<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.
