    simple-ebml-builder

    Simple DSL for building EBML byte array (mkv/webm).

    install

    npm install simple-ebml-builder
    

    Sample code

    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"
