A hands-on introduction to video technology: image, video, codec (av1, vp9, h265) and more (ffmpeg encoding). Translations: 🇺🇸 🇨🇳 🇯🇵 🇮🇹 🇰🇷 🇷🇺 🇧🇷 🇪🇸
New generation entropy codecs : Finite State Entropy and Huff0
Lossless compression C library built for ultra-fast decode. Faster than LZ4 (+35% to 105%+; best on ARM64), at a better ratio. Official Rust, Python, Node.js, Go and WASM bindings. Write-once/read-many, with optional seekable archives for O(1) random access.
Fast integer compression in C using the StreamVByte codec
Open source Windows x64 PE packer and crypter. Compresses and encrypts executables with a custom virtual machine into a self extracting stub.
Brotli compression library for Go (RFC 7932), pure Go, no cgo, encoder + decoder, highly optimized
JS implementation of nimn specification
Zip-Ada: a standalone, portable pure Ada library for .zip archives. Includes LZMA and BZip2 byte stream encoder & decoder pairs.
