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.

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

Ronald S. Bultje	157cb0694a	Rename PACK4x8() to PACK4UINT8(). Originally committed as revision 23721 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	b39a2d19d4	Add a macro to pack 4 bytes into native byte-order so they can be written at once using a single 32-bit store. Originally committed as revision 23715 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	e969e261a5	Use standard C for implementing sign_extend() and zero_extend(). This fixes compilation of probetest Originally committed as revision 23116 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	48960b8f24	Add zero_extend() function Originally committed as revision 21947 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	5e46be96f8	Move NEG_[US]SR32 macros to mathops.h Originally committed as revision 21873 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 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. See discussion here: http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2008-November/056561.html Originally committed as revision 21346 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 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

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

Diego Biurrun	b78e7197a8	Change license headers to say 'FFmpeg' instead of 'this program/this library' and fix GPL/LGPL version mismatches. Originally committed as revision 6577 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
