A Javascript library to parse Apple HLS MPEG Transport Stream segments

## Usage (Node JS)

```

npm install --save hls-ts

```

The library implements the `Writable` stream interface and acts a a "sink". For example to download

and parse an HLS MPEG Transport Stream segment:

```

const request = require("request");

const hlsTs = require("hls-ts");

request.get("http://example.com/seg10.ts")

.pipe(hlsTs.parse())

.on("finish", function() {

  // Obtain all programs found in the Transport Stream

  const programs = hlsTs.programs;

  // Obtain all packets for a specific program stream

  const avcPackets = hlsTs.getPacketsByProgramType("avc");

  // Obtain the payload for a program stream

  const avcPayload = hlsTs.getDataStreamByProgramType("avc");

  // where avcPayload.data is a Uint8Array

  const avcParser = hlsTs.createAvcParser(avcPayload);

  // Obtain NAL units

  const nalUnits = avcParser.getNalUnits();

});

```

## Usage (Browser version)

```

  var xhr = new XMLHttpRequest();

  var url = "http://example.com/hls/seg-10s.ts";

  var parser = new window.HlsTs({ debug: false });

  xhr.responseType = "arraybuffer";

  xhr.onloadend = function() {

    var buffer = xhr.response;

    var data = new Uint8Array(buffer);

    parser.parse(data).then(function() {

      // Obtain all programs found in the Transport Stream

      var programs = parser.getPrograms();

      // Obtain all packets for a specific program stream

      var avcPackets = parser.getPacketsByProgramType("avc");

      

      // Obtain the payload for a program stream

      var avcPayload = parser.getDataStreamByProgramType("avc");

      // where avcPayload.data is a Uint8Array

      var avcParser = parser.createAvcParser(avcPayload);

      // Obtain NAL units

      var nalUnits = avcParser.getNalUnits();

    }).catch(function(err) { console.error(err.message); }).then(done);

  };

  xhr.open("GET", url);

  xhr.send();

```
