Private fork, using script to build ffmpeg for winrt

FFmpeg for WinRT

This project can be used for building ffmpeg in WinRT platform. You can use this project to build static library, or dynamic library (which linked as static library, because of the WinRT project cannot load non-WinRT dynamic library).

Build

1. You need to prepare MinGW+MSYS environment, and install mingw-developer-toolkit, mingw32-base, msys-base.
2. Download gas-preprocessor.pl , and copy it into msys bin folder.
3. Run VS2013 ARM Cross Tools Command Prompt first, and then run the msys from the command prompt. If you want to build x86 version, you should launch VS2013 x86 Native Tools Command Prompt first.
4. In the msys command prompt, open the ffmpeg folder, and run build_ffmpeg_msvc.sh. You can choice release or debug version, like sh build_ffmpeg_msvc.sh release, the default is debug. Run sh build_ffmpeg_msvc.sh quick, it means make ffmpeg without configure.
