EBML Block Parser

ebml-block is a specialized JavaScript library designed to parse the raw binary data of an EBML Block or SimpleBlock structure. These blocks typically contain actual media frames (video, audio) and their associated metadata, such as timecodes and keyframe indicators, commonly found within Matroska (MKV) and WebM container formats. The package's current stable version is 1.1.2, released in March 2017. While functional, its development has been dormant since then, suggesting a maintenance-only status rather than active feature development. It is crucial to note that ebml-block does not parse entire EBML documents; instead, it expects a pre-extracted Buffer representing a single Block element. This differentiates it from broader EBML parsers, making it a low-level utility for processing specific data chunks within a larger EBML stream, often used in conjunction with a full EBML stream decoder.
