  reduce the vertical alignment constraint when possible to reduce
  
  memory usage.

• avdevice/decklink : fix MSVC build issues

  6 mai 2017, par Aaron Levinson

  avdevice/decklink : fix MSVC build issues
  Purpose : Made minor changes to get the decklink avdevice code to build
  
  using Visual C++.
  Notes : Made changes to configure per Hendrik Leppkes's review of first
  
  and second versions of patch.  Also made slight alterations per Marton
  
  Balint's reviews.
  Comments :
  — configure : Added if enabled decklink section and setting
  
     decklink_indev_extralibs and decklink_outdev_extralibs here for
  
     both mingw and Windows.  Also eliminated the setting of these
  
     variables in the mingw section earlier in the file.
  — libavdevice/decklink_common.cpp : Switched the order of the include
  
     of libavformat/internal.h to workaround build issues with Visual
  
     C++.  See comment in file for more details.
  — libavdevice/decklink_dec.cpp :
  
  a) Rearranged the include of libavformat/internal.h (for reasons as
  
     described above).
  
  b) Made slight alteration to an argument for call to av_rescale_q() to
  
     workaround a compiler error with Visual C++.  This appears to only
  
     be an issue when building C++ files with Visual C++.  See comment
  
     in code for more details.
  — libavdevice/decklink_enc.cpp : Rearranged the include of
  
     libavformat/internal.h (for reasons as described above).
