      aarch64: Update the var2 functions to the new signature · 98e9543b
      Martin Storsjö authored
      The existing functions could easily be used by just calling them
      twice - this would give the following cycle numbers from checkasm:
      
      var2_8x8_c:      4110
      var2_8x8_neon:   1505
      var2_8x16_c:     8019
      var2_8x16_neon:  2545
      
      However, by merging both passes into the same function, we get the
      following speedup:
      var2_8x8_neon:   1205
      var2_8x16_neon:  2327

      Add support for levels 6, 6.1, and 6.2 · 6f8aa71c
      Henrik Gramner authored
      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.

      analyse: Reduce the size the cost_mv arrays · c9d2c1c8
      Henrik Gramner authored
      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.

      Fix 8x8dct in lossless encoding · 79b36f27
      Anton Mitrofanov authored
      Change V and H intra prediction in lossless (TransformBypassModeFlag == 1)
      macroblocks to correctly adhere to the specification. Affects lossless
      encoding with 8x8dct or mix of lossless with normal macroblocks.
      
      8x8dct has already been disabled in lossless mode for some time due to
      being out-of-spec but this will allow us to re-enable it again.

      mbtree: Fix buffer overflow · 68a55021
      Anton Mitrofanov authored
      Could occur on the 1st pass in combination with --fake-interlaced and
      some input heights due to allocating a too small buffer.
