MediaConch now supports plugins including VeraPDF and DPFManager!

The Online MediaConch GUI enables accessibility across platforms.





MediaConch now supports plugins for other implementation checkers such as the DPF Manager for TIFF files and VeraPDF’s checker for PDF files. MediaConch will select the appropriate implementation checker based upon the associated format as determined by MediaInfo.

To facilitate large-scale testing and provide research to efforts in the IETF Cellar working group, we’ve created a website to catalog discovered sample Matroska files in a manner that allows faceted browsing according to their technical characteristics and their conformance status according to the MediaConch implementation checker. See this work in development, which contains a collection of over 64,000 Matroska files.
