Building Theorafile for UWP
---------------------------
Theorafile uses Visual Studio 2017 to build on Xbox One.

Dependencies
------------
Before building, download libogg/libvorbis/libtheora from the Xiph website:

https://xiph.org/downloads/

After extracting the zip files, be sure to rename the directories to remove the
version numbers (for example, 'libogg-1.3.2' should be 'libogg').

Compiling
---------
1. Rename libvorbis/lib/info.c to libvorbis/lib/vinfo.c
2. Rename libtheora/lib/info.c to libtheora/lib/tinfo.c
3. Build Theorafile/visualc-winrt/libtheorafile.sln
4. Grab the output DLL, ship it!
