The Y plane has one byte per pixel. For 5<code class="constant">V4L2_PIX_FMT_YVU410</code>, the Cr plane immediately 6follows the Y plane in memory. The Cr plane is ¼ the width and 7¼ the height of the Y plane (and of the image). Each Cr belongs 8to 16 pixels, a four-by-four square of the image. Following the Cr 9plane is the Cb plane, just like the Cr plane. 10<code class="constant">V4L2_PIX_FMT_YUV410</code> is the same, except the Cb 11plane comes first, then the Cr plane.</p><p>If the Y plane has pad bytes after each row, then the Cr 12and Cb planes have ¼ as many pad bytes after their rows. In 13other words, four Cx rows (including padding) are exactly as long as 14one Y row (including padding).</p><div class="example"><a name="idp1102277404"></a><p class="title"><b>Example 2.24. <code
