Saving Live Stream

Hello,
I just bought QuickTime 7 Pro because it allows you to save streamed video. We have a live camera feed to the web of our meeting room and I want to be able to save the stream as a QuickTime Movie. I right click the movie on my web browser and choose "Save as QuickTime Movie" and it only saves the link to the stream. I could have sworn I read that it would save the ACTUAL stream, not just the link. For reference sake I am using a Polycom VSX 8000 to broadcast the streaming video to our subnet only.
Can anyone help me out with this? Thanks.

Streaming media isn't cached so there is nothing to save but a link to the stream.
Screen recording software can capture the audio and save it in various formats but you run the risk of copyright violations. Since you say the file is your own obviously this doesn't apply but I mention it for others.

Pls playlist of mp3 live stream doesn't work properly, what to do?

Can others confirm the following issue with a live mp3 stream on version 7.0.2.16 on windows xp (sp2):
Go to wnyc.org and click on the AM or FM live stream (32k) links at the top left of the page. They should link to either of the following urls:
http://www.wnyc.org/stream/fm.pls
http://www.wnyc.org/stream/am.pls
Open these playlists with the current iTunes for windows. You should hear a 15 second sponsor pre-roll for this NPR station, and the live stream should start after that. I only hear the pre-roll, and then iTunes skips to the next item in the library.
Do you only hear the sponsor pre-roll, and then nothing OR does it work properly for you? If not, what to do?

Reboot your computer in Safe Mode and then try to reset all Skype settings.
Go to Windows Start and in the Search/Run box type %appdata% and then press Enter or click the OK button. The Windows File Explorer will pop up. There locate a folder named “Skype”. Rename this folder to something different, e.g. Skype_old.
Next go to Windows Start and in the Search/Run box type %temp%\skype and then press Enter or click the OK button. Delete the DbTemp folder.
Reboot in normal mode and try to start Skype.
N.B. If needed, you will still be able to re-establish your call and chat history. All data is still saved in the Skype_old folder.

Mirroring a live stream

I need to take a live stream from a camera attached to server
A, and mirror it to server B, so that local users on server B can
view it. I don't want it saved to server B, I want it to remain
live. I'm using a push model - server A sets this up.
I think that if I create a netconnection on server B looking
back at server A I can use it to add a netstream attached directly
to server A's camera. Is this correct?
I am as yet a very inexperienced Flash developer, and my
efforts are impacted by the fact that I am now modifying someone
else's code using someone else's design patterns.
Thanks.

Right.... server B needs to make a netconnection to the
server A application, and then play the stream using Stream.play.
Making a netconnection in SSAS is almost identical to CSAS.
See the docs for the server side netconnection and Stream
classes... there are some examples in there.

Let clients record & save part of live stream

Hi,
I'm looking for a solution where clients watch a live stream video and can record part of this stream while watching and save this recording to disk. I can think of several solutions but not sure if any of them is possible:
- The selected part is recorded locally and saved through FileRefence.
- The selected part is recorded with FMS though a second NetStream and saved with a unique ID. The user can retrieve the recorded video by download.
- Start-time and end-time of the recording are send to the server where some script extracts the requested video from the live stream recording file and return it as a download.
Would any of these solutions work and what would be the best approach?
Thanks!

Thanks for the reply.
I'm indeed going for the last option, where the live stream is being recorded as FLV on the server and FFmpeg copies the requested part and converts it to MP4. Still need to do some testing and optimalisation but this seems to work quite well.

Publishing multi-bitrate live streams for iOS

I'm having difficulties publishing multi-bitrate live streams that can be viewed on an iPad/iPhone.
I'm running Flash Media Server 4.5, and have carefully followed Adobe's Tutorial on streaming live media (http) using hls found here: http://help.adobe.com/en_US/flashmediaserver/devguide/WSd391de4d9c7bd609-52e437a812a3725df a0-8000.html#WS0432746db30523c21e63e3d12e8340f669-8000
After completing the above tutorial, the video can be seen just fine on my desktop computer via the flash plug-in, but it's not working in iOS...
When I go to what I believe to be the proper URL, (http://myflashmediaserver.net/myevent.m3u8), I get an error message on my iPhone and iPad saying "The operation could not be completed".
I have created two set-level manifest files (one .f4m and one .m3u8) for the live stream using the Set Level F4M/M3U8 File Generator and saved them to the WebRoot directory, but alas, no love.
Any help would be greatly appreciated!
Mike

