+V4L2_PIX_FMT_NV15 ('NV15')
+**************************
+
+Format with ½ horizontal and vertical chroma resolution, also known as
+YUV 4:2:0. One luminance and one chrominance plane with alternating
+chroma samples similar to ``V4L2_PIX_FMT_NV12`` but with 10-bit samples
+that are grouped into four and packed into five bytes.
+
+The '15' suffix refers to the optimum effective bits per pixel which is
+achieved when the total number of luminance samples is a multiple of 8.
+
+
+Description
+===========
+
+This is a packed 10-bit two-plane version of the YUV 4:2:0 format. The
+three components are separated into two sub-images or planes. The Y plane
+is first. The Y plane has five bytes per each group of four pixels. A
+combined CbCr plane immediately follows the Y plane in memory. The CbCr
+plane is the same width, in bytes, as the Y plane (and of the image), but
+is half as tall in pixels. Each CbCr pair belongs to four pixels. For
+example, Cb\ :sub:`00`/Cr\ :sub:`00` belongs to Y'\ :sub:`00`,
+Y'\ :sub:`01`, Y'\ :sub:`10`, Y'\ :sub:`11`.
+
+If the Y plane has pad bytes after each row, then the CbCr plane has as
+many pad bytes after its rows.
+
+**Byte Order.**
+Little endian. Each cell is one byte. Pixels cross the byte boundary.
