For video Webm/VP8 [1] have open specifications, of course there is also
Theora [2] (though not as good as VP8 imo) from Xiph.org [3] the same
one that created Ogg/Vorbis [4].
For the future I would keep an eye on VP9 [5] from Google and even more
on Daala [6] again from Xiph.org/Mozilla, seem very promising.

For audio I started moving to Opus [7] also from Xiph.org/Mozilla (made
in collaboration with Skype, fully open) and now also an IETF Proposed
Standard [8].

HTH,
Simo.
