2015-06-05avcodec/rdft: Use more specific error codesMichael Niedermayer
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* commit '096a1d5b46391f65dfd0bee6292e9962f53bd7c8': rdft: Move some variables into a separate block Merged-by: Michael Niedermayer <michaelni@gmx.at>
2014-09-05rdft: Move some variables into a separate blockDiego Biurrun
This avoids an unused variable warning with hardcoded tables.

2011-03-20Move dct and rdft definitions to separate filesMans Rullgard
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>
2011-03-19fft: remove inline wrappers for function pointersMans Rullgard
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>
2011-03-19Replace FFmpeg with Libav in licence headersMans Rullgard

Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net> (cherry picked from commit d625a32d6ba0405e6da061991dfd90f6da2a3b7a)

2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun
Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-23ARM: NEON optimised RDFTMåns Rullgård
Originally committed as revision 22641 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-21rdft: reorder functions to avoid static prototypeMåns Rullgård
Originally committed as revision 22610 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-21Call rdft by function pointerMåns Rullgård
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
2010-03-09Replace many includes of libavutil/common.h with what is actually neededMåns Rullgård
This reduces the number of false dependencies on header files and speeds up compilation. Originally committed as revision 22407 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-08Give RDFT types more meaningful namesMåns Rullgård
Originally committed as revision 22290 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-07Make some functions staticMåns Rullgård
These functions are not used outside their respective files, and they lack a prototype in a header. Originally committed as revision 22259 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-03-06Move FFT parts from dsputil.h to fft.hMåns Rullgård
Originally committed as revision 22235 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-11-05Add ff_init_ff_cos_tabs function and use it in rdft.c to ensure that theReimar Döffinger
necessary ff_cos_tabs tables are initialized. Fixes issue 1507 (QDM2 broken since r20237 without hardcoded tables). Originally committed as revision 20464 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-11-04Pad ff_cos_tabs and ff_sin_tabs so that index n points to the table for n bits.Reimar Döffinger
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
2009-10-15Add support for hardcoded ff_sin_* tables.Reimar Döffinger
Originally committed as revision 20244 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-10-15Move/add COSTABLE/SINTABLE macros to dsputil to add extern definitionsReimar Döffinger
for ff_cos_* and ff_sin_* without introducing too much code duplication. Originally committed as revision 20243 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-10-15Do not initialize ff_cos_* tables again in rdft_init, they are alreadyReimar Döffinger
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
2009-09-06The pointers in ff_sin_tabs themselves are constant, so mark them accordingly.Reimar Döffinger
Originally committed as revision 19783 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-02-01Use full internal pathname in doxygen @file directives.Diego Biurrun
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
2009-01-30Add the rdft family of transforms (fft/ifft of an all real sequence) to dsputil.Alex Converse
Originally committed as revision 16864 to svn://svn.ffmpeg.org/ffmpeg/trunk
