Each pixel is stored in a 24-bit word in the little-endian order. On a little-endian machine these pixels can be deinterlaced using .. code-block:: c __u8 *buf; left0 = 0xfff & *(__u16 *)buf; right0 = *(__u16 *)(buf + 1) >> 4; **Bit-packed representation.** pixels cross the byte boundary and have a ratio of 3 bytes for each interleaved pixel. .. flat-table:: :header-rows: 0 :stub-columns: 0 - .. row 1 - Y'\ :sub:`0left[7:0]` - Y'\ :sub:`0right[3:0]`\ Y'\ :sub:`0left[11:8]` - Y'\ :sub:`0right[11:4]`
