Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Is Something Bugging You?
- Dropbox [3] uses a similar approach but they talk about it a bit more abstractly.
Sans-IO is more documented in Python [4], but str0m [5] and quinn-proto [6] are the best examples in Rust I’m aware of. Note that sans-IO is orthogonal to deterministic test frameworks, but it composes well with them.
With the disclaimer that my opinions are mine and mine alone, and don’t reflect the company I work at —— I do work at a rust shop that has utilized these techniques on some projects.
TigerBeetle is an amazing example and I’ve looked at it before! They are really the best example of this approach outside of FoundationDB I think.

Pure C WebRTC
I am really excited about https://github.com/sepfy/libpeer. It has examples ready for ESP32 etc....
When working on KVS I wasn't familiar with the embedded space at all. I saw 'heavyweight' embedded where you were running on Linux. Then you had RTOS/No OS at all. I wasn't prepared for these devices at all. If we can make WebRTC work in the embedded space I think it will really accelerate what developers are able to build!
Remotely driven cars, security cameras, robots in hospitals that bring iPads to infectious patients etc... Creative people are building amazing things. The WebRTC/video space needs to work harder and support them :)
-----
I love how diverse the WebRTC space is now. Outside of this implementation you have plenty of other options!

This is really interesting! Any latency benchmarks comparing it to gstreamer UDP, P2P primarily?

OBS Studio 30.0
This release includes WebRTC support. I would really appreciate if people could try it! I have so many things I want to improve with broadcasting.
——
* Serverless Streaming - WebRTC is P2P so you can video right into your browser. You don’t have to stand up a server anymore to stream for a small audience.
* Sub-Second Latency - Create content and interact with viewers instantly. There is something magical about having a real conversation with your viewers.
* Multitrack Input - Upload your transcodes instead of generating then server side. Give viewers multiple video tracks to see action from all sides.
* Mobility - WebRTC lets you switch networks at any time. Go from WiFi -> Mobile with zero interruptions.
* E2E Authentication - WebRTC lets you add authentication on the sender and receiver. Broadcasters could sign their video streams so viewers can be sure it wasn’t modified.
Try it out with Broadcast Box. A reference server implementation. https://github.com/glimesh/broadcast-box

Show HN: AV1 Broadcasting from OBS
This is a PR (with builds) to add AV1 support to the WebRTC output from OBS.
We also have been working on a reference server implementation with https://github.com/Glimesh/broadcast-box/ to make it easy to self host.
-
Show HN: OBS with Simulcast Support
Simulcast builds of OBS are available. Simulcast is when a client generates multiple encodes of a video. Testers and feedback would be greatly appreciated!
Design Discussion: https://github.com/obsproject/rfcs/pull/55
Use it against your favorite WHIP ingest. If you don't have one check out https://github.com/glimesh/broadcast-box. It is a reference implementation of a WHIP/WHEP server.
I hope/believe the impact of this will be much greater then WebRTC. This could benefit all broadcast workflows.
* Higher Quality Videos - Decoding and re-encoding causes quality loss. Generating all the renditions from the source video is going to be a big improvement for viewers.
* Lower Latency - Removing the additional encoding/decoding allows video to be delivered faster.
* Reduce complexity - With Simulcast setting up a streaming server becomes dramatically easier. It is much easier for an individual to afford and manage a single broadcast server. RTMP -> Transcode -> HLS gets complicated and expensive quickly.

OBS merges WebRTC support
One of the devs commented on HN that you can use Broadcast Box handle the initial connection. That's open source so you can self-host that too

OBS Merges WebRTC Support
Try it out today with Broadcast Box. A reference server implementation. https://github.com/glimesh/broadcast-box. The PR to add WebRTC to OBS https://github.com/obsproject/obs-studio/pull/7926
I don't have an idea on how to do cascading OBS instances. I should write some software to make this easy though. I want to make 'self hosting' as easy as possible. I think https://github.com/glimesh/broadcast-box will fill that gap for now.
For my own usage I run WebRTC servers and have them 'replicate' the video traffic. LiveKit did a write up on this with some good graphics https://blog.livekit.io/scaling-webrtc-with-distributed-mesh...

WebRTC support being added to FFmpeg
I am really excited for this PR to land. Being able to use WebRTC for Broadcast and Playback is going to be huge.
Instead of doing fixed interval keyframe we can use receiver feedback (Massive reduction in bandwidth)
Instead of server side generated transcodes we can use Simulcast. Will be better quality AND massively reduced server load.
If anyone wants to use with Pion check out https://github.com/Glimesh/broadcast-box
Then run `ffmpeg -re -f lavfi -i testsrc=s=1280x720:r=30 -f lavfi -i sine=f=440:b=4 -vcodec libx264 -pix_fmt yuv420p -profile:v baseline -r 25 -g 50 -acodec libopus -ar 48000 -ac 2 -f rtc -authorization "STREAM_NAME" "http://localhost:8080/whip"
