what I'm obsessed with is getting us to a world where video (live and on demand) works like podcasting. lots of options for creators and consumers, made possible by agreement on something like an API/protocol. how does Janus fit into the world of #owncast and #peertube? I don't know of a player that handles both of those. I think that's how we displace #twitch and #YouTube.

@wjmaggos @ozoned@btfree.social @ozoned@tubefree.org I'm not familiar enough with how Owncast and Peertube work, but the main challenge is the different technologies they rely on: traditional broadcasting typically uses RTMP for ingestion, and HLS/DASH (HTTP chunking) for distribution. WebRTC is quite different from both, so you have two choices:

1. switch to WebRTC for both (what WHIP/WHEP are about)
2. add WebRTC to the picture, but keep the other too (which means transcoding and tech adaptation, though)

@wjmaggos @ozoned@btfree.social @ozoned@tubefree.org Janus can help with both, but can only do 1. on its own, for 2. you need to work on some integrations as we don't do RTMP/HLS/DASH ourselves, so you use RTP as a bridging technology via Janus.

Here's some material that may be of interest, like the talk I did on social audio (including podcasts via WebRTC)

Node.js WHIP/WHEP server libraries

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
