gamut-heic

gamut-heic is a pure-Rust HEIC/HEIF encoder — HEVC (H.265) bitstreams wrapped in an ISOBMFF container.

Goals

Part of the gamut workspace, this crate exists to provide HEIC encoding that is:

Memory-safe on hostile input. #![forbid(unsafe_code)], deleting the memory-corruption bug class that has bitten the C HEVC/HEIF stacks.
Clean-slate from the spec. Implemented directly from the HEVC and HEIF specs (see ../../references/) rather than wrapping libde265/libheif.
Sharing the AVIF container. It reuses gamut-isobmff — the same ISOBMFF box writer that backs AVIF — and color handling from gamut-color.

Note: HEVC is patent-encumbered, unlike gamut's royalty-free focus formats; this crate is scaffolding and may move or be dropped as the project's scope sharpens (see the workspace README's "Scope").

Usage

No public API yet — implementation pending. It will follow the same shape as gamut-avif: an encoder type implementing [gamut_core::EncodeImage], reachable through the umbrella crate's heic feature.

Status

Placeholder — implementation pending.

Roadmap

HEVC intra still-image encoding, wrapped via gamut-isobmff (hvc1 items).
