How to record live streams (HTTPLiveStreamRecord)

[rrlanham]

Change the /conf/[app-name]/Application.xml /StreamType to "live-record".

Richard, thanks for your promptly answer, but I'm already using <StreamType>liverepeater-origin</StreamType> and <StreamType>liverepeater-edgeN</StreamType>. In this case, how can I use it? Thanks.

[rrlanham]

In that case, change the origin Application.xml /StreamType to "liverepeater-origin-record"

Hi, Sorry I'm new here and have some question about a such feature.
As far as I can see, with this module we can see a live and record it on demand.

But is there a way to do the same thing during live publication ?

So, for instance, I am a live publisher.
I set the rtmp server address and the stream.
I begin to publish live.
And after a while, I want to record a part of my own live.

How can do that ?

Thanks.

Yes, that is how this package works. Get it from here:

Hi,

I ve setup a site that allow live recording with a flash movie/wowza server. Some users have serious issue with audio/video in the produced flv , here is an example : http://accessdev.s3.amazonaws.com/temp/723.flv

Do u think that s it is only a matter of bandwitdh ?

[rrlanham]

Bad recording in this scenario is often caused by poor upstream bandwidth where the user is publishing from. One way to mitigate in the Flash application that is publishing is use very high buffer setting in the netstream object, it can help in some border line cases, might not help in very poor conditions with longer videos very much.

Use Flash 11 and h.264, which has better compression, might help some. There is guidance here on implementing that in Flash:

That's great.
But when I looked at the "client\livestreamrecord.html" example, I see only play button for an already diffused stream live.
Does it mean that this module can record its own diffused live but not with this example ?

I try to load on Wowza Media Server 3.0.5 build1220 the plugin ModuleLiveStreamRecord and i get this error

loadModFunctions[haivision/_definst_]: Module class not found or could not be loaded. Check [install-dir]/conf/haivision/Application.xml to be sure all Modules/Module/Class paths are correct: name:ModuleLiveStreamRecord class:com.wowza.wms.plugin.livestreamrecord.Module LiveStreamRecord

Do you think i need recompile the plugin

Look like version LiveStreamRecord_3.0.zip as been updated

[rrlanham]

This might be a typo in the Application.xml /Module.

Or you did not restart Wowza after adding a jar file.

Or, if you are building a module in the IDE you might be compiling to an old Wowza location. To see if that is the case, take a look at the /lib folder of recent Wowza install, see if the .jar file is being compiled there.

Hi

What would be causing corrupted recorded files?

I'm recording several live streams from different applications.
Each application contains two live streams; high and low.
I'm starting and stopping to record both streams (high and low) at the same time.
I have 10 different applications with the same configuration.
Some times I start and stop recording 4 to 5 applications at the same time.

My question is;

APP1 records stream 1h.sdp and stream 1l.sdp
APP2 records stream 2h.sdp and stream 2l.sdp
APP1 and APP2 start to record at 15:00 (4 streams at the same time)
APP1 and APP2 stop recording at 16:00 (4 streams at the same time)
2h.sdp.mp4 and 2l.sdp.mp4 files are OK
but
1h.sdp.mp4 and 2l.sdp.mp4 files are not.
Both files plays 50 seconds on VLC or any other player then gets stuck, if I scroll forward, it continues to play (some players without audio) VLC with audio.
When I use VOD application on WOWZA to stream the same files and play them with the silver light player in the example folder of wowza, they play smoothly 50 secs. then picture goes fast forward and backward, stucks but continues to play audio smoothly then al of a sudden continues to play again as if there was no problem.
I can also jump further and back after it gets stuck or even before 50 secs. Meaning I start to play from the beginning and after 20 secs I can jump to 20 min or more.

On the other hand, I upload the same files to cloud storage, and when I try to play from there on any player, they got stuck at 50. sec and that's it.
here is the example http request I use;

Action Type: startRecording
http://localhost:8086/livestreamreco...h.mp4&format=2
http://localhost:8086/livestreamreco...w.mp4&format=2

Action Type: stopRecording
http://localhost:8086/livestreamreco...h.mp4&format=2
http://localhost:8086/livestreamreco...w.mp4&format=2

This insidence happens randomly not everytime spesific application.
thanks

Metin,

Maybe your disk can't keep up in some cases. You should have 2 or 3 or more disks in RAID 0 array.

Network interruption can also cause corrupt files.

Hi Richard,

Thanks for the info;
I'm using raid 5 configuration IBM storage. 7.5TB in total and it's local drive on WOWZA server,
It's true other servers are also writing on the same storage via net share.
The network is indeed 1GB
How many live streams can wowza record simultaneously?
This server is not live streaming to any client, I use it only for recording.
I do not start recording the same stream with different file names.
I record different streams from different applications at the same time.
Here is my Common Application.xml
What would you suggest to modify? (This server is not streaming to any client, only for recording the live input streams)
Thanks
Metin

I'm not sure if RAID 5 helps. I think that is more for redundancy, so it might not help at all. RAID 0 is the performance configuration that you want for recording.

I don't know if I change the configuration now, but thanks.
Any suggestions for the application.xml to improve the performance?

Hello! Is it possible to record all the streams produced in a key-alligned group by transcoder module? I can do it with the original source stream but I don't know how to do it with the transcoded sub-streams :-(. Thank you!

[randall]

Setting your StreamType to "live-record" in your Application.xml should get them all.

Cool, now the main stream and all the transcoded streams are being recorded.

I stop the recording via HTTP.
The main stream recording stops
BUT
the transcoded streams recording continues or Wowza is keeping lock on them, they grow in size and there are still being produced the .tmp files.

What is wrong? Are there any limitations on versioning function?

THNX!

[rrlanham]

Sounds like you are using the LiveStreamRecord addon also. You don't need to use that if you are using StreamType "live-record"

Note, however, that I have had problems with StreamType "live-record" and the Wowza Transcoder, because using that method the incoming stream and all the encodes are recorded, which can be too much for a single disk. The solution is RAID 0 or 1+0 disk array.

I need to gain a higher level of control over the recording process than simply to start it with the application and stop it when the application stops. I thought that it could be achieved with LiveStreamRecord module. If I stop using it and just change the type to "live-record", is it possible? Without "live-record" there is no recording of substreams and without LiveStreamRecord there is no control via HTTP of the recording process. Am I right?
I saw an ideal combination in LiveStreamRecord module in cooperation with transcoding module.

THNX!

The speed of the storage should not be an issue here.
