vgmstream

This is vgmstream, a library for playing streamed audio from video games.
It is very much under development. There are two end-user bits: a command
line decoder called "test", and a simple Winamp plugin called "in_vgmstream".

--- needed files (for Windows)  ---
Since Ogg Vorbis and MPEG audio are now supported, you will need to have
libvorbis.dll and libmpg123-0.dll.
I suggest getting libvorbis.dll here:
http://www.rarewares.org/files/ogg/libvorbis1.2.0.zip
and the companion Intel math dll:
http://www.rarewares.org/files/libmmd9.1.zip
And libmpg123-0.dll from this archive:
http://www.mpg123.de/download/win32/mpg123-1.4.3-x86.zip

Put libvorbis.dll, libmmd.dll, and libmpg123-0.dll somewhere Windows can find
them. For in_vgmstream this means in the directory with winamp.exe, or in a
system directory. For test.exe this means in the same directory as test.exe,
or in a system directory.

--- test.exe ---
Usage: test.exe [-o outfile.wav] [-l loop count]
    [-f fade time] [-d fade delay] [-ipPcmxeE] infile
Options:
    -o outfile.wav: name of output .wav file, default is dump.wav
    -l loop count: loop count, default 2.0
    -f fade time: fade time (seconds), default 10.0
    -d fade delay: fade delay (seconds, default 0.0
    -i: ignore looping information and play the whole stream once
    -p: output to stdout (for piping into another program)
    -P: output to stdout even if stdout is a terminal
    -c: loop forever (continuously)
    -m: print metadata only, don't decode
    -x: decode and print adxencd command line to encode as ADX
    -e: force end-to-end looping
    -E: force end-to-end looping even if file has real loop points

Typical usage would be:
test -o happy.wav happy.adx
to decode happy.adx to happy.wav.

--- in_vgmstream ---
Drop the in_vgmstream.dll in your Winamp plugins directory.
