SRT Relay 1-to-Many

Mark P. 2020-06-02 16:54:50 UTC in Nimble Streamer


I have the ability to send an SRT stream to my Nimble Streamer instance for ingestion and redistribution.

I want to accomplish the following to start with:

Have Nimble Streamer ingest the SRT stream and rebroadcast that stream to SLDP players at some URL, i.e. 1-to-many SRT relay. However, from reading the description for Nimble Streamer it says "Supports SRT ingest and transmuxing/distributing in RTMP/HLS/DASH"

I don't want RTMP, HLS or DASH. I want the SRT stream coming into Nimble Streamer to be relayed by Nimble Streamer to SLDP players.

Is there a step-by-step guide for doing this?

I also want to find out how many SRT streams can Nimble Streamer ingest and relay at the same time using some example AWS EC2 instance. I'm looking for benchmarks on how well it scales on a single server and recommended EC2 instance for best performance/lowest latency. I am thinking of M5 or C5 instances with ENI support, but I have no idea really what the best instance type would be. Any tips would be appreciated.

Hi Mark,

You should take a look at this article on Haivision blog
It has both SRT and SLDP delivery like you ask about.

If you have any specific setup questions please contact our helpdesk

Mark, as for benchmarks, we haven't performed them but transmuxing is a very resource-cheap operation. You can try it with the cheapest instances first to see how they work for you.

Thank you.

I have the SRT source already (OBS) and I think I'd like to try producing SLDP out on the server so I can terminate it using it CloudFront, following your other article about the subject.

Where I'm stuck in my evaluation of Nimble Streamer (even before I start) is whether or not I can actually build a service around it with users, and for that I need a clear idea of how to associate SRT streams from publishers with user accounts that I can control and host in my infrastructure. Happy to pay for WMSPanel (for sure!) but I need to build the service in a way that is independent from any external tool (except for analytics) So I need to learn how to configure Nimble Streamer directly. I think of WMSPanel more for analytics and monitoring, which I'm very happy to pay for.

I created another thread asking about how to authenticate SRT streams (associate stream with user) and I hope to get some clarity from you on that, too.

Thank you. I'm very excited to try SRT/SLDP but I need to know it could work for me in terms of my business requirements.

Thank you.

We've already reviewed your questions and answered here:
We'll introduce users authentication as part of new feature set - so stay tuned for updates.

Ok. Looking forward to it.

Will check your release announcement periodically starting next week.
