Mans Rullgard	5cc2600964	dsputil: create 16/32-bit dctcoef versions of some functions High bitdepth H.264 needs 32-bit transform coefficients, whereas dnxhd does not. This creates a conflict with the templated functions operating on DCTELEM data. This patch adds a field allowing the caller to choose the element size in dsputil_init() and adds the required functions. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	0a72533e98	jfdctint: add 10-bit version Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	7b4ee3a21d	Remove h264_lowres_idct_put/add functions Use of these has been broken ever since the h264 idct was changed to always use transposed inputs. Furthermore, they were only ever used if some other non-default idct was requested. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	710b8df949	dsputil: remove ff_emulated_edge_mc macro used in one place This macro can cause problems in conjunction with the bitdepth template expansion. It was presumably added to keep source compatibility when high bitdepth support was added. However, emulated_edge_mc is a dsputil pointer and should not be called directly, so there is little reason to keep such a macro. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	6054cd25b4	ac3enc: add int32_t array clipping function to DSPUtil, including x86 versions.	14 years ago

Jason Garrett-Glaser	c90b94424c	4:4:4 H.264 decoding support Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.	14 years ago
Jason Garrett-Glaser	504811baea	Roll back 4:4:4 H.264 for now Needs some ARM/PPC asm modifications.	14 years ago

Ronald S. Bultje	e973557211	Move emms_c() from libavcodec to libavutil.	14 years ago
Oskar Arvidsson	19a0729b4c	Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 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>	14 years ago

Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	381d37fda9	dsputil: add bswap16_buf() 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>	14 years ago
Johan Andersson	21de920472	Update the url to the site website and change ffmpeg-devel to libav-devel Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago

Ronald S. Bultje	12802ec060	dsputil: move VC1-specific stuff into VC1DSPContext.	14 years ago
Justin Ruggles	c73d99e672	Separate format conversion DSP functions from DSPContext. 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>	14 years ago

Justin Ruggles	6eabb0d3ad	Change DSPContext.vector_fmul() from dst=dstsrc to dest=src0src1. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	96aad41e81	Make LOCAL_ALIGNED macro fully C99 compatible 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>	14 years ago
Justin Ruggles	56f8952b25	Move lpc_compute_autocorr() from DSPContext to a new struct LPCContext. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Jason Garrett-Glaser	2a1f431d38	H.264/SVQ3: make chroma DC work the same way as luma DC 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	14 years ago
Jason Garrett-Glaser	290fabc684	Port SVQ3 to use the new mb_luma_dc method of storing luma DC coefficients. 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	14 years ago
Jason Garrett-Glaser	2e18660115	Fix SVQ3 Regression in r26336-7. Originally committed as revision 26341 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Jason Garrett-Glaser	19fb234e4a	H.264: split luma dc idct out and implement MMX/SSE2 versions 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	14 years ago
Stefano Sabatini	c6c98d0897	Move mm_support() from libavcodec to libavutil, make it a public function and rename it to av_get_cpu_flags(). Originally committed as revision 25076 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	9686abb826	Reimplement ff_img_copy_plane() as av_image_copy_plane() in libavcore, and deprecate the old function. Originally committed as revision 25064 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	3d1b1caa6b	Remove duplicate definitions of fullpel MC functions 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	15 years ago
