David Conrad	eb6a6cd788	vp3: DC-only IDCT 2-4% faster overall decode Originally committed as revision 22896 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	4693b031a3	Move H264 dsputil functions into their own struct 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	15 years ago
Måns Rullgård	05aec7bb87	Separate DWT from snow and dsputil 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	15 years ago
Måns Rullgård	2023cfea0f	Add some required casts 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	15 years ago
Måns Rullgård	98713e55b4	Move ff_spatial_dwt() prototype to snow.h Originally committed as revision 22265 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	965363f81a	Move some dsp func prototypes to dsputil.h; they are defined in dsputil.c Originally committed as revision 22264 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	4f602a0415	Move some VC1 dsp prototypes to dsputil.h; they are defined in dsputil.c Also fix function definitions to match prototypes (missing const). Originally committed as revision 22263 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	7de9da9ba7	Move prototypes for various dsputil init functions to dsputil.h Originally committed as revision 22261 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	3da1180409	Move some prototypes from dsputil.c to reasonable header files Originally committed as revision 22260 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	84dc2d8afa	Remove DECLARE_ALIGNED_{8,16} macros 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	15 years ago
Kostya Shishkov	342c7dfdbb	Bink video decoder Originally committed as revision 21937 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	40d1122752	Use LOCAL_ALIGNED macro for local arrays Originally committed as revision 21866 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	2480c390bd	Simplify some declarations of aligned arrays 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	15 years ago
Reimar Döffinger	e62a55b92e	The SSSE3 version of dct_quantize in mpegvideo_mmx_template.c needs 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	15 years ago
Måns Rullgård	c67278098d	Move array specifiers outside DECLARE_ALIGNED() invocations Originally committed as revision 21377 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	3f50965b28	Mark the h264 c loop filter as av_always_inline av_flatten to make sure its 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	15 years ago
Michael Niedermayer	c9640c17ac	skip outer pixels if possible in h264_loop_filter_luma_c(). overall 3.7% faster loop filtering (C version only) Originally committed as revision 21332 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alexander Strange	f267d3ac75	Implement alpha channel decoding for BGR HuffYUV. 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	15 years ago

Diego Biurrun	af818f7a66	Add required header #includes for mpegvideo.h and config.h. Originally committed as revision 20974 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Loren Merritt	b1159ad928	refactor and optimize scalarproduct 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. Originally committed as revision 20739 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Loren Merritt	e17ccf60fe	huffyuv: add some const qualifiers Originally committed as revision 20290 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Justin Ruggles	f4d608e344	add CONFIG_LPC to the build system for lpc dsputil functions. fixes build problems when lpc.c is not compiled. Originally committed as revision 20285 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Justin Ruggles	fde82ca7e4	Move autocorrelation function from flacenc.c to lpc.c. Also rename the corresponding dsputil functions and remove their dependency on the FLAC encoder. Fixes Issue1486. Originally committed as revision 20266 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alexander Strange	f076fe4422	Remove a meaningless 'inline' from add_hfyu_left_prediction_bgr32_c(). Originally committed as revision 20260 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Måns Rullgård	952e872198	Drop unused args from vector_fmul_add_add, simpify code, and rename The src3 and step arguments to vector_fmul_add_add() are always zero and one, respectively. This removes these arguments from the function, simplifies the code accordingly, and renames the function to better match the new operation. Originally committed as revision 20061 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Måns Rullgård	95d36bdbc3	dsputil: declare some arrays 16-byte aligned These arrays are passed to functions for which we promise 16-byte alignment, so make sure we fulfil that promise. Originally committed as revision 19716 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	64e657fd2c	100l, inv_zigzag_direct16 must be aligned to 16 bytes for dct_quantize_SSE2 (which uses movdqa to xmm1 on inv_zigzag_direct16). Originally committed as revision 19711 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Diego Biurrun	9be6f0d2f8	Do not check for both CONFIG_VC1_DECODER and CONFIG_WMV3_DECODER, the former depends upon the latter. Originally committed as revision 19533 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	99e5a9d1ea	Do not redundantly check for both CONFIG_THEORA_DECODER and CONFIG_VP3_DECODER. The Theora decoder depends on the VP3 decoder. Originally committed as revision 19492 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
