If Firefox/Mozilla folks want to establish HTML5 as a viable standard for
delivery of video they are just going to have to bite the bullet here and
give into the fact that their market share does not give them ability to
push a political agenda by denying users easy functionality.
Sorry. That is just not how it works.
I support the use of Theora over H.264 very much. But it is not something I
nor Mozilla org has any control over. The good thing is that Theora and
H.264 are not mutually exclusive. Just like PNG and Jpeg are not mutually
The issue with H.264 and what to do about supporting 'patent encumbered'
media has been done to death on Linux. There are effective and widely used
solutions in place for dealing with these issues... it's just a matter of
Mozilla taking advantage of them. (My favorite is of course Gstreamer +
ffmpeg gstreamer plugin)
As far as other platforms XP does not support H.264 out of the box, but
Vista and Windows 7 does. As does OS X. For XP not supporting it that makes
life difficult for Mozilla, but it is a very good reason for people to
support the use of Theora.
