Christophe Gisquet	110d0cdc9d	rv40dsp x86: MMX/MMX2/3DNow/SSE2/SSSE3 implementations of MC Code mostly inspired by vp8's MC, however: - its MMX2 horizontal filter is worse because it can't take advantage of the coefficient redundancy - that same coefficient redundancy allows better code for non-SSSE3 versions Benchmark (rounded to tens of unit): V8x8 H8x8 2D8x8 V16x16 H16x16 2D16x16 C 445 358 985 1785 1559 3280 MMX* 219 271 478 714 929 1443 SSE2 131 158 294 425 515 892 SSSE3 120 122 248 387 390 763 End result is overall around a 15% speedup for SSSE3 version (on 6 sequences); all loop filter functions now take around 55% of decoding time, while luma MC dsp functions are around 6%, chroma ones are 1.3% and biweight around 2.3%.

Christophe GISQUET	e75d1d4f73	dsputil x86: revert a test back to its previous value Commit `356ee8d` caused the initial inversion. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Mans Rullgard	2bcbd98459	Remove lowres video decoding This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	95510be8c3	avcodec: remove AVCodecContext.dsp_mask This removes all references to AVCodecContext.dsp_mask and marks it for eviction at the next version bump. It has been superseded by av_set_cpu_flag_mask() which, unlike this field, works everywhere. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Diego Biurrun	3816642eab	dsputil_mmx: Surround QPEL macros by "do { } while (0);" blocks. This makes them safe to use in non-fully braced if-blocks and similar.	13 years ago
Mans Rullgard	356ee8d7de	x86: clean up ff_dsputil_init_mmx() This splits ff_dsputil_init_mmx() into multiple functions, one for each MMX/SSE level, somewhat simplifying the nested conditions. Signed-off-by: Mans Rullgard <mans@mansr.com> Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Martin Storsjö	9cf0841ef3	dsputil: Add ff_ prefix to the dsputil_init functions Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Christophe Gisquet	6b03900382	x86 dsputil: provide SSE2/SSSE3 versions of bswap_buf While pshufb allows emulating bswap on XMM registers for SSSE3, more shuffling is needed for SSE2. Alignment is critical, so specific codepaths are provided for this case. For the huffyuv sequence "angels_480-huffyuvcompress.avi": C (using bswap instruction): ~ 55k cycles SSE2: ~ 40k cycles SSSE3 using unaligned loads: ~ 35k cycles SSSE3 using aligned loads: ~ 30k cycles Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Ronald S. Bultje	e92003514d	png: move DSP functions to their own DSP context.	13 years ago
Ronald S. Bultje	c3af52fa8b	dsputil: use vertical component for drawing bottom edge. Current code only writes 8 pixels of vertical edge for YUV422, which causes MC artifacts when subsequent frames use data from that edge.	13 years ago
Diego Biurrun	88b9735753	build: conditionally compile x86 H.264 chroma optimizations	13 years ago
Justin Ruggles	395f2e70dd	dsputil: use movups instead of movdqu in ff_emu_edge_core_sse() This allows emulated_edge_mc_sse() and gmc_sse() to be used under AV_CPU_FLAG_SSE.	13 years ago

Diego Biurrun	65083b4911	dsputil: remove disabled code	14 years ago
Mans Rullgard	710b8df949	dsputil: remove ff_emulated_edge_mc macro used in one place This macro can cause problems in conjunction with the bitdepth template expansion. It was presumably added to keep source compatibility when high bitdepth support was added. However, emulated_edge_mc is a dsputil pointer and should not be called directly, so there is little reason to keep such a macro. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Oskar Arvidsson	19a0729b4c	Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 decoder. This patch lets e.g. dsputil_init chose dsp functions with respect to the bit depth to decode. The naming scheme of bit depth dependent functions is <base name>_<bit depth>[_<prefix>] (i.e. the old clear_blocks_c is now named clear_blocks_8_c). Note: Some of the functions for high bit depth is not dependent on the bit depth, but only on the pixel size. This leaves some room for optimizing binary size. Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
