Netflix open sources tool for making cloud services play nice

Netflix open sources tool for making cloud services play nice | Video Breakthroughs | Scoop.it

Netflix, it seems, is to cloud computing what Google and Facebook are to distributed systems, generally. Today, Netflix has open sourced its latest technology for keeping its cloud-hosted applications running — a set of libraries, called Hystrix, that is designed to manage interactions between the myriad services that comprise the company’s distributed architecture. If you’re building service-oriented architectures in the Amazon Web Services cloud, it might be worth a look.

 

Hystrix actually stems from earlier work to add resilience to the Netflix API, the means by which many customer-facing applications access the services they need to run. As Christensen explained in a February 2012 blog post, services are distributed across thousands of instances in AWS, and if there are problems with those services — such as high latency or failed connections between them — it can wreak havoc on the Netflix API and seriously affect the performance of all the applications that depend on it.

HbbTV 2.0 to go mainstream in 2016

HbbTV 2.0 to go mainstream in 2016 | Video Breakthroughs | Scoop.it

The first commercial deployments of version 2.0 of the hybrid broadcast/broadband standard HbbTV are now likely to surface in the second half of 2015, with mainstream adoption taking place the year after, according to the HbbTV Association – currently holding its annual Symposium in Paris.


Proposed features for HbbTV 2.0 include improved support for HTML-5, push-VOD, ad insertion, HEVC video and MPEG-Dash – plus the introduction of companion screen app-launching and synchronisation. 

It had been hoped the specification would be nailed down around half-way through 2014, but Kirk Edwardson, co-chair of the HbbTV Marketing Group, said that 2.0 was still moving through ratification and final approval. 


“Late this year/Q1 next year, we should be into final ratification, and starting then to turn that over to commercial suppliers […] to start to implement,” he said. “So I think we should start seeing our first 2.0 services and devices in the second half of 2015. 2016 is probably where you’ll see it really blossom.”

HTTP Adaptive Streaming with GStreamer

HTTP Adaptive Streaming with GStreamer | Video Breakthroughs | Scoop.it

Let’s talk a bit about HTTP Adaptive streaming and GStreamer, what it is and how it works. Especially the implementation in GStreamer is not exactly trivial and can be a bit confusing at first sight.


If you’re just interested in knowing if GStreamer supports any HTTP adaptive streaming protocols and which you can stop after this paragraph: yes, and there are currently elements for handling HLSMPEG DASH and Microsoft SmoothStreaming.

The MPEG-DASH Superguide

The MPEG-DASH Superguide | Video Breakthroughs | Scoop.it

DASH’s Time Has Come 

By now, you’ve probably read enough to understand what DASH is and why it’s important. But let’s boil it down to the most important points: DASH is an adaptive bitrate streaming technology for delivering multimedia—i.e., video. It’s a codec- agnostic technology designed to partition and deliver congruent piecesofamultimediafiletoaclient,usingHTTP. Alongwith network conditions and other variables, the receiving device (such as a smartphone, tablet, set-top box, smart TV, or computer) dictates which “chunks”—each of which contains a different resolution and bitrate—to deliver to ensure uninterrupted play of the file as a whole. Of course, adaptive bitrate (ABR) streaming has been around for a while. If you ever watched a cat playing a piano and it got fuzzy for a few seconds, you experienced a version of ABR. But was it DASH doing the heavy lifting? Almost certainly not. That’s changing...

BroadThinking 14: Forget Multiscreen, We're Heading Towards ONE Screen

BroadThinking 14: Forget Multiscreen, We're Heading Towards ONE Screen | Video Breakthroughs | Scoop.it

This year the EBU BroadThinking Conference was sounding like a holistic swirl, a milestone in the trend of technology to define sets that are greater than the sum of their parts, through creative evolution. « Where Broadcast Meets BroadBand », you get some interesting fusion effect occurring and diluting the traditional boundaries of the screens, with the handheld devices being part of the big screen experience or extending it rather than trying to scalp it, in an environment where all the devices converge towards a restricted set of standards rather than tracing their own line.


While we by default think that standardization kills creativity, events like BroadThinking show that it’s the opposite: if we gather energies to solve common problems together, we can both come up with a more evolved solution and concentrate on what’s important past the pixel grid: the user experience, so consistent across screens that you forget there’s more than one screen involved.

IBC 2014 : 4K down the road

IBC 2014  : 4K down the road | Video Breakthroughs | Scoop.it

A l’IBC en 2012 et 2013, la 4K était surtout présente dans l’amont de la chaîne de valeur, avec les caméras et systèmes de post-production de programmes de stocks. L’année dernière étaient apparus les premiers outils pour réaliser des programmes de flux (TV en direct) et avaient été menées les premières expériences de captation en live dont Roland Garros. Les premières expérimentations d’encodage et de diffusion satellite avaient démarré en 2012, mais sur des programmes de “stock”.


En 2014, c’était au tour d’un grand nombre d’acteurs côté réception et box de faire des démonstrations de solutions 4K. Roland Garros n’a plus seulement été capté en 4K mais également diffusé, et sur trois tuyaux (à titre expérimental) : en IP, en satellite et en TNT (DVB-T2 via la Tour Eiffel). Année paire oblige, la 4K a aussi été largement expérimentée aux JO de Sotchi ainsi que pendant la Coupe du Monde de Football au Brésil. Les professionnels fourbissent maintenant leurs armes pour être prêts pour la prochaine année paire, 2016 et notamment pour les Jeux Olympiques à Rio de Janeiro.


