      Fix bug 837: realloc mode info buffers on resize · 4e30565a
      Adrian Grange authored
      The test to determine if the mode info buffers need
      to be resized when the frame size changes was
      incorrect, as per bug 837.
      
      By storing the size of the allocated data structure,
      a simple test determines whether to allocate more
      memory when the frame size changes.

      Fix reference frame size restrictions. · 899585eb
      Jim Bankoski authored
      The issue was introduced by commit g9f37d149 with adding explicit
      restrictions on reference-frame scale factors. The restriction
      is checked against aligned-by-8 frame dimensions, not against
      original ones. So, for example, frame of 35×35 actually can refer
      to frame of 70×70, but the new check won't allow this. It will
      compare 35 vs 72 (not 70), so 2x downscale limit will be exceeded.

      Changed validation of reference frame size · 9261e1aa
      Yaowu Xu authored
      A previous change, https://gerrit.chromium.org/gerrit/#/c/70632,
      introduced a size validation for reference frames to insuare the
      input stream is a valid VP9 stream. However, the logic requiring
      all reference frames have valid size turned out to be too strict.
      
      In this commit, we modify the validation to require one of the
      reference frame has valid dimension. In addition, the decoder
      reports error whenever it detects the use of reference frame
      with invalid scalig ratio.

      Fix allocation of context buffers on frame resize · 423e8a97
      Adrian Grange authored
      The patch:
      https://gerrit.chromium.org/gerrit/#/c/70814/
      changed the test that determined whether the context
      frame buffers needed to be reallocated or not.
      
      The code checked for a change in total frame area
      to signal the need to reallocate context buffers.
      However, the above_context buffer needs to be
      resized i:xf only the width of the frame has increased.

      Modified frame buffer handling · f68aaa38
      Adrian Grange authored
      This patch is the first step toward simplifying the
      frame buffer handling.
      
      The final goal is to have a common frame buffer handling
      framework for both encoder and decoder that incorporates
      the existing ability to use externally allocated memory.

      Prepare for frame parallel decoding, the reference count buffers
      need to be protected by mutex. Move vp9_thread.* to common

      Refactor decode_tiles and loopfilter code. · 20c1edf6
      hkuang authored
      The current decode_tiles decodes the frame one tile by one tile
      and then loopfilter the whole frame or use another worker thread to
      do loopfiltering.
      
      |------|------|------|------|
      |Tile1-|Tile2-|Tile3-|Tile4-|
      |------|------|------|------|
      
      For example, if a tile video has one row and four cols, decode_tiles
      will decode the Tile1, then Tile2, then Tile3, then Tile4.
      And during decode each tile, decode_tile will decode row by row in
      each tile.
      
      For frame parallel decoding, decode_tiles will decode video in row order
      across the tiles. So the order will be:
      "Decode 1st row of Tile1" -> "Decode 1st row of Tile2"
      -> "Decode 1st row of Tile3" -> "Decode 1st row of Tile4"
      -> "Decode 2nd row of Tile1" -> "Decode 2nd row of Tile2"
      -> "Decode 2nd row of Tile3" -> "Decode 2nd row of Tile4"-> "loopfilter 1st row"

      Fix check of debug counts for corrupt frame · 99892e85

        cm->frame_parallel_decoding_mode == 0, but
        new_fb->corrupted == 1.
      
      The assert in debug_check_frame_counts fails to
      take into account the case of a corrupt frame.
