Diego Biurrun	794fcf79a8	Rename CONFIG_FFT_FLOAT ---> FFT_FLOAT The define does not originate from configure, so it should not have a name that is CONFIG_-prefixed.	11 years ago
Derek Buitenhuis	479a527955	cos_tablegen: Don't use lrint You cannot count on it being present on all systems, and you cannot include libm.h in a host tool, so just hard code a baseline implementation. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
Janne Grunau	1d01fee980	fix hardcoded tables compililation caused by missing math constants Add -D_XOPEN_SOURCE=600 to host cflags to make the constants in math.h available. Include math.h where necessary and remove redundant M_PI defines.	13 years ago
Diego Biurrun	4887f8245c	Rename costablegen.c ---> cos_tablegen.c. This is consistent with how all other table generation programs are named. Moreover this ensures that the cos table generation program is correctly deleted when cleaning the tree.	14 years ago
Mans Rullgard	272874c9db	Simplify trig table rules This collapses the make rules for the trig tables into a pattern rule. Based on a patch by Diego, modified to avoid using fragile make constructs and allow future addition of fixed-point sin tables. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Biurrun	c98657a215	Remove potentially unstable filenames from comments in generated files.	14 years ago
Mans Rullgard	7087ce08c8	Fixed-point FFT and MDCT	14 years ago
Mans Rullgard	0aded9484d	Move dct and rdft definitions to separate files 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>	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Reimar Döffinger	0209cd0719	Fix --enable-hardcoded-tables compilation: the generate table files now need to include fft.h, not dsputil.h. Originally committed as revision 22278 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	52a4a07778	Fix out-of-tree builds with --enable-hardcoded-tables Originally committed as revision 20404 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	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
