Diego Biurrun	e10252483e	Only enable SSE/3DNOW optimizations when they have been enabled at compilation. Fixes shared build with SSE/3DNOW disabled but MMX and yasm enabled. Originally committed as revision 17451 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	b3183ad034	prettyprinting whitespace cosmetics Originally committed as revision 17443 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
Alex Converse	6860254044	Add the rdft family of transforms (fft/ifft of an all real sequence) to dsputil. Originally committed as revision 16864 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
Dominik Mierzejewski	82d1605fe7	Remove duplicated MM_* macros for CPU capabilities from dsputil.h. Add missing one for FF_MM_ALTIVEC to avcodec.h. Rename all the occurences of MM_* to the corresponding FF_MM_*. Originally committed as revision 15770 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Loren Merritt	d46ac5bfde	mdct wrapper function to match fft Originally committed as revision 14703 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Loren Merritt	46803f4f67	optimize imdct_half: remove tmp buffer. skip fft reinterleave pass, leaving data in a format more convenient for simd. merge post-rotate with post-reorder. Originally committed as revision 14700 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Loren Merritt	49c0dd754c	indent Originally committed as revision 14699 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Loren Merritt	5d0ddd1a9f	split-radix FFT c is 1.9x faster than previous c (on various x86 cpus), sse is 1.6x faster than previous sse. Originally committed as revision 14698 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Loren Merritt	b9fa32082c	exploit mdct symmetry 2% faster vorbis on conroe, k8. 7% on celeron. Originally committed as revision 14207 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
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
Loren Merritt	60ae06e77e	r5954 broke fft on cpus with 3dnow but without mm3dnow.h Originally committed as revision 5974 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Loren Merritt	bcfa3e58ee	3dnow2 implementation of imdct. 6% faster vorbis and wma. Originally committed as revision 5954 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
