- * vidixlib.c
- * 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).
