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

blend_rgb16 changes. <- Need testing further. CVS patchset: 2773 CVS date: 2002/10/03 06:04:54
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.

- pts are 64 bit now - scr and video_out-loop run all the time - video_out cleanups - metronom cleanups - buffer type BUF_CONTROL_DISCONTINUITY is used internally now, input plugins should no longer send this one - support for individual frame durations - using nano-/usleep instead of itimer (simpler code, maybe this will help freebsd) CVS patchset: 1487 CVS date: 2002/02/09 07:13:22