I just finished going through the short and sweet tutorial on the Adobe website "Capture, encode and stream live multi-bitrate video over HTTP to Flash and iOS", which confirmed that I seem to be doing everything right, but I'm still getting the "The operation could not be completed" error message on both iPad and iPhone.
Grasping at straws, I'm wondering if it could have something to do with some of the "hacks" I was asked to make in the other tutorials, (which, oddly enough, weren't mentioned in the tutorial mentioned above). Specifically:
     • Edit FMLE config file on the Mac I'm encoding the live video on (change <streamsynchronization> from false to true)
     • Delete/Rename the "manifest.xml" file in applications/livepkgr/events/_definst_/liveevent directory
     • Edit "event.xml" in applications/livepkgr/events/_definst_/liveevent (change <segmentduration> from 40,000 to 16,000)
However, I've tried running this with the above hacks as well as in their non-hacked state and am still not seeing success.
Please advise. Thanks!

Tutorials: on-demand and live streaming

This question was posted in response to the following article: http://help.adobe.com/en_US/flashmediaserver/amazonec2/WS6fc2df2b6d2ce24359910e2812c396a83 eb-7ff8.2.html

I followed the instructions to "Live Streaming with DVR", but it's not quite working for me. I'm able to push a live stream to the EC2, and view it through the Flash Media Playback Setup page under the "Live" option in the Advanced tab. However, I am not able to enable the DVR functions. I have added the dvrcast_origin folder to /mnt/applications, as instructed, but I have no "streams" folder in dvrcast_origin, nor any video from the stream saved to the EC2 that I can find. Any suggestions?

Live stream problem with FMS 4.5 + FMLE

Hi,
I've got a live stream (and DVR) setup using FMS 4.5 and FMLE.
The hardware for the FMS server we use is 2x Xeon E5645 2.4GHz, 32GB RAM, OCZ RevoDrive R3 X2 PCI-e SSD. Installed OS is CentOS 5.8.
We have 6 workstation PCs, each equiped with 4 BlackMagic Intensity PRO capture cards and FMLE 3.2. Using these PCs we stream Live video to FMS server.
Video stream is grabbed from HDMI cable, to BlackMagic Cards, which are encoding by FMLE using H.264 format, 700kbps bitrate per stream.
Video stream is published to server through RTMP stream, which is later saved for DVR in RAW format. We only keep 3 days of recording and delete the old ones.
Server and Encoder PCs are in the same network, connected by gigabit managed switch.
The problem I'm having is that after 10-15 hours FMLE starts to drop frames, because video buffer is increased. What I observed is that this happens immediately when Server CPU load increases above 60%.
Based on the above observation I decreased the number of channels streamed by the server to 10, which reduced CPU load. But the problem still persists.
Whenever I restart FMS and delete all DVR data, the CPU load (when streaming 10 live channels) is only 1%, but after 2 days CPU load increases to 50-60%.
Whenever I restart FMS and don't delete DVR data, the CPU load is 5-10%, and after 2 days it still increases to 60-70%.
Another thing I observed is that there is only single fmscore process running, but it has lots of threads which are switched on and off in split seconds. These threads are launched on different CPU cores, but at any given point in time the distribution of the load isn't equal among CPU cores. This leads certain CPU cores being loaded by more than 60% and frame drops start to occur.
For the moment there are just 10 users watching this service, so I don't think this load accounts for the problem.
Has anybody had similar problem, or know how can I optimize or finetune the system to run without problem? I would appreciate any suggestions.
Another thing I noted through last couple of days:
When I was restarting FMS the CPU load was reduced to 30%, but after 1 week past when I restart it CPU load only goes down to 75%. Everything is the same, nothing has been changed and there is no disk IO issues involved.
P.S. I've modified application.xml using these values:
<Scope>vhost</Scope>
<Distribute numprocs="5">app</Distribute>
<LifeTime>
<RollOver></RollOver>
<MaxCores></MaxCores>
</LifeTime>

Hi
How many channels are you publishing?
If there are too many channels, it is recommended to have one FMSCore process start for each of them. To do so, you will have to change the scope to app.
---snippet---
<Application>
<Process>
<Scope>app</Scope>
<Distribute numprocs="3">inst</Distribute>
</Process>
</Application>
Also, to delete older content, you will have to enable disk management. Refer http://help.adobe.com/en_US/flashmediaserver/devguide/WSeb6b7485f9649bf23d103e5512e08f3a33 8-8000.html#WSec225f632fa00875-23954b6f1300b641158-8000 for more info.

Can storing a live stream using actionscript fail by the cache filling up with overhead?

