PACKAGE NAME
------------
neko_libvorbis


DESCRIPTION
-----------
Ogg Vorbis is a fully open, non-proprietary, patent-and-royalty-free, general-purpose compressed audio format for mid to high quality (8kHz-48.0kHz, 16+ bit, polyphonic) audio and music at fixed and variable bitrates from 16 to 128 kbps/channel. This places Vorbis in the same competitive class as audio representations such as MPEG-4 (AAC), and similar to, but higher performance than MPEG-1/2 audio layer 3, MPEG-4 audio (TwinVQ), WMA and PAC.

See https://xiph.org/vorbis/ for more details.


SOURCE/VERSION
--------------
libvorbis-1.3.6 / 3


IRIX/MIPSPRO VERSION
--------------------
6.5.22m / 7.4.4m


ENVIRONMENT VARIABLES
---------------------
setenv CC c99 
setenv CFLAGS '-O2 -mips4 -n32' 
setenv CPPFLAGS '-I/usr/nekoware/include' 
setenv LDFLAGS '-L/usr/nekoware/lib' 

for building on mips3 systems, use:

setenv CFLAGS '-O2 -mips3 -n32'


CONFIGURE
---------
./configure --prefix=/usr/nekoware


BUILD
-----
gmake
gmake check
gmake install


KNOWN DEPENDENCIES
------------------
neko_libogg.sw.lib 3

gmake to build the package


ERRORS/MISCELLANEOUS
--------------------
The examples can be built with --enable-examples , but they will not be installed with a gmake install. Because these examples have local RPATH entries these must be installed using a libtool install script. I didn't bother with this.

If you do make the example programs yourself, you can test it by converting an example ogg file to raw PCM data and convert back to a format IRIX understands, like aiff:

$ wget https://upload.wikimedia.org/wikipedia/commons/c/c8/Example.ogg
$ vorbisfile_example < Example.ogg > Example.raw
$ dmconvert -f aiff -p audio,inraw=true,inchan=2,inrate=44100,informat=2scomp,inwidth=16,incomp=none,inbyteord=little Example.raw Example.aiff
$ playaiff Example.aiff

This package has dual support for both mips3 and mips4 architecture, controlled by the mach(CPUARCH=R4000) switch for libraries and executables.
