Use of liboggplay has been dropped in favour of implementing Ogg support directly using just libogg, libvorbis and libtheora. The WebM support is implementing using libvpx (Google's VP8 reference decoder library), libnestegg (a WebM container library), and libvorbis. They're all still builtin however so this doesn't do anything to change your NIH assertion.
