Diego Biurrun	1a094af638	fft: Split MDCT bits off from FFT	9 years ago
Diego Biurrun	97aec6e75e	fft: arm: Drop unnecessary #include, add missing ones	9 years ago
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
Carl Eugen Hoyos	cf36180143	Only set accelerated arm fft functions if fft is enabled. Fixes lavc compilation (linking) for configurations without fft. Reported-by: tyler wear Tested-by: Gavin Kinsey	12 years ago
Mans Rullgard	92dad6687f	arm: fix use of uninitialised value in ff_fft_fixed_init_arm() When initialising an FFTContext for a plain FFT, mdct_bits is not set and can contain a garbage value. Since nbits is always valid and for MDCT operation is mdct_bits - 2 checking this instead avoids using an uninitialised value while having the same effect.

Mans Rullgard	d526c5338d	ARM: allow runtime masking of CPU features This allows masking CPU features with the -cpuflags avconv option which is useful for testing different optimisations without rebuilding. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Mans Rullgard	4538729afe	Move sine windows to a separate file These windows do not really belong in fft/mdct files and were easily confused with the similarly named tables used by rdft. 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
Måns Rullgård	9275438a19	Clean up av_get_cpu_flag() Instead of defining functions in per-arch header files included by the main cpu.c, define them normally and call them from the generic one. Originally committed as revision 25084 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	c6c98d0897	Move mm_support() from libavcodec to libavutil, make it a public function and rename it to av_get_cpu_flags(). Originally committed as revision 25076 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Diego Biurrun	a6493a8fbd	Rename libavcodec/i386/ --> libavcodec/x86/. It contains optimizations that are not specific to i386 and libavutil uses this naming scheme already. Originally committed as revision 16270 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Loren Merritt	5d0ddd1a9f	split-radix FFT c is 1.9x faster than previous c (on various x86 cpus), sse is 1.6x faster than previous sse. Originally committed as revision 14698 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Diego Biurrun	245976da2a	Use full path for #includes from another directory. Originally committed as revision 13098 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Ramiro Polla	40d0e665d0	Do not misuse long as the size of a register in x86. typedef x86_reg as the appropriate size and use it instead. Originally committed as revision 13081 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Ronald S. Bultje	b550bfaa61	Add libavcodec to compiler include flags in order to simplify header include paths in the source files. mostly from a patch by Ronald S. Bultje, rbultje ronald.bitfreak net Originally committed as revision 9034 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Diego Biurrun	b78e7197a8	Change license headers to say 'FFmpeg' instead of 'this program/this library' and fix GPL/LGPL version mismatches. Originally committed as revision 6577 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Loren Merritt	1e4ecf26f5	ff_fft_calc_3dn/3dn2/sse: convert intrinsics to inline asm. 2.5% faster fft, 0.5% faster vorbis. Originally committed as revision 6023 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Zuxy Meng	82eb4b0f1b	3DNow! & Extended 3DNow! versions of FFT Patch by Zuxy Meng, zuxy <<dot>> meng >>at<< gmail <<dot>> com Minor non-functional diff-related fixes by me. Originally committed as revision 5125 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
