HLS Serverless Streaming

[Christian G]

Hello,

is there somone using serverless HLS Streaming allready in production?
I am searching for an example configuration.

If somone could send me one or give me a hind where it is documented,

that would be very nice.

The only thing i could find is on this video.

Thanks

Hi Christian,

this is very late and I hope you already found a solution.

We use it, but our setup is somewhat unconventional. You can find most of our configuration here: https://zivgitlab.uni-muenster.de/educast-nrw/opencast/workflows/-/tree/educast/12

Thanks Matthias,

if somone else is searching it for the future. I found the examples in the 10.x branch.
https://github.com/opencast/opencast/blob/r/10.x/etc/encoding/HLS-streaming-movies.properties

and

https://github.com/opencast/opencast/blob/r/10.x/etc/workflows

The Problem in my case was to find the right pallea player version which works with hls on most of the different devices.
So i stopped implementing this, and we will wait for the new Pallea player in this case.

Hi Christian,

I’m curious how the Paella player has been failing with the HLS serverless streaming in your tests?

Our site uses server-less HLS with the Opencast encode (our HLS-streaming-movies.properties are a little different than the 10x version) and the Paella player. I cannot recall if the Paella player required modifications to support it.  We are currently using Paella 6.5 with local customizations.

As far as browser support, I notice that the native Safari HLS player has buffering and occasional freeze up issues when playing our HLS serverless manifests. Chrome and Firefox, and non-native HLS browsers, do not have problems. The Paella player provides non-native HLS browsers, like Chrome and Firefox, with a well supported and strong error handling HLS.js library. Our site is considering modifying the Paella player to force Safari to also use the HLS.js library, in order to get consistent HLS performance across all browsers.

Best of luck!

Regards,

Karen
