Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. 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	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
Måns Rullgård	1366f05978	rdft: reorder functions to avoid static prototype Originally committed as revision 22610 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	2ed6f39944	Replace many includes of libavutil/common.h with what is actually needed 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	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	da0ac0ee64	Make some functions static 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	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
Reimar Döffinger	1ffc6e8327	Add ff_init_ff_cos_tabs function and use it in rdft.c to ensure that the 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	15 years ago
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
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	f470fff323	The pointers in ff_sin_tabs themselves are constant, so mark them accordingly. Originally committed as revision 19783 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. 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	16 years ago
Alex Converse	6860254044	Add the rdft family of transforms (fft/ifft of an all real sequence) to dsputil. Originally committed as revision 16864 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
