browser - HTML5 audio codecs, support for other formats besides OGG -

-

i started tinkering around html5 , interested in audio tag. though 1 thing came attention, appears ogg format supported in firefox!

i understand because mp3 , other codecs proprietary software , require license use. how html5 audio (and video) going catch on if can use ogg?? or not world hooked mp3 or apple's aac.

and further hinder things seems mozilla natively supporting ogg.

so i'm curious. why can't firefox, , other browsers, use system installed codecs playing media? why have installed browser, or depend on technologies flash? seems bad design me.

perhaps, i'm naive this, whole codec war nuisance. can point me information, laws, , other information regarding why browsers can't use system installed codecs? hear other users opinions well. thanks!

edit in case comes off not being programming question, want clarify me issue directly affects web programmers. example, in case of audio support, have use flash? or these issues handled in html5. seem things going, technology-wise, in regards issue?

the <object> or <embed> tag used reference media, , allowed transcend browser handling. purpose of html5's media standardize common encoding (lowest common denominator if will) across platforms , have browser-native player. ogg container , various encodings make perfect sense.
