Opencast live schedule module

[Kristof Keppens]

Hi List,

I’m currently experimenting with the built in live schedule module, but it’s not really working as expected. I followed the documentation ( running opencast 8.x ), configured everything as expected. I see the live schedule service starting up in the logs, without errors. I’m using the default workflow, but when I’m scheduling an event, with the live schedule enabled, nothing happens regarding live streaming.

The event gets recorded, and the capture agent is streaming but in the media module nothing is visible. Are there any changes to this module that would require extra configuration, or is anyone using this and can provide us with some extra guidelines how to set this up ?

Hi Kristof,

Did you have this working previously?  Or is this an entirely new setup?

Hi Greg,

This is a completely new setup. We are currently investigating alternatives for our current live stream portal, and since almost all livestreams are lecture captures ( the remainder are public live streams that can go to youtube ) we thought that opencast would be a great match since this functionality is built in. But struggling to get it working as expected. It seems that the live-schedule-impl isn’t reacting on new schedules that have the publishLive: True setting.

Hi Kristof,

Fair enough.  I'm not much use here since i don't have any live streaming set up, but it sounds like Koln is having issues, and Osnabruck will be looking into it.  Hopefully this can surface any issues you're running into and get them fixed.

Hi Kristof,

    What do you see in the logs? Do you see the message "Creating live media package..."? Or any errors?

    Thanks,

Hi,

Live streaming is working again in Cologne with Extron SMP (LTI and ILIAS OC-Plugin) , but unfortunately not the processing of the recorded data.

We have to check why this problem exists, because with OC 7 we do not have this problem at all.

Hi,

It seems that everything is working fine now including the processing of the recorded data using the workflow.

Problems seem to exist when the duration of the live event is very short (< 5min).

But when you upload/re-ingest the recorded material from the Extron the workflow runs without any error.

@ Kristof: If you are still interested I can send you our configuration for live streaming tomorrow. But keep in mind, that we are using HLS streaming for all our deliveries including the live streaming.

Hi Kristof,

i can test the streaming tomorrow with OC8 and our setup.

As we will switch to OC8 in the next semester we are very interested, how it works. ;)

In between can you give us your logs, and the configuration?

Hi Kristof,

here the configuration, we use for live streaming in OC 8.

We use the Confidence Encoder part of the Extrons

live.streamingUrl=https://<wowza-server>/extron
live.resolution=1280x720
live.streamName=#{caName}/playlist.m3u8
live.mimeType=application/x-mpegURL
live.targetFlavors=presenter/delivery
live.distributionService=download
live.publishStreaming=presenter/delivery:1280x720

Hi Rute,

No errors in the logs, I do see the messages from the service starting up, but then when creating a new scheduled live event nothing in the logs relating the live schedule.

Are you using it with opencast 8.x ?

Hi Kristof, 

Did you manage to find the solution? We have a what seems to be similar problem.
