With Windows Azure Media Services, you can upload, manage, encode, and stream your

media to a variety of devices

on a cloud scale.

Maybe you have a bunch of training videos you want to share with your global employee contingent, in the office and on the go …

… or maybe you are hosting the Olympic Games and need to stream to hundreds of millions of consumer devices, with peaks of 100x the standard traffic …

… or maybe you’re a TV network, a cellular carrier, a radio station, an ad agency, a consumer video website … and you want to stop worrying about infrastructure and embrace cloud scale.

MANAGING AND PLAYING ASSETS

Ingesting Assets from the .NET SDK

Obtain a CloudMediaContext• Gives you access to all objects and APIs

Create an asset (IAsset)• A collection of media files

Create a file (IAssetFile)• A single file within an asset

Create an access policy and locator• Determines ACL for asset and provides a URL

for upload

Encoding Assets from the .NET SDK

Obtain a media processor (IMediaProcessor)• Media processors can encode and package assets

Create an encoding job (IJob)• A job is a set of tasks for Media Services

Add tasks to the job (ITask)• E.g., encode WMV file for Apple HLS• Tasks have input assets and output assets

Monitor job progress until it completes

Delivering Assets from the .NET SDK

Locate the output asset for a job

Create an access policy and locator

Generate URLs• For progressive download• For streaming (IIS/HLS)

Optional: Enable CDN• For progressive download (blob storage)• For streaming origin server

DEMOUploading and encoding an asset from the .NET SDK

Playing Progressive Download Assets

• For progressive download in browsers that support HTML5 video, use the <video> element

<video width="640" height="480" controls> <sourcesrc="@Html.Raw(Model.Mp4SourceUrl)"

type="video/mp4" /></video>

Playing IIS Smooth Streaming

• For PC and Mac delivery of IIS Smooth Streaming, use the Silverlight Smooth Streaming SDK– Sample player available on CodePlex– http://playerframework.codeplex.com/

<object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">

<param name="source" value="/Content/SmoothStreamingPlayer.xap"/>

<param name="InitParams"

value="mediaurl=@Model.SilverlightStreamingUrl"/></object>

Server-hosted Silverlight player

Parameters for player

Playing HLS In-App on iOS

• The iOS MediaPlayer framework natively supports Apple HLS URLs

self.player = [[MPMoviePlayerController alloc]initWithContentURL:[NSURL

URLWithString:...]];self.player.scalingMode = MPMovieScalingModeAspectFill;self.player.controlStyle = MPMovieControlStyleDefault;[self.view addSubview:self.player.view];[self.player play];
