* Move static inline function to a macro, so that constant propagation inRonald S. Bultje2010-09-29
| | | | | | | inline asm works for gcc-3.x also (hopefully). Should fix gcc-3.x FATE breakage after r25254. Originally committed as revision 25262 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Merge b_idx and edge variables, and optimize the ASM to directly load variablesRonald S. Bultje2010-09-29
| | | | | | | | from memory locations/offsets depending on b_idx plus constants, rather than having gcc do this. This saves several lea calls and together saves about 10 cycles in h264_loop_filter_strength_mmx2(). Originally committed as revision 25256 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove mv_mask variable. Replace the related pand -1/0 instructions by eitherRonald S. Bultje2010-09-29
| | | | | | | a pxor, or remove the instruction alltogether. Altogether, this saves 1 instruction. Originally committed as revision 25255 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove d_idx as a variable, and instead load it as a constant in the asm.Ronald S. Bultje2010-09-29
| | | | | | | This has no measurable speed effect because the surrounding code doesn't take advantage of this yet. Originally committed as revision 25254 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Unroll inner bidir loop in h264_loop_filter_strength_mmx2(), which gets ridRonald S. Bultje2010-09-29
| | | | | | | of the d_idx variable and therefore allows for future optimizations. No speed difference by this commit itself. Originally committed as revision 25253 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Unloop the outer loop in h264_loop_filter_strength_mmx2(), which allowsRonald S. Bultje2010-09-29
| | | | | | | inlining various constants within the loop code. 20 cycles faster on cathedral sample. Originally committed as revision 25252 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove unused variable.Ronald S. Bultje2010-09-24
| | | | Originally committed as revision 25173 to svn://svn.ffmpeg.org/ffmpeg/trunk
* x86: disable SSE functions using stack when stack is not alignedMåns Rullgård2010-09-21
| | | | | | This fixes crashes with ICC 10.1. Originally committed as revision 25153 to svn://svn.ffmpeg.org/ffmpeg/trunk
* x86: remove hack disabling sse2 h264 loop filter with 32-bit iccMåns Rullgård2010-09-18
| | | | Originally committed as revision 25146 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Rename h264_idct_sse2.asm to h264_idct.asm; move inline IDCT asm fromRonald S. Bultje2010-09-14
| | | | | | | | | | | | | 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%.

* LGPL SSE2 H.264 iDCTJason Garrett-Glaser2010-09-10
| | | | | | | | This leaves no more GPL-only H.264 decoding asm code. Approved by Loren. Originally committed as revision 25092 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move mm_support() from libavcodec to libavutil, make it a publicStefano Sabatini2010-09-08
| | | | | | function and rename it to av_get_cpu_flags(). Originally committed as revision 25076 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Rename FF_MM_ symbols related to CPU features flags as AV_CPU_FLAG_Stefano Sabatini2010-09-04
| | | | | | symbols, and move them from libavcodec/avcodec.h to libavutil/cpu.h. Originally committed as revision 25040 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Port latest x264 deblock asm (before they moved to using NV12 as internalRonald S. Bultje2010-09-03
| | | | | | | format), LGPL'ed with permission from Jason and Loren. This includes mmx2 code, so remove inline asm from h264dsp_mmx.c accordingly. Originally committed as revision 25031 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Rename h264_weight_sse2.asm to h264_weight.asm; add 16x8/8x16/8x4 non-squareRonald S. Bultje2010-09-01
| | | | | | | | biweight code to sse2/ssse3; add sse2 weight code; and use that same code to create mmx2 functions also, so that the inline asm in h264dsp_mmx.c can be removed. OK'ed by Jason on IRC. Originally committed as revision 25019 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Split h264dsp_mmx.c (which was #included in dsputil_mmx.c) in h264_qpel_mmx.c,Ronald S. Bultje2010-09-01
| | | | | | | still #included in dsputil_mmx.c and is part of DSPContext, and h264dsp_mmx.c, which represents H264DSPContext and is now compiled on its own. Originally committed as revision 25018 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Split intra prediction initialization (i.e. assigning of function pointers)Ronald S. Bultje2010-08-30
| | | | | | | into its own file, it doesn't belong in h264dsp_mmx.c (much less so in dsputil_mmx.c). Originally committed as revision 24990 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move H264 chroma MC from inline asm to yasm. This fixes VP3/5/6 and VC-1Ronald S. Bultje2010-08-30

* Split h264dsp and h264pred in configure.Jason Garrett-Glaser2010-08-07
| | | | | | | | | Many H.264 derivatives, like RV40 and VP8, use the H.264 prediction functions but not the weight/loopfilter functions. This should reduce the size of builds with one of these derivatives but without H.264 decoding itself. Originally committed as revision 24741 to svn://svn.ffmpeg.org/ffmpeg/trunk
