What audio/video formats is supported in Silverlight 2?
Windows Media Audio and Video 7, 8 ,9 (WMA, WMAPro, WMV/VC-1), as well as MP3 audio. Microsoft has announced support for H.264/MPEG AVC and AAC playback in a future version of Silverlight coming in early 2009. We will explore the need for additional formats and codec’s based on customer feedback and market need over time. Our philosophy around media formats support is “choice”. It is important to note that Silverlight is a format-agnostic RIA environment that should support any media format that users require. The addition of native H.264/AAC video and audio decode inside of Silverlight is all about providing choice to customers.
