Nice job! This is much better then the status quo today. Even if things are E2E encrypted it is so wasteful that 'HTTP Tunnels' route through jump servers. Cool thing about WebRTC is you can put this in a lot more places if you wa

Thank you so much for using it. I feel so honored(and surprised) that people use it. I totally stumbled into a successful project. If I ever can be helpful with your projects reach out!

What makes something a 'blessed way'? Are you looking for community support, large corporate users etc..? Not being snarky, curious about how people see the space. Lots of implementations exist and I have used most of them for dif

libdatachannel[0] is exciting me the most for 'low footprint'. str0m[1] is especially exciting, but you have to be in a device/ecosystem that allows rust. > only if you use the same kind of software and codecs With WebRTC

The book 'Show Stopper!: The Breakneck Race to Create Windows NT and the Next Generation at Microsoft' is a really great read on Dave Cutler. I would love more 'tech origin stories'. Next I am planning to read 'Soul

Why do you think this was a joke? I have have been trying my best to make WebRTC more accessible [0] [1]. It's powerful, but the complexity makes it challenging. [0] https://github.com/pion [1] https://webrt

Depends what codec! For 1280x720 with a VMAF score of 90 this is the numbers I use. * H264 - 1.25Mbps * VP8 - 1.00Mbps * VP9 - 700kbps * AV1 - 550kbps

What did you find difficult about WebRTC? What could have been better/easier?

Cloudflare has been doing some amazing stuff with live video. I am so glad they did WHIP/WHEP[0] support. That lets me push video from my browser and pull via GStreamer. Or I can push via OBS and watch in browser with 300ms of latency!

Go isn't the problem. The issues I have seen is that you are I/O bound by the kernel. One company did Pion WebRTC + https://www.dpdk.org/ and is now doing 4x throughput. They tried switching to Rust (and still doi

Really great writeup. Stuff like this dispels the FUD that 'You can not scale WebRTC'. It for sure is harder to scale then static/loss-less content like HTTP. But I have never found it intrinsically harder then other media. I

What protocols/networks do you consider P2P? Every P2P technology I have used requires some bootstrapping. I have done WebRTC with zero signaling, but browser only one side[0]. I wish the w3c/ietf would care, but that’s the issue

WebRTC will live on. I think it will continue to grow from grassroots efforts. WebRTC has P2P and it also doesn't require the user to have any knowledge of Video/Networking. The alternatives to it are more geared at 'video de

Works well! Lots of developers/companies use WebRTC with NAT Traversal. You can also use it in a client/server setup. Check out 'WebRTC SFU' I wrote a little bit about the different topologies in [0] [0] https:/&#x

Most of the work happened in the libdatachannel! You can check out my PR here[0] OBS already has everything around AV1, so I just needed to handle packetization :) The `is_av1` is already going away. Bad code on my part <_< [1] [0] h

The optimization for size is pretty hard (for me at least). Lots of cool stuff you can do. But if you are on a time crunch/trying to go to production it doesn’t happen. These days I just default to ‘thin’ implementations like mbedtls w

I am adding WebRTC sources to OBS. Does that makes things easier? Then you can push+pull into Broadcast Box and use OBS on both sides!

There is an Elixir version of WebRTC available. It is still early days, but your feedback/asks would be monumental in making it better! https://github.com/elixir-webrtc

You could totally do it, but if it doesn’t sound interesting I get it :) WebRTC is made up of composable parts which I really appreciate. Makes it seem more complicated though.

> i m not sure you can control the exact video resolution/bitrate You are right WebRTC doesn't give you control of this. It is on purpose though. If a webpage could push more bitrate then the link supported it would cause cong

Woah! This is very cool I don't think I have seen it before. This will be really useful to establish a connection in adverse situations. Try all the different ways until you can get through :)

What about WebRTC do you find hard? I can connect two browsers and start a video call in ~50 lines of JS. As you need more features/knobs it does get harder. I think that is just a reflection of how difficult the problem is of real-tim
