iso-bmff

Minimal pure Rust AVIF writer (bring your own AV1 payload)

Pure-Swift Common Media Application Format (CMAF) + ISO BMFF foundation. Read, write, validate fragmented MP4 / CMAF media across macOS, iOS, iPadOS, tvOS, watchOS, visionOS, and Linux. Opt-in CMAFKitDRM library for typed pssh decoding of 9 DRM systems. Zero C vendoring, Swift 6.2 strict concurrency.

Pure-Go MP4/M4A muxer and demuxer for AAC-LC, Opus, and FLAC audio, the container companion to go-aac / go-opus / go-flac. No cgo, no external binaries.

Blazing fast non-allocating ISO BMFF container parser

Deterministic encode/decode engine for Zephyra's layered video format – losslessly embeds source video + timeline data inside a standard, playable mp4 via acustom ISO-BMFF box. Byte-exact round-trip, zero runtime dependencies.

🎬 Offline-first, Dockerized CLI to repair broken/unplayable video containers (lossless when possible) and transcribe speech with 4 swappable local engines — no cloud, no API keys.

Parses MP4 containers atom-by-atom to explain why a video fails on Unity WebGL and mobile, then re-encodes it to spec — CLI, batch script, and drag-and-drop web app.

MP4/ISO-BMFF box parser in Standard ML: byte-accurate box tree, find/path navigation, payload slicing, and typed ftyp/mvhd/tkhd/mdhd parsing

Read-only EXIF 3.1 / XMP / IPTC / QuickTime / RIFF metadata extraction for JPEG, ISO BMFF, TIFF, JXL, and AVI containers in PHP.

Fast, safe, FFmpeg-free media toolkit for Rust — inspect, remux, trim, and extract MP4, MOV, MKV, WebM, WAV, and MP3 with a native zero-unsafe engine.
