+details of audio and video formats like colorspaces, sample rates,
+multichannel configurations, etc.  It provides standardized definitions for
+those formats as well as container structures for carrying audio samples or
+video images inside an application.
+In addition, it handles the sometimes ugly task of converting between all
+these formats and provides some elementary operations (copying, scaling,
+alpha blending etc).")
