title: ffmpeg ERROR: libnpp not found in windows
body: <p>I`m trying to compile ffmpeg in windows with nvidia libraries for hardware acceleration using MinGW/msys. tried to follow the instruction on <a href="https://developer.nvidia.com/ffmpeg" rel="noreferrer">nvidias website</a> (section: Getting Started with FFmpeg/libav using NVIDIA GPUs). configured with <strong>--enable-nonfree --disable-shared --enable-nvenc --enable-cuda --enable-cuvid --enable-libnpp --extra-cflags=-Ilocal/include --extra-cflags=-I../common/inc --extra-ldflags=-L../common/lib/x64 --prefix=ffmpeg</strong> but stopped at <strong>"ERROR: libnpp not found."</strong> where common folder is downloaded from <a href="https://developer.nvidia.com/nvidia-video-codec-sdk#Download" rel="noreferrer">NVIDIA Video Codec SDK </a> but there is no npp libs or header files. is there any solution for that? thanks for edvice.</p>
