OxiMedia – Pure Rust Reconstruction of FFmpeg and OpenCV
Author here. OxiMedia is a clean-room reconstruction of FFmpeg and OpenCV in pure Rust. v0.1.0, 92 crates, ~1.36M lines. Key decisions: `#![forbid(unsafe_code)]` workspace-wide, patent-free codecs only (AV1/VP9/Opus/FLAC -- no H.264/H.265/AAC ever), async on Tokio, zero C/Fortran deps in default features, native WASM target. This is v0.1.0 -- APIs are stabilized but not yet battle-tested at scale. Performance benchmarks vs FFmpeg/rav1e/dav1d coming soon. Feedback on API design welcome, especially the filter graph and transcoding pipeline. GitHub:…
In plain words
OxiMedia is a Rust-based reconstruction of FFmpeg and OpenCV, offering media processing and computer vision capabilities without C dependencies in its default build. It supports patent-free codecs including AV1, VP9, Opus, and FLAC, uses async Tokio throughout, and forbids unsafe code workspace-wide. The project includes 92 crates totaling approximately 1.36 million lines and provides native WebAssembly support. At version 0.1.0, the APIs are stabilized but not yet extensively production-tested at scale.

Hi HN, I built typed-ffmpeg, a Python package that lets you build FFmpeg filter graphs with full type safety, autocomplete, and validation. It’s inspired by ffmpeg-python, but addresses some long-standing issues like lack of IDE support and fragile CLI strings. What’s New in v3.0: • Source filter support (e.g. color, testsrc, etc.) • Input stream selection (e.g. [0:a], [1:v]) • A new interactive playground where you can: • Build filter graphs visually • Generate both FFmpeg CLI and typed Python code • Paste existing FFmpeg commands and reverse-parse them into graphs Playground link:…
- VAVidStudio, a browser based video editor that doesn't upload your filesApr 2026 · vidstudio.app · ▲301
Hi HN, I built VidStudio, a privacy focused video editor that runs in the browser. I tried to keep it as frictionless as possible, so there are no accounts and no uploads. Everything is persisted on your machine. Some of the features: multi-track timeline, frame accurate seek, MP4 export, audio, video, image, and text tracks, and a WebGL backed canvas where available. It also works on mobile. Under the hood, WebCodecs handles frame decode for timeline playback and scrubbing, which is what makes seeking responsive since decode runs on the hardware decoder when the browser supports it. FFmpeg…

Inspired by the "ffmpeg by examples" comments, here's a simple script that pulls it all together. Set your OpenAI API key env var and make the script executable, and you're golden.

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…
