Ronald S. Bultje	62844c3fd6	h264: Integrate clear_blocks calls with IDCT The non-intra-pcm branch in hl_decode_mb (simple, 8bpp) goes from 700 to 672 cycles, and the complete loop of decode_mb_cabac and hl_decode_mb (in the decode_slice loop) goes from 1759 to 1733 cycles on the clip tested (cathedral), i.e. almost 30 cycles per mb faster.

Diego Biurrun	88bd7fdc82	Drop DCTELEM typedef It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	12 years ago

Diego Biurrun	26301caaa1	x86: mmx2 ---> mmxext in asm constructs	12 years ago
Diego Biurrun	588fafe7f3	x86: MMX2 ---> MMXEXT in macro names	12 years ago
Diego Biurrun	04581c8c77	x86: yasm: Use complete source path for macro helper %includes This is more consistent with the way we handle C #includes and it simplifies the build system.	12 years ago
Diego Biurrun	6860b4081d	x86: include x86inc.asm in x86util.asm This is necessary to allow refactoring some x86util macros with cpuflags.	12 years ago
Mans Rullgard	a3df4781f4	x86: add colons after labels nasm prints a warning if the colon is missing. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago

Henrik Gramner	729f90e268	x86inc improvements for 64-bit Add support for all x86-64 registers Prefer caller-saved register over callee-saved on WIN64 Support up to 15 function arguments Also (by Ronald S. Bultje) Fix up our asm to work with new x86inc.asm. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Ronald S. Bultje	ce1e250ee9	h264: manually save/restore XMM registers for functions using INIT_MMX. On Win64, these registers are callee-save, so not saving/restoring them correctly is a violation of ABI and can lead to crashes or corrupt data.	13 years ago
Ronald S. Bultje	3b15a6d742	config.asm: change %ifdef directives to %if directives. This allows combining multiple conditionals in a single statement.	13 years ago

Ronald S. Bultje	b2c087871d	Move x86util.asm from libavcodec/ to libavutil/. This allows using it in swscale also.	13 years ago
Ronald S. Bultje	3a39195b1d	Move x86inc.asm to libavutil/. This allows using it in libswscale/ also.	13 years ago
Jason Garrett-Glaser	a3bf7b864a	H.264: tweak some other x86 asm for Atom	13 years ago
Jason Garrett-Glaser	c90b94424c	4:4:4 H.264 decoding support Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.	14 years ago
Jason Garrett-Glaser	504811baea	Roll back 4:4:4 H.264 for now Needs some ARM/PPC asm modifications.	14 years ago
Jason Garrett-Glaser	c9c493872c	4:4:4 H.264 decoding support Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.	14 years ago
Daniel Kang	348493db60	Update 8-bit H.264 IDCT function names to reflect bit-depth. Signed-off-by: Ronald S. Bultje <rbultje@google.com>	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

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
Reimar Döffinger	02b424d9c8	Add d suffix to movd target register to make it work with nasm. Originally committed as revision 25206 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Ronald S. Bultje	ae11291865	Unroll loop in h264_idct_add16intra_sse2(). Basically identical to r25171, this inlines scan8[] and removes loop setup. 15% faster, 0.4% overall. See "[PATCH] unroll loop in h264_idct_add8_sse2()" thread on ML. Originally committed as revision 25172 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Ronald S. Bultje	4bca677494	Unroll loop in h264_idct_add8_sse2(). This means we can inline scan8[] in the code directly also and remove loop setup. 20% faster in function, 0.8% overall. See "[PATCH] unroll loop in h264_idct_add8_sse2()" thread on ML. Originally committed as revision 25171 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Ronald S. Bultje	1d16a1cf99	Rename h264_idct_sse2.asm to h264_idct.asm; move inline IDCT asm from h264dsp_mmx.c to h264_idct.asm (as yasm code). Because the loops are now coded in asm instead of C, this is (depending on the function) up to 50% faster for cases where gcc didn't do a great job at looping. Since h264_idct_add8() is now faster than the manual loop setup in h264.c, in-asm idct calling can now be enabled for chroma as well (see r16207). For MMX, this is 5% faster. For SSE2 (which isn't done for chroma if h264.c does the looping), this makes it up to 50% faster. Speed gain overall is ~0.5-1.0%.
