This is the W996[87]CF driver source code in pure text, for submission to the Linux kernel 2.4 and 2.6.
The code to be submitted has been sent to the USB manteiner as well. There are six files below (separated by "-" lines), in order: 1) w9968cf.h 2) w9968cf.externaldef.h 3) w9968cf_decoder.h 4) w9968cf.c (for Linux 2.6) 5) w9968cf.c (for Linux 2.4) 6) w9968cf.txt The optional module, which provides some video post-processing functions like video decoding, colour conversion and upscaling, has not been attached to this text, since they are usually done in user-space context. The complete source code can be found at: http://go.lamarinapunto.com . ---------------------------------- w9968cf.h ---------------------------------- /*************************************************************************** * Video4Linux driver for W996[87]CF JPEG USB Dual Mode Camera Chip. * * * * Copyright (C) 2002 2003 by Luca Risolia <[EMAIL PROTECTED]> * * * * This program is free software; you can redistribute it and/or modify * * it under the terms of the GNU General Public License as published by * * the Free Software Foundation; either version 2 of the License, or * * (at your option) any later version. * * * * This program is distributed in the hope that it will be useful, * * but WITHOUT ANY WARRANTY; without even the implied warranty of * * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
