Kaltura Community Edition Case Study – StreamUK Launching Enterprise Grade Kaltura CE based Video Platform.

by Duncan.Burbidge

StreamUK Logo

This is a guest post by Duncan Burbidge, Co-Founder and CEO of StreamUK, a UK based webcasting and digital media company.


StreamUK was founded in 2001 to provide digital media solutions and back then you did everything yourself.  After 7 years of trying to match the increasing pace of technological development, the decision was taken to investigate options for StreamUK’s main online video platform (OVP).

In 2008, various options presented themselves, including partnerships with the likes of Brightcove, taking investment to re-develop our own OVP or working with an open source variant.  After trialling and modelling these approaches, it was decided that the latter (adopting an open source solution) was the most promising for three reasons:

  • Culturally – we, and more importantly our clients, needed control of their features from Europe;
  • Practically – we have huge value to contribute to the solution from a decade of accumulating knowledge at code, CDN and video levels;
  • Temporally(!) – we needed to get to market faster than we could develop from scratch.

StreamUK joined the global Kaltura community of experts (which at November 2011 stands in excess of 20,000) and began to contribute to the codebase of the Kaltura version 1.5 release.  As we became more familiar with the project, we became more impressed by it and in early 2009 we recruited a team of four full-time php-Zend developers to build on the framework, planning for a late 2010 release.

Adobe’s Flash Focus Change Followup – The Flex SDK

by Zohar Babin

Following this week’s announcement by Adobe to halt development of Flash for mobile browsers, the Adobe Flex product managers have just announced that they will be making significant changes in the Flex SDK –

“…we are planning to contribute the Flex SDK to an open source foundation…”
“… Flex SDK feature development will continue under a new governance model…”

The Flex SDK was Open Source for a few years now, why then this sudden need to re-structure its governance model, why now?

“In the long-term, we believe HTML5 will be the best technology for enterprise application development. We also know that, currently, Flex has clear benefits for large-scale client projects typically associated with desktop application profiles.”

“…In fact, many of the engineers and product managers who worked on Flex SDK will be moving to work on our HTML efforts. We will continue making significant contributions to open web technologies like WebKit & jQuery…”

Is Flash Dead? The Age Of The Plugin-Less Web

by Zohar Babin

Many may have found the latest news rocking, shocking, or maybe as a “little too late”…

In case you didn’t follow the news yesterday, Danny Winokur, VP of Interactive Development at Adobe made the following announcement:

“We will no longer continue to develop Flash Player in the browser to work with new mobile device configurations (chipset, browser, OS version, etc.) following the upcoming release of Flash Player 11.1 for Android and BlackBerry PlayBook.”

It wasn’t very surprising then to see the surge of excited commentary from the HTML and Web Standards community and disappointment felt by avid Flash developers.

HTML5 Video Library Update

by Zohar Babin

We’re happy to announce the deployment of version 1.5 of the Kaltura HTML5 Video Library. This  release includes a number of enhancements in the playlist handler, the addition of QUnit tests for many player features and many additional plugins. This blog post will give you a high level overview of all the changes. For more in-depth coverage follow the wiki.

The Kaltura library update has been deployed to both .org and .com to enable html5 links provided to you by the KMC and to the location. Its important that if you’re a Kaltura customer you contact your project manager or Kaltura support to update your script includes to the .com hosted version of the library. The .org location will continue to host the latest version of the library and is a good way to play around with new features, but is less recommend for production sites.

Thinking “Big” About Open Technology

by Michal Tsur and Leah Belsky

Most of the work we do at Kaltura is focused on creating new code that will revolutionize the way media is used in different industries. Russ’s post yesterday on “The Social Enterprise” was a perfect example of how our daily work building video widgets and apps all “adds up.”

Yet, to get here, we also spend some time thinking about BIG IDEAS.

We think about the future of open source technology in a world of open APIs, the start-up ecosystem and where Kaltura fits as one of a limited set of proponents of open technology.  We think about education, the future of digital literacy, and how we as technologists and entrepreneurs are influencing the world.

Recently we decided it’s time to share some of those ideas. We wanted to expand our thinking about Open Technology by brainstorming and writing within a community.

So, we (@leahbel, @michts) started a new blog called “Open Technology.”  It’s focused more on ideas about technology and building an open source start-up than on specific Kaltura projects, so we decided to make it a separate blog.  But we hope you’ll follow along.

You can see some of our early posts: “Why Digital Literacy? Some Thought Analysis…” or “The Future of Open Source Licenses in 2011.”  We’ll be sure to share some of the “best of” here as well.

We invite you to read along, join the discussion, and “think big” with us.

Open Video Conference 2011

by Perry.Fetterman

Dear Kaltura & Open Video Enthusiasts….

It’s that time of year again!!! The 2011 Open Video Conference is only two weeks away and if you haven’t registered yet, we recommend you do so as soon as possible as space is limited.

This years Open Video Conference will include many of the familiar events you have come to expect from the team at OVC; hack sessions, working groups, open video developer events, and general open video discussions. Click here for more information on the agenda and topics of discussion.

OVC is a great opportunity to meet with many of the leading open video advocates, developers, and businesses in education and media. Meet and collaborate with OVC conference attendees, HTML5 developers, the team at Kaltura and more.

At this year’s Open Video Conference, we’re adopting the philosophy of “less yak, more hack”. We’re changing the formula of past OVCs to make this year’s event more focused and outcome-oriented. Every session will be working towards building tangible outputs, from policy papers to software and hardware. This year’s event is designed especially for builders, tinkerers, makers, and doers. There will be no passive watchers here, just active participants!

Kaltura is a founding member of the Open Video Alliance, launched in 2009 as a coalition of organizations that aims to maximize free expression and innovation in online video.

Open video is the idea that the moving image should belong to everyone. This vision requires not only free and open video technologies, but also that viewers are empowered to go beyond just watching—creating, sharing, and engaging in the multimedia public sphere they now inhabit.

Looking forward to seeing you all at OVC ‘11!
