As new demuxers are added, this will get quite full of files, so it'll be good to have a separate folder for these. To avoid too many chained namespaces, the Containers subdirectory is not also a namespace, but the Matroska folder is for the sake of separating the multiple classes for parsed information entering the Video namespace.
