Hi! I have a few :) How close are we to having QUIC actually usable in browsers (meaning both browsers and infrastructure supports it, and it 'just works') How does QUIC get around the NAT problem? WebRTC requires STUN/TURN to get through full cone NAT, particularly the latter is problematic, since it requires a bunch of infra to run.

Chrome and Firefox support WebTransport. Safari has announced intent to support it and they already use QUIC under the hood for HTTP/3. Cloud services are pretty TCP/HTTP centric which can be annoying. Any provider that gives you UDP support can be used with QUIC, but you're in charge of certificates and load balancing. QUIC is client->server so NATs are not a problem; 1 RTT to establish a connection. Iroh is an atte…

It's all hardware accelerated, assuming the VideoDecoder has hardware support for the codec. VideoFrame is available in WebGL and WebGPU as a texture or gpu-buffer. We're only rendering after a`requestAnimationFrame` callback so decoded frames may get automatically skipped based on the display frame rate. I don't think the performance would be any worse than the tag. The only exception would be browser bugs. It defin…

Unfortunately canvas (rgb'ish) can't overlay as efficiently as (yuv'ish), so there is some power cost relative to the lowest power video overlays. It really only matters in long form content where nothing else on the page is changing though.

There's a whole "why should I care?" section in this breathless post that doesn't explain how Media over QUIC benefits either media publishers or end users - the two most important (perhaps the only important) parties involved in this exchange. So, why should I care?

My fault, I trying too hard to avoid rehashing previous blog posts: https://moq.dev/blog/replacing-webrtc/ And you're right that MoQ primarily benefits developers, not end users. It makes it a lot easier to scale and implement features; indirect benefits.
