rsmp4decrypt

MP4 decryption for Rust - Bento4 mp4decrypt as a library and CLI.

        

---

• Idiomatic API - small, focused Rust surface over Bento4 decryption
• CLI parity for core inputs - accepts --key, --fragments-info, and --show-progress
• Track ID and KID keys - use decimal track IDs or 128-bit hexadecimal KIDs
• File and memory decryption - decrypt from paths or in-memory buffers
• Progress callbacks - report Bento4 progress in library code or through the bundled CLI
• Reusable context - build a Mp4Decryptor once and reuse it across many decrypt calls
• Process-isolated file decryption - run multiple file decrypts in parallel through IsolatedMp4Decryptor
• Async file decryption - enable the tokio feature for decrypt_file_async without spawn_blocking
• Typed errors - all public failures are surfaced through rsmp4decrypt::Error
• Thread-safe usage - internal serialization keeps Bento4 stable across concurrent callers
• Vendored native sources - published crates build from the checked-in vendor/bento4-src snapshot
