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
Loren Merritt	e17ccf60fe	huffyuv: add some const qualifiers Originally committed as revision 20290 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Loren Merritt	2f77923d72	simd add_hfyu_left_prediction 2.2x faster than C on conroe, 3.6x on penryn. 4-6% faster huffyuv decoding if using left or plane mode and yuv Originally committed as revision 20287 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Justin Ruggles	fde82ca7e4	Move autocorrelation function from flacenc.c to lpc.c. Also rename the corresponding dsputil functions and remove their dependency on the FLAC encoder. Fixes Issue1486. Originally committed as revision 20266 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alexander Strange	2d4bbdecee	Huffyuv: Add missing const to src pointers in dsputil functions. Originally committed as revision 20259 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	75df2edbb9	Add support for hardcoded ff_sin_* tables. Originally committed as revision 20244 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	aafd659518	Do not initialize ff_cos_* tables again in rdft_init, they are already initialized by ff_fft_init and using different code can result in slightly different values, in addition it crashes when the tables are hardcoded. On amd64 this slightly changes qdm2 output. Originally committed as revision 20237 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
Nathan Caldwell	73c6f59830	Move HuffYUV left prediction to dsputil. Patch by Nathan Caldwell, saintdev gmail Originally committed as revision 20179 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	952e872198	Drop unused args from vector_fmul_add_add, simpify code, and rename The src3 and step arguments to vector_fmul_add_add() are always zero and one, respectively. This removes these arguments from the function, simplifies the code accordingly, and renames the function to better match the new operation. Originally committed as revision 20061 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	53b572118e	Add some dsputil functions useful for AAC decoder Originally committed as revision 19955 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Måns Rullgård	01b2214758	Merge FFTContext and MDCTContext Originally committed as revision 19931 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	68336ea8d4	10l: fix ff_fft_init_arm() prototype Originally committed as revision 19865 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	f486321395	Move per-arch fft init bits into the corresponding subdirs Originally committed as revision 19864 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Vitor Sessak	6776061b04	Add two more sizes to ff_sine_windows[] and also pad it with NULLs so that FF_ELEMS(ff_sine_windows[x]) == 1 << x. Fix issue 1384. Originally committed as revision 19862 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	edc0f5dcba	ARM: NEON optimised MDCT Originally committed as revision 19819 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	15 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	15 years ago
Reimar Döffinger	c55e5b5fee	ff_sine_windows table contains only constant data, too. Originally committed as revision 19785 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 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	15 years ago
Måns Rullgård	e78516c6d8	One declaration of mm_flags is enough Originally committed as revision 19740 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	4e36a5b46f	Move declarations of some mmx functions to dsputil_mmx.h Originally committed as revision 19739 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	5b1b014761	Move DECLARE_ALIGNED_8 definition next to DECLARE_ALIGNED_16 Originally committed as revision 19738 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	c4d6d318cf	Make DECLARE_ALIGNED_8 align to 8 bytes, never to 16 The DECLARE_ALIGNED_8 macro is defined to align to 16 bytes instead the 8 suggested by the name on some CPUs. None of the uses of this macro ever need 16-byte alignment, cases which once did having been changed to always specify 16 bytes explicitly. Originally committed as revision 19737 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Vitor Sessak	50e23ae9d3	Mark parameter src of vector_clipf() as const Originally committed as revision 19729 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Vitor Sessak	0a68cd876e	SSE optimized vector_clipf(). 10% faster TwinVQ decoding. Originally committed as revision 19728 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	4f717c69ed	idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall. Includes mmx2 asm for the various functions. Note that the actual idct still does not have an x86 SIMD implemtation. For wmv3 files using regular idct, the decoder just falls back to simple_idct, since simple_idct_dc doesn't exist (yet). Originally committed as revision 19204 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Siarhei Siamashka	7d485f165f	Support for getting (i)MDCT output multiplied by a constant scaling factor. Scaling (i)MDCT output has no runtime overhead and can be used to improve performance of audio codecs. All the changes are only needed in 'ff_mdct_init' function and slow down initialization a bit. Originally committed as revision 18855 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
