Download it here . This new player framework implements basic video playback functionality using the HTML5 Video tag, and features JavaScript API and control UI consistent with the Silverlight version of the Player Framework.

When it comes to adaptive bit rate streaming over HTTP, file format really does matter. The Fragmented MP4 (fMP4) file format, first used by Microsoft, is the basis of IIS Smooth Streaming, Adobe HTTP Dynamic Streaming, and two industry streaming standards. fMP4 files have some distinct advantages over adaptive streaming solutions based on MPEG-2 Transport Streams, such as the proprietary HTTP Live Streaming (HLS) format developed by Apple. HLS is based on a derivative of the MPEG-2 Transport Stream (M2TS), which was developed nearly two decades ago for broadcast TV. On the other hand, the fMP4 file format was specifically designed to address the needs of modern streaming to computers, televisions, and mobile devices. fMP4 offers a number of key benefits over M2TS solutions, such as: Trick-play capabilities (e.g., fast-forward, pause, instant replay) Seamless stream adaptation to local conditions Reduced storage requirements Backwards compatibility with M2TS-based solutions Integrated digital...
This is another blog post that has been long due. I’ve written a lot about Live Smooth Streaming in my past blog posts but so far very few on On-Demand Smooth Streaming. Well, partially because getting On-Demand Smooth Streaming to work is quite simple. You just need to copy your content to the server and then everything should just work. For low volume usage, that’s pretty much all you need to care about. But if you are doing serious production systems with a large content library and significant client traffic, you would want to tune the system to its best performance in which case this blog post should be helpful to you. 1. Overview First let’s take a quick look at what’s the typical server logic when serving On-Demand Smooth Streaming requests: Figure 1. On-Demand Smooth Streaming Server Data Flow Client issues a request to get the client manifest (.ISMC file in the diagram). From the manifest file, client figures out which bitrate and timestamp it wants to request from the server....

A new release of IIS Media Services is available that adds support for REST services API's for management of publishing points as well as performance improvements for both on demand and live scenarios. Full details on how to take advantage of the performance improvements will be detailed in a later blog post. Capabilities supported via the REST services include the following: Creation & deletion of publishing points Enumeration of all web site publishing points Querying and updating publishing point settings and state Querying publishing point statistics See MSDN for full documentation on these API's. Expression Encoder 4 SP2 which was just released last week makes use of the REST API's supported in IIS Media Services 4.1 so that one can easily manage publishing points directly from within Expression Encoder. From a Live Broadcasting Project you can now: Create a new publishing point When the name for a new publishing point is specified, Expression Encoder now provides a...
Service Pack 2 (SP2) for Expression Encoder 4 was released today, and comes with some great updates. For example, SP2 adds the ability to do GPU encoding with Intel Sandy Bridge processors, and there are new multi-channel audio options including AAC and SRS support. For live scenarios, you can now control IIS Smooth Streaming publishing points from Expression Encoder. There have also been improvements in screen capture encoding, the built-in player templates, and new SDK samples to help you get started faster with building encoding applications. There are over 300 improvements and fixes in SP2. Get more detailed information on the Expression Encoder team blog. Read More...

The newly released Microsoft Media Platform Content Manager pulls together an end-to-end video workflow that allows you to create live streaming events, transcode on-demand content, manage and publish video, edit video, and insert mid-roll advertisements. This open-source release can be used by enterprises, educational institutions, and broadcasting companies to manage their video assets using a lightweight and highly-customizable solution built on Microsoft SharePoint 2010 and Microsoft Media Platform (MMP) technologies, including Silverlight 4, IIS Media Services 4.0, and Expression Encoder 4. The MMP Content Manager is one of four MMP frameworks optimized around IIS Smooth Streaming and its open-specification adaptive streaming file format, known as PIFF (the Protected Interoperable File Format , adopted by the likes of Ultraviolet and Netflix ). It greatly simplifies the workflow for complex video streaming events, such as PDC 2010 and the types shown on the IIS Media Case Studies page...
The long-awaited Beta release of IIS Transform Manager is now available! With this release, we’ve incorporated some great feature requests from a large number of customers who have been running the Alpha release in commercial production for months.
