 Revision 1.4  2005/04/29 16:51:20  mutlaqja
 Adding initial support for Video 4 Linux 2 drivers. This mean that KStars can probably control Meade Lunar Planetary Imager (LPI). V4L2 requires a fairly recent kernel (> 2.6.9) and many drivers don't fully support it yet. It will take sometime. KStars still supports V4L1 and will continue so until V4L1 is obselete. Please test KStars video drivers if you can. Any comments welcomed.

 CCMAIL: kstars-devel@kde.org

 Revision 1.3  2004/06/26 23:12:03  mutlaqja
 Hopefully this will fix compile issues on 64bit archs, and FreeBSD, among others. The assembly code is replaced with a more portable, albeit slower C implementation. I imported the videodev.h header after cleaning it for user space.

 Anyone who has problems compiling this, please report the problem to kstars-devel@kde.org

 I noticed one odd thing after updating my kdelibs, the LEDs don't change color when state is changed. Try that by starting any INDI device, and hit connect, if the LED turns to yellow and back to grey then it works fine, otherwise, we've got a problem.

 Revision 1.10  2003/10/24 16:55:18  nemosoft
 removed erronous log messages

 Revision 1.9  2002/11/03 22:46:25  nemosoft
 Adding various RGB to RGB functions.
 Adding proper copyright header too.

 Revision 1.8  2002/04/14 01:00:27  nemosoft
 Finishing touches: adding const, adding libs for 'show'

 * \defgroup colorSpace Color space conversion functions
    Colour ConVerT: going from one colour space to another.

   Format descriptions:\n
   420i = "4:2:0 interlaced"\n
           YYYY UU YYYY UU   even lines\n
           YYYY VV YYYY VV   odd lines\n
           U/V data is subsampled by 2 both in horizontal and vertical directions, and intermixed with the Y values.\n\n
   
   420p = "4:2:0 planar"\n
           YYYYYYYY      N lines\n
           UUUU          N/2 lines\n
           VVVV          N/2 lines\n
           U/V is again subsampled, but all the Ys, Us and Vs are placed together in separate buffers. The buffers may be placed in one piece of contiguous memory though, with Y buffer first,
           followed by U, followed by V.

   yuyv = "4:2:2 interlaced"\n
           YUYV YUYV YUYV ...   N lines\n
           The U/V data is subsampled by 2 in horizontal direction only.\n\n

   bgr24 = 3 bytes per pixel, in the order Blue Green Red (whoever came up with that idea...)\n
   rgb24 = 3 bytes per pixel, in the order Red Green Blue (which is sensible)\n
   rgb32 = 4 bytes per pixel, in the order Red Green Blue Alpha, with Alpha really being a filler byte (0)\n
   bgr32 = last but not least, 4 bytes per pixel, in the order Blue Green Red Alpha, Alpha again a filler byte (0)\n
