Diego Elio Pettenò	7767d8d361	Mark C base versions of FFT functions static to fft.c Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Måns Rullgård	fe20bdf9db	Indent Originally committed as revision 23958 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	588d28ac08	Remove vestiges of radix-2 FFT Patch (mostly) by Loren Merritt Originally committed as revision 23957 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 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	2ed6f39944	Replace many includes of libavutil/common.h with what is actually needed This reduces the number of false dependencies on header files and speeds up compilation. Originally committed as revision 22407 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	1429224b04	Move FFT parts from dsputil.h to fft.h Originally committed as revision 22235 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	b5ab9b59e0	Fix build with --disable-mdct Originally committed as revision 21764 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	1ffc6e8327	Add ff_init_ff_cos_tabs function and use it in rdft.c to ensure that the necessary ff_cos_tabs tables are initialized. Fixes issue 1507 (QDM2 broken since r20237 without hardcoded tables). Originally committed as revision 20464 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	223217746c	Pad ff_cos_tabs and ff_sin_tabs so that index n points to the table for n bits. While this "wastes" up to 2x32 bytes it makes the code slightly simpler and less confusing. Originally committed as revision 20449 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	4ee726b670	Move/add COSTABLE/SINTABLE macros to dsputil to add extern definitions for ff_cos_* and ff_sin_* without introducing too much code duplication. Originally committed as revision 20243 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	16aec74761	Use hardcoded instead of runtime-calculated ff_cos_* tables if --enable-hardcoded-tables was used. Due to the size, the code for the tables is generated at compile time. Originally committed as revision 20232 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	5bd1fc6fbd	fft_dispatch array should be const Originally committed as revision 20223 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Måns Rullgård	46c32e2654	Prepare for optimised forward MDCT implementations This adds a function pointer for forward MDCT to FFTContext and initialises it with the existing C function. ff_calc_mdct() is changed to an inline function calling the selected version as done for other fft/mdct functions. Originally committed as revision 19818 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Måns Rullgård	648d792042	ARM: NEON optimised FFT and MDCT Vorbis and AC3 ~3x faster. Parts by Naotoshi Nojiri, naonoj gmail Originally committed as revision 19806 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Reimar Döffinger	faca56191c	The ff_cos_tabs table itself is constant, too, so mark it as such. Originally committed as revision 19784 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 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
Loren Merritt	ebbafcb454	sse implementation of imdct. patch mostly by Zuxy Meng (zuxy dot meng at gmail dot com) Originally committed as revision 6311 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Loren Merritt	652c59b967	use ff_fft_calc_3dn2 instead of sse on a K8. 1.5% faster vorbis. Originally committed as revision 6024 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Loren Merritt	1e4ecf26f5	ff_fft_calc_3dn/3dn2/sse: convert intrinsics to inline asm. 2.5% faster fft, 0.5% faster vorbis. Originally committed as revision 6023 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

Benjamin Larsson	7943355485	ff_fft_init now double checks that the system has mm3dnow.h before checking if the cpu can do 3dnow at all. This bug caused amd cpu's without sse to not have a working fft function. Ie no wma, cook or vorbis decoder. Originally committed as revision 5570 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
