+Interactions between formats, controls and buffers
+==================================================
+
+V4L2 exposes parameters that influence the buffer size, or the way data is
+laid out in the buffer. Those parameters are exposed through both formats and
+controls. One example of such a control is the ``V4L2_CID_ROTATE`` control
+that modifies the direction in which pixels are stored in the buffer, as well
+as the buffer size when the selected format includes padding at the end of
+lines.
+
+The set of information needed to interpret the content of a buffer (e.g. the
+pixel format, the line stride, the tiling orientation or the rotation) is
+collectively referred to in the rest of this section as the buffer layout.
+
+Controls that can modify the buffer layout shall set the
+``V4L2_CTRL_FLAG_MODIFY_LAYOUT`` flag.
+
+Modifying formats or controls that influence the buffer size or layout require
+the stream to be stopped. Any attempt at such a modification while the stream
+is active shall cause the ioctl setting the format or the control to return
+the ``EBUSY`` error code. In that case drivers shall also set the
+``V4L2_CTRL_FLAG_GRABBED`` flag when calling
+:c:func:`VIDIOC_QUERYCTRL` or :c:func:`VIDIOC_QUERY_EXT_CTRL` for such a
+control while the stream is active.
+
+.. note::
+
+   The :c:func:`VIDIOC_S_SELECTION` ioctl can, depending on the hardware (for
+   instance if the device doesn't include a scaler), modify the format in
+   addition to the selection rectangle. Similarly, the
+   :c:func:`VIDIOC_S_INPUT`, :c:func:`VIDIOC_S_OUTPUT`, :c:func:`VIDIOC_S_STD`
+   and :c:func:`VIDIOC_S_DV_TIMINGS` ioctls can also modify the format and
+   selection rectangles. When those ioctls result in a buffer size or layout
+   change, drivers shall handle that condition as they would handle it in the
+   :c:func:`VIDIOC_S_FMT` ioctl in all cases described in this section.
+
+Controls that only influence the buffer layout can be modified at any time
+when the stream is stopped. As they don't influence the buffer size, no
+special handling is needed to synchronize those controls with buffer
+allocation and the ``V4L2_CTRL_FLAG_GRABBED`` flag is cleared once the
+stream is stopped.
+
+Formats and controls that influence the buffer size interact with buffer
+allocation. The simplest way to handle this is for drivers to always require
+buffers to be reallocated in order to change those formats or controls. In
+that case, to perform such changes, userspace applications shall first stop
+the video stream with the :c:func:`VIDIOC_STREAMOFF` ioctl if it is running
+and free all buffers with the :c:func:`VIDIOC_REQBUFS` ioctl if they are
+allocated. After freeing all buffers the ``V4L2_CTRL_FLAG_GRABBED`` flag
+for controls is cleared. The format or controls can then be modified, and
+buffers shall then be reallocated and the stream restarted. A typical ioctl
+sequence is
+
+ #. VIDIOC_STREAMOFF
+ #. VIDIOC_REQBUFS(0)
+ #. VIDIOC_S_EXT_CTRLS
+ #. VIDIOC_S_FMT
+ #. VIDIOC_REQBUFS(n)
+ #. VIDIOC_QBUF
+ #. VIDIOC_STREAMON
+
+The second :c:func:`VIDIOC_REQBUFS` call will take the new format and control
+value into account to compute the buffer size to allocate. Applications can
+also retrieve the size by calling the :c:func:`VIDIOC_G_FMT` ioctl if needed.
+
+.. note::
+
+   The API doesn't mandate the above order for control (3.) and format (4.)
+   changes. Format and controls can be set in a different order, or even
+   interleaved, depending on the device and use case. For instance some
+   controls might behave differently for different pixel formats, in which
+   case the format might need to be set first.
+
+When reallocation is required, any attempt to modify format or controls that
+influences the buffer size while buffers are allocated shall cause the format
+or control set ioctl to return the ``EBUSY`` error. Any attempt to queue a
+buffer too small for the current format or controls shall cause the
+:c:func:`VIDIOC_QBUF` ioctl to return a ``EINVAL`` error.
+
+Buffer reallocation is an expensive operation. To avoid that cost, drivers can
+(and are encouraged to) allow format or controls that influence the buffer
+size to be changed with buffers allocated. In that case, a typical ioctl
+sequence to modify format and controls is
+
+ #. VIDIOC_STREAMOFF
+ #. VIDIOC_S_EXT_CTRLS
+ #. VIDIOC_S_FMT
+ #. VIDIOC_QBUF
+ #. VIDIOC_STREAMON
+
+For this sequence to operate correctly, queued buffers need to be large enough
+for the new format or controls. Drivers shall return a ``ENOSPC`` error in
+response to format change (:c:func:`VIDIOC_S_FMT`) or control changes
+(:c:func:`VIDIOC_S_CTRL` or :c:func:`VIDIOC_S_EXT_CTRLS`) if buffers too small
+for the new format are currently queued. As a simplification, drivers are
+allowed to return a ``EBUSY`` error from these ioctls if any buffer is
+currently queued, without checking the queued buffers sizes.
+
+Additionally, drivers shall return a ``EINVAL`` error from the
+:c:func:`VIDIOC_QBUF` ioctl if the buffer being queued is too small for the
+current format or controls. Together, these requirements ensure that queued
+buffers will always be large enough for the configured format and controls.
+
+Userspace applications can query the buffer size required for a given format
+and controls by first setting the desired control values and then trying the
+desired format. The :c:func:`VIDIOC_TRY_FMT` ioctl will return the required
+buffer size.
+
+ #. VIDIOC_S_EXT_CTRLS(x)
+ #. VIDIOC_TRY_FMT()
+ #. VIDIOC_S_EXT_CTRLS(y)
+ #. VIDIOC_TRY_FMT()
+
+The :c:func:`VIDIOC_CREATE_BUFS` ioctl can then be used to allocate buffers
+based on the queried sizes (for instance by allocating a set of buffers large
+enough for all the desired formats and controls, or by allocating separate set
+of appropriately sized buffers for each use case).

