+V4L2_PIX_FMT_YUV410
+Planar formats with ¼ horizontal and vertical chroma resolution, also
+known as YUV 4:1:0
+
+
+Description
+===========
+
+These are planar formats, as opposed to a packed format. The three
+components are separated into three sub-images or planes. The Y plane is
+first. The Y plane has one byte per pixel. For ``V4L2_PIX_FMT_YVU410``,
+the Cr plane immediately follows the Y plane in memory. The Cr plane is
+¼ the width and ¼ the height of the Y plane (and of the image). Each Cr
+belongs to 16 pixels, a four-by-four square of the image. Following the
+Cr plane is the Cb plane, just like the Cr plane.
+``V4L2_PIX_FMT_YUV410`` is the same, except the Cb plane comes first,
+then the Cr plane.
+
+If the Y plane has pad bytes after each row, then the Cr and Cb planes
+have ¼ as many pad bytes after their rows. In other words, four Cx rows
+(including padding) are exactly as long as one Y row (including
+padding).
+
+**Byte Order.**
+Each cell is one byte.
