     "Libdvdnav is a library for developers of multimedia
applications.  It allows easy use of sophisticated DVD navigation features
such as DVD menus, multiangle playback and even interactive DVD games.  All
this functionality is provided through a simple API which provides the DVD
playback as a single logical stream of blocks, intermitted by special
dvdnav events to report certain conditions.  The main usage of libdvdnav is
a loop regularly calling a function to get the next block, surrounded by
additional calls to tell the library of user interaction.  The whole
DVD virtual machine and internal playback states are completely
encapsulated.")

library, upon which multimedia APIs can be built.  Gavl handles all the
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).")

provide a way to share these simple effects between many
applications, avoiding their reimplementation by different projects.
