      Fix the initial references to frame buffers. · 9ed616a5
      Frank Galligan authored
      The old code would start in a mixed state, where all the reference
      frames were pointing to frame buffer 0, but the reference counts
      were 0. This is why we needed special code for the first frame.

      Moving eob array to the encoder. · f00d157c
      Dmitry Kovalev authored
      In the decoder we don't need to save eobs, we can pass eob as an argument.
      That's why removing eob arrays from VP9Decompressor and TileWorkerData,
      and moving eob pointer from macroblockd_plane to macroblock_plane.

      Using local variable for token_cache. · 5ab920d2
      Dmitry Kovalev authored
      The difference with the old code is that originally the whole token_cache
      was initialized with zeros at the beginning of decode_coefs() function.
      Now we set several zero values explicitly with "token_cache[scan[c]] = 0".

      Use separate inter predictors for enc/dec · ba8b5e8d
      Jingning Han authored
      The decoder will construct inter predictor using lazy border extension,
      while the encoder, going with multiple runs of motion search in the rate-
      distortion optimization loop for each block, does border extension at
      frame level. This commit makes separate the inter predictors for encoder
      and decoder, respectively.

      Decouple macroblockd_plane buffer usage · d8b4c792
      Jingning Han authored
      Make the macroblockd_plane contain dynamic buffer pointers instead
      static pointers to the memory space allocated therein. The decoder
      uses the buffer allocated in pbi, while encoder will use a dual
      buffer approach for rate-distortion optimization search.

      Replacing (raster_block >> tx_size) with (block >> (tx_size << 1)). · d28f30ef
      Dmitry Kovalev authored
      The new expression is much more logical than previous one. Surprisingly
      both expressions give exactly the same set of dependent values
      -- have_top, have_left, have_right -- in vp9_predict_intra_block.

      Unifying tile decoding for both direct and inverse tile order. · 672ba3dd
      Dmitry Kovalev authored
      Now tile decoding consists of two stages:
      1. Find tile buffer start and its size, put this info into tile_buffers.
      2. Decode each tile based on information from tile_buffers.
      It seems that stage 1 can also be reused by multithreaded tile decoder.

      Using pd->dqcoeff instead of pd->qcoeff in the decoder. · a1dc97be
      Dmitry Kovalev authored
      It is more logical to use dqcoeff buffer to put there *dequantized*
      transform coefficients (inside inverse_transform_block and
      decode_coefs functions). Dequantization happens inside WRITE_COEF_CONTINUE
      qcoeff buffer should be only used in the encoder for *quantized*
      transform coefficients.

      Splitting partition_probs array into two arrays. · dde8069e
      Dmitry Kovalev authored
      We only update partition_probs for inter frames but they are constant
      for key frames. It is not necessary to have constants inside frame
      context and copy them every time. This change reduces FRAME_CONTEXT size
      by at least 48 bytes.

      Two optimizations: · a272530b
      Yaowu Xu authored
      1. Reduced the size memset based on eob for 32x32 transform. The reset
      of non-zero coefficient should probably go into where they are read in
      inverse transform functions. (TODO)
      2. Removed a redundant level of indirection.
      vp9_iht4x4_add() checks transform type and call vp9_iht4x4_16_add()
      for tranforms other than DCT_DCT. In this case, the DCT_DCT case
      has been already handled here.

      Reducing the number of foreach_transformed_block() calls. · 47b6030d
      Dmitry Kovalev authored
      The change doesn't affect the bitstream. It changes the order or function
      calls and affects how we reconstruct intra- and inter-blocks. Speed up is
      about 1...1.5%.
      For intra-blocks:
          for each transform block read tokens
          for each transform block do prediction
          for each transform block do inverse transform
          for each transform block
            read tokens
            do prediction
            do inverse transform
      For inter-blocks:
          for each transform block read tokens
          for each transform block do inverse transform
          for each transform block
            read tokens
            do inverse transform
