The guys at FFmpeg have already written their own native decoder for the standard and managed to do so quickly and economically. Reusing parts of their h.264 codebase helped them to achieve this as both h.264 and V8 have similarities.

See Google’s VP8 video codec (http://blogs.gnome.org/rbultje/2010/06/27/googles-vp8-video-codec/) for more information.
