James Almer	d68c05380c	x86: check for AV_CPU_FLAG_AVXSLOW where useful Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
Thilo Borgmann	d814a839ac	Reinstate proper FFmpeg license for all files.	11 years ago
Diego Biurrun	3ac7fa81b2	Consistently use "cpu_flags" as variable/parameter name for CPU flags	12 years ago
Diego Biurrun	b6649ab503	cosmetics: Remove unnecessary extern keywords from function declarations	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

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	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
Justin Ruggles	c8af852b97	Add libavresample This is a new library for audio sample format, channel layout, and sample rate conversion.	13 years ago
Ronald S. Bultje	3ab9a2a557	rv34: change most "int stride" into "ptrdiff_t stride". This prevents having to sign-extend on 64-bit systems with 32-bit ints, such as x86-64. Also fixes crashes on systems where we don't do it and arguments are not in registers, such as Win64 for all weight functions.	13 years ago
Christophe GISQUET	9ba9c34024	rv34: 1-pass inter MB reconstruction Implement 1-pass inverse transform and reconstruction for inter blocks.	13 years ago
Christophe GISQUET	d78062386e	rv34: Intra 16x16 handling Extract processing of intra 16x16 blocks from intra macroblock processing. Also implement a function performing inverse transform and block reconstruction for DC-only blocks in 1 pass instead of 2.	13 years ago
Christophe GISQUET	3faa303a47	rv34: DC-only inverse transform When decoding coefficients, detect whether the block is DC-only, and take advantage of this knowledge to perform DC-only inverse transform. This is achieved by: - first, changing the 108x4 element modulo_three_table into a 108 element table (kind of base4), and accessing each value using mask and shifts. - then, checking low bits for 0 (as they represent the presence of higher frequency coefficients) Also provide x86 SIMD code for the DC-only inverse transform.
