Smelter

What it does

Smelter is a toolkit for programmatic live video composition. Combine multimedia, enrich content with text, custom shaders, embedded websites, and more - all with ready-to-use React components.

Low-latency video compositing tool with seamless developer experience. Use it for live streaming, broadcasting, video conferencing and more.

Compose and stream your videos with minimal delay. Smelter means seamless experience for use cases that demand immediate responsiveness. Combine live feeds, screen recordings, and pre-recorded videos into a single composition. Mix multiple inputs at the same time without any frame drops. Add text, animations, transitions, and graphics seamlessly — both to live and to recorded videos. Change layouts on the fly. Run high-performance video processing directly in the browser with WASM. Also, leverage GPU processing by rendering with WebGL or WebGPU. Thanks to the declarative API, Smelter is quick to pick up for anyone familiar with web development. Which means you can customize it in no time.…from smelter.dev

  Smelt — an open source test runner for chip developers2024 · silogy-io.github.io · ▲77

  Hey everyone, James from Silogy here. We’re excited to open-source our test runner, Smelt. Smelt is a simple and extensible test runner optimized for chip development workflows.

  Talanoa▲345

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I got laid off from Meta and created a minor hit on Steam▲1,581

  I was at FB/Meta from late 2013 to early 2023, mostly working in the compiler/runtime spaces. I got hit in the spring 2023 layoff wave. I immediately started making games in my newfound free time (a lifelong interest, and I even worked in AA(A?) back ca. ~2000), and in October 2023 I stumbled upon the idea of a roguelike pachinko/plinko game inspired by Luck Be A Landlord. Things snowballed quickly, I started talking to publishers, then worked like crazy through all of 2024, almost the hardest I've ever worked in my career, and launched the game in December 2024. It's sold…
