mkvalidator

Movie and TV-shows aficionados as well anyone who have a collection of high-definition videos are likely to grab large Matroska files from various sources. However, because you are grabbing these videos from less-reliable sources at times, it is only natural that you would want to check the integrity of the files and for spec conformance.

As the name suggests, mkvalidator is a tiny tool designed to help you verify MKV as well as WebM files to ensure that they include all elements as reported in the EBML DocType version of the MKV. To be more precise, the utility can check and output errors with and without errors, show details for the valid data and determine whether the file is using DivX specific extensions.

Take note that the app does not come with an interface, but rather it can be run via Command Line or PowerShell. While this aspect can make things faster and convenient for advanced users, it can also constitute a deterrent for the less-technical ones.

Nevertheless, the program is swift and convenient for anyone who wants to check for bad tracks or cue entries, profile violations, missing mandatory elements from the metadata or various EBML junk data that can employ unknown IDs.
