zhaoxiu.zeng	0f83415569	avcodec/vc1_mc: move median4() to mathops.h Needed for architecture specific optimizations Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Bernd Kuhls	bf6c84d7eb	Fix compile error on bfin. After the removal of all Blackfin architecture optimizations in http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=b55d3bbeed375f7b74442c4dd274d116a3e3d2e1 some includes were left behind leading to a compile error: CC libavformat/adtsenc.o In file included from ./libavcodec/get_bits.h:35, from ./libavcodec/ac3_parser.h:27, from libavformat/ac3dec.c:23: ./libavcodec/mathops.h:43:29: error: bfin/mathops.h: No such file or directory This compile error was found by buildroot autobuild system: http://autobuild.buildroot.net/results/ae0/ae056f267e907091d09d2a1546d6f1ae02fa23b9/ Signed-off-by: Bernd Kuhls <bernd.kuhls@t-online.de> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Diego Biurrun	f9279ee749	dsputil: Move ff_zigzag_direct and ff_crop_tab declarations to mathops.h	11 years ago
Vittorio Giovara	5397386eff	mathops: move macro to the only place it is used This helps in disentangling lavf and lavc too.	11 years ago
Justin Ruggles	9ae53c5860	lavc: add ff_u8_to_s8() for safe type punning of uint8_t to int8_t	11 years ago
Ben Avison	a22ae9f0c5	mpegts: Remove one 64-bit integer modulus operation per packet The common case of the pointer having increased by one packet (which results in no change to the modulus) can be detected with a 64-bit subtraction, which is far cheaper than a division on many platforms. Before After Mean StdDev Mean StdDev Change Divisions 248.3 8.8 51.5 7.4 +381.7% Overall 2773.2 25.6 2372.5 43.1 +16.9% Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Diego Biurrun	d5c62122a7	Move av_reverse table to libavcodec It is only used in that library.	12 years ago
Diego Biurrun	9734b8ba56	Move avutil tables only used in libavcodec to libavcodec.	12 years ago
Mans Rullgard	d7a4f8f8b9	Move MASK_ABS macro to libavcodec/mathops.h This macro is only used in two places, both in libavcodec, so this is a more sensible place for it. Two small tweaks to the macro are made: - removing the trailing semicolon - dropping unnecessary 'volatile' from the x86 asm Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Alex Converse	7181c4edee	cosmetics: Remove extra newlines at EOF	13 years ago
Mans Rullgard	f59bb3d8f3	mathops: remove undefined behaviour from sign_extend() This function intentionally overflows the signed range on the left shift. Using this type-punning avoids errors from the overflow checker without disabling this test globally. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	95912731c2	mathops: use MUL64 macro where it forms part of other ops Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Biurrun	8d459acc10	Add missing #includes to make headers self-contained. This fixes 'make checkheaders'.	14 years ago
Mans Rullgard	005db47011	mathops: remove ancient confusing comment Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Måns Rullgård	f2c694af28	Add UMULH() This function/macro returns the high half of the unsigned 64-bit product of two unsigned 32-bit operands. Originally committed as revision 21463 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	5e7dfb7de1	Move COPY3_IF_LT to lavc/mathops.h This obscure macro is only used in motion_est.c so having it in lavc makes more sense.

Diego Biurrun	a6493a8fbd	Rename libavcodec/i386/ --> libavcodec/x86/. It contains optimizations that are not specific to i386 and libavutil uses this naming scheme already. Originally committed as revision 16270 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Måns Rullgård	4deaa94639	Add shift argument to MULL() macro This replaces use of FRAC_BITS in the MULL() definition with a third argument specifying the shift amount. All uses of this macro are updated to pass FRAC_BITS as third argument. Originally committed as revision 15921 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	987903826b	Globally rename the header inclusion guard names. Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Måns Rullgård	ffa978f157	mathops: add MAC64, MLS64, and MLS16 MAC64: 64 += 32 x 32 (bits) MLS64: 64 -= 32 x 32 MLS16: 32 -= 16 x 16 Originally committed as revision 14198 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
