Thanks!
Where did you find that URL? It's incomplete, the right one is http://playready.directtaps.net/smoothstreaming/TTLSS720VC1/To_The_Limit_720.ism/manifest, but it is unlikely to work. Other files have been posted at: Microsoft's SmoothStreaming samples files, that said, I don't believe that Microsoft is providing a CORS header that works for Chromecast.
We do provide some very simple media that you can host yourself. And we provide a very simple server, if you need that to host and provide a CORS header as well.

I am new to azure notification hub. I tried from the documentation. But not able to do the name . Need some help on this .
Tried from the below link
How to register devices to Azure Notification Hub from server side(with NodeJS sdk) ?
Not sure about the params.
var azure = require('azure-sb');
var notificationHubService = azure.createNotificationHubService('<Hub Name>','<Connection String>');
var payload={
alert: 'Hello!'
};
notificationHubService.createRegistrationId(function(error, registrationId, response){
if(!error){
console.log(response);
console.log(registrationId);
//RegistrationDescription registration = null;
//registration.RegistrationId = registrationId;
//registration.DeviceToken = req.body.token;
notificationHubService.apns.createOrUpdateNativeRegistration(registrationId, req.body.token, req.token.upn, function(error, response){
if(!error){
console.log('Inside : createOrUpdateNativeRegistration' + response);
notificationHubService.apns.send(null, payload, function(error){
if(!error){
// notification sent
console.log('Success: Inside the notification send call to Hub.');
}
});
}
else{
console.log('Error in registering the device with Hub' + error);
}
});
}
else{
console.log('Error in generating the registration Id' + error);
}
});
While creating registrationID which registration id i have to pass there. What is request.body.token and what is request.token.upn. I need it for apns
While creating registrationId , you dont have to pass any id. **createRegistrationId(callback)** takes callback as a parameter which creates a registration identifier.
As per the overall implemetation:
/**
* Creates a registration identifier.
*
* #param {Function(error, response)} callback `error` will contain information
* if an error occurs; otherwise, `response`
* will contain information related to this operation.
*/
NotificationHubService.prototype.createRegistrationId = function (callback) {
validateCallback(callback);
var webResource = WebResource.post(this.hubName + '/registrationids');
webResource.headers = {
'content-length': null,
'content-type': null
};
this._executeRequest(webResource, null, null, null, function (err, rsp) {
var registrationId = null;
if (!err) {
var parsedLocationParts = url.parse(rsp.headers.location).pathname.split('/');
registrationId = parsedLocationParts[parsedLocationParts.length - 1];
}
callback(err, registrationId, rsp);
});
};
Once you are done with RegistrationID Creation then you can call createOrUpdateRegistration(registration, optionsopt, callback) and here is the overall implementation for the same:
/**
* Creates or updates a registration.
*
* #param {string} registration The registration to update.
* #param {object} [options] The request options or callback function. Additional properties will be passed as headers.
* #param {object} [options.etag] The etag.
* #param {Function(error, response)} callback `error` will contain information
* if an error occurs; otherwise, `response`
* will contain information related to this operation.
*/
NotificationHubService.prototype.createOrUpdateRegistration = function (registration, optionsOrCallback, callback) {
var options;
azureutil.normalizeArgs(optionsOrCallback, callback, function (o, c) { options = o; callback = c; });
validateCallback(callback);
if (!registration || !registration.RegistrationId) {
throw new Error('Invalid registration');
}
var webResource = WebResource.put(this.hubName + '/registrations/' + registration.RegistrationId);
registration = _.clone(registration);
var registrationType = registration[Constants.ATOM_METADATA_MARKER]['ContentRootElement'];
delete registration[Constants.ATOM_METADATA_MARKER];
delete registration.ExpirationTime;
delete registration.ETag;
if (!registration.Expiry) {
delete registration.Expiry;
}
registration.BodyTemplate = '<![CDATA[' + registration.BodyTemplate + ']]>';
var registrationXml = registrationResult.serialize(registrationType, registration);
this._executeRequest(webResource, registrationXml, registrationResult, null, callback);
};
You can find the complete implementation of NotificationHubService.js here.
Hope it helps.
I want to send push notifications on a device I have device ID , how can I send notifications on that device.

The changes are relatively simple while playing with this service. Just pretty much forcing the raw node HTTP objects to the middleware.
Logs are showing the UDP requests to the xray service are working as expected. Yet in the console I see no results.
Anyone have any ideas?
I have been trying to send search history in the background page and send response back to front page. I am using message parsing .
I am unable to send response back after searching history.
--------background.js-------------
var SECONDS_PER_WEEK = 1000 * 60 * 60 * 24 * 7;
chrome.extension.onMessage.addListener(
function(request, sender, sendResponse) {
if(request === "getHistory"){
var value = getHistory();
console.log("Response" , value);
sendResponse(value);
}
}
);
function getHistory(){
var current_time = new Date().getTime();
var timeToFetch = current_time - SECONDS_PER_WEEK;
return chrome.history.search({
'text' : '',
'startTime' : timeToFetch
},
function(resp){
return resp;
});
}
The problem lies here itself as on logging I get 'undefined' as response.
Can anyone direct me to the solution
Most of the Chrome.* API functions are asynchronous so try doing it something like this:
background.js
var SECONDS_PER_WEEK = 1000 * 60 * 60 * 24 * 7;
chrome.extension.onMessage.addListener(function(request, sender, sendResponse) {
if(request === "getHistory"){
getHistory(sendResponse);
return true;
}
});
function getHistory(sendResponse){
var current_time = new Date().getTime();
var timeToFetch = current_time - SECONDS_PER_WEEK;
chrome.history.search({
'text' : '',
'startTime' : timeToFetch
},
function(resp){
console.log("Response: " + resp);
sendResponse(resp);
});
}
I'm writing my first "serious" node.js module and I need some advices/best practices on a couple of things...
Please read comments in the code for the questions!

client.on('data', function(data) {
console.log(data);

return new exports.Client(options);
};
/**

var offset, part;
