Open-source streaming API from ingest to player

Hi there HN! I'm Matthias and I've been into video streaming for quite a while now. Over the years I've built plenty of small setups, often CLI tools to test and debug streaming video. About a month ago, during my annual holiday, I started working on a simple API on top of my CLI tools. It's time consuming to craft and run multiple ffmpeg jobs, get GOP / keyframes right, merge playlists, package to HLS, ... One thing led to another and I eventually started exploring HLS interstitials, VMAP / VAST and dynamic ad insertion, MSE / EME (HLS.js in general), React (perf) as a player…

    Hey HN community! I'm one of the lead devs of this project at fal.ai and we created an open source lightweight video editor powered by the latest media AI models. The main goal was to tackle some challenges when dealing with complex media handling and encoding on the browser. It all started as an internal experiment but as we tackled some of the issues it was clear there could be some value sharing it with the open source community. Some of the key points and tech stack details: - It uses IndexedDb, so all data is local (i.e. no auth, no cloud db) - Multiple AI models for video, image, music…

  • I've been making JavaScript sandbox alone for 6 years2022 · playcode.io · ▲397

    Hi HN! Thanks for your attention to my post. It was a big challenge to run most of Node.js packages in browser, fast moreover. Virtual File system, resolve import/export. I got cold many times, depressions, burned out, yet still alive and finished it. Many guys helped me with an advice. Many users give a lot of positive feedback. There are 200,000 monthly unique users. I work full time now because of the freemium business model. To be honest - I am happy after many years of hard work.

    I built an indie, browser-based MMORPG2024 · alpha.reconquer.online · ▲340

    I've been working on an MMORPG that is now in alpha as a solo developer. Here are the major open source technologies that I use: Blender - 3D modeling software for creating the overall environment and every game object. I've gotten a lot of CC and Public Domain assets from https://poly.pizza GLTF - I export assets from blender to the GLTF asset format JSON - I write a JSON config for every game object that describes things like its name, its interactions, its collisions, etc. Node.js exporter - I iterate over the environment and every asset to create a scene hierarchy. I use…

  • I just open sourced Muxamp, a streaming media playlist in Node.js2013 · github.com · ▲32

    Hey HN! I've been working on Muxamp for over a year now, and I decided that there's no point in keeping the source closed. (I never planned on making money from it.) I've learned a lot since I started, and I hope others can benefit from its release--and perhaps teach me a thing or two as well :)

  • Video CommanderApr 2026 · video-commander.com · ▲87

    I've been building open-source tools in the video/multimedia space for 10+ years. Finally shipped the commercial product I always wanted to exist — Video Commander, a desktop app that consolidates FFmpeg, ffprobe, MediaInfo, VMAF and more into a single workspace where you can inspect, encode and analyze video. Built with Tauri + Rust backend, React frontend. FFmpeg and VMAF. Not a cool AI/LLM project, just a tool I've been heads-down building over the last six months. Happy to answer any questions!

  • Streamdal – an open-source tail -f for your data2023 · github.com · ▲148

    Hey there! This is Dan and Ustin (@uzarubin), and we want to share something cool we've been working on for the past year - an open-source `tail -f` for your data, with a UI. We call it "Streamdal" which is a word salad for streaming systems (because we love them) and DAL or data access layer (because we’re nerds). Here's the repo: https://github.com/streamdal/streamdal Here's the site: https://streamdal.com And here's a live demo: https://demo.streamdal.com (github repo has an explanation of the demo) — — — THE PROBLEM We built this because the…

    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…
