      vp8: fix up handling of segmentation_maps in reference frames. · ce42a048
      Ronald S. Bultje authored
      Associate segmentation_map[] with reference frame, rather than
      decoding instance. This fixes cases where the map would be free()'ed
      on e.g. a size change in one thread, whereas the other thread was
      still accessing it. Also, it fixes cases where threads overwrite data
      that is still being referenced by the previous thread, who thinks that
      it's part of the frame previously decoded by the next thread.
