      Modify the frame context memory deallocation · 12284334
      Yunqing Wang authored
      This patch was to fix the vpxdec fuzzing3 test failure. When an
      error occurs, setjmp() is invoked, which calls the decoder
      removing routine. In multiple thread situation, other threads
      could try to access the frame context memory that is already
      deallocated, thus causing a segfault.
      
      An invalid unit test was added for this issue.

      Totally remove prev_mi in VP9 decoder. · 4cc7c5a1
      hkuang authored
      This will save the memory and improve the decode speed due to
      removing unnecessary memset of big prev_mi array for
      all the key frames.
      
      Decoding a all key frames 1080p video shows speed improve around 2%.

      WORKAROUND FIX FOR GCC4.9.1 · 86175a57
      levytamar82 authored
      In the function mb_lpf_horizontal_edge_w_avx2_16 the usage of the intrinsic
      _mm256_cvtepu8_epi16 cause a compiler bug in gcc 4.9.1.
      until it will be fixed I created a workaround that create the up convert by
      using broadcast128+shuffle.
      The bug was reported here:

      Yaowu Xu authored
      A recent change has introduced big quality drops for speed 7 and 12
      for --rt mode. The change reverted the big drop and improved quality
      by 9.5% for speed 7 and 13.4% for speed 12.

      Bind motion vectors with frame buffer structure. · 55577431
      hkuang authored
      This will save a lot of memory for decoder due to removing of prev_mi,
      but prev_mi is still needed in encoder. So this will increase a little bit
      memory for encoder.
