* ac3enc: Add x86-optimized function to speed up log2_tab().Justin Ruggles2011-02-13
| | | | | | | 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>
* FFT: factor a shuffle out of the inner loop and merge it into fft_permute.Loren Merritt2011-02-13
| | | | | | 6% faster SSE FFT on Conroe, 2.5% on Penryn. Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>
* Add x86-optimized versions of exponent_min().Justin Ruggles2011-02-10
| | | | Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* Fix ff_emu_edge_core_sse() on Win64.Ronald S. Bultje2011-02-08
| | | | | | | 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.
* Separate format conversion DSP functions from DSPContext.Justin Ruggles2011-02-02
| | | | | | | 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>
* Fix ff_imdct_calc_sse() on gcc-4.6Alex Converse2011-02-02
| | | | | | | Gcc 4.6 only preserves the first value when using an array with an "m" constraint. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Implement a SIMD version of emulated_edge_mc() for x86.Ronald S. Bultje2011-01-31
| | | | | From ~550 cycles (C version) to 170 (SSE/x86-64), 206 (MMX/x86-32) and 196 (SSE2/x86-32) cycles.

* Move lpc_compute_autocorr() from DSPContext to a new struct LPCContext.Justin Ruggles2011-01-21
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* Fix horizontal/horizontal_up 8x8l intra prediction x86/simd functions.Ronald S. Bultje2011-01-19
| | | | | | | | 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>. Signed-off-by: Ronald S. Bultje <rsbultje gmail com>
* Replace ASMALIGN() with .p2alignMans Rullgard2011-01-18
| | | | | This macro has unconditionally used .p2align for a long time and serves no useful purpose.
* x86: remove VLA in ac3_downmix_sseMans Rullgard2011-01-18

* consolidate .gitignore patters into a single fileJanne Grunau2011-01-18

* 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
