      intrabc: Add initial skeleton · 28744309
      Alex Converse authored 
      Missing features:
* RDOPT (Forced on for certain blocks)
* Any form of border extension
* Non MI sized right and bottom edges
* MV prediction

Present features:
* Force intrabc for some blocks
* Carry intrabc in the bitstream
* Validate DV is causal
* Reconstruct intrabc block assuming border extension is unnecessary

      Harmonize ext-inter and ref-mv · 3dfba994
      David Barker authored 
      This changes the behavior of the ext-inter compound modes
as follows:
* NEAREST_NEARESTMV, NEAR_NEARMV, NEW_NEWMV, ZERO_ZEROMV
  work the same as the corresponding compound modes without
  ext-inter
* NEAREST_NEWMV and NEW_NEARESTMV keep their current behavior,
  which is to use the first ref-mv candidate pair for their
  particular reference frames
* NEAR_NEWMV and NEW_NEARMV select between the second, third,
  and fourth candidate pairs.
* NEAREST_NEARMV and NEAR_NEARESTMV use the first candidate
  pair for the NEAREST component and the second, third, or
  fourth candidate pair for the NEAR component.

Also do some minor refactoring and fix compile errors
with --enable-ext-inter --disable-ref-mv

      ext_tile: add 2 tile encoding modes · d8cd55f4
      Yunqing Wang authored 
      Added 2 tile encoding modes:
TILE_NORMAL mode supports the large-scale tile coding up to 1024 x 1024
tiles;
TILE_VR mode supports the large-scale tile coding and also the decoding
of a single tile.

TILE_NORMAL mode allows the non-vr content to be encoded in multiple tiles
without using the coding tool that are designed for vr applications.

      Add txk_sel exp · cd9b03fb
      Angie Chiang authored 
      This will separate the transform kernel selection from lv_map
experiment such that we can evaluate each feature's performance
separately

Note that txk_sel is build on top of lv_map

      Adds an option to disable warp when obmc is used with a
global motion neighbor.

      pvq: Remove support for disabling nodesync. · 44bb6d06
      Timothy B. Terriberry authored 
      This was broken by commit 1238137c.

When calling the generic coder with a max, it truncates the CDF, but
then tries to encode/decode with the Q15 entropy coder functions
with built-in adaptation. That causes assertion failures, because the
total probability isn't 32768.

We could fix it by re-scaling the CDF, and then doing adaptation
assuming there was no max, but that requires several special-case
code paths.

Instead, since non-robust streams were the only thing that still
required calling the generic coder with a max, and since the gain
from them is very small (and they require doing more DSP just to be
able to parse the stream), we simply remove the option and force
the use of robust streams all the time.

With robust streams enabled, encoder output should not change, and
all streams should remain decodable without decoder changes.

Thanks to Nathan Egge for reporting the problem.

      Temporarily disable multi-thread loop filter in cb4x4 · 52ece884
      Jingning Han authored 
      The loop filter parameters change due to many experiments. The
multi-thread loop filter is built on certain assumptions that would
require changes in many table contents. Temporarily disable the
multi-thread loop filter pass and only maintain the single frame
reference during the development process.
