2. With Windows Azure Media
Services, you can upload, manage,
encode, and stream your media to a
variety of devices on a cloud
scale.

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

4. … 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 …

5. … 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.

11. Managing and Playing
Assets

12. 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

13. 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

14. 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

15. DEMO
Uploading and encoding an asset from the .NET SDK

16. Playing Progressive Download Assets
• For progressive download in browsers that support
HTML5 video, use the <video> element
<video width="640" height="480" controls>
<source src="@Html.Raw(Model.Mp4SourceUrl)"
type="video/mp4" />
</video>

17. 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

18. 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];
