• VfW: BRA[64],b64a,BGR[48],P010,P016,P210,P216,Y3[10][10],Y3[10][16],v210
  experimental, just to have feedback
  
  Default format FourCCs:
  RGB64: BRA[64]
  RGB48: BGR[48]
  YUV420P10: P010
  YUV420P16: P016
  YUV422P10: P210
  YUV422P16: P216
  
  Use these global variables to override default formats:
  OPT_Enable_V210 = true --> v210 for YUV422P10
  OPT_Enable_Y3_10_10 = true --> Y3[10][10] for YUV422P10
  OPT_Enable_Y3_10_16 = true --> Y3[10][16] for YUV422P16
  OPT_Enable_b64a = true --> b64a for RGB64
• Overlay: blend for float format
