.# Abstract
This document defines the Matroska codec mappings, including the codec ID, layout of data
in a Block Element and in an optional CodecPrivate Element.
{mainmatter}
Matroska is a multimedia container format. It stores interleaved and timestamped audio/video/subtitle data using various codecs. To interpret the codec data, a mapping between the way the data is stored in Matroska and how it is understood by such a codec is necessary.
This document intends to define this mapping for many commonly used codecs in Matroska.
This document is a work-in-progress specification defining the Matroska file format as part of the IETF Cellar working group. It uses basic elements and concept already defined in the Matroska specifications defined by this workgroup [@!Matroska].
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [@!RFC2119] [@!RFC8174] when, and only when, they appear in all capitals, as shown here.
