|
* VIDIX - 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 driver interface.
|
|
* Don't use it for APP.
