  hwcontext_dxva2 : add support for the P8 format
  This format is used internally by the QSV encoder to store the encoded
  
  bitstream.

  hwcontext_qsv : add support for the P8 format
  When using GPU surfaces with QSV, one needs to supply a frame allocator,
  
  which will be invoked to pass surface pools to libmfx.
  
  For encoding, this allocator gets invoked not only for the pool of input
  
  frames, but also for a separate pool of (apparently) reconstructed frames
  
  and another pool of MFX_FOURCC_P8, which on Windows needs to return
  
  D3DFMT_P8 D3D surfaces. Those are probably used to store the encoded
  
  bitstream on the GPU.

  hwcontext_qsv : do not fail when download/upload VPP session creation fails
  Certain pixel formats (e.g. P8) might not be supported for
  
  download/upload through VPP operations, but can still be used otherwise.
