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...

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.

Will MSE/EME/DASH Lead to Simpler Workflows? Don't Bet on It

Will MSE/EME/DASH Lead to Simpler Workflows? Don't Bet on It | Video Breakthroughs | Scoop.it

What the online video industry needs is simple standards for reaching all viewers. But when have standards ever simplified online video?


Proprietary technologies are inherently bad in the video space, except when they’re not. Standards inevitably simplify matters, except when they don’t. So it is with Flash, and its obvious successors, the Media Source Extensions (MSE), Encrypted Media Extensions (EME), and Dynamic Adaptive Streaming via HTTP (DASH). 


MSE/EME/DASH are the standards that will enable web publishers to replace Flash in their playback architectures. MSE eliminates two of HTML5's most critical limitations by bringing standards-based adaptive streaming and live delivery to HTML5 browsers and devices. EME brings a single encryption API to HTML5 browsers, providing digital rights management (DRM), addressing another former deficit. DASH is the standards-based file format that will actually deliver the streams. The vision is one set of cache-friendly streams in DASH format that can play on any MSE/EME-compatible computer or device, which will replace the two streams most producers create today for Flash and HLS playback.

Adobe Primetime Support for MPEG-DASH

Adobe Primetime Support for MPEG-DASH | Video Breakthroughs | Scoop.it

For those of us working to develop MPEG-DASH, Apple’s recent support of the W3C’s Media Source Extensions (MSE) API in Safari on OS X Yosemite is great news.  MSE and DASH have a complementary relationship, and expanded support for MSE will make it much easier for publishers to adopt DASH.


While MSE itself is designed to be media container format neutral, one of the primary container format recommendations made in the specification is compatible with the ISO Base Media File Format (ISO BMFF)“fragmented MP4” profile of MPEG-DASH.  At this time, MSE implementations in most desktop browsers (Chrome, IE, Safari) are available and support the ISO BMFF container.  Firefox is also working on compatible implementations, which are already partially available in their development branches.

Diving into ultra-low latency for live using MPEG-DASH

Low latency with HTTP-streaming (segment-based) technologies is a challenge. In particular MPEG-DASH is gaining adoption among international industry consortiums such as DVB with DVB DASH or ETSI with HbbTV 2.0 (not published yet), with a growing focus on live use-cases. For such applications, latency is a concern.

 

In this article, we will show you how the GPAC team studied the impact on the overhead of HD streaming with very low latency using MPEG-DASH and demonstrated that overhead on the transport side is negligible, in the order of 1%. At 1% overhead, we could demonstrate a 240ms latency. With such a low latency, interactive or bidirectional applications such as video conferencing or live streaming with voting become possible.

 

Of course such low latency can only be safely reproduced in local network conditions. Yet it shows that the latency is not due to the MPEG-DASH technology but rather to the network conditions. It also shows that a few technical choices can dramatically reduce the latency.

All the tools used for this demonstration are available as free software.

Why the Broadcasting Industry Should Get Behind DASH Adoption

Why the Broadcasting Industry Should Get Behind DASH Adoption | Video Breakthroughs | Scoop.it

How is DASH different from competing video standards. It's open, and for broadcasters that's a big factor. At the recent Streaming Media East conference, Jeff Tapper, chief architect at Digital Primates, taught attendees how to build a DASH player, and also why DASH stands apart.

 

"The real key differentiator of DASH, as opposed to any of the other HTTP streaming formats, is it's an open standard. HLS, HDS, Smooth Streaming: They're all owned by one company," Tapper said. "Some of them have becomede facto standards on their own, but the more I work with broadcasters and people who are used to open standards like AM and FM and UHF and VHF -- these are standards that everybody agrees on. The broadcasting world loves standards."

YouTube now defaults to HTML5

YouTube now defaults to HTML5 | Video Breakthroughs | Scoop.it

Four years ago, we wrote about YouTube’s early support for the HTML5 <video> tag and how it performed compared to Flash. At the time, there were limitations that held it back from becoming our preferred platform for video delivery. Most critically, HTML5 lacked support for Adaptive Bitrate (ABR) that lets us show you more videos with less buffering.

Over the last four years, we’ve worked with browser vendors and the broader community to close those gaps, and now, YouTube uses HTML5 <video> by default in Chrome, IE 11, Safari 8 and in beta versions of Firefox.

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.”

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.

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.

Even though users will be able to let NPAPI plug-ins run by default in January, we encourage developers to migrate of off NPAPI as soon as possible. Support for NPAPI will be completely removed from Chrome in a future release, probably by the end of 2014.


The ability to adapt media streaming to an individual consumer is critical in delivering high-quality content to a large audience. In the past this capability has been provided by technologies such as Silverlight’s smooth streaming and Quicktime’s HTTP live streaming. The Media Source Extensions to the HTML media element provide the capability to adapt a stream to an individual consumer on the modern web. Html5rocks has put together a great example of how to use the Media Source Extensions to implement some of these common use cases.

Improving the Quality of Experience with MPEG-DASH Ultra HD

Improving the Quality of Experience with MPEG-DASH Ultra HD | Video Breakthroughs | Scoop.it

How can publishers ensure that their viewers are getting a TV-like experience with MPEG-DASH video? At the recent Streaming Forum conference in London, experts from Qualcomm and Bitmovin explained the finer points of QoE for DASH.

 

"How can the DASH standard or standardized formats have to increase the quality, once there is some kind of metrics or logging functionality at the client that gives you means to communicate to another instance -- a logging server or whatever -- what's going on in the client side?" asked Christian Timmerer, CIO for Bitmovin. "In DASH there is an Annex D which is a normative definition of semantics for these metrics according to different observation points. If you have the DASH access client -- that basically is the one that issues the HTTP request -- and gets the responses and hands that over to what we call here a DASH-enabled application, which then in the end feeds into a display for rendering purposes or whatever."

HTTP/2.0 and DASH: Planning Tomorrow's Improved Video Delivery

HTTP/2.0 and DASH: Planning Tomorrow's Improved Video Delivery | Video Breakthroughs | Scoop.it

HTTP traffic has grown extensively driven by the immense growth of multimedia traffic. Nowadays, it could be seen as the protocol to deploy new services and applicationsand it is also heavily used by the industry, due to the fact that it provides advanced features for modern internet architectures.

 

It is a content centric protocol that decouples names from addresses through DNSIt provides caching elements and middle boxes as reverse and forward proxiesIt enables scalable and flexible content deployment with content distribution, already leveraged by Content Distribution Networks (CDN)

 

However, there is room for improvement as many services are still using HTTP/1.0 which was specified in May 1996, or are not using all the features of HTTP/1.1, such as persistent connections or pipelining. For example, already deployed HTTP streaming solutions such as Microsoft Smooth Streaming, Apple HTTP Live Streaming, and Adobe Dynamic Streaming do not use HTTP/1.1 pipelining with persistent connections, which could increase the streaming performance by up to 30 percent. Unfortunately, there are not many proxies that support HTTP/1.1 pipelining with persistent connections, due to the Head-of-Line (HoL) blocking problem where one pending response could possibly delay a range of other responses. The problem is that the proxy has to send in-order responses, which means that earlier arriving out-of-order responses will be blocked until the response that causes the HoL blocking arrives.
