+@item The target @file{make wininstaller} can be used to create a
+Nullsoft based Windows installer for FFmpeg and FFplay. @file{SDL.dll}

+@item Visual C++ compatibility: if you used @code{./configure --enable-shared} 
+when configuring FFmpeg, then FFmpeg tries to use the Microsoft Visual
+C++ @code{lib} tool to build @code{avcodec.lib} and
+@code{avformat.lib}. With these libraries, you can link your Visual C++
+code directly with the FFmpeg DLLs.
