Hey, I'm really struggling with this one. I'am trying to port a small piece of someone else's code to Python and this is what I have:

typedef struct
{
  uint8_t Y[LUMA_HEIGHT][LUMA_WIDTH];
  uint8_t Cb[CHROMA_HEIGHT][CHROMA_WIDTH];
  uint8_t Cr[CHROMA_HEIGHT][CHROMA_WIDTH];
} __attribute__((__packed__)) frame_t;

frame_t frame;

 while (! feof(stdin))
  {
    fread(&frame, 1, sizeof(frame), stdin);

    // DO SOME STUFF
  }

Later I need to access the data like so: frame.Y[x][y]

So I made a Class 'frame' in Python and inserted the corresponding variables(frame.Y, frame.Cb, frame.Cr). I have tried to sequentially map the data from Y[0][0] to Cr[MAX][MAX], even printed out the C struct in action but didn't manage to wrap my head around the method used to put the data in there. I've been struggling overnight with this and have to get back to the army tonight, so any immediate help is very welcome and appreciated.

Thanks
