      Fix mismatch with ext-interp. · 1502d9e4
      Geza Lore authored
      The encoder signals the interp filter type in the frame header if all
      blocks use the same filter (see bitstream.c:fix_interp_filter). This
      decision is made based on the counts, but with ext-interp, the counts
      are actually only incremented for blocks that fail vp10_is_interp_needed
      (see for example encodeframe.c:update_state), otherwise a default value
      is used (EIGHTTAP_REGULAR). The decoder however first checks if the
      interp filter is signaled at the frame level, and uses that filter type
      for all blocks, even if the default value should have been used.
      
      This patch makes the decoder first check with vp10_is_interp_needed
      to see if the default value should be used and then checks the frame
      level signaling, which reconciles the difference between encoder and
      decoder.

      General code cleanup, but also use the same supertx condition for
      ext-partition-types as for conventional partitions.

      Change to use proper type in vp10_token_state · 0d7dc0ca
      Yaowu Xu authored
      "qc" in vp10_token_state is used to save quantized coefficients, this
      commit changes the type from short to tran_low_t to properly reflect
      the value range for highbitdepth build.
      
      This fixes an out-of-range bug when optimize_b is used in highbitdepth
      build.

      Add 1D tx set that corresponds to reduced ext tx inter sets · 3da61efe
      Sarah Parker authored
      This is the set of 1D transforms that are used in each
      ext_tx_used_inter set. The 1D sets will help speed up
      the ext tx pruning functions.

      Removes integer divides from backward updates for VP10.
      Currently this is put in as part of the entropy experiment.
      Coding efficiency change is in the noise level.

      Fix some mismatches when using ext-interp. · bf93b385
      Geza Lore authored
      With ext interp, write_switchable_interp_filter calls
      vp10_is_interp_needed, which needs access to the reference frame
      buffers to check if they are scaled, the ref frame buffer pointer
      at this point used to be uninitialized in the encoder resulting in
      bitstream syntax mismatch when the encoder/decoder did not read/write
      the interp filter element consistently.
