Description

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
