DESCRIPTION
"AMF is a light-weight, portable multimedia framework that abstracts away most of the platform and API-specific details and allows for easy implementation of multimedia applications using a variety of technologies, such as DirectX 11, OpenGL, and OpenCL and facilitates an efficient interop between them."
