Mans Rullgard	0b6f973635	h264: use asm cabac reader under a generic condition This removes a dependency on implementation details from generic code and allows easy addition of the equivalent optimisation for other architectures than x86. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Justin Ruggles	713548cbad	x86: lavc: use %if HAVE_AVX guards around AVX functions in yasm code. This is needed for older versions of yasm/nasm that do not support AVX. Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago

Justin Ruggles	95a98ab3f0	ac3dsp: simplify x86 versions of ac3_max_msb_abs_int16 Simplifies the code by using cpuflags and a new macro. Also fixes the invalid use of the MMX2 pshufw operation in the MMX-only function.	13 years ago

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%.

Roland Scheidegger	9b9df1cdff	h264: new assembly version of get_cabac for x86_64 with PIC This adds a hand-optimized assembly version for get_cabac much like the existing one, but it works if the table offsets are RIP-relative. Compared to the non-RIP-relative version this adds 2 lea instructions and it needs one extra register. get_cabac() gets about 40% faster, for an overall speedup of about 5%. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Roland Scheidegger	14e9ffc1e4	h264: use one table instead of several for cabac functions The reason is this is easier for PIC code (in particular on darwin...). Keep the old names as pointers (static in cabac_functions.h so gcc knows these are just immediate offsets) so the c code can nicely stay the same (alternatively could use offsets directly in the functions needing the tables). This should produce the same code as before with non-pic and better code (confirmed) with pic. The assembly uses the new table but still won't work for PIC case. Signed-off-by: Ronald S.

Roland Scheidegger	444f47b55c	h264: (trivial) remove unneeded macro argument in x86/cabac.h 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
Ronald S. Bultje	87a246341b	h264: use proper PROLOGUE statement for a function using 8 registers. Fixes crashes when using biweight on win64.	13 years ago
Ronald S. Bultje	b089ca871a	dsputil: fix optimized emu_edge function on Win64. Recent register allocation changes (x86inc.asm update) changed the register order and thus opcodes for the inner loops. One of them became >128bytes, which confuses other parts of this function where it jumps to fixed-offset positions to extend the edge by fixed amounts. A simple register change fixes this.	13 years ago
Justin Ruggles	de7f22ab0c	ac3dsp: call femms/emms at the end of float_to_fixed24() for 3DNow and SSE Fixes ac3-encode and eac3-encode FATE test failures with SSE2 disabled. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Ronald S. Bultje	76538d7a78	h264: fix 10bit biweight functions after recent x86inc.asm fixes. This should have been updated in the x86inc.asm update, but was accidently forgotten.	13 years ago

Christophe GISQUET	2130bd8f5b	rv40dsp x86: use only one register, for both increment and loop counter Around 10 cycles faster for luma. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Christophe GISQUET	272b252c01	rv40dsp: implement prescaled versions for biweight. Quite often, the original weights are multiple of 512. By prescaling them by 1/512 when they are computed (once per frame), no intermediate shifting is needed, and no prescaling on each call either. The x86 code already used that trick.
