* FFT: factor a shuffle out of the inner loop and merge it into fft_permute.Loren Merritt2011-02-13
| | | | | | 6% faster SSE FFT on Conroe, 2.5% on Penryn. Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>
* Mark C base versions of FFT functions static to fft.cDiego Elio Pettenò2011-01-26

* Revert unintended changes to fft.h from r24890.Alex Converse2010-08-23

* aacenc: Rename Psy3gpp* structs to AacPsy*Nathan Caldwell2010-08-23
| | | | | | | | | | 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
* SSE optimized 32-point DCTVitor Sessak2010-07-06

* Remove vestiges of radix-2 FFTMåns Rullgård2010-07-01
| | | | | | Patch (mostly) by Loren Merritt Originally committed as revision 23957 to svn://svn.ffmpeg.org/ffmpeg/trunk
* More mp{1,2,3} 32-point DCT transform to our common DCT framework.Vitor Sessak2010-06-30
| | | | | | Should allow for future SIMD optimizations. Originally committed as revision 23912 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Fix grammar errors in documentationMåns Rullgård2010-06-30
| | | | Originally committed as revision 23904 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove VLA in ff_kbd_window_init, limit window size to 1024Måns Rullgård2010-06-24
| | | | Originally committed as revision 23755 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Implement the discrete sine/cosine transforms DCT-I and DST-IVitor Sessak2010-03-23
| | | | Originally committed as revision 22649 to svn://svn.ffmpeg.org/ffmpeg/trunk
* ARM: NEON optimised RDFTMåns Rullgård2010-03-23
| | | | Originally committed as revision 22641 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Call DCT by function pointer. Needed for any future ASM implementation andVitor Sessak2010-03-21
| | | | | | allows further cleanup. Originally committed as revision 22617 to svn://svn.ffmpeg.org/ffmpeg/trunk
* DCT: remove unused field from contextVitor Sessak2010-03-21
| | | | Originally committed as revision 22615 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Call rdft by function pointerMåns Rullgård2010-03-20
| | | | | | | | | 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
* Create a public API for FFT family of functionsMåns Rullgård2010-03-07
| | | | Originally committed as revision 22291 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Give RDFT types more meaningful namesMåns Rullgård2010-03-07
| | | | Originally committed as revision 22290 to svn://svn.ffmpeg.org/ffmpeg/trunk
