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	013202d720	Simplify intra4x4_pred_mode_cache init. Originally committed as revision 22054 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
Michael Niedermayer	9127a369ad	Replace /2 by faster >>1 as the mvd values are now all positive. Originally committed as revision 22013 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	5c34e36a23	Remove unused variable. Seems i forgot to commit this. Originally committed as revision 22012 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	dd3475682e	Remove unused variable, fixes warnings of the type: libavcodec/h264.h:816: warning: unused variable `mb_xy' Originally committed as revision 21941 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	19769ece3b	H264: use alias-safe macros This eliminates all aliasing violation warnings in h264 code. No measurable speed difference with gcc-4.4.3 on i7. Originally committed as revision 21881 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	69a28f3e2b	Move predict_field_decoding_flag() from h264.h to .c as its only used there and belongs there as well. Originally committed as revision 21861 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	69cc31832f	Move check for and call of predict_field_decoding_flag() from the mb code to the row code. This function would only be needed on a MB basis for MBAFF+FMO Originally committed as revision 21860 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	c1bb66ac19	Split setting neighboring MBs from fill_decode_caches() no speed change. Originally committed as revision 21842 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	2dc380ca8e	Store sub_mb_type in direct_cache/direct_table. This is equal complexity but could be more usefull. Originally committed as revision 21821 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	3d2c3ef4b4	Remove slice_table checks from decode_cabac_mb_cbp_luma() and set left/top_cbp so these checks arent needed. Originally committed as revision 21819 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	e916764675	Direct temporal skiped MBs dont need fill_decode_caches() at all so dont call it for them. Originally committed as revision 21816 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	bb770c5b52	Merge (IS_SKIP(mb_type) \|\| IS_DIRECT(mb_type) Originally committed as revision 21812 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	2e4362af14	Skiped MBs dont need the cbp stuff so skip initing that. Originally committed as revision 21811 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	e2b28acf89	Also skip direct/mvd_cache init for skiped blocks. Odd thing is i thought ive tryed this already and it failed previously. Originally committed as revision 21809 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	8a3b90686d	Remove an apparently unneeded && !FRAME_MBAFF. This should speed the affected cases (MBAFF temporal direct MBs) up. Originally committed as revision 21686 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
