      Compute all token encodings from symbol trees. · 3c056790
      Nathan E. Egge authored
      The av1_token encodings must match the contents of the aom_tree_index
       structures so generate all encodings from the symbol trees.

      Update segment tree_cdf per frame. · f627e58e
      Nathan E. Egge authored
      Move computing the segmentation_probs.tree_cdf table per symbol to
       computing it only when the probabilities are updated.

      Move CLPF block signals from frame to SB level. · 97535038
      Steinar Midtskogen authored
      These signals were in the uncompressed frame header (as a temporary
      hack), which caused two problems:
      
      * We don't want that header to be duplicated in the slice header
      * It was necessary to signal the number of bits to transmit up front
      
      However, the filter size can be 128x128 which is greater than the SB
      size, and a decoder wouldn't be able to know whether to read a bit or
      not until the final SB of that 128x128 block has been decoded
      (depending on whether the 128x128 is all skip or not).  Therefore the
      signalling was changed for 128x128 blocks so that every top left SB of
      a 128x128 filter block contains a signal regardless of whether the
      block is all skip or not.  Also, all the MB's of 128x128 block are
      filtered even if they are skip MB's.  This gives the signal a purpose
      even when the 128x128 block is all skip, and it also gives a slight
      coding gain as it leaves a way to filter skip blocks, which was
      previously forbidden.
