multimedia/gavl 1.4.0_4 DragonFly

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)
