* 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>
* Remove unneeded add bias from 3 functions.Justin Ruggles2011-01-31
| | | | | | | | DSPContext.vector_fmul_window() DCADSPContext.lfe_fir() SynthFilterContext.synth_filter_float() Signed-off-by: Mans Rullgard <mans@mansr.com>

|
* Optimize C version of ff_emulated_edge_mc().Ronald S. Bultje2011-01-28
| | | | | From ~780 cycles to 551 cycles, mostly just by using libc memcpy() instead of manually shuffling individual bytes around.

* Remove unneeded #includeJustin Ruggles2011-01-09
| | | | Originally committed as revision 26272 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Reimplement ff_img_copy_plane() as av_image_copy_plane() in libavcore,Stefano Sabatini2010-09-07
| | | | | | and deprecate the old function. Originally committed as revision 25064 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove duplicate definitions of fullpel MC functionsMåns Rullgård2010-08-25
| | | | | | | This removes duplicated definitions of 8x8 and 16x16 fullpel MC functions with various names reducing dsputil.o by 8k on x86_64. Originally committed as revision 24933 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move vp6_filter_diag4() from DSPContext to VP56DSPContext.Ronald S. Bultje2010-08-25
| | | | Originally committed as revision 24921 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move cavs dsp functions to their own structMåns Rullgård2010-08-03
| | | | Originally committed as revision 24685 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Make ff_inverse stay with libavutil, and optional copy it to libavcodec.Diego Pettenò2010-07-21
| | | | | | | | | | | | | | | | | | | The ff_inverse table is used by FASTDIV macro, defined in libavutil, but up to now the table was defined only in libavcodec. After this change, the main copy of ff_inverse is part of libavutil (just like FASTDIV), but if CONFIG_SMALL is unset, then a different copy is made available to libavcodec, to avoid the performance penalty of using an external look up table. Dynamic linking works, because the libraries are linked with -Bsymbolic, so the local copy of the symbol has priority over the external; static linking works because the table is on a standalone object file in both libraries, so the linker is able to discard one of the two. Tested on Linux/x86-64 and Mac OS X/x86-64. Originally committed as revision 24383 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Add av_ prefix to bswap macrosMåns Rullgård2010-07-10

* Fix grammar errors in documentationMåns Rullgård2010-06-30
| | | | Originally committed as revision 23904 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Set rv34 (0,0) subpel mc functions to the optimised h264 onesMåns Rullgård2010-06-28
| | | | Originally committed as revision 23845 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Add const to some pointer parameters.Eli Friedman2010-06-27
| | | | | | Patch by Eli Friedman, eli D friedman A gmail Originally committed as revision 23826 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Make VP8 DSP functions take two stridesJason Garrett-Glaser2010-06-25
| | | | | | | This isn't useful for the C functions, but will allow re-using H and V functions for HV functions without adding separate H and V wrappers. Originally committed as revision 23782 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Native VP8 decoder.David Conrad2010-06-22
| | | | | | Patch by David Conrad <lessen42 gmail com> and myself. Originally committed as revision 23719 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Add const to ff_emulated_edge_mcDavid Conrad2010-05-27
| | | | Originally committed as revision 23348 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Add more const to _l4 pixel functionsDavid Conrad2010-05-27
| | | | Originally committed as revision 23347 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-20
| | | | | | | | Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk
* vp3: DC-only IDCTDavid Conrad2010-04-17
| | | | | | 2-4% faster overall decode Originally committed as revision 22896 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move H264 dsputil functions into their own structMåns Rullgård2010-03-16
| | | | | | | | | | | This moves the H264-specific functions from DSPContext to the new H264DSPContext. The code is made conditional on CONFIG_H264DSP which is set by the codecs requiring it. The qpel and chroma MC functions are not moved as these are used by non-h264 code. Originally committed as revision 22565 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Separate DWT from snow and dsputilMåns Rullgård2010-03-14
| | | | | | | | This moves the DWT functions from snow.c and dsputil.c to a file of their own. A new struct, DWTContext, holds the function pointers previously part of DSPContext. Originally committed as revision 22522 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Add some required castsMåns Rullgård2010-03-11
| | | | | | | | These casts are correct and safe. The pointers are guaranteed to have proper alignment, and aliasing is not a problem with character types. Originally committed as revision 22446 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move ff_spatial_dwt() prototype to snow.hMåns Rullgård2010-03-06
| | | | Originally committed as revision 22265 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move some dsp func prototypes to dsputil.h; they are defined in dsputil.cMåns Rullgård2010-03-06
| | | | Originally committed as revision 22264 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move some VC1 dsp prototypes to dsputil.h; they are defined in dsputil.cMåns Rullgård2010-03-06
| | | | | | Also fix function definitions to match prototypes (missing const). Originally committed as revision 22263 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move prototypes for various dsputil init functions to dsputil.hMåns Rullgård2010-03-06

| | | | Originally committed as revision 22260 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove DECLARE_ALIGNED_{8,16} macrosMåns Rullgård2010-03-06
| | | | | | | These macros are redundant. All uses are replaced with the generic DECLARE_ALIGNED macro instead. Originally committed as revision 22233 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Bink video decoderKostya Shishkov2010-02-21

| | | | Originally committed as revision 21866 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Simplify some declarations of aligned arraysMåns Rullgård2010-02-17
| | | | | | If DECLARE_ALIGNED_16 works on uint64_t it will work smaller types too. Originally committed as revision 21863 to svn://svn.ffmpeg.org/ffmpeg/trunk
* The SSSE3 version of dct_quantize in mpegvideo_mmx_template.c needsReimar Döffinger2010-01-22
| | | | | | | inv_zigzag_direct16 16-byte aligned, so mark it appropriately. Fixes encoder crashes e.g. with MPlayer's -vf lavc. Originally committed as revision 21389 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move array specifiers outside DECLARE_ALIGNED() invocationsMåns Rullgård2010-01-22

* Mark the h264 c loop filter as av_always_inline av_flatten to make sure itsMichael Niedermayer2010-01-19
| | | | | | | all inlined, its small and horizontal & vertical versions are build out of them. no change as gcc already did this. Originally committed as revision 21333 to svn://svn.ffmpeg.org/ffmpeg/trunk
* skip outer pixels if possible in h264_loop_filter_luma_c().Michael Niedermayer2010-01-19
| | | | | | overall 3.7% faster loop filtering (C version only) Originally committed as revision 21332 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Implement alpha channel decoding for BGR HuffYUV.Alexander Strange2010-01-14
| | | | | | | Since BGR24 is decoded as BGR32, fill its alpha channel with 255 using the appropriate predictors. Originally committed as revision 21211 to svn://svn.ffmpeg.org/ffmpeg/trunk

* refactor and optimize scalarproductLoren Merritt2009-12-05
| | | | | | | | 29-105% faster apply_filter, 6-90% faster ape decoding on core2 (Any x86 other than core2 probably gets much less, since this is mostly due to ssse3 cachesplit avoidance and I haven't written the full gamut of other cachesplit modes.) 9-123% faster ape decoding on G4.
