* Move emms_c() from libavcodec to libavutil.Ronald S. Bultje2011-05-24

* 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>

* dsputil: add bswap16_buf()Mans Rullgard2011-03-16
| | | | | | | | There are several places where a buffer is byte-swapped in 16-bit units. This allows them to share code which can be optimised for various architectures. Signed-off-by: Mans Rullgard <mans@mansr.com>

* 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>

* Make LOCAL_ALIGNED macro fully C99 compatibleMans Rullgard2011-01-22
| | | | | | | | | C99 variadic macros require more arguments than there are named parameters in the definition. This means we must use an extra indirection to avoid having two different macros for arrays with one resp more than one dimension. Signed-off-by: Mans Rullgard <mans@mansr.com>

* H.264/SVQ3: make chroma DC work the same way as luma DCJason Garrett-Glaser2011-01-15
| | | | | | | No speed improvement, but necessary for some future stuff. Also opens up the possibility of asm chroma dc idct/dequant. Originally committed as revision 26349 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Port SVQ3 to use the new mb_luma_dc method of storing luma DC coefficients.Jason Garrett-Glaser2011-01-15
| | | | | | | Doesn't help speed as there isn't an asm implementation yet, but consistency is a good thing. Originally committed as revision 26348 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Fix SVQ3Jason Garrett-Glaser2011-01-14
| | | | | | Regression in r26336-7. Originally committed as revision 26341 to svn://svn.ffmpeg.org/ffmpeg/trunk
* 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 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
* 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

* 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
* 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

* 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
* Move DECLARE_ALIGNED_{8,16} macros to mem.hMåns Rullgård2010-03-06
| | | | | | | These macros naturally belong next to the generic DECLARE_ALIGNED macro. Originally committed as revision 22230 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
* Add support for hard-coded MDCT-related ff_sine_windows tables.Reimar Döffinger2010-01-09
| | | | Originally committed as revision 21108 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.
