help will be greatly appreciated.
Thank you.

My ignorance is the problem.
AS3 Video class has videoHeight and videoWidth properties
that can be used in case onMataData is not called.

HTTP Live Streaming for Apple IOS devices

HI,
We have installed FMS 4.5, including Apache 2.2, on a 64-bit Windows 2008 R2 server following the instructions given in the video that can be viewed here:
http://www.adobe.com/devnet/flashmediaserver/articles/install-verify.html
Browsing to the test page for the server works fine for HTTP Dynamic Streaming and RTMP Dynamic Streaming samples. However, when we try to use the HTTP Live streaming samples on the test web page on an iPad via AnyConnect, we only see a blank page with a small Abobe Flash icon in the top left hand corner which is basically saying that Flash has been detected on the page and is not supported by the iPad.
The above video shows HLS working on an iPad with no additional installation steps. Can anyone hep?

Found the answer
The home page on the Adobe server has an error in its javascript.
if (uagent.search('iphone') != -1 || uagent.search('ipad') != -1) {
should be
if (uagent.search('iPhone') != -1 || uagent.search('iPad') != -1) {
....capital P's.

Live Stream Listener

I am new to Stobe Media Playback, however i've managed to customize my player with posters. My player was originally set up to auto play a live stream but the auto play feature disbled the poster feature. I was wondering if there was a way to code my player to listen for the live stream from FMS and automatically start playing the live stream. Thank you in advance for your time consideration!

Hi,
Auto play disables the poster frame, as expected - it jumps directly to playing the video.
If I understand corrrectly, you need a way to tell if the live is online or not.
In the live case, there is no out-of-the-box support in SMP for detecting if the live has started. You will have to write your own code to see if the server is streaming.
I suggest to make an improvement request in our bugtracker: http://bugs.adobe.com/jira/browse/FM - raise it as an issue . It will be better tracked and it will have a higher chance to being considered for fixing.

What is the problem? From media server console I can see 2
connection for 15 minutes and after that it drops to 1.
I have tested it with medium and low bandwith.
Any help is appreciated.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

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 one.

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.M

Hi 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.     [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>
Thanks

How can I do live streaming with a Mac Book Pro 2011, using a new model of Sony HD camcorder which does not have firewire out/input? it comes only with a component video output, USB, HDMI and composite RCA output?

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?
Thanx

I 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...
thanx

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

I would thow something like this.
<result>
<level>status</level>
<code>NetConnection.Call.Success</code>
<timestamp>7/13/2011 10:52:05 AM</timestamp>
<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 can I do live streaming with a Mac Book Pro 2011, using a new model of Sony HD camcorder ..that doesn't have firewire out/input?

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?
Thanx

I 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...
thanx
