Microsoft's main goal for native media format support for Metro style apps was to ensure users and app developers could count on a consistently great playback experience across a wide variety of PC form factors, with modern formats used in mainstream scenarios such as:
-HTML5-based entertainment on the web
-Home movies captured using popular smartphones, point-and-shoot cameras, or AVC-HD cameras
-Streaming music, movies, and TV shows from popular services
The tables below show the video and audio formats that have built-in support for Metro style apps. Formats recommended for use by Metro style apps are a reflection of deep partnerships with hardware manufacturers for predictable hardware acceleration across PC form factors and predictable end-to-end scenario performance beyond playback such as capture, streaming, and transcoding