Les premiers projets 4K concrets commencent à voir le jour chez les opérateurs les plus innovateurs. Vodafone va ainsi lancer sa première offre de TV payante 4K début 2015 en Allemagne. Si les box à venir sur le marché français ne seront probablement pas encore 4K en 2014-2015 (chez Bouygues Telecom, Orange et Free), les générations suivantes sauteront sans doutes le pas. On attend toujours de voir qui sera le premier à dégainer ? Free ou Canal+ voire Orange ? C’est une question qui mêle : la capacité d’innovation, la volonté de différentiation des acteurs, le calendrier de livraison des chipsets 4K pour set-top-boxes et des considérations économiques évidentes. Les box prévues pour courant 2015 ont plus de chances d’être 4K que celles qui sont prévues pour 2014 voire début 2015.

Introducing: Azure Media Indexer

Introducing: Azure Media Indexer | Video Breakthroughs | Scoop.it

The Internet was designed around text-based documents, and as such, has mature infrastructure to encourage and enable the search and discovery of text across the entire web. Video files, on the other hand, are not natively “searchable”, and usually require complex classification systems primarily powered by massive amounts of manually-tagged metadata. But what if there was a way to extract this kind of meaningful metadata automatically? Azure Media Indexer is a media processor that leverages natural language processing (NLP) technology from Microsoft Research to make media files and content searchable by exposing this meaningful metadata to the end-user automatically in the form of a keyword file (XML), a set of closed caption files (SAMI/TTML), and a powerful binary index file (AIB).

HTML5 EME is not a DRM standard. :: not.even.code.

HTML5 EME is not a DRM standard. :: not.even.code. | Video Breakthroughs | Scoop.it

Probably the hottest thing the W3C is working on right now is their Encrypted Media Extension Working Draft. The EME draft is widely talked about as "the DRM standard for HTML5", but this is not truly what it's content covers. I'll look at what it is, why it's not a great idea, and some implications of its approval, were it to be approved.

It's possible to tell what's actually covered by the W3C's draft by carefully examining its title; the second word - "media" - is the key. Your average layman might assume that this refers to media in the general sense (and its oh-so-natural wont for encryption); whereas in fact, it refers very specifically to HTML5's media elements. You might know them as <audio> and <video>. The standard specifies some funky extensions to their DOM/Javascript API, based around cryptographic key management. There is almost nothing here about interesting DRM technology, but there are some warnings that it will introduce yet another way for advertisers to track you. Huzzah.

RGB Networks Aims to Change Video Industry with Pioneering Open Source Software Transcoder Initiative

Called ‘Ripcode Transcoder’, after the company Ripcode, which was acquired by RGB Networks in 2010 and which originally developed TransAct, the new, cloud-enabled software transcoder will provide RGB Networks’ customers with greater control, integration and flexibility in their video delivery workflows. In a pioneering move, and harnessing the industry momentum toward developing cloud-based solutions, RGB Networks is actively welcoming operators and vendors to be part of a community of contributors to the open source project.


The intended feature set of the open source Ripcode Transcoder will include:

  • Both Linear (live) and Video on Demand (VOD) transcoding
  • Full cluster management, load balancing, and failover
  • Linear and VOD transcoding of MPEG2, H.264, H.265, AAC, AC3, and other industry leading video and audio codecs
  • File-to-File watch folders
  • Full reporting and logging of events
  • Commercial-grade GUI
  • RESTful APIs

Unlike other open source projects, an open source transcoder is more difficult to release due to built-in professional codec licensing. RGB Networks will release Ripcode Transcoder with only the codecs that can be legally used with open source software. Additionally, in order to facilitate use of the transcoder in professional environments that require licensed, third party codecs and pre/post processing filters, the Ripcode transcoder will include a plug-in framework, that will allow use of best-of-breed codecs and filters.

Working with Brightcove Video Cloud and MPEG-DASH

Working with Brightcove Video Cloud and MPEG-DASH | Video Breakthroughs | Scoop.it

Brightcove now supports transcoding video into the MPEG-DASH format. Support is also available for MPEG-DASH encrypted with Common Encryption, allowing multiple DRM systems to playback a single source asset. This topic provides an overview of the steps required to publish and play DASH content through Video Cloud.

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. Similar to Apple's HTTP Live Streaming (HLS) solution, MPEG-DASH works by breaking the content into a sequence of small HTTP-based file segments, each segment containing a short interval of playback time of a content that is potentially many hours in duration, such as a movie or the live broadcast of a sports event. The content is made available at a variety of different bit rates and as the content is played back by an MPEG-DASH client, the client automatically selects from the alternatives the next segment to download and play back based on current network conditions.

DASH Live Streaming with Azure Media Service

DASH Live Streaming with Azure Media Service | Video Breakthroughs | Scoop.it

This article focuses on the live streaming DASH features enabled by Azure Media Service, and how they can be used to deliver live and video on demand adaptive streaming to Web browsers and new devices of all types, which are adding support for the DASH standard.  DASH live streaming is now available for public preview, and will graduate to “general availability” with normal service level agreements after the preview period.


DASH output is a runtime option for all live and VOD streaming from Azure Media Services.  A player can request a DASH Media Presentation Description manifest and compatible ISO Base Media File Format “Media Segments” just by including a DASH format tag in each URL request.  The same files or live stream can be delivered in Microsoft Smooth Streaming, Apple HLS, or Adobe HDS by indicating any of those formats in the URL format tag.  This enables the introduction of DASH to new browsers and devices while maintaining compatibility with legacy players and formats.  The ability to dynamically package media segments in realtime is essential for low latency live streaming, as well as efficient multiplatform support.
