A Javascript library to validate content with the MPEG DASH streaming format
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));
});
});
<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>
