|
* 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).
