Justin Ruggles	32f8fb8ecf	Add float_interleave() to FmtConvertContext with x86-optimized versions. Partially based on patches by clsid2 in ffdshow-tryout. ff_float_interleave6() x86 improvements by Loren Merrit.	14 years ago
Daniel Kang	d0005d347d	Modify x86util.asm to ease transitioning to 10-bit H.264 assembly. Arguments for variable size instructions are added to many macros, along with other various changes. The x86util.asm code was ported from x264. Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Gil Pedersen	257de5fb25	h264dsp_mmx: Add #ifdefs around some mmxext functions on x86_64. This fixes linking errors due to undefined symbols on x86_64 OS X. Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Diego Biurrun	888fa31eca	Fix FSF address copy paste error in some license headers.	14 years ago

Ronald S. Bultje	86b29553f8	h264dsp_mmx: place bracket outside #if/#endif block. Should fix compile on systems missing yasm/nasm.	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

Justin Ruggles	e6e9823488	Add apply_window_int16() to DSPContext with x86-optimized versions and use it in the ac3_fixed encoder.	14 years ago
Mans Rullgard	0aded9484d	Move dct and rdft definitions to separate files This leaves fft.h with only the core FFT and MDCT definitions thus making it more managable. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	0f999cfddb	ac3enc: add float_to_fixed24() with x86-optimized versions to AC3DSPContext and use in scale_coefficients() for the floating-point AC-3 encoder.	14 years ago
Justin Ruggles	79414257e2	mathops: fix MULL() when the compiler does not inline the function. If the function is not inlined, an immmediate cannot be used for the shift parameter, so the %cl register must be used instead in that case. This fixes compilation for x86-32 using gcc with --disable-optimizations.	14 years ago
Justin Ruggles	aaff3b312e	mathops: change "g" constraint to "rm" in x86-32 version of MUL64(). The 1-arg imul instruction cannot take an immediate argument, only a register or memory argument.	14 years ago
Justin Ruggles	b181b8fb96	mathops: convert MULL/MULH/MUL64 to inline functions rather than macros. This fixes unexpected name collisions that were occurring with variables declared within the macros. It also fixes the fate-acodec-ac3_fixed regression test on x86-32.	14 years ago
Justin Ruggles	f1efbca5e9	ac3enc: add SIMD-optimized shifting functions for use with the fixed-point AC3 encoder.	14 years ago

Justin Ruggles	1f004fc512	ac3dsp: Change punpckhqdq to movhlps in ac3_max_msb_abs_int16(). Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Justin Ruggles	fbb6b49dab	ac3enc: Add x86-optimized function to speed up log2_tab(). AC3DSPContext.ac3_max_msb_abs_int16() finds the maximum MSB of the absolute value of each element in an array of int16_t. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Loren Merritt	e6b1ed693a	FFT: factor a shuffle out of the inner loop and merge it into fft_permute. 6% faster SSE FFT on Conroe, 2.5% on Penryn. Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>	14 years ago
Justin Ruggles	dda3f0ef48	Add x86-optimized versions of exponent_min(). Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Ronald S. Bultje	17cf7c68ed	Fix ff_emu_edge_core_sse() on Win64. Fix emu_edge_v_extend_15 to be <128 bytes on Win64, by being more strict on the size of registers and which registers are being used for operations where multiple are available. This fixes segfaults in emulated_edge() function calls on Win64.	14 years ago
Justin Ruggles	c73d99e672	Separate format conversion DSP functions from DSPContext. This will be beneficial for use with the audio conversion API without requiring it to depend on all of dsputil. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Alex Converse	770c410fbb	Fix ff_imdct_calc_sse() on gcc-4.6 Gcc 4.6 only preserves the first value when using an array with an "m" constraint. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Ronald S. Bultje	81f2a3f4ff	Implement a SIMD version of emulated_edge_mc() for x86. From ~550 cycles (C version) to 170 (SSE/x86-64), 206 (MMX/x86-32) and 196 (SSE2/x86-32) cycles.	14 years ago

Ronald S. Bultje	b9c7f66e6d	Fix horizontal/horizontal_up 8x8l intra prediction x86/simd functions. The original functions did not work correctly for edge pixels, e.g. when CODEC_FLAG_EMU_EDGE is set, leading to corrupt output in e.g. VLC. Based on a patch by Daniel Kang <daniel d kang gmail com>.

Ronald S. Bultje	1b3e43e4fd	Fix overflow in pred16x16_plane x86 simd code. Fixes issue 2547. Originally committed as revision 26381 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Ronald S. Bultje	ec3233a855	Fix ff_pw_3 alignment. Originally committed as revision 26344 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	19fb234e4a	H.264: split luma dc idct out and implement MMX/SSE2 versions About 2.5x the speed. NOTE: the way that the asm code handles large qmuls is a bit suboptimal. If x264-style dequant was used (separate shift and qmul values), it might be possible to get some extra speed. Originally committed as revision 26336 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
