      Make adapt-scan support multi-thread encoding · 5d0b310b
      Jingning Han authored
      This commit makes the adaptive scan order system support multi-
      thread encoding. It fixes unit test failure issue associated with
      AV1/AVxEncoderThreadTest.EncoderResultTest/0.

      Rectangular transforms 4x8 & 8x4 · e5848dea
      Debargha Mukherjee authored
      Added a new expt rect-tx to be used in conjunction with ext-tx.
      [rect-tx is a temporary config flag and will eventually be
      merged into ext-tx once it works correctly with all other
      experiments].
      
      Added 4x8 and 8x4 tranforms for use initially with rectangular
      sub8x8 y blocks as part of this experiment.
      
      There is about a -0.2% BDRATE improvement on lowres, others pending.
      
      When var-tx is on rectangular transforms are currently not used.
      That will be enabled in a subsequent patch.

      Re-worked header files · b962646f
      Scott LaVarnway authored
      Various header/test files had to be re-worked in order to
      build "Remove cm parameter from vp9_decode_block_tokens()".
      
      This patch reverts the "Remove cm" part and only contains
      the re-worked header files.
