Christophe Gisquet	566b7a20fd	x86: float dsp: butterflies_float SSE 97c -> 49c Some codecs could benefit from more unrolling, but AAC doesn't.	12 years ago
Christophe Gisquet	1a4007964c	x86: float dsp: butterflies_float SSE 97c -> 49c Some codecs could benefit from more unrolling, but AAC doesn't. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Diego Biurrun	b6649ab503	cosmetics: Remove unnecessary extern keywords from function declarations	12 years ago
Ronald S. Bultje	42d3246948	floatdsp: move vector_fmul_reverse from dsputil to avfloatdsp. Now, nellymoserenc and aacenc no longer depends on dsputil. Independent of this patch, wmaprodec also does not depend on dsputil, so I removed it from there also.	12 years ago
Ronald S. Bultje	55aa03b9f8	floatdsp: move vector_fmul_add from dsputil to avfloatdsp.	12 years ago
Ronald S. Bultje	d56668bd80	floatdsp: move scalarproduct_float from dsputil to avfloatdsp. This makes the aac decoder and all voice codecs independent of dsputil.	12 years ago
Martin Storsjö	973b4d44f1	float_dsp: Add #ifdef HAVE_INLINE_ASM around vector_fmul_window This fixes builds on 64bit MSVC. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Justin Ruggles	947f933687	x86: float_dsp: add SSE version of vector_fmul_scalar()	12 years ago
Diego Biurrun	e0c6cce447	x86: Replace checks for CPU extensions and flags by convenience macros This separates code relying on inline from that relying on external assembly and fixes instances where the coalesced check was incorrect.	12 years ago

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

Måns Rullgård	2f0c136e1f	Check whether IBM or Apple PPC assembler syntax is used This checks which assembler syntax is supported and defines macros for register names accordingly. Originally committed as revision 23952 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Stefano Sabatini	987903826b	Globally rename the header inclusion guard names. Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Måns Rullgård	3540b950ec	add missing #include "common.h" to libavutil headers Originally committed as revision 12502 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
