Application Insights Query SDK

The [Microsoft.Azure.ApplicationInsights NuGet package][1] contains the query SDK for App Insights. Here's a bare-minimum setup with a client ready to make calls:

AAD Authentication

using System;
using Microsoft.Azure.ApplicationInsights;
using Microsoft.Rest.Azure.Authentication;
using System.Collections.Generic;

	url = require('url'),
	ffmpeg = null;
    
var livestream = function (req, resp) {
    // For live streaming, create a fragmented MP4 file with empty moov (no seeking possible).

	var input = 'udp://225.1.1.1:8208';

Lesson Learnt, Streaming Producer / Consumer issue using:
