Diego Biurrun	adbfc605f6	doxygen: Consistently use '@' instead of '\' for Doxygen markup. Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Vitor Sessak	9d35fa520e	Add AVX FFT implementation. Signed-off-by: Reinhard Tartler <siretart@tauware.de>	14 years ago
Mans Rullgard	dba9852935	ARM: NEON fixed-point FFT Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	bc154882e1	Fixed-point MDCT with 32-bit unscaled output Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	7087ce08c8	Fixed-point FFT and MDCT	14 years ago
Mans Rullgard	e87a6f0dc9	Move ff_dct_init_mmx declaration to dct.h This was missed in `0aded94`. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	0aded9484d	Move dct and rdft definitions to separate files This leaves fft.h with only the core FFT and MDCT definitions thus making it more managable. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	4538729afe	Move sine windows to a separate file These windows do not really belong in fft/mdct files and were easily confused with the similarly named tables used by rdft. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	a45fbda994	Move ff_kbd_window_init() to a separate file This function is not tightly coupled to mdct, and it's in the way of making a fixed-point mdct implementation. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	26f548bb59	fft: remove inline wrappers for function pointers This removes the rather pointless wrappers (one not even inline) for calling the fft_calc and related function pointers. 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
Loren Merritt	11ab1e409f	FFT: factor a shuffle out of the inner loop and merge it into fft_permute. 6% faster SSE FFT on Conroe, 2.5% on Penryn. Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net> (cherry picked from commit `e6b1ed693a`)	14 years ago

Diego Elio Pettenò	d4a847711d	Mark C base versions of FFT functions static to fft.c Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit `7767d8d361`)	14 years ago

Alex Converse	c36b2c010e	Revert unintended changes to fft.h from r24890. Originally committed as revision 24891 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Nathan Caldwell	af00dddeca	aacenc: Rename Psy3gpp* structs to AacPsy* This allows cleaner implementation of other psymodels using the existing structs. It also will make it easier to interchange individual parts of the psymodel to create hybrid models. Patch by: Nathan Caldwell <saintdev@gmail.com> Originally committed as revision 24890 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Vitor Sessak	4dcc4f8eaa	SSE optimized 32-point DCT Originally committed as revision 24077 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
Vitor Sessak	06d01188e9	More mp{1,2,3} 32-point DCT transform to our common DCT framework. Should allow for future SIMD optimizations. Originally committed as revision 23912 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	49bd8e4b84	Fix grammar errors in documentation Originally committed as revision 23904 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	dd93649b71	Remove VLA in ff_kbd_window_init, limit window size to 1024 Originally committed as revision 23755 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Vitor Sessak	e1484ebed6	Implement the discrete sine/cosine transforms DCT-I and DST-I Originally committed as revision 22649 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	a8bb9ea532	ARM: NEON optimised RDFT Originally committed as revision 22641 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Vitor Sessak	e30ab38e94	Call DCT by function pointer. Needed for any future ASM implementation and allows further cleanup. Originally committed as revision 22617 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Vitor Sessak	2758004fce	DCT: remove unused field from context Originally committed as revision 22615 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	2881c83127	Call rdft by function pointer Call the RDFT by a function pointer like other FFT related transforms. This makes instruction set optimized versions possible. Based on patch by Alex Converse. Originally committed as revision 22609 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	c70948315b	Create a public API for FFT family of functions Originally committed as revision 22291 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	41ea18fb0d	Give RDFT types more meaningful names Originally committed as revision 22290 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
