Ronald S. Bultje	c23acbaed4	Don't use ff_cropTbl[] for IDCT. Results of IDCT can by far outreach the range of ff_cropTbl[], leading to overreads and potentially crashes. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	f78cd0c243	prores-idct: fix overflow in c code. Fix the fate ref for prores-422_proxy by reverting the changes to it in commit `f492df0927` Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago

Mans Rullgard	dbb5ee8ea7	simple_idct: remove code for DCTELEM != int16 DCTELEM can never be changed to anything else, too much code depends on it. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Biurrun	e0ae2174db	simple_idct: remove disabled code	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	63613fe615	Replace WORDS_BIGENDIAN with HAVE_BIGENDIAN Originally committed as revision 19508 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Aurelien Jacobs	b250f9c66d	Change semantic of CONFIG_, HAVE_ and ARCH_*. They are now always defined to either 0 or 1. Originally committed as revision 16590 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Måns Rullgård	edf7c2b26f	simple_idct: use MUL16 and MAC16 from mathops.h Originally committed as revision 16362 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	79cb09b2f7	consistency cosmetics: Rename POWERPC identifiers to PPC. Originally committed as revision 16359 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Pettenò	be449fca79	Convert asm keyword into __asm__. Neither the asm() nor the __asm__() keyword is part of the C99 standard, but while GCC accepts the former in C89 syntax, it is not accepted in C99 unless GNU extensions are turned on (with -fasm). The latter form is accepted in any syntax as an extension (without requiring further command-line options). Sun Studio C99 compiler also does not accept asm() while accepting __asm__(), albeit reporting warnings that it's not valid C99 syntax. Originally committed as revision 15627 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Falk Hüffner	8b313a4787	Move Alpha optimized IDCT to own file. Based on a patch by Måns Rullgård <mru@users.sourceforge.net>. I've left out the idctCol2 part, because W4 has recently been decreed to be 16383, and also I doubt it will give a noticeable speedup. Originally committed as revision 1029 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago

Falk Hüffner	3155c994b6	Reintroduce lost idctSparseCol for Alpha.
