2018-01-18clang-format v5.0.0 vp9/Johann
Remove trailing commas to keep multiple elements on one line. Add blank lines to prevent comments from being treated as blocks. clang-format guards for struct with a comment in the middle. Change-Id: I3bcb8313ae8aaf69179249a13b4087b1272cdbc0

2015-07-20vpx_dsp/prob.h: vp9_ -> vpx_Yaowu Xu
change prefix vp9_ to vpx_ for non codec specific functions and data structures. Change-Id: I97c7e6422eceea99212b93f4942bc2187763a07c
2015-07-06vp9_entropymv: remove vp9_get_mv_mag()James Zern
inline the code directly in read_mv_component(), the only place where it was being used; this removes a function call in a hot function Change-Id: I66f99c0c9ce3bc310101dbca4a470f023cc6fb55
2015-01-23Replace divide with look-upYaowu Xu
This commit replaces an integer divide with a table-lookup. It is to improve decoding speed, and at the same time, to reduce possible complications with a bug in AMD Family 12h processors: "665 Integer Divide Instruction May Cause Unpredictable Behavior" Change-Id: I678b707a538798a923850bac467e66e847e6def7
2014-10-22vp9_ethread: allocate frame contexts outside VP9_COMMON structYunqing Wang
This patch allocated frame contexts outside VP9_COMMON. This allows multiple threads to share the same copy of frame contexts, and reduces the overhead. It also guarantees the correct update of these contexts during bitstream packing. This patch doesn't change encoding result. Change-Id: Ic181a2460b891d1d587278a6d02d8057b9dbd353

2013-11-05Localizing NEARESTMV special cases in the code.Dmitry Kovalev
Removing special case handling from vp9_tree_probs_from_distribution(), tree_merge_probs(), and vp9_tokens_from_tree_offset() functions. Replacing inter_mode_offset() function with macro INTER_OFFSET which is used now for vp9_inter_mode_tree definition. Change-Id: Iff75a1499d460beb949ece543389c8754deaf178
2013-11-04Unified approach for backward probability update.Dmitry Kovalev
Replacing update_mode_probs() and adapt_probs() with tree_merge_probs(). Change-Id: I50b2c968d67c9265f5216c700cbeba25fb014654
2013-11-01Removing 'new' probability calculation from convert_distribution().Dmitry Kovalev
We don't have to calculate 'new' probability in convert_distribution() because it is enough to calculate only 'new' counters which could be used to calculate probability if necessary. That's why removing a lot of unused temporary probability arrays and reducing number of get_binary_prob() calls. Change-Id: I4e14eb7203d1ace61bbddefd6b9b6326be83ba63
2013-10-18vp9 dec/com: only update frame counts when necessaryJames Zern

2013-07-23Moving counts from FRAME_CONTEXT to new struct FRAME_COUNTS.Dmitry Kovalev
Counts are separate from frame context. We have several frame contexts but need only one copy of all counts. Change-Id: I5279b0321cb450bbea7049adaa9275306a7cef7d
2013-07-19Removing pre probabilities from FRAME_CONTEXT.Dmitry Kovalev

2013-07-08Inline vp9_get_mv_joint().Ronald S. Bultje
Encode time for first 50 frames of bus (speed 0) @ 1500kbps goes from 2min10.9 to 2min10.5, i.e. 0.3% faster overall, basically because we prevent the call overhead. Change-Id: I1eab1a95dd3eae282f9b866f1f0b3dcadff073d5
