It allows VLD H264 decoding using DXVA2 (GPU assisted decoding API under VISTA and Windows 7). It is implemented by using AVHWAccel API. It has been tested successfully for some time in VLC using an nvidia card on Windows 7. To compile it, you need to have the system header dxva2api.h (either from microsoft or using http://downloads.videolan.org/pub/videolan/testing/contrib/dxva2api.h) The generated libavcodec.dll does not depend directly on any new lib as the necessary objects are given by the application using FFmpeg.
