Diego Biurrun	08dba0e1c3	x86: mpegvideoenc: Remove some remnants of the long-gone libmpeg2 IDCT	11 years ago
Diego Biurrun	3bfdee00cd	x86: dcadsp: Fix linking with yasm and optimizations disabled Some optimized functions reference optimized symbols, so the functions must be explicitly disabled when those symbols are unavailable.	11 years ago
Diego Biurrun	3741aa37c2	x86: cabac: Use correct #includes to make header compile standalone	11 years ago
Christophe Gisquet	4cb6964244	dcadec: simplify decoding of VQ high frequencies The vector dequantization has a test in a loop preventing effective SIMD implementation. By moving it out of the loop, this loop can be DSPized. Therefore, modify the current DSP implementation. In particular, the DSP implementation no longer has to handle null loop sizes. The decode_hf implementations have following timings: For x86 Arrandale: C SSE SSE2 SSE4 win32: 260 162 119 104 win64: 242 N/A 89 72 The arm NEON optimizations follow in a later patch as external asm. The now unused check for the y modifier in arm inline asm is removed from configure.	11 years ago
Christophe Gisquet	08e3ea60ff	x86: synth filter float: implement SSE2 version Timings for Arrandale: C SSE win32: 2108 334 win64: 1152 322 Factorizing the inner loop with a call/jmp is a >15 cycles cost, even with the jmp destination being aligned. Unrolling for ARCH_X86_64 is a 20 cycles gain. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	11 years ago
Christophe Gisquet	ad507d7907	x86: dcadsp: implement SSE lfe_dir Results for Arrandale/Windows: 32: 1670 -> 316 64: 728 -> 298 Signed-off-by: Janne Grunau <janne-libav@jannau.net>	11 years ago

Janne Grunau	5c1c6e8226	dca: include dcadsp.h in {arm,x86}/dca.h for checkheaders	11 years ago
Janne Grunau	0cffd6fff5	x86: use the inline int8x8_fmul_int32 only if inline SSE2 is availbale Fixes compilation with MSVC. Also does not rely on on earlier config.h include but include it directly.	11 years ago
Christophe Gisquet	5b59a9fc61	x86: dcadsp: implement int8x8_fmul_int32 For the callable function (as opposed to the inline one): C SSE SSE2 SSE4 Win32: 47 42 29 26 Win64: 30 33 25 23 The SSE version is neither compiled nor set for ARCH_X86_64, as the inlinable function takes over.

Ronald S. Bultje	9ee9c679a7	x86: videodsp: Fix a bug in a %if statement where we used '%%' instead of '&&'. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	11 years ago
Ronald S. Bultje	51daafb02e	x86: videodsp: Properly mark sse2 instructions in emulated_edge_mc as such. Should fix crashes or corrupt output on pre-SSE2 CPUs when they were using SSE2-code (e.g. AMD Athlon XP 2400+ or Intel Pentium III) in hfix or hvar single-edge (left/right) extension functions.

Anton Khirnov	dfc50ac85e	x86: mpegvideo: move denoise_dct asm to mpegvideoenc This function is encoding-only. Signed-off-by: Diego Biurrun <diego@biurrun.de>	11 years ago
Diego Biurrun	4958f35a2e	dsputil: Move apply_window_int16 to ac3dsp The (optimized) functions are used nowhere else.	11 years ago
Diego Biurrun	3d7c84747d	x86: Initialize mmxext after amd3dnow optimizations The mmxext optimizations should be at least equally fast if available and amd3dnow optimizations are being deprecated. Thus the former should override the latter, not the other way around.	11 years ago
Diego Biurrun	7ffaa19570	dsputil: x86: Move ff_inv_zigzag_direct16 table init to mpegvideo The table is MMX-specific and used nowhere else.	11 years ago

Ronald S. Bultje	458446acfa	lavc: Edge emulation with dst/src linesize Allow supporting files for which the image stride is smaller than the maximum block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.	11 years ago
Diego Biurrun	19e30a58fc	Deprecate obsolete XvMC hardware decoding support XvMC has long ago been superseded by newer acceleration APIs, such as VDPAU, and few downstreams still support it. Furthermore XvMC is not implemented within the hwaccel framework, but requires its own specific code in the MPEG-1/2 decoder, which is a maintenance burden.	11 years ago

Henrik Gramner	bbe4a6db44	x86inc: Utilize the shadow space on 64-bit Windows Store XMM6 and XMM7 in the shadow space in functions that clobbers them. This way we don't have to adjust the stack pointer as often, reducing the number of instructions as well as code size. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago

Diego Biurrun	2ddb35b911	x86: dsputil: Separate ff_add_hfyu_median_prediction_cmov from dsputil_mmx The function does not depend on MMX and compilation without MMX enabled fails if the function is compiled conditional on MMX availability.	11 years ago
