Question / Help OBS to Kaltura : Can it work?

[Bcost]

Hey everyone, I work for an opensource Social Archive and we have implemented http://corp.kaltura.com/ as our video solution. I am experimenting with Livestreaming currently and have had success broadcasting with Adobe Flash live Media Encoder, but as we are an opensource site, recommending users to a non-OS broadcast platform is less than ideal. I have been playing around with OBS and think it''s very powerful for event broadcasts and would be perfect for what we're looking for. However thus far I am unable to get it to successfully broadcast to our Kaltura Management Console (our media entry archive)

I was wondering if anyone has any experience broadcasting to Kaltura, or what might be involved in order to make this a possibility.

You should be able to punch in the same values you used in FMLE to OBS as a Custom streaming service in Broadcast Settings

Hey Warchamp, I appreciate the reponse. I'm working on figuring out what each value from Kaltura translates to. I'll list The values/information I have access to in the Kaltura Console. I was hoping you could tell me what each field translates to in OBS. I'll include if i used each field in Adobe flash live Media Encoder.

Entry ID :the Database ID for the media entry, never used in Adobe
Primary URL : assuming this is the FMS URL
Backup URL : never used
Stream name : in Adobe I enter this into the field below FMS URL titled "Stream", Not sure where this belongs in OBS
Username: Not needed in adobe
Password: also never came up in adobe
Encoder IP: never came up

I guess the fields I'm struggling with are FMS URL, Path/Stream Key, and Dashboard Link.

hope any of this helps.

thanks

Try Primary URL as FMS URL and Stream Name as the Play Path/Stream Key.

Hello!

Sorry about the necro, but I figured this was a apropriate place to ask.

I am having some issues connecting to a Kaltura Live Stream via the Akamai Content Delivery system.

Normally when using Adobe FME I enter a FMS URL, Backup URL, Stream name. When I Connect I get asked for a username and password for both servers. This works perfectly.
However, for the Open Broadcast Software there is nowhere to input backup URL or authentication settings under Settings->Broadcast Settings: Custom.
The log gives me a rtmp server sent error on librtmp, saying it could not access the channel or stream key (See error spoiler bellow). Some sort of authentication issue perhaps?

Does Kaltura give you a stream key or play path to use? Can you chack your settings somewhere for it?

You have to give OBS a Stream Key/play path, unless Kaltura relies on FMS authentication, which OBS unfortunately does not support...

Yep, it gives me a Stream Key.

What I did was to put the Stream Keyit in the "Play Path/Stream Key" field in OBS and put Primary URL in the "Server" field. But no luck, same error. I have also tried putting backup URL in the "Server" field.

And yes. Kaltura relies on FMS authentication. :(
