Ronald S. Bultje	66c6b5e2a5	Revert `2a1f431d38`, it broke H264 lossless.	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	5657d14094	H.264: switch to x264-style tracking of luma/chroma DC NNZ Useful so that we don't have to run the hierarchical DC iDCT if there aren't any coefficients. Opens up some future opportunities for optimization as well. Originally committed as revision 26337 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
Eli Friedman	9049fa5479	Add av_unused to decode_mb_skip declaration to fix the following warning: libavcodec/h264.h:1260: warning: ‘decode_mb_skip’ defined but not used patch by Eli Friedman, eli.friedman gmail com Originally committed as revision 24069 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Måns Rullgård	49bd8e4b84	Fix grammar errors in documentation Originally committed as revision 23904 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Howard Chu	82f1ffc7ba	Cleanup prev commit, flag variable should start with 0 Originally committed as revision 23364 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Howard Chu	05e953193d	Factorize ff_h264_decode_extradata(). Patch by Howard Chu, hyc highlandsun com Originally committed as revision 23340 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. 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	15 years ago
Diego Biurrun	d02bb3ecf1	Move static function fill_filter_caches() from h264.h to h264.c. The function is only used within that file, so it makes sense to place it there. This fixes many warnings of the type: h264.h:1170: warning: ‘fill_filter_caches’ defined but not used Originally committed as revision 22876 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	1052b76f0f	Fix implicit weight for b frames in mbaff. Originally committed as revision 22733 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Benoit Fouet	32e543f866	Replace @returns by @return . Originally committed as revision 22729 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	404793f4ac	H264: fix signed overflow in constant multiplication This fixes libavcodec/h264.h:1100: warning: integer overflow in expression Originally committed as revision 22558 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
Michael Niedermayer	38768cb70a	Port Optimizations about *_type init from decode to filter code. 1 cpu cycle faster Originally committed as revision 22193 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	bd8868e092	Move all context fields that are not used in the mb and block layers to the end of the structure. 4 cpu cycles faster in 3k cpu cycles Originally committed as revision 22181 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	65f3c029b9	remove unused left_border field from context. Originally committed as revision 22179 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	af2b0df40f	Note about luma/chroma_weight tables and their datatype. Originally committed as revision 22177 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	f57880d244	Another 3 useless zeroing instructions. Originally committed as revision 22162 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	16b802fe93	Load the whole left side of mv&ref only when needed. 30 cpu cycles faster Originally committed as revision 22161 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	ce9c691616	Merge h->slice_table[left_xy[0/1] ] checks, 4 cpu cycles speedup Originally committed as revision 22086 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	82fb5bb2ee	Split *_type setting up, 4 cpu cycles faster. Originally committed as revision 22085 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	cf41a02b1b	Only load the topleft mv/ref when the topright is unavailable. 8 cpu cycles faster. Originally committed as revision 22079 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	cf7b67bc40	Remove some useless operations from the code setting left_cbp. maybe 0.5 cpu cycles faster Originally committed as revision 22078 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	59b5370f02	Simplify code to set cbp_* this seems 1 cpu cycle slower even though we practically just remove code. Speed loss seems caused by the merge of if(left_type), iam commiting this anyway as i cant imagine this to be anything but compiler messup. Originally committed as revision 22073 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	747db4e31a	Move init of right side of ref_cache from fill_caches() to init_the_darn_decoder(). Originally committed as revision 22071 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	77c6edb846	Remove 3 mv_cache zeroing instructions that zeroed the right side. This seems unneeded as nothing seems to ever set it to non zero values. Originally committed as revision 22070 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	8f8497ae78	Remove useless check of the 2 left MBs of a pair being in the same slice. Originally committed as revision 22069 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	6e2fe0f20a	Remove unneeded line of code from the neighbor setting code in h264. Originally committed as revision 22067 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	358b5b1a59	Get rid of mb2b8_xy and b8_stride, change arrays organized based on b8_stride to ones based on mb_stride in h264. about 20 cpu cycles faster overall per MB Originally committed as revision 22065 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	5e350863cc	Store data in direct_table interleaved. seems 20cpu cycles faster Originally committed as revision 22055 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	662a5b2370	Reorder intra4x4_pred_mode so that we can read/write 4 values at once. 3-7 cpu cycles faster Originally committed as revision 22053 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	5b0fb5244d	Store intra4x4_pred_mode per row only. about 5 cpu cycles slower in the local code but should be overall faster due to reduced cache use. (my sample though has too few intra4x4 blocks for this to be meassureable easily either way) Originally committed as revision 22052 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	c2186cbddc	unroll tiny and trivial loop. Same speed but clearer. Originally committed as revision 22051 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	e1c88a2138	Cut the size of mvd_table by yet another factor of 2. The code read/write code itself was 1 cycle faster, overall its likely more due to cache effects Originally committed as revision 22048 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	d43c192236	Keep mvd_table values of only 2 mb rows. Originally committed as revision 22047 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	b5bd070029	Change mvd_cache & mvd_table to 8bit, this is overall a bit faster for high resolution videos. about 20cycles faster per MB for cathederal. Originally committed as revision 22038 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
