Debugging Your Custom IIS Transform Manager Task

Debugging Your Custom IIS Transform Manager Task | Video Breakthroughs | Scoop.it

During an initialization phase, the ITask interface provides your custom task with injected dependent objects, see here for more details on these objects. One challenge while writing a custom ITask implementation is debugging your task with real-time injected values. One approach is to have your debugger launch a finished or failed job in a similar environment as the IIS Transform Manager would.

 

Here are the high level tasks to achieve this:

- Run and locate a job instance

- Identify the program and arguments to execute

- Setup the working environment

- Run the command under your debugger

HTTP Streaming in Varnish

HTTP Streaming in Varnish | Video Breakthroughs | Scoop.it

How HTTP streaming works with Varnish

 

All of the implementations we've seen have the following in common. You have a H264 video stream, either linear (live) or a big file, usually acompanied by AAC audio. You have a stream fragmentor, which chops the stream into segments, giving each segment a separate URL. The client then requests each segment in a separate requests. The notion of the stream is superimposed through pointers in each segment or by maintaining some sort of playlist. It is up to the client to join the segments toghether in a smooth manner.

 

Look for release 3.0.2s !

What is MPEG DASH?

What is MPEG DASH? | Video Breakthroughs | Scoop.it

MPEG DASH is the latest hot topic in the online video space. Here we break down what it is, and what its implications might be for video delivery in the future.

 

MPEG DASH (Dynamic Adaptive Streaming over HTTP) is a developing ISO Standard (ISO/IEC 23009-1) that should be finalized by early 2012. As the name suggests, DASH is a standard for adaptive streaming over HTTP that has the potential to replace existing proprietary technologies like Microsoft Smooth Streaming, Adobe Dynamic Streaming, and Apple HTTP Live Streaming (HLS). A unified standard would be a boon to content publishers, who could produce one set of files that play on all DASH-compatible devices.

 

The DASH working group has industry support from a range of companies, with contributors including critical stakeholders like Apple, Adobe, Microsoft, Netflix, Qualcomm, and many others. However, while Microsoft has indicated that it will likely support the standard as soon as it’s finalized, Adobe and Apple have not given the same guidance, and until DASH is supported by these two major players, it will gain little traction in the market.

OTT video delivery : A properly engineered network decreases customer churn

OTT video delivery : A properly engineered network decreases customer churn | Video Breakthroughs | Scoop.it

There is a growing effort by broadcasters to make regular TV content available online. For example, the BBC has developed the BBC iPlayer and the bbc.co.uk website to support replication of most BBC broadcast material. The service has been outstandingly successful: 79.3 million requests were serviced in October 2009. NBC coverage of the 2010 Winter Olympics included live and recently recorded content, complete with commercials.


Whenever there is the possibility of a large or dynamic viewer audience, a reliable CDN is required. CDNs once only used to replicate website content around the world. Now, they have expanded dramatically to handle streaming media. Research and markets estimated the value of CDN services for 2008 at $1.25 billion, up 32 percent from 2007. Top CDNs include Akamai, Mirror Image Internet, Limelight Networks, CDNetworks and Level 3. Streaming media services must deal with content collected from disparate sources and distributed to a growing number of devices.

BBC R&D White Paper : Enabling and Enriching Broadcast Services by Combining IP and Broadcast Delivery

BBC R&D  White Paper : Enabling and Enriching Broadcast Services by Combining IP and Broadcast Delivery | Video Breakthroughs | Scoop.it

This paper explores the opportunities and challenges of supplementing television broadcast channels with additional content using IP delivery. It looks at the way in which the additional material could be resynchronised with the broadcast content and what level of accuracy is required by different types of material.

 

It focuses on the use case of an alternative soundtrack to provide improved intelligibility for viewers who have difficulty understanding speech when presented with background sound. It then goes on to describe our demonstration system and discusses the opportunities for further research into hybrid delivery and the way it could enable a richer broadcasting landscape.

CFF: One Format to Rule Them All?

CFF: One Format to Rule Them All? | Video Breakthroughs | Scoop.it

The move towards MPEG DASH and the fragmented MP4 (fMP4) common file format may finally offer DVD-like interoperability for web video.

 

Since the early days of online video, various battles have been waged among competing video codecs and formats, but those battles were merely indicative of the larger struggle between those who support a common file format for all online video delivery and those who support proprietary formats. The most recent push for a common file format is coming from proponents of MPEG DASH, and if the standing-room-only crowd at an MPEG DASH panel at Streaming Media West earlier this month is any indication, its time may have come.

