James Almer	c8467abbad	x86/rv34dsp: add ff_rv34_idct_dc_add_sse2 Also disable ff_rv34_idct_dc_add_mmx on x86_64 as the presence of sse2 is guaranteed in such builds. Signed-off-by: James Almer <jamrial@gmail.com>	8 years ago
Thilo Borgmann	d814a839ac	Reinstate proper FFmpeg license for all files.	12 years ago
Diego Biurrun	88bd7fdc82	Drop DCTELEM typedef It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	12 years ago
Diego Biurrun	26301caaa1	x86: mmx2 ---> mmxext in asm constructs	12 years ago
Diego Biurrun	04581c8c77	x86: yasm: Use complete source path for macro helper %includes This is more consistent with the way we handle C #includes and it simplifies the build system.	12 years ago
Diego Biurrun	6860b4081d	x86: include x86inc.asm in x86util.asm This is necessary to allow refactoring some x86util macros with cpuflags.	12 years ago
Mans Rullgard	2b140a3d09	x86: use 32-bit source registers with movd instruction yasm tolerates mismatch between movd/movq and source register size, adjusting the instruction according to the register. nasm is more strict. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Ronald S. Bultje	76888c64b0	rv34: port x86 SIMD to cpuflags.	13 years ago
Christophe Gisquet	fe5ed69dc7	rv34dsp x86: implement MMX2 inverse transform 141 cycles down to 51. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Reimar Döffinger	7e62315c91	Use correct register size. Fixes compilation with NASM. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	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
Reimar Döffinger	83b12c16af	Use correct register size, fixes compilation with NASM. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	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.
