Build Status Coverage Status

A Javascript library to validate content with the MPEG DASH streaming format

Usage (Node JS)

npm install --save dash-validator

Example implementation:

const DashValidator = require("dash-validator");

const validator = new DashValidator("http://example.com/test.mpd");
validator.load().then(() => {
  console.log("Loaded manifest");
  console.log(validator.duration());
  validator.verifyAllSegments(verifyFn).then(result => {
    console.log(result);
  });
}).catch(console.error);

function verifyFn(headers) {
  return (typeof headers["x-my-custom-header"] !== "undefined");
}

To verify dynamically updating manifests:

validator.load().then(() => {
  validator.validateDynamicManifest(5).then((result) => {
    console.log(result);
  });
  validator.on("invalidplayhead", (data) => {
    console.log(data);
  });
  validator.on("checking", data => {
    const mpd = data.mpd;
    const headers = data.headers;
    console.log("Playhead: " + new Date(mpd.timeAtHead));
  });
});

Usage (Browser)

<script src="/dist/dashvalidator.min.js"></script>
<script>
  var validator = new DashValidator("http://example.com/test.mpd");
  validator.load().then(function() {
    return validator.validateDynamicManifest(2);
  }).then(function(result) {
    var status = document.getElementById("status");
    if (result.ok == result.iterations) {
      status.innerHtml = "All OK";
    }
  });
</script>
