Description: Set of command-line tools to work with Matroska files
Matroska is a new multimedia container format, based on EBML (Extensible
Binary Meta Language), which is a kind of binary XML.
These tools allow to manipulate Matroska files.
- mkvmerge is a tool to create Matroska files from other formats
- mkvinfo allows to get information about the tracks in a Matroska file
- mkvextract can extract tracks from Matroska files to other formats
- base64tool can encode and decode base64
.
This package only provides command-line tools. For graphical tools, you
should install the mkvtoolnix-gui package.
