2004-09-22- added cropping capability (thanks James Stembridge)Miguel Freitas
- some vo drivers support cropping natively. (only xv and xvmc have been tested) - add software crop fallback to video_out.c - skip yuv2rgb processing at xshm for not yet cropped frames (these frames are never shown) - libmpeg2 and ffmpeg now may use crop support - bump vo api. (changes to xvmc/xxmc will follow) CVS patchset: 6991 CVS date: 2004/09/22 20:29:13

2003-12-07get rid of XINE_{ASSERT,ABORT} and useless xine_print_trace (useless). ↵Daniel Caujolle-Bert
Replace XINE_ASSERT by _x_assert, which works exaclty as assert, except that it still warns with NDEBUG defined (but don't abort). Fix missuning of assert(0), which isn't safe, abort is abort, assert is for debugging purpose only, so all assert(0) has been converted to abort() alls. In osd_preload_fonts(): alloc needed memory chunk. Define NDEBUG in CFLAGS, for non DEBUG build only. CVS patchset: 5860 CVS date: 2003/12/07 15:34:29

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

2002-08-15- reimplement independent x/y zooming.Miguel Freitas
- new helper module (vo_scale.c) with all common scaling code of video out drivers. it should greatly simplify drivers development by removing the boring frame/window calculation, aspect ratio, zooming etc. obs: not completely tested, may contain bugs and break things. also only xshm and xv have being simplified so far, others will follow shortly.