Hi,
Lately we have been seeing a problem with the archives of live streams we create using FMS. We use FMS for live streaming and concurrently store the stream in a file using ActionScript. We use the following code to record:
var s2 = Stream.get('mp4:' + mp4name);
application.publishedStreamMP4= s2;
application.publishedStreamMP4.record();
application.publishedStreamMP4.play(application.publishedStream.name,-1,-1);
(some lines have been removed that are used for logging, etc).
Sometimes some of these functions fail and return false. In these cases FMS's core log shows that the cache is full:
2013-06-11 11:45:55        13863   (w)2611372      The FLV segment cache is full. -
In investigating this issue I have not yet been able to recreate this exact situation. By lowering the cache to 1MB I have however been able to create a situation where storing a stream can stop because the cache is full. The situation occurs as follows:
* The server is restarted, the cache is empty.
* A live stream is started, which is also recorded.
* Via the Administration API the cache values <bytes> and <bytes_inuse> show to be exactly the same as the <overhead> of the object that relates to the file being saved. The <bytes> and <bytes_inuse> values of the object are 0.
* This continues in the same way untill the cache is full.
* When the limit of the cache is reached the message
2013-06-11 12:07:35        13863   (w)2611372      The FLV segment cache is full. -
is shown in the core log and storing of the file stops. The instance log also show status changes:
2013-06-11 12:07:35        13863   (s)2641173      MP4 recording status for livestream.mp4: Code: NetStream.Record.NoAccess Level: status Details:         -
2013-06-11 12:07:35        13863   (s)2641173      MP4 recording status for livestream.mp4: Code: NetStream.Record.Stop Level: status Details:     -
In the filesystem I can confirm that the last change of the file is on this moment (in this case 12:07). The live stream continues without problems.
I have reproduced this several times. Though I can understand that caches can fill up and this can cause trouble I feel like this situation is a bug in FMS. The cache fills up with overhead, which is apparently reserved untill writing the file ends.
I hope someone here can help out. Has anyone seen a situation like this and is there any remedy for it? Or even a workaround where this overhead in the cache can be released so the cache does not fill up?
We use FMS version 4.5.1.

You can use an XML socket, but the FMS application will need to initiate the connection, as FMS has no support for listening for anything other than RTMP and HTTP requests.
Stream switching can happen on the FMS side. In your FMS application, you'll create a server side stream, and use the Stream.play method for playing other sources (live streams or recorded flv/h.264 files) over that stream. Your subscribers will connect to the server side stream
See the FMS docs for the Stream class and the XMLSocket class.

Creating a custom player for live streaming video

I have live streaming video set up where I use the Flash Media Encoder to send the live stream to a Flash Media Server. Then, the Flash Media server packages this stream, and sends it to whatever websites requests it via the url. I know how to create a Flash move or even asc file, and then have Flash generate the html for that saved movie so that I can embed it in a web page and play it. But in the case of live streaming video, there is no pre made asc file or movie to reference. So I need some help about what I need to do to play live streaming video in a flash player embedded in a webpage, that will also have some custom action script for controlling playback and other things.

About a half-hour after making the changes I outlined above, and long after I closed the active Safari window, noticed that my MBP was uncharacteristically hot. Extremely hot!
Opened Activity Monitor and saw that Flash Player was still running (?) and using a tremendous amount of system resources. I then quit Safari altogether. Within moments, the heat began to subside.
May be something you want to keep an eye on...

Windows Media player - live stream

I have Mac 10.4.5 and am having trouble viewing live feed with Windows Media Player. WMP seems to work with saved video streams but not live. Any suggestions?
Thanks.

I'm wondering if you received a reply. Neither the Windows Media Player in Internet Explorer nor Safari will give me a live feed for more than 30 seconds to 1 minute and will then freeze. "Refreshing" the page doesn't provide a "live" response.

Hi ReChan,
-IMAQ Snap Configures, starts, acquires, and unconfigures a snap acquisition.
-For IMAQ Grab you're configuring initally. So, whenever you click boolean-imaq snap captures image and unconfigures the IMAQ session.
-When you try to grab again, it will throw an error because IMAQ session isn't configured.
-The mechanical action of boolean you kept as switch when pressed-it'll stay high-which results asking user for saving an image. instead i changed it to latch.
Thanks

Live streaming stops automatically after 15 minutes

I am using flash media server 3 and flash media encoder 2.5.
From media encoder I am sending data to media server and then in
browser I am running flex application (version 3) to view the live
stream. I am not saving it in flv file. After 15 mintues live
streaming stops automatically. I have tested all events related to
it..but none of them executes..Flex3 application is just working as
a client.
Portion of code:
nc.connect ("rtmp://localhost/myLiveApp/instance1/");
vid.attachNetStream (ns);
ns.play("flv:mylivestream");

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?

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....

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.
