Description[edit]

Clairmeta is a python package for Digital Cinema Package (DCP) probing and checking. This project status is Beta, the following needs to be done for the release :

Large scale tests on lots of DCPs (including D-Box, DVIs, OCAP, CCAP, ...)

Features

DCP Probe : metadata extraction of the whole DCP, including all XML fields and MXF assets inspection.
DCP Checker : advanced DCP validation tool, including (non exhaustive):
- SMPTE / Interop standard convention (naming, …)
- Integrity (MIME type, size, hash) of all assets
- Foreign file identification
- XSD Schema validation for XML files (VOLINDEX, ASSETMAP, CPL, PKL)
- Digital signature validation (CPL, PKL)
- Intra / Inter Reels integrity and coherence
- Metadata match between CPL assets and MXF headers
- Re-link VF / OV
- Picture tests : FrameRate, BitRate, …
- Sound tests : Channels, Sampling, …
- Subtitle : Deep inspection of Interop and SMPTE subtitles
DSM / DCDM Checker : basic image file sequence validation with some specific rules.

Usage

ClairMeta can be used as a general command line tool as well as a python library.

Examples for command line calls:

  python3 -m clairmeta.cli probe -type dcp path/to/dcp
  python3 -m clairmeta.cli probe -type dcp path/to/dcp -format json > dcp.json
  python3 -m clairmeta.cli probe -type dcp path/to/dcp -format xml > dcp.xml
  python3 -m clairmeta.cli check -type dcp path/to/dcp
