Replacing WebRTC: real-time latency with WebTransport and WebCodecs
10 projects | news.ycombinator.com | 30 Oct 2023

I'm currently working with WebCodecs to get (the long awaited) frame-by-frame seeking and reverse playback working in the browser. And it even seems to work, albeit the VideoDecoder queuing logic seems to give some grief for this. Any tips on figuring out how many chunks have to be queued for a specific VideoFrame to pop out?
An aside: to work with video/container files, be sure to check the libav.js project that can be used to demux streams (WebCodecs don't do this) and even used as a polyfill decoder for browsers without WebCodec support!

Bun, JavaScript, and TCO

To use this in Bun, you’d have to start Bun with the environment variable “BUN_JSC_useDollarVM=1” and then $vm.createBuiltin(mySourceCodeString)
When using this intrinsic, if any of the arguments are incorrect or it cannot otherwise enable it, the entire process will probably crash. In debug builds of JSC it will have a nicer assertion failure but that is not enabled in release builds

Ah, good, let me introduce you to the wonderful world of the Chrome Devtools Protocol! (fka Chrome Remote Debugging Protocol)
I love this API for almost everything browser related. I built my RBI product atop this (BrowserBox: https://dosyago.com), and I think it's a drastically underrated API.
Also, it works out of the box in Edge, Brave, Chromium, and many parts of CRDP are supported by Firefox and Safari^1
