Matroska has several components that are licensed in different ways to maximize its software and hardware adoption.
|LibEBML||A simplified binary extension of XML for the purpose of storing and manipulating data in a hierarchical form with variable field lengths.||LGPL|
|LibEBML2||Another EBML parser with a similar interface to libEBML but written in C.||BSD|
|LibMatroska||A C++ libary to parse Matroska files, it requires libEBML or libEBML2.||LGPL|
|Core C||A low level API layer for the C programming language.||BSD|
There is no cost to use the components as long as you respect the license it is released under.
To help Matroska evolve we do encourage companies that release commercial hardware or software products that use Matroska or EBML to become a sponsor. In exchange for your sponsorship, we allow the sponsor to use the Matroska logo's and trademarks in packaging, physical products, promotional material, and on their websites.
