| | | | Originally committed as revision 20290 to svn://svn.ffmpeg.org/ffmpeg/trunk
* simd add_hfyu_left_predictionLoren Merritt2009-10-18
| | | | | | | 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
* Move autocorrelation function from flacenc.c to lpc.c. Also rename theJustin Ruggles2009-10-17
| | | | | | | | 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
* Huffyuv: Add missing const to src pointers in dsputil functions.Alexander Strange2009-10-16
| | | | Originally committed as revision 20259 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Add support for hardcoded ff_sin_* tables.Reimar Döffinger2009-10-15
| | | | Originally committed as revision 20244 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move/add COSTABLE/SINTABLE macros to dsputil to add extern definitionsReimar Döffinger2009-10-15
| | | | | | for ff_cos_* and ff_sin_* without introducing too much code duplication. Originally committed as revision 20243 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Do not initialize ff_cos_* tables again in rdft_init, they are alreadyReimar Döffinger2009-10-15
| | | | | | | | 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
* Use hardcoded instead of runtime-calculated ff_cos_* tables ifReimar Döffinger2009-10-14
| | | | | | | --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
* Move HuffYUV left prediction to dsputil.Nathan Caldwell2009-10-06
| | | | | | Patch by Nathan Caldwell, saintdev gmail Originally committed as revision 20179 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Drop unused args from vector_fmul_add_add, simpify code, and renameMåns Rullgård2009-09-27
| | | | | | | | | 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
* Add some dsputil functions useful for AAC decoderMåns Rullgård2009-09-22
| | | | Originally committed as revision 19955 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Allow arch-specific mdct code to request interleaving of cos/sin tablesMåns Rullgård2009-09-21
| | | | Originally committed as revision 19939 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | Originally committed as revision 19865 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move per-arch fft init bits into the corresponding subdirsMåns Rullgård2009-09-15
| | | | Originally committed as revision 19864 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Add two more sizes to ff_sine_windows[] and also pad it with NULLs soVitor Sessak2009-09-15
| | | | | | | | that FF_ELEMS(ff_sine_windows[x]) == 1 << x. Fix issue 1384. Originally committed as revision 19862 to svn://svn.ffmpeg.org/ffmpeg/trunk
* ARM: NEON optimised MDCTMåns Rullgård2009-09-11
| | | | Originally committed as revision 19819 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Prepare for optimised forward MDCT implementationsMåns Rullgård2009-09-11
| | | | | | | | | 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
* ARM: NEON optimised FFT and MDCTMåns Rullgård2009-09-10
| | | | | | | | Vorbis and AC3 ~3x faster. Parts by Naotoshi Nojiri, naonoj gmail Originally committed as revision 19806 to svn://svn.ffmpeg.org/ffmpeg/trunk
* ff_sine_windows table contains only constant data, too.Reimar Döffinger2009-09-06
| | | | Originally committed as revision 19785 to svn://svn.ffmpeg.org/ffmpeg/trunk
* The ff_cos_tabs table itself is constant, too, so mark it as such.Reimar Döffinger2009-09-06
| | | | Originally committed as revision 19784 to svn://svn.ffmpeg.org/ffmpeg/trunk
* One declaration of mm_flags is enoughMåns Rullgård2009-08-29
| | | | Originally committed as revision 19740 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move declarations of some mmx functions to dsputil_mmx.hMåns Rullgård2009-08-29
| | | | Originally committed as revision 19739 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move DECLARE_ALIGNED_8 definition next to DECLARE_ALIGNED_16Måns Rullgård2009-08-29
| | | | Originally committed as revision 19738 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Make DECLARE_ALIGNED_8 align to 8 bytes, never to 16Måns Rullgård2009-08-28
| | | | | | | | | 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
* Mark parameter src of vector_clipf() as constVitor Sessak2009-08-27
| | | | Originally committed as revision 19729 to svn://svn.ffmpeg.org/ffmpeg/trunk
* SSE optimized vector_clipf(). 10% faster TwinVQ decoding.Vitor Sessak2009-08-27
| | | | Originally committed as revision 19728 to svn://svn.ffmpeg.org/ffmpeg/trunk
* idct_dc for VC-1/WMV3 decoder; ~11% faster decoding overall.Jason Garrett-Glaser2009-06-16
| | | | | | | | | 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
* Support for getting (i)MDCT output multiplied by a constant scaling factor.Siarhei Siamashka2009-05-16
| | | | | | | | 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
