  hwcontext_vaapi: add a quirk for the missing MemoryType attribute
  
  The Intel binary iHD driver does not support the
  VASurfaceAttribMemoryType, so surface allocation will fail when using
  it.

  vaapi_h265: Fix buffering parameters
  
  A decoder may need this to be set correctly to output frames in the
  right order.

  vaapi_h265: Fix slice header writing
  
  This was not observed earlier because the only syntax element which
  it normally misses with the current setup is slice_qp_delta, but that
  is always going to be zero (in IDR frames QP isn't varied on the
  slice) which will always exp-golomb code as a single 1 bit.  The
  immediately following part is the byte alignment, which is always a 1
  bit followed by 0s which are ignored, so as long as the bitstream is
  never aligned at that point we will never notice because the only
  difference is that an ignored bit is a 1 instead of a 0.

  vaapi_encode: Decide on GOP setup before initialising sequence parameters
  
  This was always too late; several fields related to it have been incorrectly
  zero since the encoder was added.
