* Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 ↵Oskar Arvidsson2011-05-10
| | | | | | | | | | | | | | | | | 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>

* H.264: split luma dc idct out and implement MMX/SSE2 versionsJason Garrett-Glaser2011-01-14
| | | | | | | | | | 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
* 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

* 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

* Rename FF_MM_ symbols related to CPU features flags as AV_CPU_FLAG_Stefano Sabatini2010-09-04

* 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

* 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
