VVmpeg is a simple wrapper library to utilize frequently used FFmpeg as a DLL type in Windows. VVmpeg can be easily employed to programs since it provides the functions of FFmpeg as a DLL file type where previous FFmpeg is provided with console programs made with exe files. Therefore, it is also possible to make libraries from a tool such as FFmpeg into a form of a program containing GUI.
