      Revert "Remove mi_grid_* structures." · 8b17f7f4

      For the test clip used, the decoder performance improved by ~2%.
      This is also an intermediate step towards adding back the
      mode_info streams.

      using this to control reallocation would miss a change if the function

      vp9_ethread: add parallel loopfilter · e76eaf05
      Yunqing Wang authored
      1. Added row-based loopfilter in encoder;
      2. Moved common multi-threaded loopfilter functions from decoder
         to common;
      3. Merged multi-threaded loopfilter code, and made encoder/
         decoder call same function to reduce code duplication.
      
      Encoder tests showed that 1% - 2% speedup was seen for good-quality
      2-pass mode(at speed 3); 1% - 3% speedup using 2 threads and 4% - 6%
      speedup using 4 threads were seen for real-time mode(at speed 7).

      Implement frame parallel decode for VP9. · 9ce3a7d7
      Hangyu Kuang authored
      Using 4 threads, frame parallel decode is ~3x faster than single thread
      decode and around 30% faster than tile parallel decode for frame parallel
      encoded video on both Android and desktop with 4 threads. Decode speed is
      scalable to threads too which means decode could be even faster with more threads.

      Remove mi_grid_* structures. · c70cea97
      hkuang authored
      mi_grid_* are arrays of pointer to pointer. They save the pointers that point
      to the MIs in cm->mi. But they are unnecessary and complicated. The original
      goal was to remove MODE_INFO_t copy. But with an extra MODE_INFO_t pointer
      inside MODE_INFO_t, same goal could be achieved.
      
      This commit totally removes the mi_grid_* structures. But there are still
      many dummy MODE_INFO_t inside cm->mi which are a waste of memory. Next commit
      will do on-demand MODE_INFO_t allocation in order to save these memories.

      update vp9_thread.[hc] · e656f44c
      James Zern authored
      pull the latest from WebP, which adds a worker interface abstraction
      allowing an application to override init/reset/sync/launch/execute/end
      
      this has the side effect of removing a harmless, but annoying, TSan
      warning.

      We only used two members from that struct: max_threads and inv_tile_order.
      Moving them directly to VP9Decoder struct.

      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.
