      2-pass VBV support and improved VBV handling · 56f2bc89
      Gabriel Bouvigne authored
      Dramatically improves 1-pass VBV ratecontrol (especially CBR) and provides support for VBV in 2-pass mode.  This consists of a series of functions that attempts to find overflows and underflows in the VBV from the first-pass statsfile and fix them before encoding.
      1-pass VBV code partially by Fiona Glaser.

      Fix noise reduction in threaded mode. · 344cb169
      Alexander Strange authored
      Previously enabling noise reduction with threads had no effect.
      Note that this is not an optimal solution; each thread still tracks noise reducation separately (unlike in single-threaded mode).

      2x faster quant. 2% overall. · 10265a0c
      Loren Merritt authored
      side effects:
      not bit-identical to the previous algorithm.
      while the new algorithm covers a wider range of cqms than the previous one did,
      I couldn't find a good way to fallback to a general version for the extreme
      cqms. so now it refuses to encode extreme cqms instead of just being slower.
      lays a framework for custom deadzone matrices, though I didn't add an api.
