- Use Makefile to control the build for highbd_fwd_txfm_sse4.c. - Fixed hybrid transform (HT) types due to recent update. - Added new unit test cases for highbd HT. Change-Id: Ifd768a9b429a8c21ed40c1de8152fb5ac71e2f90

Merge "Highbd fht4x4 SSE4.1 optimization for DCT_DCT mode - Setup function vp10_highbd_fht4x4_sse4_1 for highbd SSE4.1 intrinsics optimization. - Wrote SSE4.1 functions: load_buffer_4x4(), write_buffer_4x4(), and fdct4x4_sse4_1(). - Used logic right shift to avoid coeff memory write/read. - Turned on vp10_highbd_fht4x4_sse4_1 for DCT_DCT mode only. - Improved overall encoding performance >2.3% for 50 frames sequence, park_joy_1080p_12.y4m, in which, --input-bit-depth=12, --bit-depth=12, 50 frames. - Unit test passed." into nextgenv2

Uses 15 frames instead of 30. Also only test speed 0 for VP10. Change-Id: Icace050edd974622d83bdf843058f63bd8d3a84b

This has been ported under ext_partition_types because it is due to be combined with the coding_unit_size experiment which is already being ported under ext_partition Change-Id: I47af869ae123ddf0aa99160dac644059d14266ee

Decompose choose_tx_size_from_rd into three functions that determine the transform coding rd at different stages. Besides the original function, txfm_yrd() calculates the rd for fixed size and type. choose_tx_size_fix_type() fixes the type and searches for the size. It can enable other experiments to do restricted tx searches so as to reduce the impact on speed. Similar refactoring is done for select_tx_type_yrd() in VAR_TX. Performance change in baseline is trivial: 0.014/0.001/-0.020 for lowres/midres/hdres. Change-Id: I2ecbf6066329be088ec1bfb69013b657b14b8afe

This allows sharing more code paths with the rest of the code an allows for easier compatibility with the other experiments. Change-Id: Id288b533805a4d0657ec2f17542f2e6ad23ebdb4

Makes a set of 16 transforms total, adding all 1D combinations of ADST and FlipADST, and removng all DST transforms. lowres, midres both improve by about 0.1% and hdres by -0.378% in BDRATE but with fewer transforms that are also simpler. Further experiments to continue later. Change-Id: I7348a4c0e12078fdea5ae3a2d36a89a319ffcc6e

This buffered ANS coder supports coding the symbols in forward (decode) order. Rather than windowing or growing the buffer, right now this coder merely asserts that the buffer will never overflow. This approach should allow ANS to be used as a drop in replacement for other entropy coders rather than requiring complicated reversal logic throughout the codebase.
