## install

```
npm install ebml-block
```

## example

```javascript
const fs = require('fs')
const ebml = require('ebml')
const ebmlBlock = require('ebml-block')

var decoder = new ebml.Decoder()

decoder.on('data', function (chunk) {
  if (chunk[1].name === 'Block' || chunk[1].name === 'SimpleBlock') {
    var block = ebmlBlock(chunk[1].data)
    console.log(block)
  }
})

fs.createReadStream('media.mkv').pipe(decoder)
```

### output format
