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. 00026 00027 CCMAIL: kstars-devel@kde.org 00028 00029 Revision 1.3 2004/06/26 23:12:03 mutlaqja 00030 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. 00031 00032 Anyone who has problems compiling this, please report the problem to kstars-devel@kde.org 00033 00034 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. 00035 00036 CCMAIL: kstars-devel@kde.org 00037 00038 Revision 1.10 2003/10/24 16:55:18 nemosoft 00039 removed erronous log messages 00040 00041 Revision 1.9 2002/11/03 22:46:25 nemosoft 00042 Adding various RGB to RGB functions. 00043 Adding proper copyright header too. 00044 00045 Revision 1.8 2002/04/14 01:00:27 nemosoft 00046 Finishing touches: adding const, adding libs for 'show' 00047 */ 00048 00049 00050 #ifndef CCVT_H 00051 #define CCVT_H 00052 00053 #ifdef __cplusplus 00054 extern "C" { 00055 #endif 00056 00057 /* Colour ConVerT: going from one colour space to another. 00058 ** NOTE: the set of available functions is far from complete! ** 00059 00060 Format descriptions: 00061 420i = "4:2:0 interlaced" 00062 YYYY UU YYYY UU even lines 00063 YYYY VV YYYY VV odd lines 00064 U/V data is subsampled by 2 both in horizontal 00065 and vertical directions, and intermixed with the Y values. 00066 00067 420p = "4:2:0 planar" 00068 YYYYYYYY N lines 00069 UUUU N/2 lines 00070 VVVV N/2 lines 00071 U/V is again subsampled, but all the Ys, Us and Vs are placed 00072 together in separate buffers.
