Package Exports
- matroska
- matroska/index.js
- matroska/lib/schema
- matroska/lib/schema.js
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (matroska) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

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)
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)

# COMPLETE parsing
Complete parsing of a mkv:
```js
var matroska = require('matroska');
var url="http://download.wavetlan.com/SVV/Media/HTTP/mkv/H264_mp3(mkvmerge).mkv";
var decoder = new matroska.Decoder();
decoder.parse(url, function(error, document) {
if (error) {
console.error(error);
return;
}
console.log(document.print());
});
```
Returns:
