Simple DSL for building EBML byte array (mkv/webm).
npm install simple-ebml-builder
Sample code
TypeScript
import * as EBML from "simple-ebml-builder";// EBML element object. The name is EBMLVersion and body is 1. The Size is generated automatically.
EBML.element(EBML.ID.EBMLVersion, EBML.number(1));
// 0x01FFFFFFFFFFFFFF is assigned as the element size for unknownSizeElement.
EBML.unknownSizeElement(EBML.ID.EBMLVersion, EBML.number(1));
// Element can have multiple elements.
EBML.element(EBML.ID.Info, [
EBML.element(EBML.ID.TimecodeScale, EBML.number(1000000)),
EBML.element(EBML.ID.MuxingApp, EBML.string("MuxingApp")),
EBML.element(EBML.ID.WritingApp, EBML.string("WritingApp")),
]);
// Build single Uint8Array from element.
EBML.build(EBML.element(EBML.ID.EBMLVersion, EBML.number(1))); // => Uint8Array.of(0x42, 0x86, 0x81, 0x01)
// dumpBytes is useful for debugging.
console.log(EBML.dumpBytes(EBML.build(EBML.element(EBML.ID.EBMLVersion, EBML.number(1))))); // "0x42, 0x86, 0x81, 0x1"
