Justin Ruggles	e9da9a3111	lavr: x86: improve non-SSE4 version of S16_TO_S32_SX macro Removes a false dependency on existing contents of the 2nd dst register, giving better performance for OOE.	12 years ago
Justin Ruggles	2f096bb10e	lavr: add x86-optimized mixing functions Adds optimized functions for mixing 3 through 8 input channels to 1 and 2 output channels in fltp or s16p format with flt coeffs.	12 years ago
Ronald S. Bultje	30b45d9c38	x86inc: automatically insert vzeroupper for YMM functions.	12 years ago
Justin Ruggles	0dadf9d1e9	lavr: x86: add missing vzeroupper in ff_mix_1_to_2_fltp_flt()	12 years ago
Justin Ruggles	6410397600	lavr: resampling: add support for s32p, fltp, and dblp internal sample formats Based partially on implementation by Michael Niedermayer <michaelni@gmx.at> in libswresample in FFmpeg. See commits: `7f1ae79d38` `24ab1abfb6`	13 years ago
Justin Ruggles	372647aed0	lavr: resampling: add filter type and Kaiser window beta to AVOptions	13 years ago
Justin Ruggles	8ca08066fc	lavr: Use AV_SAMPLE_FMT_NONE to auto-select the internal sample format Also make this the default value.	13 years ago
Justin Ruggles	db0e7bd0bd	lavr: mix: validate internal sample format in ff_audio_mix_init()	13 years ago
Diego Biurrun	2047e40e6e	Clarify Doxygen comment for FF_API_* #defines.	13 years ago
Justin Ruggles	acd9948e74	lavr: x86: fix ff_conv_fltp_to_flt_6ch function prototypes Changed to match the number of parameters in conv_func_interleave(), which is how they are called. The change isn't strictly necessary because the 4th parameter is not used, but the code is clearer if they match.	13 years ago
Justin Ruggles	14a34d90ad	lavr: x86: merge some branches	13 years ago

Justin Ruggles	1168e29df1	lavr: Add x86-optimized function for s16 to s32 conversion	13 years ago
Justin Ruggles	f61ce90caa	lavr: add x86-optimized functions for mixing 1-to-2 s16p with flt coeffs	13 years ago
Justin Ruggles	29f7490c46	lavr: add x86-optimized functions for mixing 1-to-2 fltp with flt coeffs	13 years ago
John Stebbins	3971be0eb5	Add Dolby/DPLII downmix support to libavresample Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Justin Ruggles	b75726cb79	lavr: add x86-optimized function for mixing 2 to 1 s16p with q8 coeffs	13 years ago
Justin Ruggles	c140fb2cbc	lavr: add x86-optimized functions for mixing 2 to 1 s16p with float coeffs	13 years ago
Justin Ruggles	8dfc122719	lavr: add C functions for mixing 2 to 1 channels with s16p format	13 years ago
Justin Ruggles	5cc6d5244d	lavr: replace the SSE version of ff_conv_fltp_to_flt_6ch() with SSE4 and AVX The current SSE version is slower than the MMX version on Athlon64 and Sandy Bridge, but the SSE4 and AVX versions are faster on Sandy Bridge.	13 years ago
Anton Khirnov	9684341346	lavr: do not try to copy to uninitialized output audio data. This would happen at least when lavr is used as a fifo with no conversion.	13 years ago
Anton Khirnov	0982b0a431	lavr: make avresample_read() with NULL output discard samples.	13 years ago
Diego Biurrun	dbe6ba55a3	build: cosmetics: Add missing end-of-line backslashes to item lists.	13 years ago
Justin Ruggles	4010d724e1	lavr: use 8.8 instead of 10.6 as the 16-bit fixed-point mixing coeff type	13 years ago
Reimar Döffinger	e5b7d7773a	Fix compilation with YASM/NASM without AVX support. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Justin Ruggles	c8af852b97	Add libavresample This is a new library for audio sample format, channel layout, and sample rate conversion.	13 years ago
