      scaling: Add kf numerator for resize and superres · 87cf61b1
      Fergus Simpson authored
      Adds a separate scale numerator for resize and superres scaling on
      keyframes. They will only use this factor in their respective FIXED
      modes.

      Unify resize and superres denominator constants · bfbf6a59
      Fergus Simpson authored
      RESIZE_SCALE_DENOMINATOR and SUPERRES_SCALE_DENOMINATOR were two
      constants with the same value that did essentially the same thing.
      
      This patch merges the two into SCALE_DENOMINATOR for simplicity's sake.

      frame_superres: Add aomenc argument · c4e78942
      Fergus Simpson authored
      Adds "superres-mode" and "superres-numerator" arguments to configure
      superres scaling.
      
      There are only two modes right now: SUPERRES_FIXED and SUPERRES_DYNAMIC.
      0 sets the fixed mode and 1 sets the dynamic mode.
      
      For the fixed mode superres will scale to the provided numerator where
      possible. The cumulative scale change over resizing and superres is
      limited to 1/2, so it may have to back off.
      
      For the dynamic mode, the provided numerator will be used as the initial
      numerator. Asides from that it's just random for now.

      frame-superres: Pre-encode downscaling · 3502d08b
      Fergus Simpson authored
      Adds handling needed for the pre-encode downscaling for superres
      encoding. Makes use of the existing resizing functionality, just
      adjusting the target resolution after the resize logic and before the
      resize has actually occurred.
      
      Since the upscaling portion of superres is not yet implemented, superres
      scaling is not yet allowed to trigger. The numerator is set to be equal
      to the denominator and the superres_pending flag is not set.

      Add the motion vector unit test · ff4fa068
      Yunqing Wang authored
      This unit test was ported from VP9. To prevent the motion vector out of
      range bug, added a motion vector unit test. In the 4k video encoding,
      always forced to use extreme motion vectors and also encouraged to use
      INTER modes. In the decoding, checked if the motion vector was valid,
      and also checked the encoder/decoder mismatch.

      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.

      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.

      Remove rt deadline. · 8082614e
      Thomas Daede authored
      The "good" speed levels are universally better than the "rt" ones,
      running faster to achieve the same quality.
      
      rt mode also turned off alt refs and lag-in-frames, but these
      are still accessible separately (and the low latency test case
      explicitly sets them).
      
      Some features were used by the rt scale and not the good scale.
      Two additional "good" levels, 7 and 8, were added to accomidate
      these features and not reduce test coverage.

      Implement twopass support for the xiphrc system · 74021a5a
      Rostislav Pehlivanov authored
      This commit implements support for twopass encoding using the xiphrc
      experimental rate control system. Most of the code and logic comes
      from the theora project encoder.
      
      Currently support is limited to the bitrate targeting mode of the
      rate control system and while it does visibly improve quality and does
      bring rate closer to the target than the one pass mode there's still
      tuning and bug fixing to be done.

      Implement a new rate control system · 002e7b7a
      Rostislav Pehlivanov authored
      This commit implements a new rate control system which was ported from
      Daala's rate control system (which was based off of Theora's rate
      control system) to the encoder. Its aim is to address the weaknesses of
      the current rate control system and eventually serve as its replacement.
      
      This is still work in progress. So far this commit only implements
      support for single pass encoding for constant quality and bitrate
      targeting.
      Additional commits which implement two-pass support and the rest to
      match the feature set of the current rate control system are coming
      soon.
      
      The rate control system hasn't been fully tuned (and will likely need
      additional tuning as the encoder's development progresses) and does
      contain some "hacks", to convert the quality to a quantizer value
      (empirical) and to tweak the quantizer in between golden frames (which
      uses some code from the current rate control system as well as code
      which attempts to model what that code does), the latter of which is
      only in the constant quality codepath.
      
      Bitrate targeting works much better than the current rate control
      system's targeting and will actually closely match the rate specified by
      the user without the current rate control system's bursty behaviour.

      Add an experiment to disable lpf on tile boundaries · 7386eda0
      Ryan Lei authored
      This commit adds a new experiment to allow disabling of loop filtering
      on tile boundaries. It is implemented by adding a syntax field
      "loopfilter_across_tiles_enabled" into the uncompressed frame header. 
      If it is set to 0, decoder and encoder will disables loop filtering for
      block edges that are also tile boundaries.

      Add options setting number of tile groups or MTU. · af6df175
      Thomas Davies authored
      Default MTU size is 0, which implies a fixed number
      of tile groups. MTU matching overrides fixed tile
      group. MTU matching will succeed unless a single
      tile is bigger than the MTU.
      
      --mtu-size is in bytes, and includes headers but
      not transport/wrapper overheads
