MediaConch implementation and policy checking on FFV1, Matroska, LPCM, and more Jérôme Martinez MediaArea.net SARL
What is MediaConch? A conformance checker Implementation checker Policy checker Reporter Fixer
What is MediaConch? A conformance checker ... in four formats Command line Graphical interface Server (REST API) Web interface
MediaConch and open source GPLv3+ and MPLv2+ Relies on MediaInfo (metadata extraction tool) Uses Qt, sqlite, libevent, libxml2, libxslt, libexslt...
Formats Prioritizes... Matroska FFV1 PCM But also... Can accept any format supported by MediaInfo Mainly as a policy checker Implementation checker for other formats can be developed in the future
Versatile Binaries are provided for: Windows Mac Linux (Ubuntu, Debian, Fedora, OpenSUSE...) Can be ported on other distros (BSD...) Input can be from: Files (local/network) FTP/FTPS/SFTP HTTP/HTTPS Amazon S3
Standardization Matroska is widely used but not standardized FFV1 is preferred by some entities but not standardized
CELLAR: IETF workgroup Open standards group Goal to standardize Matroska/FFV1/FLAC A lot of progress, especially with Matroska/EBML specs
PREFORMA Sponsorship 3‑year project (2015‑2017) Sponsored by European Union Open source license is required!
PREFORMA Sponsorship 3 software projects: Video (Matroska/FFV1/PCM): MediaConch (MediaArea) Document (PDF): VeraPDF (Open Preservation Foundation) Image (TIFF): DPF Manager (Easy Innova)
Whatʹs next? Still under development asynchronous mode (handling of huge libraries) Better user interface Statistics Standardize Matroska and FFV1 More conformance tests
Want to help us? CELLAR participation Implementing CRC‑32 into Matroska and FFV1 Quality checking for all interfaces Bug tracking and reporting Documentation Your weird video errors Your codebase!
