#OBS now supports WebRTC simulcast support.

I understand it'd be a HUGE undertaking, but what kind of time/money would it take to write a library to handle this to get it into #Owncast and #Peertube ?

Right now the single most expensive thing is transcoding. If we can support #Webrtc #Simulcast that moves to end users and the server can is just a pass through enabling anyone to run live streams through their Peertube or someone to run massively more Owncast streams at once.

So I'm being serious. What would this take?

@ozoned I don't think it's something you can improvise or add only as an afterthought to an existing backend: WebRTC is tricky, especially on the server side, and simulcast is only part of the equation. I did my tiny online concert last summer using OBS and WebRTC (no simulcast support in OBS back then) since I didn't have an Owncast instance I could use, so I just used my own WebRTC SFU (Janus) for the purpose. There are other servers too that handle WebRTC as a first class citizen

@lminiero@fosstodon.org reading through Janus docs. You built this?

I've been talking with me community and I think we're going to test this out, maybe live. If you're every interested in talking about this, let me know.

I run a podcast called fireside Fedi as well. We can do an interview of you'd like. @firesidefedi@tubefree.org if you care to check it out.

But also is you'd like to help or watch or anything.

Actually I'm also liking to run another podcast where I talk to a developer while attempting to install their application. It's called Works On My Machine LIVE.

@ozoned @firesidefedi sure, I'd be happy to talk about it if you want! The podcast idea is cool too: I've done a lot of presentations on my work, but only a couple of podcasts, which is a pity as I find the conversation approach more interesting.

FYI, there's a lot of info material on WHIP/WHEP on my company blog too. The latest was on the libraries, with many examples:

It would be interesting to see how easy/hard the whole thing is for who's starting from scratch!

We've talked many times about WHIP and WHEP on this blog post. Since before WHIP was even a thing on the IETF's radar, we prototyped it with CoSMo, as it seemed like a great first step towards my dream (and Ph.D thesis topic) of having a pure WebRTC based broadcasting solution. We then covered it
