About:
Mp4v2 is a C++ library that provides a comprehensive API for reading, writing, and modifying MP4 container files. It offers low-level access to metadata and media streams without requiring a full media framework. This makes it an ideal solution for developers needing to manipulate file tags, chapters, and track information programmatically.

Key Features:

Full read/write access to MP4 metadata (tags, artwork, chapters)
C++ library with bindings for Python and other languages
Supports ISO standard MP4 (MPEG-4 Part 14) files
Lightweight with no external media framework dependencies
Command-line utilities included for direct file manipulation

Use Cases:

Batch editing music or video metadata in media libraries
Embedding or extracting cover art from video files
Adding chapter markers to video files for better navigation
Automated MP4 file processing in build pipelines

Alternatives:

ffmpeg – FFmpeg is a massive multimedia framework that can handle metadata but is much heavier and complex than Mp4v2.
AtomicParsley – AtomicParsley is a command-line tool specifically for MP4 metadata, whereas Mp4v2 provides a full library for programmatic integration.
