  Use a larger integer type for the slice_table array
  
  Makes it possible to use slicing with resolutions larger than 2^24 pixels.

• analyse : Reduce the size the cost_mv arrays

  19 février 2017, par Henrik Gramner

  analyse: Reduce the size the cost_mv arrays
  
  Use a dynamic size depending on the MV range. Reduces memory consumption by
  up to a few megabytes.
  
  Drop a related old miscompilation check since it may otherwise cause an
  out-of-bounds memory access.
  
  Also remove an unused extern variable declaration.

• Add support for levels 6, 6.1, and 6.2

  15 février 2017, par Henrik Gramner

  Add support for levels 6, 6.1, and 6.2
  
  These levels were added in the 2016-10 revision of the H.264 specification and
  improves support for content with high resolutions and/or high frame rates.
  
  Level 6.2 supports 8K resolution at 120 fps.
  
  Also shrink the x264_levels array by using smaller data types.
