Re: [9fans] Where is mp3dec, pac4dec vorbisdec?

[Christopher Nielsen <cnielsen@pobox.com>]

there are several codec and frontend ports in /n/sources/cnielsen.

the following libraries:
libogg
libvorbis
libFLAC
libOggFLAC
libfaac

and the following frontends/utilities:
faac
oggenc
vorbiscomment
metaflac
flac
bladeenc
cuetools

oggdec and faad should be no-brianer ports. i'll see if i can
do them tonight and toss them up there, too.
