• lavc/qsvenc : set HRD buffer size

  1er décembre 2017, par Li, Zhong

  lavc/qsvenc: set HRD buffer size
  
  Hypothetical Reference Decoding (HRD) model assumes that data flows
  into a buffer of the fixed size BufferSizeInKB with a constant bitrate.
  Smaller BufferSizeInKB means smaller frame size variations,
  but more difficult to maintain HRD.
