Michael Niedermayer	30981a966f	lavc: split snow and dirac DWTs There is only about 4 lines of common code, so it alot cleaner when seperated. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Diego Biurrun	a0c5917f86	Drop Snow codec Snow is a toy codec with no real-world use and horrible code.	12 years ago
Diego Biurrun	bcc45d6348	x86: avcodec: Drop silly "_mmx" suffixes from filenames	12 years ago
Mans Rullgard	c318626ce2	x86: rename libavutil/x86_cpu.h to libavutil/x86/asm.h This puts x86-specific things in the x86/ subdirectory where they belong. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Diego Biurrun	239fdf1b4a	x86: build: replace mmx2 by mmxext Refactoring mmx2/mmxext YASM code with cpuflags will force renames. So switching to a consistent naming scheme beforehand is sensible. The name "mmxext" is more official and widespread and also the name of the CPU flag, as reported e.g. by the Linux kernel.	12 years ago
Ronald S. Bultje	8123e0901f	x86: place some inline asm under #if HAVE_INLINE_ASM Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Ronald S. Bultje	d9669eab0b	dwt: remove variable-length arrays Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Ronald S. Bultje	bec207f9f9	snowdsp: explicitily state instruction size. Fixes a compile error with clang at -O0.	13 years ago
Reimar Döffinger	5c13b5bb39	Add operand size to add instructions. In these cases it can't be guessed from the operands (at least not necessarily), and it seems some clang versions refuse to compiler it. Fixes ticket #303. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
İsmail Dönmez	9276bdddca	snowdsp: Explicitly state the operand sizes Fixes compilation with clang's builtin assembler Patch by İsmail Dönmez, ismail at namtrac dot org Originally committed as revision 25331 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	c6c98d0897	Move mm_support() from libavcodec to libavutil, make it a public function and rename it to av_get_cpu_flags(). Originally committed as revision 25076 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	7160bb716b	Rename FF_MM_ symbols related to CPU features flags as AV_CPU_FLAG_ symbols, and move them from libavcodec/avcodec.h to libavutil/cpu.h. Originally committed as revision 25040 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Måns Rullgård	c0ec9918b0	Remove global mm_flags variable Originally committed as revision 24909 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Måns Rullgård	05aec7bb87	Separate DWT from snow and dsputil This moves the DWT functions from snow.c and dsputil.c to a file of their own. A new struct, DWTContext, holds the function pointers previously part of DSPContext. Originally committed as revision 22522 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	c26e58e32c	Add some missing #includes Originally committed as revision 22258 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	84dc2d8afa	Remove DECLARE_ALIGNED_{8,16} macros These macros are redundant. All uses are replaced with the generic DECLARE_ALIGNED macro instead. Originally committed as revision 22233 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	c67278098d	Move array specifiers outside DECLARE_ALIGNED() invocations Originally committed as revision 21377 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Matthieu Castet	ecf05a5971	Remove useless casting in asm "m" operand. Patch by Matthieu Castet, castet D matthieu A free D fr Originally committed as revision 18054 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
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
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
Diego Biurrun	245976da2a	Use full path for #includes from another directory. Originally committed as revision 13098 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Ramiro Polla	40d0e665d0	Do not misuse long as the size of a register in x86. typedef x86_reg as the appropriate size and use it instead. Originally committed as revision 13081 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Reimar Döffinger	eafa1c90e5	Replace complicated and currently broken manual alignment code by DECLARE_ALIGNED_16. Fixes crash in ff_snow_horizontal_compose97i_sse2 Originally committed as revision 10261 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Michael Niedermayer	629750290f	avoid overflow in the 3rd lifting step, this now needs mmx2 at minimum (patch for plain mmx support is welcome ...) Originally committed as revision 10226 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Michael Niedermayer	9caa1cccb9	prevent one overflow in the first vertical lifting step Originally committed as revision 10224 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	3e0f7126b5	update mmx code to latest snow changes note, the code likely can overflow and thus needs some more changes sse2 updated too but disabled as it is untested Originally committed as revision 10223 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Michael Niedermayer	ce611a27be	Change rounding of the horizontal DWT to match the vertical one. This allows some simplifications and optimizations and should not have any effect on quality. Originally committed as revision 10172 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
