2003-03-08first step towards fixing the DVD menu highlighting problemsMichael Roitzsch
The problem arises because of inconsistent usage of libdvdread's functions regarding NAV packet reading: libspudec and the dxr3 spu decoder use some of these functions, but they used to have private copies of the relevant files of libdvdread. These do not work any more now, since the internal layout of NAV packets in libdvdread changed lately. So we should always use the functions from current libdvdread. Please note that highlights might not work yet. The next step will be to sync libdvdnav. Stay tuned. CVS patchset: 4371 CVS date: 2003/03/08 14:11:52
2003-02-28Xine assert() replacement:Stephen Torri
All assert() function calls, with exceptions of libdvdread and libdvdnav, have been replaced with XINE_ASSERT. Functionally XINE_ASSERT behaves just likes its predecesor but its adding the ability to print out a stack trace at the point where the assertion fails. So here are a few examples. assert (0); This use of assert was found in a couple locations most favorably being the default case of a switch statement. This was the only thing there. So if the switch statement was unable to find a match it would have defaulted to this and the user and the developers would be stuck wonder who died and where. So it has been replaced with XINE_ASSERT(0, "We have reach this point and don't have a default case"); It may seem a bit none descriptive but there is more going on behind the scene. In addition to checking a condition is true/false, in this case '0', the XINE_ASSERT prints out: <filename>:<function name>:<line number> - assertion '<assertion expression>' failed. <description> An example of this might be: input_dvd.c:open_plugin:1178 - assertion '0' failed. xine_malloc failed!!! You have run out of memory XINE_ASSERT and its helper function, print_trace, are found in src/xine-utils/xineutils.h CVS patchset: 4301 CVS date: 2003/02/28 02:51:47

2002-09-30Fixes and performance improvements to the alphablend.c code.James Courtier-Dutton
The fixes involved getting blend_rgb16 to correctly handle different colours in the highlight area and general overlay area. Another fix involved fixing the overlay scaling function so that it scales in the same proportion as the yuv2rgb code. Currently, blend_yuv has not been updated. blend_rgb16 has been improved. blend_rgb24 and blend_rgb32 have not been changed and will probably not work now. The performance improvements are due to two things: - 1) Special detection of overlays without any buttons/clip areas. This is detected by ensuring overl->clip_top = -1 when no button is present. 2) Reorganise the blending code so that for each time round the loop, the fewest possible IF statements are executed. So, for overlays without any buttons, not checks for the clip area is done. For overlay with buttons, state is kept as to whether we are above, to the left, inside or to the right or below the clip area, thus saving having to do IF statements each time round the loop to find out where we are.

2002-07-06Button areas in the nav packets are in screen coordinated.Michael Roitzsch
Overlay clipping areas are in overlay coordinates. Therefore, up to now, the menu highlight positions were only correct, when the menu subpicture started at (0,0) on screen. Although this seems to be common, it is not necessarily true and I have dvds here, for which it is not. The fix is easy: Correctly convert the button areas to clipping areas by subtracting the subpictures display offset. CVS patchset: 2221 CVS date: 2002/07/06 16:36:43
