Winamp 2.x and 5.x input plugin for Opus file
== PURPOSE ==
Opus is a quite new audio file format, very good for generic lossy compression especially at low bitrates including voice.
I developed this plugin because I wanted to be able to play OPUS files with Winamp 2, both on my Windows XP machine and an old Windows 98 SE, That is still used for playing music and for retro gaming at my home.
I had to build myself the libraries because they include dependencies that are not present on this old OS.
The plugin was tested and works fine on Windows 95/98SE/NT4/2000/XP/2003/7/8/10/11.
There is a very good plugin that was already written by thinktink but it only works for Winamp 5 and recent windows versions.
I provide this plugin for compatibility with old platforms. to my knowledge, this is the only Opus player for Windows 9x. and some of you may still use Winamp 2 for some reasons.
== THIS PROGRAM IS BASED ON ==
libopus 1.3.1, * opusfile 0.12 (http://opus-codec.org/) libogg 1.3.2 (http://xiph.org/ogg/) Compiled using gcc from TDM-GCC-5.1, (MinGW) running on Windows Server 2003

UNICODE filename support (v0.666+) under Windows NT4+ as well as UNICODE tags support (v0.555+).
== LIMITATIONS ==
I did not want to lose time so there are some limitations, they may change in the future if I continue the project.
No way to edit tags.
UTF-8 is not really supported under Win9x; all tags are converted to local codepage for display Under NT the UTF-8 strings are converted to UTF-16 since 0.555.
In the Winamp playlist only the filename/URL will be visible. Since v0.911 proper format will be shown in the PL on Winamp 5.x
