+Libav can use the AMD Advanced Media Framework library for accelerated H.264 and HEVC encoding on VCE enabled hardware under Windows.
+
+To enable support you must obtain the AMF framework header files from @url{https://github.com/GPUOpen-LibrariesAndSDKs/AMF.git}.

+Create an @code{AMF/} directory in the system include path.
+Copy the contents of @code{AMF/amf/public/include/} into that directory.

You can use the @code{-formats} and @code{-codecs} options to have an exhaustive list.
