vgmstream

This is vgmstream, a library for playing streamed audio from video games.
It is very much under development. There are multiple end-user bits: a command
line decoder called "test.exe", a Winamp plugin called "in_vgmstream", a
foobar2000 component called "foo_input_vgmstream", and an xmplay plugin
called "xmp-vgmstream".

*********** IMPORTANT!! ***********
--- needed files (for Windows)  ---
Since Ogg Vorbis, MPEG audio, and other formats are now supported, you will
need to have certain DLL files.
You can get these from https://f.losno.co/vgmstream-win32-deps.zip, or in
the case of the foobar2000 component, they are all bundled for convenience.

Put libvorbis.dll, libmpg123-0.dll, libg7221_decode.dll, libg719_decode.dll,
at3plusdecoder.dll, avcodec-vgmstream-57.dll, avformat-vgmstream-57.dll, and
avutil-vgmstream-55.dll somewhere Windows can find them.
For in_vgmstream this means in the directory with winamp.exe, or in a
system directory or other directory in the PATH variable. For test.exe this
means in the same directory as test.exe, or in a system directory/PATH.

--- test.exe ---
Usage: ./test [-o outfile.wav] [-l loop count]
    [-f fade time] [-d fade delay] [-ipcmxeE] 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
    -g: decode and print oggenc command line to encode as OGG
    -b: decode and print batch variable commands
    -L: append a smpl chunk and create a looping wav
    -e: force end-to-end looping
    -E: force end-to-end looping even if file has real loop points
    -r outfile2.wav: output a second time after resetting
    -2 N: only output the Nth (first is 0) set of stereo channels

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. Please follow
the above instructions for installing the other files needed.

--- File types supported by this version of vgmstream ---

As manakoAT likes to say, the extension doesn't really mean anything, but it's
the most obvious way to identify files.

This list is not complete and many other files are supported.
