TechEd NZ 2014 - DEV312 - James Carpinter Video is transforming how organizations create compelling customer experiences and how they share knowledge and engage with employees. The reality is challenging though: how do you provide a first class experience on an ever-expanding range of browsers and devices, and all while managing cost? Come see how Azure Media Services allows developers to build sophisticated media workflows to ingest, encode, encrypt, package and deliver any content, at any time, in any place and on any device.

AgendaOpportunities & ChallengesDelivering mediaConsuming mediaFuture
Opportunities & Challenges
OpportunitiesImprove customer & employee engagementMore compelling experiences to create brand awareness, inform customers and drive actionHelp onboard new hires, share best practice, broadcast communications from leadershipAnother component of creating compelling modern user experiences
Build your media empireMassive on-demand capacity without the upfront costReach billions of devices across the globe
ChallengesDeliveryIE, FF, Chrome, Safari, iOS, Android, Windows, Windows Phone, Xbox, Flash, Silverlight, … Recorded content vs. live streams, fixed vs. adaptive encoding, …
ReturnEnabling business models to monetize contentReducing costs to create a positive ROI
Media itselfIt’s hard: transcoding, trans-muxing, streaming, codecs, live channels, …
Delivering media
‘any content, at any time, in any place and on any
device’
Media ServicesOptimal cloud workloadScale on-demand with no upfront costsBuilt on a reliable and available platformGlobal reach through Azure DCs and CDNCompliance with security standards & best practicesCost advantages through economies of scale and usage-based pricing
Proven at Sochi 20146,000 hours of HD streaming to 5 broadcasters across 22 countries204 live streaming channels100TB storage and 500 billion storage transactions2.1 million viewers on a single authenticated stream (US vs. Canada ice hockey)

Working with Media Services1. PortalBasic management functionality
2. PowerShellProvisioning functionality only at this point
3. REST APIAvailable to any platform with auth token issued by ACSOData-based so follows predictable patterns for interaction
4. SDK: .NET (via NuGet), Java, PHP, Node.jsLight native wrappers over the REST APIExposes key entities; no hints on how they wire together

From end-to-end
1. IngestBroad range of source formatsIncluding codecs like H.264, MPEG-1/2/4, VC1, WMV
One destination: Azure Blob StorageProbably best to avoid browser-based uploads in the Azure PortalSDK provides helpers for efficient multi-threaded uploads directly to storageOr use your favourite tool; consider ExpressRoute or Aspera if you’re seriousMedia Services account is paired to one or more storage accounts
Security is a priority*Encrypt content before uploadEncrypt content at restUpload over an SSL connection
2. EncodeTranscoding mezzanine file to suit your scenarioChange codec, resolutions, bitrates, stitch video together, overlay video, …CPU intensive work to decompress, analyze and re-compress video‘Building a toy’
Fixed vs. adaptive bitratesFixed forces client to choose bitrate and then download video file progressivelyAdaptive allows client to dynamically adjust bitrate during playback
On demand vs. reserved unitsReserved provides more predictable performance and parallel processing

3. PackageTrans-muxing to suit your scenarioTaking encoded video and placing it in different containersNot particularly CPU intensive; no raw video is unchanged‘Gift wrapping a toy’
Static packagingCreate packaged files for each supported protocol
Dynamic packagingFrom an adaptive bitrate MP4, Media Services can deliver SS, HLS & DASHRequires origin units but reduces storage cost / complexity

4. EncryptNot always requiredDepends on your scenarioHowever, Media Services distributes via HTTP (not HTTPS)Encryption is content protection
OptionsAES encryption: symmetric keyPlayReady DRM: magic; supports rights mgmt. but requires more infrastructure
Do you trust me?Yes – AES key sent to users ‘in the clear’; great option for internal contentNo – PlayReady DRM sends key with protection; great option for protecting broadly distributed content
5. DeliverCreate locatorsTime limited URIs that point to assetsNot access control
Fixed bitrateDirect from Azure Blob Storage
Adaptive bitrateFrom Azure Media Services origins; applies dynamic packaging/encryptionCapacity reserved in 200Mbps chunks
Consider CDN for large scale distributionAll content delivered over HTTP so can be effectively cached in network

Consuming media
WebHTML5 videoSupported by ~75% of the market; all major browsers support MP4Progressive download / Fixed bitrate
MPEG-DASHPart of W3C Media Source ExtensionsEnables adaptive streaming Early stage (IE11, Chrome, FF*)
PluginsNobody likes plugins any more (battery life, patching, mobile browsers, …)Consider when targeting desktops & adaptive bitrate, DRM or advertisingFlash and/or Silverlight support Smooth Streaming
