      error check vp9 superframe parsing · c3db2d8b
      Jim Bankoski authored
      This patch insures that the last byte of a chunk that contains a
      valid superframe marker byte,  actually has a proper superframe index.
      If not it returns an error.
      
      As part of doing that the file : vp90-2-15-fuzz-flicker.webm now fails
      to decode properly and moves to the invalid file test from the test
      vector suite.

      Fix out of boundary memory read in fuzz test on vpxdec · 1ba18717
      Jingning Han authored
      This commit fixes frame header decoding for superframe index, to
      prevent out of boundary memory read triggered by fuzz test
      vector. It resolves a chromium security violation issue
      crbug.com/376802.
      
      The issue was introduced in the change:
      
      Add VPXD_SET_DECRYPTOR support to the VP9 decoder.
      cl-id I88f86c8ff9af34e0b6531028b691921b54c2fc48
      
      where the buffer was read before validation check on index offset
      applied.
      
      A test vector is added accordingly.

      The test vector has segment enabled with different quantizer used for
      different segments for bot the first frame(key) frame and the rest of

      Fix decoder resolution change with tiles · 6ae58931
      Frank Galligan authored
      There was a bug with the decoder that if you started the decoder
      with more threads than the first frame had tile columns. Afterwards
      tried to decode a frame with more tile columns than the first frame,
      the decoder would hang. E.g. run vpxdec --threads=4. The first frame
      had two tile columns, then the next key frame had 4 tile columns, the
      decoder would hang. If you started with 4 tiles and switched to 2
      tiles the decoder would be fine. The issue is that the worker the thread
      loop is using is stale.
      
      I added a test vector "vp90-2-14-resize-848x480-1280x720.webm" that
      exhibited the bug.

      [BITSTREAM]Fix the scaling calculation · 4f857bac
      Yaowu Xu authored
      For very large size video image, the scaling calculation may need use
      value beyond the range of int. This commit upgrade the value to 64bit
      to make sure the calculation do not wrap around INT_MAX.
      
      The change corrected the decoder behavior.
      
      The bug affects only very large resolution video because the scaling
      calculation was sufficient for image size smaller than 2^13.
      
      This resolves issue:

      Disable update of last_show_frame for existing frame · 64e25974
      Adrian Grange authored
      When showing a previously decoded frame, i.e. when
      show_existing_frame=1, the update of the
      last_show_frame flag must be disabled.
      
      This is to ensure that the last_show_frame flag
      reflects the state of the flag for the immediately
      previously decoded frame rather then the value that
      was forced to ensure that a previously decoded frame
      would be displayed.
      
      This patch also adds a test vector to verify that the
      display_existing_frame flag works as expected. Code
      for generating the test vector can be found in this
      patch:
      https://gerrit.chromium.org/gerrit/#/c/68581/
      
      (Bug originally reported by Alexander Voronov
      <ru.xalba@gmail.com>).

      Fix loopfilter of leftmost 4x4 edges in SB · 858475a0
      John Koleszar authored
      For cases where there's no transform set in bit 0 (the left edge of
      the SB) but bit 0 of mask_4x4_int is set (the edge 4 pixels from the
      left edge needs filtering), it was incorrectly being skipped before.
      This situation only happens on the leftmost edge of the image, as
      the edge at column 0 is intentionally skipped since there aren't
      pixels to the left to read.
