»The current situation is as follows:
Apple refuses to implement Ogg Theora in Quicktime by default (as used
by Safari), citing lack of hardware support and an uncertain patent
landscape.
Google has implemented H.264 and Ogg Theora in Chrome, but cannot
provide the H.264 codec license to third-party distributors of
Chromium, and have indicated a belief that Ogg Theora's quality-per-bit
is not yet suitable for the volume handled by YouTube.
Opera refuses to implement H.264, citing the obscene cost of the
relevant patent licenses.
Mozilla refuses to implement H.264, as they would not be able to obtain
a license that covers their downstream distributors.
Microsoft has not commented on their intent to support <video> at all.«
