Stumbling over Microsoft’s Video Conferencing Dataset (VCD) I asked Claude to take on a video codec engineer’s favorite hot take: compare video codecs. It did a fairly good writeup using the tooling provided by libWebRTC. One of the most surprising results was that background blur makes H.264 a lot more effective. Other than that, the […]
Vector Vibing to speed up Opus encode by 20%
tl;dr: Opus encoding just got 20% faster on desktop Chromium by turning on AVX2 vectorization in libopus. Vectorization means one instruction doing the same arithmetic on a whole vector of values at once instead of one at a time. Codecs spend their hot loops running identical math across long buffers of samples, exactly where vectorization […]
Vibe-coding WebRTC
Well, that title is clickbait for Hacker News. The honest title would have been “using AI to tackle long-standing WebRTC issues.” Posts on webrtcHacks are rare these days, and in German we would say there are Unkenrufe that WebRTC is dead. It is not. It is the infrastructure for meetings, game streaming, and voice AI, […]
WebRTC vs. MoQ by Use Case
This might be my first editorial style post here. Fippo’s Is everyone switching to MoQ from WebRTC? started some threads on MoQ vs. WebRTC. I started to respond, but my responses quickly became too long so I decided to go even deeper with a post here. Fippo’s post shows hard data that Media over QUIC […]
Is everyone switching to MoQ from WebRTC?
It is time for another edition of “Is everyone switching to…“. Cloudflare recently published a blog post about Media over Quic (MoQ) which made a number of statements about WebRTC that require some “clarification”. Let us start with that and look at MoQ and WebTransport after that. An odd understanding of WebRTC The blog post […]
