      MAX_TILE: Allow list of tile widths/heights · 26ad0b22
      Dominic Symes authored
      The aomenc API is modified to allow --tile_width and --tile_height to take a list of sizes.
      For example, --tile_width=2,3 will give tiles of widths 2,3,2,3,... until the image width
      is exhausted. --tile_width=2 will still work to gives tiles of width 2.

      intra_interp - fix dr_prediction_z1 and _z3 · 80dd4b94
      Jonathan Matthews authored
      The low bd versions should have the same functionality as the
      high bd versions.  This patch removes the incorrect optimisation,
      in order to rapidly fix the functionality.

      LOOPFILTER_LEVEL: add flexibility for EXT_DELTA_Q · 880166ab
      Cheng Chen authored
      When experiment LOOPFILTER_LEVEL is on, there're four base filter levels
      for each frame. This patch enables one to use one delta or four deltas
      to update corresponding filter levels for each superblock in
      1 bit per frame is sent through bitstream to select one or four deltas.
      Now, we hard code to use one delta.

      Fix global-motion + error-resilient-mode · d7c8bd51
      David Barker authored
      Patch https://aomedia-review.googlesource.com/c/21783
      changed things so that error-resilient frames use the default
      global motion parameters as a reference, rather than taking
      the reference from the previous frame.
      This was implemented by clearing out cm->prev_frame->global_motion
      when we have an error-resilient frame. Unfortunately, this causes
      an issue: if we have an error resilient frame which isn't stored
      into any reference slots, followed by a non-error-resilient frame,
      then both frames refer to the same prev_frame. The second frame
      then delta-codes against cm->prev_frame->global_motion, but
      this was reset to the default values by the intervening
      error-resilient frame!
      In order to allow the above case to work as intended, expand the
      default warp parameter set to a full WarpedMotionParams struct,
      and use that as the reference for error-resilient frames.
      This also allows us to remove set_default_warp_params, as we
      can now just copy directly from default_warp_params.

      Deduplicate use_reference_buffer/frame_id_numbers_present_flag · 5e70a114
      David Barker authored
      These two flags serve essentially the same purpose, so we can
      simplify down to just having one flag. Since the
      frame_id_numbers_present_flag is older and listed in the
      reference-buffer design doc, this is the one we'll keep.
      Note that, previously, frame_id_numbers_present_flag was only
      sent when CONFIG_OBU was enabled - otherwise it was always set
      to 1. On the other hand, use_reference_buffer was always signalled
      so that allowed us to disable frame ids even without CONFIG_OBU.
      In order to keep the ability to disable frame IDs without
      CONFIG_OBU, we send a "real" sequence header (ie, with the same
      data as in CONFIG_OBU) in-line within the uncompressed header.
      This is sent every keyframe and every intra-only frame, just
      as the use_reference_buffer flag was before this patch.
