OxiMedia 0.1.0 Released — The Sovereign Media Framework in Pure Rust

Big news for the COOLJAPAN ecosystem.

Today we shipped OxiMedia 0.1.0 — the world’s first complete sovereign media framework written entirely in Rust.

No C. No FFI. No patents. No royalties.
Just clean, memory-safe, high-performance multimedia processing that runs everywhere (native, WASM, embedded, browser).

Why OxiMedia matters

For decades, multimedia meant depending on FFmpeg, OpenCV, GStreamer, and a mountain of C/C++ code with patent risks and license headaches.

OxiMedia ends that era.

• 97 crates · 1.36M+ SLoC of pure Rust
• #[forbid(unsafe_code)] enforced everywhere
• All codecs are royalty-free and patent-free by design
• Full FFmpeg-level decoding/encoding + OpenCV-level computer vision
• Native WASM + WebGPU support (runs in the browser with zero server)
• SIMD everywhere, zero-copy pipelines, async-first architecture

What’s inside 0.1.0

• Video/Audio container support (MP4, MKV, WebM, MOV, etc.)
• Codecs: H.264, H.265, AV1, VP9, Opus, AAC (all royalty-free paths)
• Image processing (PNG, JPEG, WebP, AVIF, HEIC)
• Computer vision primitives (the OpenCV core features reimplemented)
• Real-time streaming & transcoding pipelines
• GPU acceleration via wgpu (works on desktop, mobile, and browser)
• Python & Node.js bindings ready (coming in 0.1.1)

This is just the beginning

OxiMedia is the multimedia backbone for the entire COOLJAPAN stack — powering VoiRS (TTS/Voice), OxiGDAL, tenflowers, torsh, and the upcoming AI agent video capabilities in mielinOS.

And because it’s 100% pure Rust, it compiles to the same binary whether you’re running on Linux, Windows, macOS, iOS, Android, or directly in the browser.

Star the repo if you want a future where multimedia is sovereign again.

More releases coming this week (including 0.1.1 with even more codecs and bindings).

The Rust media revolution has officially begun.
