A (WIP) Python library for parsing, extracting, and generating Criware's various audio and video file formats. If you're interested in reading more about USM, you can read my write-up about it here
This currently supports the following formats with more planned:
✅: Implemented and tested ❓: Should work but not tested ❌: Not implemented
x/y: Extract support / Create support
| Codec | Not-encrypted | Encrypted |
|---|---|---|
| VP9 | ✅ / ✅ | ✅ / ✅ |
| H.264 | ✅ / ✅ | ✅ / ❓ |
| Prime | ❓ / ❌ | ❓ / ❌ |
| Codec | Not-encrypted | Encrypted |
|---|---|---|
| CRI HCA | ✅ / ❌ | ✅ / ❌ |
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.
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
