Silverlight 3 to Support Streaming HD Flash Video Encoding

An upcoming version of Silverlight, named Silverlight 3, will be able to play high-definition videos used in Flash and music in iTunes' AAC format. The version add to the variety of streamed HD video and high-fidelity music that broadcasters are expected to bring online.

Silverlight 3 won't be able to play .flv or .swf content. An early preview of Silverlight 3 will be shown at the International Broadcasting Conference (IBC) 2008 in Amsterdam this week.

Scott Guthrie, Vice President, Microsoft .NET Developer Division, said, "At IBC 2008 we will be demonstrating a technology preview of H.264 video and Advanced Audio Coding (AAC) audio playback support in Silverlight, and H.264 authoring using Microsoft Expression Encoder and Windows Server 2008 for delivery. Until now, Silverlight has supported the SMPTE VC-1 and Windows Media formats, as well as MP3 for audio, enabling customers to take advantage of broad support across the Windows Media ecosystem, including third-party tools, service providers and content delivery networks."

According to published press reports, Silverlight 3 is expected to ship early next calendar year. A beta of Silverlight 3 is expected soon after Silverlight 2 ships this fall.

Microsoft Silverlight is a cross-browser, cross-platform, and cross-device plug-in for delivering the next generation of .NET based media experiences and rich interactive applications for the Web.

By using Expression Studio and Visual Studio, designers and developers can collaborate more effectively using the skills they have today to light up the Web of tomorrow.

    Just so you know, Flash video is actually an FLV file. Flash and other video delivery technologies can play H.264 video, but saying that Silverlight will be able to play Flash video is completely false.

    Thanks for your comments Lee. I’ve updated the entry to refer to the format. Silverlight 3 announcements won’t support playing .flv files as Lee mentions.

  3. Kyle says:

    To clarify a bit on whats been said, this does mean Silverlight will be able to play Flash’s highest quality video format.  That video format (introduced in Flash MovieStar) is MP4 H.264/AAC.  So that means you could stream say, hi-quality youtube videos.
