SpawnDev.EBML

Name	Package	Description
SpawnDev.EBML		An extendable .Net library for reading and writing Extensible Binary Meta Language (aka EBML) documents. Includes schema for Matroska and WebM.

Demo

Blazor EBML Editor

Version 2 changes

• The library now uses string paths instead of the Enums found in version 1.
• The library now uses (and includes) EBML XML schema files:
• EBML
• Matroska

Note: The Matroska schema xml is currently also used for WebM ebml documents.

Usage

using SpawnDev.EBML;
using SpawnDev.EBML.Elements;

// Create the EBML parser with the default configuration
// default configuration supports matroska and webm reading and modification
var ebml = new EBMLParser();
// get a stream containing an EBML document (or multiple documents)
using var fileStream = File.Open(@"TestData/Big_Buck_Bunny_180 10s.webm", FileMode.Open);
// parse the EBML document stream (ParseDocuments can be used to parse all documents in the stream)
var document = ebml.ParseDocument(fileStream);
if (document != null)
{
    Console.WriteLine($"DocType: {document.DocType}");
    // or using path
    Console.WriteLine($"DocType: {document.ReadString(@"/EBML/DocType")}");

    // Get an element using the path
    var durationElement = document.GetElement<FloatElement>(@"/Segment/Info/Duration");
    if (durationElement != null)
    {
        var duration = durationElement.Data;
        var durationTime = TimeSpan.FromMilliseconds(duration);
        Console.WriteLine($"Duration: {durationTime}");
    }
}

// Create a new matroska EBML file
var matroskaDoc = ebml.CreateDocument("matroska");
Console.WriteLine($"DocType: {matroskaDoc.DocType}");
