+ "Gavl is short for Gmerlin Audio Video Library. It is a low level
+library, upon which multimedia APIs can be built. Gavl handles all the
+details of audio and video formats like colorspaces, samplerates,
+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 to convert between all
+these formats and provides some elementary operations (copying, scaling,
+alpha blending etc).")
