The HTML standard does not currently require support for any particular video
or audio codecs, because it's clear that currently there's no format all
browsers will support.  This matches how it specifies <img> or <object> -- no
particular formats are mentioned.  When browsers finally all agree on a
standard format, like maybe WebM, the spec might require that, but not before
then.  This was discussed at extreme length a couple of years ago.

(Incidentally: FLV is a container format, Xvid is an encoder, and MPEG3 and
MPEG4 are groups of standards.  None are codecs.  H.264, FLAC, and Speex are
the only codecs on your list.  FLAC is lossless, so would be a very poor choice
for web-based audio players.  H.264 is supported by IE9 and Safari, but not
other browsers, because it's patented-encumbered.  Speex is not supported for
HTML5 audio by any browser that I know of.)
