Michael Niedermayer	37a9719a97	2 cpu cycles faster context calculation for decode_cabac_intra_mb_type() Originally committed as revision 21845 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	5806e8cd1f	Drop a few redundant slice_num checks. Originally committed as revision 21844 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	053074276b	Drop compute_mb_neighbors() and move fill_decode_neighbors() up to take its role. Should be faster as this is a strict code removial. Originally committed as revision 21843 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	cf55f59d5e	Simplify decode_cabac_mb_intra4x4_pred_mode(). same speed Originally committed as revision 21839 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	f4060611e9	Merge decode_cabac_mb_type_b() into calling code. This avoids a conditional branch and is about 3 cpu cyclues faster. Originally committed as revision 21838 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	64dd1b0a1d	Merge the single line function decode_cabac_mb_transform_size() into the calling code. 8 cpu cycles faster Originally committed as revision 21828 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	8b38d10761	indent Originally committed as revision 21827 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	f4b8b82514	Merge decode_cabac_mb_dqp() with surronding code. ~20 cpu cycles faster Originally committed as revision 21826 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	a59b9ee33d	Set sub_mb_type in direct_cache instead of just the direct flag. Simpler, cleaner and faster. Originally committed as revision 21822 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	2773920698	Optimize decode_cabac_field_decoding_flag(). ~4 cpu cycles faster Originally committed as revision 21447 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	7231ccf4d5	Cosmetic, get rid of &x[0] Originally committed as revision 21309 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	f432b43b08	Split fill_caches() between filter and decoder. Originally committed as revision 21271 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	c988f97566	Rearchitecturing the stiched up goose part 1 Run loop filter per row instead of per MB, this also should make it much easier to switch to per frame filtering and also doing so in a seperate thread in the future if some volunteer wants to try. Overall decoding speedup of 1.7% (single thread on pentium dual / cathedral sample) This change also allows some optimizations to be tried that would not have been possible before. Originally committed as revision 21270 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	ddd60f28d8	Replace cabac checks in inline functions from h264.h with constants. No benchmark because its just replacing variables with litteral constants (so no risk for slowdown outside gcc silliness) and i need sleep. Originally committed as revision 21237 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	cc51b28299	Split cabac decoding code out of h264.c. not slower according to benchmarks. Originally committed as revision 21181 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
