Build end-to-end video experiences with Azure Media Services

Editor's Notes

1. 2013 we started to see TV threatened by streaming TV Provides a way better viewing experience
2. Azure Media Services is a platform-as-a-service that enables you to build customizable media workflow; you could upload, encode, encrypt, package, and deliver video content to multiple platforms and devices.
3. Built on top of Microsoft Azure Media Services is PaaS Offers developers a REST API to access the service Windows Azure Portal is a “Build-On” partner Videos can be delivered through a CDN Client SDKs allow developers to build on various devices and platforms for free
4. Ingest content from local disk to Azure Blob storage
5. By default you will share the encoding through a queue
6. You can also provision your own Encoding Reserved Units to run multiple jobs at once Supports standard codecs like H.264 and AAC-LC Smooth Streaming is an IIS Media Services extension that enables adaptive streaming of media to clients over HTTP PlayReady is a content protection technology from Microsoft that includes encryption, output protection and Digital Rights Management (DRM)
7. Microsoft provides an origin server so customers can watch the content Guaranteed bandwidth when you have your own box (think about viral videos)
8. See /Demo1 folder from readiness kit for steps of this demo. To watch a recorded version of this demo see http://channel9.msdn.com/Events/Build/2014/3-610?#time=9m24s Upload, encode and playback in portal 1. In the management portal show the +New entry point for creating media services 2. Flip to existing media services instance 3. Click into the media service, select the Content tab 4. Press Upload in the command bar 5. Select a file and click ok 6. Once source video is uploaded, click encode in the command bar and do a rename 7. Show the Job tab to show that it is encoding 8. Encoding tab is where you can show the Reserved Capacity 9. Select Preset drop down Playback via HTML5 (IE/Chrome/Safari) 10. Once encoding job is done, click Publish in the command bar 11. Once published click Play in the command bar
9. Portal is not the only way to work with Media Services
10. Traditionally you would encode and package your content for multiple formats to be stored on the server Dynamic packaging means after encoding the origin server will package the content on the fly based on need Save time and money by not needing intermediate packaging step Save money in storage costs as only need one copy of encoded video Must have at least one reserved streaming unit Dynamic Adaptive Streaming over HTTP (DASH), also known as MPEG-DASH, is an adaptive bitrate streaming technique that enables high quality streaming of media content over the Internet delivered from conventional HTTP web servers
11. This demo is available in the /Demo2 folder of the readiness kit. 1. Pre-reqs: Follow steps in top of program.cs 2. Delivery Refer to recorded version of demo - http://channel9.msdn.com/Events/Build/2014/3-610?#time=15m34s 3. Note: Instead of using the custom website player. once encoding and publish is done you can watch the video directly from within the portal on the Content Tab click play You need to have at least 1 reserved streaming unit to enable dynamic packaging!
12. Man-in-the-middle attack is eavesdropping on videos
13. Two options: AES clear key and Digital Rights Management (DRM) For both, when the video is moved from the cloud to your player it is encrypted with AES AES clear key is on client side; client can see the key so you must trust your client DRM means neither the key nor the content are exposed on the client DRM model is used enforce a 48 –hour or 3-time viewing on a rented movie
14. AES is lower cost versus DRM DRM needs DRM SDK on player DRM SDK is not free Some platforms might not have a DRM SDK
15. HTTP Live Streaming (also known as HLS) is an HTTP-based media streaming communications protocol implemented by Apple Inc. as part of their QuickTime, Safari, OS X, and iOS software
16. Only partner ezDRM for a PlayReady server Smooth Streaming is an IIS Media Services extension that enables adaptive streaming of media to clients over HTTP PlayReady is a content protection technology from Microsoft that includes encryption, output protection and Digital Rights Management (DRM)
17. Example of AES for Enterprise is Office 365 Authenticated through A.D. All videos are encrypted thorough AES
18. Dynamic Adaptive Streaming over HTTP (DASH), also known as MPEG-DASH, is an adaptive bitrate streaming technique that enables high quality streaming of media content over the Internet delivered from conventional HTTP web servers HTTP Live Streaming (also known as HLS) is an HTTP-based media streaming communications protocol implemented by Apple Inc. as part of their QuickTime, Safari, OS X, and iOS software
19. Submit a URL to Microsoft of the live stream You must encode the stream as they do not have live encoding; so only smooth streaming as input Microsoft provisions a channel with the ingestion It’s the forwarded to Preview module to monitor it or add voice over It then goes to Program module to provide it to the users It is written to Blob Storage immediately so it can be VOD