 

UltraViolet, which uses both a common file format and common encryption, is supported by six major studios and the seventy-member Digital Entertainment Content Ecosystem (DECE) as a way to deliver premium content such as movies on both physical media (discs) and online (digital downloads). As described in detail in a "What Is...?" article by Jan Ozer, MPEG DASH is a way to standardize manifests (called Media Presentation Descriptions or MPDs) that is moving through the ISO ratification process piece by piece.

The trials and tribulations of HTML video in the post-Flash era

The trials and tribulations of HTML video in the post-Flash era | Video Breakthroughs | Scoop.it

Adobe reversed course on its Flash strategy after a recent round of layoffs and restructuring, concluding that HTML5 is the future of rich Internet content on mobile devices. Adobe now says it doesn’t intend to develop new mobile ports of its Flash player browser plugin, though existing implementations will continue to be maintained.

 

Adobe’s withdrawal from the mobile browser space means that HTML5 is now the path forward for developers who want to reach everyone and deliver an experience that works across all screens. The strengths and limitations of existing standards will now have significant implications for content creators who want to deliver video content on the post-flash Web.

After releasing his clear post on DASH today (http://bit.ly/seRUFr), Jan Ozer is talking back on issues raised by the dual norms M2TS/fMP4 of DASH and the doubts raised by lack of clear positions of Adobe - and its explicit alliance with Microsoft to bash Apple old-school approach. On top of this, DASH is not royaltee-free for the moment, so the future of this normative effort is quite unclear at this stage...

A few notes that didn't make it into the latest StreamingMedia article:

MPEG-DASH will never define a codec, but with DASH-264 there's a move to use an H.264 codec in an MP4 container with a common file format (CFF) and common encryption (CENC).... There's also a possibility of adding DASH-264 into the HTML5 standard, since W3C requires a codec to be considered in HTML5 but MPEG-DASH itself is codec agnostic.

FIMS and SOA : New architectures provide business agility

FIMS and SOA : New architectures provide business agility | Video Breakthroughs | Scoop.it

Broadcasters no longer have the monopoly on the delivery of A/V entertainment to the home. In the fiercely competitive world of media and entertainment, companies have to deliver more versions and formats, but without increasing their costs. A channel is now expected to have a Web presence, as well as mobile and tablet versions of their content.


Organizations like the EBU and Advanced Media Workflow Association (AMWA) are promoting the service-oriented architecture (SOA) as a route to provide the interoperable media services that can serve the new business requirements.


For the seasoned video engineer, the world of SOA introduces terms and concepts that at first encounter seem foreign and more suited to the IT specialist. As video processing migrates to the file domain, there is no option but to become familiar with what at first sight may appear alien.


Broadcast systems have evolved around the imposed workflow of the serial processing steps of videotape operations. Over time, many processes have moved from dedicated hardware boxes with SDI in and out to software applications on a network. A typical broadcast operation is now a hybrid of SDI and IP connections.


In many cases, the workflow remains as the original tape-based flow. Over time, other applications like asset and workflow management are layered over the entire process chain. The system has grown by accident, not by design, and become a web of custom or proprietary interfaces linking the many applications.


Sure it works, it was designed that way, but when the time comes to replace a component part — say the playout automation — the inflexibility of the system rapidly comes apparent. The parts of the system are linked by a web of custom APIs, often restricted to a specific release of a specific software application. It is just not possible to swap out the automation for the latest product without attending to the web of interfaces.


To meet the demands for new services to the public, the broadcaster must add facilities for a mobile news service, a 3-D channel and interaction with a social media website. Along comes CES and some new consumer device to consume content. How do you add support for this new device? Will it mean more custom interfaces or more special workflow applications? The EBU and AMWA are developing a Framework for Interoperable Media Services (FIMS), which aims to provide a new technology platform that leverages current IT practices, like the use of the SOA, to provide business agility and to control costs.

The changing nature of media consumption has transformed the broadcast business model. Broadcasters are delivering a proliferation of media-related services to broader audiences via additional outlets and platforms. As the number of offerings has grown, however, average revenue per service has dropped. In a tough economic climate, and with IPTV and VOD services gaining ground, broadcasters face constant competitive and price pressures. And, while trends and evolving technologies continue to shape products, broadcasters are finding that it's more important than ever that their established channel playout operations run as efficiently as possible.
