I have a beginner question - Can WebRTC be used as an alternative to sending base64-encoded images to a backend server for image processing? Is this approach recommended?

WebRTC excels at sub-second latency peer to peer, so you can do near-realtime video, so anywhere that is useful. Say you wanted to do a virtual portal installation connecting views from two different cities with live audio, you could have ffmpeg feed off a professional cinema or DSLR camera device with a clean audio feed and stream that over WebRTC into a webpage-based live viewer. Or say you wanna do a webpage that…
The irony is that you don't _actually_ need WebRTC to get subsecond latency; you can fairly reliably get ~100–200ms (plus network latency) with a completely normal TCP stream.[1] But since browsers have effectively standardized on HLS, whose design is completely antithetical to low-latency (you _can_ do low-latency HLS, but only with heroic efforts), low-latency streaming video has never really been part of their bre…

Quick! Quick! I need to find something bad about it... wait... AH!
Does it compile with the latest libressl? Hopefully not (like python _ssl.c) and I can start talking bad about it.
;P
Ofc, that was irony.
We all know the main issue with webRTC is not its implementations, but webRTC itlself.
All that said, it is exactly at this very time twitch.tv chose to break ffmpeg HLS (its current beta HLS streams are completely breaking ffmpeg HLS support...).

Not sure I follow your maths there. If we assumed an average of 6Mb per stream that's 3000 streams, practically speaking a little lower. It's all relative I guess but it's not that high.

Does multicast actually work from a home network to another set of homes over the internet? I thought this traffic would just get dropped by one of the hops along the way if you tried it. https://networkengineering.stackexchange.com/questions/47994...
A commit that was "co-authored-by" 6+ people and has three thousand lines of code: this is a total wreck of a development workflow. This feature should have been implemented with a series of about 20 patches. Awful.
You are being downvoted, but you are entirely correct. This is also explicitly not allowed in FFmpeg, but this was pushed after many months, with no heads up on the list, no final review sign off, and with some developers expressing (and continuing to express) reservations about its quality on the list and IRC.

Wow, you are not wrong. I just asked Gemini "how can I use ffmpeg to apply a lower third image to a video?" and it gave a very detailed explanation of using an overlay filter. Have not tested its answer yet but on its face it looks legit.
It's amazing --- I cut my teeth in software engineering with ffmpeg-related work 15 years ago, LLMs generating CLI commands with filters etc. is right up there with "bash scripts" as things LLMs turned from "theoratically possible, but no thanks unless you're paying me" into fun, easy, and regular. Yesterday I asked it for a command to take a 14 minute video, play the first 10 seconds in realtime, and rest at 10x spe…

Where's the best place that people are talking about WebRTC then? Hacker News doesn't have rooms by topic does it?
Broadcast Box has a discord https://discord.gg/An5jjhNUE3 You could also join the Pion one https://pion.ly/discord Other place is video-dev Slack https://www.video-dev.org/ X also has a great community of hackers!
Too bad nobody is using open forums (e.g. Discourse, Matrix, Mastodon).

"Have not tested its answer yet but on its face it looks legit." That's LLMs for you
