Requirements

This library has the following requirements:

A working FFmpeg and FFprobe installation. On Windows, you can download official ffmpeg and ffprobe binaries and place them on your path.

This project heavily uses the ffmpeg-python wrapper. And uses python-json-logger for logging.

Usage

If installed, there should be a command-line tool available.

For extracting USMs:

wannacri extractusm /path/to/usm/file/or/folder --key 0xKEYUSEDIFENCRYPTED

For creating USMs:

wannacri createusm /path/to/vp9/file --key 0xKEYIFYOUWANTTOENCRYPT
