• hevc : Add support for alternative transfer characterics SEI

  hevc: Add support for alternative transfer characterics SEI
  
  The use of this SEI is for backward compatibility in HLG HDR systems:
  older devices that cannot interpret the "arib-std-b67" transfer will
  get the compatible transfer (usually bt709 or bt2020) from the VUI,
  while newer devices that can interpret HDR will read the SEI and use
  its value instead.

• d3d11va : Link directly to dxgi.dll and d3d11.dll functions if LoadLibrary is unavailable

  d3d11va: Link directly to dxgi.dll and d3d11.dll functions if LoadLibrary is unavailable
  
  When targeting the UWP API subset, the LoadLibrary function is not
  available (and the fallback, LoadPackagedLibrary, can't be used to
  load system DLLs). In these cases, link directly to the functions
  in the DLLs instead of trying to load them dynamically at runtime.

• nvenc : Add default value for AVCodecContext::refs

  8 juin 2017, par Srinath K R

  nvenc: Add default value for AVCodecContext::refs
  
  AVCodecContext::refs is used to control the DPB size to be used by the
  encoder. The default value for AVCodecContext::refs as set in
  libavcodec/options_table.h is 1.
  
  This patch sets AVCodecContext::refs to 0 for h264_nvenc and hevc_nvenc in
  order to let the driver take the decision of the correct DPB size to use in
  all cases.

• dxva : add support for new dxva2 and d3d11 hwaccel APIs

  7 juin 2017, par wm4

  dxva: add support for new dxva2 and d3d11 hwaccel APIs
  
  This also adds support to avconv (which is trivial due to the new
  hwaccel API being generic enough).
  
  The new decoder setup code in dxva2.c is significantly based on work by
  Steve Lhomme <robux4@gmail.com>, but with heavy changes/rewrites.
