2016-02-17Better workaround for Bug 1089.Alex Converse
Don't initialize first pass costs for a number of symbols where first pass probabilities aren't initialized. This brings a 1.22x first pass speedup. https://bugs.chromium.org/p/webm/issues/detail?id=1089 Change-Id: I97438c357bd88f52f5a15c697031cf0c3cc8f510

2015-10-29Make the zero handling in extend_to_full_distribution more explicit.Alex Converse
The old workaround "p = 0 ? 0 : p -1" is misleading. ?: happens before = assigning back to p truncates to one byte. Therefore it is equivalent to (p - 1) & 0xFF, but the check just exists to work around a first pass bug, so let's make the work around more clear. https://bugs.chromium.org/p/webm/issues/detail?id=1089 Change-Id: I587c44dd61c1f3767543c0126376f881889935af
2015-10-28Revert "Replace the zero handling in extend_to_full_distribution."Alex Converse
This reverts commit 7f56cb29787b187c8cb1b778918ca3b80184c804. It causes uninitialized reads in the first pass setting up later cost tables. Change-Id: I2df498df3f5c03eff359f79edf045aed0c618dc9

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
2015-07-20vpx_dsp/bitreader.h: vp9_->vpx_Yaowu Xu
Replace vp9_ in names to vpx_ as they are not codec specific. Change-Id: I2e583aa63dee769353ada4b42417aa15c4074ebb
2015-06-12vp9_entropy: delete vp9_coefmodel_tree[]James Zern
it's been unused since: 4ac6a25 Moving vp9_tree_probs_from_distribution() to encoder. Change-Id: Ieae65864277fc3dbe993c5c08d75c6c5fcaa3a2d
2015-04-28vpx_mem: remove vpx_memcpyJames Zern
vestigial. replace instances with memcpy() which they already were being defined to. Change-Id: Icfd1b0bc5d95b70efab91b9ae777ace1e81d2d7c
2015-03-31Move vp9_coef_con_tree to common/hui su
This tree should be defined in common/, as it is needed for both encoder and decoder. Change-Id: I4f5cbc80025cf2ced14182c98f7c82dc7d0f87db
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

2013-11-13Simplifies band-getting with a static arrayDeb Mukherjee
Simplifies the code by implementing band mapping with static arrays. A lot of the code complexity introduced in a previous patch disappears. Change-Id: Ia3fac36e594fb5ad2d55ae141c58bba4c55c2d28
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
2013-11-01Removing '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
2013-10-16Merge "Using constants instead of plain numbers."Dmitry Kovalev
2013-10-15Updated encoder to handle intra-only framesAlexander Voronov
Updated the encoder to handle frames that are coded intra-only. Intra-only frames must be non-showable, that is, the "show frame" flag must be set to 0 in the frame header. Tested by forcing the ARF frames to be coded intra- only. Note: The rate control code will need to be modified to account for intra-only frames better than they are currently handled. Change-Id: I6a9dd5337deddcecc599d3a44a7431909ed21079

2013-10-07Moving all scan/iscan code into separate vp9_scan.{h, c} files.Dmitry Kovalev
Now we have entropy code separate from scan/iscan code. The next step in future is to move iscan code from common part to the encoder. Change-Id: Id9732f7d80aec00af35c1d58d1137c4c96c91451

Fixes a warning on MSVS 2012 where the alignment of vp9_default_iscan_8x8 didn't match between its declaration and definition. Change-Id: I1466a15635f4b22594d705d570b7e399bfb6cf21
2013-07-25General cleanups.Dmitry Kovalev
