* ac3dsp: simplify x86 versions of ac3_max_msb_abs_int16Justin Ruggles2012-05-15
| | | | | | 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.

* rv40dsp x86: MMX/MMX2/3DNow/SSE2/SSSE3 implementations of MCChristophe Gisquet2012-05-10
| | | | | | | | | | | | | | | | | | | | 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%.

* h264: new assembly version of get_cabac for x86_64 with PICRoland Scheidegger2012-04-28
| | | | | | | | | | 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>
* h264: use one table instead of several for cabac functionsRoland Scheidegger2012-04-28
| | | | | | | | | | | | | 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. Bultje <rsbultje@gmail.com>

* Remove lowres video decodingMans Rullgard2012-04-21
| | | | | | | This feature is complex, of questionable utility, and slows down normal decoding. Signed-off-by: Mans Rullgard <mans@mansr.com>
* avcodec: remove AVCodecContext.dsp_maskMans Rullgard2012-04-21
| | | | | | | | 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>
* h264: use proper PROLOGUE statement for a function using 8 registers.Ronald S. Bultje2012-04-16
| | | | Fixes crashes when using biweight on win64.
* dsputil: fix optimized emu_edge function on Win64.Ronald S. Bultje2012-04-13
| | | | | | | | 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.
* ac3dsp: call femms/emms at the end of float_to_fixed24() for 3DNow and SSEJustin Ruggles2012-04-12

* rv40dsp x86: use only one register, for both increment and loop counterChristophe GISQUET2012-04-10

* rv40dsp: implement prescaled versions for biweight.Christophe GISQUET2012-04-10
| | | | | | | | | | 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.

* sbrdsp.asm: convert all instructions to float/SSE ones.Reimar Döffinger2012-03-07
| | | | | | | | | | | Since the values are floats, using the float operations makes sense, improves performance on some CPUs and makes the code SSE compatible instead of needing SSE2.

* dsputil: remove shift parameter from scalarproduct_int16Christophe GISQUET2012-03-07
| | | | | | | | | There is only one caller, which does not need the shifting. Other use cases are situations where different roundings would be needed. The x86 and neon versions are modified accordingly. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
