/*
* vidixlib.h
* VIDIXLib - Library for VIDeo Interface for *niX
* This interface is introduced as universal one to MPEG decoder,
* BES == Back End Scaler and YUV2RGB hw accelerators.
* In the future it may be expanded up to capturing and audio things.
* Main goal of this this interface imlpementation is providing DGA
* everywhere where it's possible (unlike X11 and other).
* Copyright 2002 Nick Kurshev
* Licence: GPL
* This interface is based on v4l2, fbvid.h, mga_vid.h projects
* and personally my ideas.
* NOTE: This interface is introduces as APP interface.
* Don't use it for driver.
* It provides multistreaming. This mean that APP can handle
* several streams simultaneously. (Example: Video capturing and video
* playback or capturing, video playback, audio encoding and so on).
