      Drop support for CONFIG_EMULATE_HARDWARE · c6a48a25
      Sebastien Alaiwan authored
      This experiment complexifies DSP function dispatch, without bringing
      any real value (it's non-normative arbitrary behaviour).
      Moreover, it only has an effect on obsolete transforms, the new ones
      don't implement this mechanism.

      Fix encoder use of 16-bit operating path · 374a5907
      Sebastien Alaiwan authored
      When compiled with --disable-lowbitdepth, the decoder uses the generic
      16-bit operating path, regardless of the input video profile.
      The encoder should also use the generic 16-bit operating path if the
      low-bitdepth operating path has been disabled at build time.

      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.

      bitstream-debug: Merge queue_pop and queue_push · 2f905d26
      Fergus Simpson authored
      The bitstream_queue_pop and bitstream_queue_push functions were
      implemented twice each, one implementation for CONFIG_DAALA_EC being set
      and for it not being set. This could cause issues with debugging since
      there's two potential paths, meaning breakpoints and edits need to be
      inserted twice.
      
      The functions were already minimally different, so this patch merges the
      implementation pairs to simplify the code.

      Fix some rdopt bugs in ext-inter · cb03dc34
      David Barker authored
      * Refactor write_inter_mode and cost_mv_ref slightly
      
      * In handle_inter_mode: When discount_newmv_test returns 1,
        ext-inter is enabled, and we're costing up a compound mode,
        we would previously call cost_mv_ref with mode=NEARESTMV and
        comp_pred=1. But this is inconsistent when ext-inter is enabled!
      
        Fix this by changing the behaviour of cost_mv_ref to (effectively)
        derive comp_pred from the mode passed in, and switch to
        mode=NEAREST_NEARESTMV in the above case.
      
      * Fix incorrect motion vector costing for some compound modes
      
      * Fix a case where compound blocks were mis-costed. This primarily
        affects ext-inter *without* wedge or compound-segment enabled,
        but should still have some small impact when those experiments
        are enabled.
      
        The cause of this is that we only spend bits to send the
        interinter compound type if is_any_masked_compound_used(bsize)
        returns true. But the rdopt loop forgot to check this condition
        in one case.

      Retune CDEF dering threshold adjustment · fade4637
      Steinar Midtskogen authored
      Change the adjustment range from [50% ... 300%] to [25% ... 100%].
      Adjustments above 100% were very rare, and capping the adjustment at
      100% adds SIMD optimisation opportunities.  And lowering the other end
      to 25% seems to help compresson slightly.

      Don't export kMinCompressedSize. · 19944291
      Ralph Giles authored
      kMinCompressedSize was defined as a global constant, so it
      was exported by default and possibly causing duplicate
      symbol issues for applications. In particular, libvpx also
      exports this symbol.
      
      Instead, move the definition into the only function which
      references is. As a local variable it is hidden from the
      linker and not part of the global symbol table.

      unify the intra prediction angle options for different block sizes · c81ea6e0
      Ryan Lei authored
      this change unifies the intra prediction angles so that 8x8 block has
      the same number of angles and angle steps as 16x16 and 32x32 blocks.
      the benefit is that HW implementation can have the same logic to
      handle all block sizes. otherwise, prediction angles for 8x8 is
      different from other block sizes, which requies special logic.
