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

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	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	599fe45b8d	Split fill_caches() between loopfilter & decode, the 2 no longer where common enough to justify the messy interleaving. Originally committed as revision 21469 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	dfe4dc154b	use left_xy[1] in mbaff QP loop filter check, this improves the amount that can be skiped. Originally committed as revision 21465 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
