+
+ <para>These are two-plane versions of the YUV 4:4:4 format. The three
+ components are separated into two sub-images or planes. The Y plane is
+ first, with each Y sample stored in one byte per pixel. For
+ <constant>V4L2_PIX_FMT_NV24</constant>, a combined CbCr plane
+ immediately follows the Y plane in memory. The CbCr plane has the same
+ width and height, in pixels, as the Y plane (and the image). Each line
+ contains one CbCr pair per pixel, with each Cb and Cr sample stored in
+ one byte. <constant>V4L2_PIX_FMT_NV42</constant> is the same except that
+ the Cb and Cr samples are swapped, the CrCb plane starts with a Cr
+ sample.</para>
+
+ <para>If the Y plane has pad bytes after each row, then the CbCr plane
+ has twice as many pad bytes after its rows.</para>

+
+<para>Video hardware can have various cropping, composing and scaling
+limitations. It may only scale up or down, support only discrete scaling
+factors, or have different scaling abilities in the horizontal and vertical
+directions. Also it may not support scaling at all. At the same time the
+cropping/composing rectangles may have to be aligned, and both the source and
+the sink may have arbitrary upper and lower size limits. Therefore, as usual,
+drivers are expected to adjust the requested parameters and return the actual
+values selected. An application can control the rounding behaviour using <link

+ <title>Configuration of video capture</title>
+
+<para>See figure <xref linkend="sel-targets-capture" /> for examples of the
+selection targets available for a video capture device. It is recommended to
+configure the cropping targets before to the composing targets.</para>
+
+<para>The range of coordinates of the top left corner, width and height of
+areas that can be sampled is given by the <constant> V4L2_SEL_TGT_CROP_BOUNDS
+</constant> target. It is recommended for the driver developers to put the

+coordinates are expressed in pixels.</para>
+
+<para>The top left corner, width and height of the source rectangle, that is
+the area actually sampled, is given by the <constant> V4L2_SEL_TGT_CROP_ACTIVE
+</constant> target. It uses the same coordinate system as <constant>
+V4L2_SEL_TGT_CROP_BOUNDS </constant>. The active cropping area must lie
+completely inside the capture boundaries. The driver may further adjust the
+requested size and/or position according to hardware limitations.</para>
+
+<para>Each capture device has a default source rectangle, given by the
+<constant> V4L2_SEL_TGT_CROP_DEFAULT </constant> target. This rectangle shall
+over what the driver writer considers the complete picture. Drivers shall set
+the active crop rectangle to the default when the driver is first loaded, but
+not later.</para>
+
+<para>The composing targets refer to a memory buffer. The limits of composing
+coordinates are obtained using <constant> V4L2_SEL_TGT_COMPOSE_BOUNDS
+</constant>. All coordinates are expressed in pixels. The rectangle's top/left

+
+<para>The part of a buffer into which the image is inserted by the hardware is

+rectangle. The driver must adjust the composing rectangle to fit to the

+ <title>Scaling control.</title>
+
+<para>An application can detect if scaling is performed by comparing the width
+and the height of rectangles obtained using <constant> V4L2_SEL_TGT_CROP_ACTIVE
+</constant> and <constant> V4L2_SEL_TGT_COMPOSE_ACTIVE </constant> targets. If
+these are not equal then the scaling is applied. The application can compute

+
+ <title>Comparison with old cropping API.</title>
+
+<para>The selection API was introduced to cope with deficiencies of previous
+<link linkend="crop"> API </link>, that was designed to control simple capture
+devices. Later the cropping API was adopted by video output drivers. The ioctls
+are used to select a part of the display were the video signal is inserted. It
+should be considered as an API abuse because the described operation is
+actually the composing. The selection API makes a clear distinction between
+composing and cropping operations by setting the appropriate targets. The V4L2
+API lacks any support for composing to and cropping from an image inside a
+memory buffer. The application could configure a capture device to fill only a
+part of an image by abusing V4L2 API. Cropping a smaller image from a larger
+one is achieved by setting the field <structfield>
+&v4l2-pix-format;::bytesperline </structfield>. Introducing an image offsets
+could be done by modifying field <structfield> &v4l2-buffer;::m:userptr
+</structfield> before calling <constant> VIDIOC_QBUF </constant>. Those
+operations should be avoided because they are not portable (endianness), and do
+not work for macroblock and Bayer formats and mmap buffers. The selection API
+deals with configuration of buffer cropping/composing in a clear, intuitive and
+portable way. Next, with the selection API the concepts of the padded target
+and constraints flags are introduced. Finally, <structname> &v4l2-crop;
+</structname> and <structname> &v4l2-cropcap; </structname> have no reserved
+fields. Therefore there is no way to extend their functionality. The new
+<structname> &v4l2-selection; </structname> provides a lot of place for future
+extensions. Driver developers are encouraged to implement only selection API.
+The former cropping API would be simulated using the new one. </para>
