Parser and Writer for GoPro Metadata Format (GPMF)

WIP: Currently successfully parses all raw test data and logs the results.

Design Goals

• Linux Philosophy, each tool does one thing and does it well
• Can be integrated in other tools, and in other languages than Rust
• Focus on clean, easy to understand code (no macros)
• Performant (but not at the expense of the previous item)
• Easy to read detailed log in order to be able to debug problems
• Memory safe parser
• Zero security vulnerabilities. Avoid problems found in other tools e.g.: GoPro GPMF-parser Vulnerabilities
• Never generate exceptions, i.e.: Should never panic.
• Should pass fuzz tests i.e.: handle junk data
• Should avoid DOS attacks. Possibly Add max buffer lengths.
• Gracefully recover from errors
• Handle unknown tags

Reporting Issues

If you have a file that is not handled please submit an issue, attaching the raw metadata file
