      Trap request to display non-existant frame · 709fecac
      Adrian Grange authored
      If show_existing_frame indicates that the decoder should
      display an existing (previously decoded) frame, add a
      check to make sure that the signaled buffer does contain
      a valid decoded frame.

      Removed the reset of mode_info from previous frame · 896d79a5
      Yaowu Xu authored
      Prior to this commit, both encoder and decoder reset mode/mv info from
      previous frame in error resilient mode to ensure bitstreams are able to
      decode when there is loss of frame in decoder side. However, this is
      not necessary. This commit changed to remove the reset, so encoder can
      continue to use mode/mv/partition information from previously encoded
      frame without affecting decodeablilty under loss of frame.

      Add get release decoder frame buffer functions. · e8e15279
      Frank Galligan authored
      This CL changes libvpx to call a function when a frame buffer
      is needed for decode. Libvpx will call a release callback when
      no other frames reference the frame buffer. This CL adds a
      default implementation of the frame buffer callbacks. Currently
      only VP9 is supported. A future CL will add support for
      applications to supply their own frame buffer callbacks.

      vp9 decoder: row-based multi-threaded loopfilter · 903801f1
      Yunqing Wang authored
      Implemented parallel loopfiltering, which uses existing tile-
      decoding threads. Each thread works on one row, and when that row
      is loopfiltered, it moves to next unattended row. To ensure the
      correct filtering order, threads are synchronized and one
      superblock is filtered only if the superblocks it depends on are
      filtered already.
      
      To reduce synchronization overhead and speed up the decoder, we use
      nsync > 1 for high resolution.
      
      Performance tests:
      1. on desktop:
      8-tile 4k video using 8 threads, speedup: 70% - 80%
      4-tile HD video using 4 threads, speedup: ~35%
      2. on mobile device(Nexus 7):
      4-tile 1080p video using 4 threads, speedup: 18% - 25%
      4-tile 1080p video using 2 threads, speedup: 10% - 15%
