# node-matroska
Matroska library written for nodejs

# Fork of node-ebml
It is a fork of https://github.com/themasch/node-ebml

# VERY Fast parsing

Fast and incomplete parsing of a mkv file:   (we keep only metadatas)
```js
var matroska = require('matroska');

var url="http://download.wavetlan.com/SVV/Media/HTTP/mkv/H264_PCM(mkvmerge).mkv";

matroska.Decoder.parseInfoTagsAndAttachments(url, function(error, document) {
	if (error) {
		console.error(error);
		return;
	}

console.log(document.print());
});
```

Returns a tree:  (format:  offset#tagId  * node)
