    <title>Description</title>

    <para>This is a packed grey-scale image format with a depth of 10 bits per
      pixel. Pixels are stored in a bit-packed array of 10bit bits per pixel,
      with no padding between them and with the most significant bits coming
      first from the left.</para>

    <example>
      <title><constant>V4L2_PIX_FMT_Y10BPACK</constant> 4 pixel data stream taking 5 bytes</title>

      <formalpara>
	<title>Bit-packed representation</title>
	<para>pixels cross the byte boundary and have a ratio of 5 bytes for each 4
          pixels.
