This is tied to efforts to refine the EBML and Matroska specifications so that what is and isn't Matroska conformance is more clear. To support development of a conformance checker we are seeking examples of files that may contain conformance issues. In addition to files, descriptions of workflows to create compromised Matroska files are also helpful. All Matroska file types such as mkv, mka, mk3d, webm are helpful. I'm also interested in samples of EBML files that are not Matroska or webm, if such files can be shared.