+******************
+Metadata Interface
+******************
+
+Metadata refers to any non-image data that supplements video frames with
+additional information. This may include statistics computed over the image
+or frame capture parameters supplied by the image source. This interface is
+intended for transfer of metadata to userspace and control of that operation.
+
+The metadata interface is implemented on video capture device nodes. The device
+can be dedicated to metadata or can implement both video and metadata capture
+as specified in its reported capabilities.
+
+Querying Capabilities
+=====================
+
+Device nodes supporting the metadata interface set the ``V4L2_CAP_META_CAPTURE``
+flag in the ``device_caps`` field of the
+:c:type:`v4l2_capability` structure returned by the :c:func:`VIDIOC_QUERYCAP`
+ioctl. That flag means the device can capture metadata to memory.
+
+At least one of the read/write or streaming I/O methods must be supported.
+
+
+Data Format Negotiation
+=======================
+
+The metadata device uses the :ref:`format` ioctls to select the capture format.
+The metadata buffer content format is bound to that selected format. In addition
+to the basic :ref:`format` ioctls, the :c:func:`VIDIOC_ENUM_FMT` ioctl must be
+supported as well.
+
+To use the :ref:`format` ioctls applications set the ``type`` field of the
+:c:type:`v4l2_format` structure to ``V4L2_BUF_TYPE_META_CAPTURE`` and use the
+:c:type:`v4l2_meta_format` ``meta`` member of the ``fmt`` union as needed per
+the desired operation. Both drivers and applications must set the remainder of
+the :c:type:`v4l2_format` structure to 0.

+Description
+===========
+
+This format describes histogram data generated by the Renesas R-Car VSP1 1-D
+Histogram (HGO) engine.
+
+The VSP1 HGO is a histogram computation engine that can operate on RGB, YCrCb
+or HSV data. It operates on a possibly cropped and subsampled input image and
+computes the minimum, maximum and sum of all pixels as well as per-channel
+histograms.
+
+The HGO can compute histograms independently per channel, on the maximum of the
+three channels (RGB data only) or on the Y channel only (YCbCr only). It can
+additionally output the histogram with 64 or 256 bins, resulting in four
+possible modes of operation.
+
+- In *64 bins normal mode*, the HGO operates on the three channels independently
+  to compute three 64-bins histograms. RGB, YCbCr and HSV image formats are
+  supported.
+- In *64 bins maximum mode*, the HGO operates on the maximum of the (R, G, B)
+  channels to compute a single 64-bins histogram. Only the RGB image format is
+  supported.
+- In *256 bins normal mode*, the HGO operates on the Y channel to compute a
+  single 256-bins histogram. Only the YCbCr image format is supported.
+- In *256 bins maximum mode*, the HGO operates on the maximum of the (R, G, B)
+  channels to compute a single 256-bins histogram. Only the RGB image format is
+  supported.

+
+
+Description
+===========
+
+This format describes histogram data generated by the Renesas R-Car VSP1
+2-D Histogram (HGT) engine.
+
+The VSP1 HGT is a histogram computation engine that operates on HSV
+data. It operates on a possibly cropped and subsampled input image and
+computes the sum, maximum and minimum of the S component as well as a
+weighted frequency histogram based on the H and S components.
+
+The histogram is a matrix of 6 Hue and 32 Saturation buckets, 192 in
+total. Each HSV value is added to one or more buckets with a weight
+between 1 and 16 depending on the Hue areas configuration. Finding the
+corresponding buckets is done by inspecting the H and S value independently.
+
+The Saturation position **n** (0 - 31) of the bucket in the matrix is
+found by the expression:
+
+    n = S / 8
+
+The Hue position **m** (0 - 5) of the bucket in the matrix depends on
+how the HGT Hue areas are configured. There are 6 user configurable Hue
+Areas which can be configured to cover overlapping Hue values:
+
+::
+
+         Area 0       Area 1       Area 2       Area 3       Area 4       Area 5

+        <0..............................Hue Value............................255>
+
+When two consecutive areas don't overlap (n+1L is equal to nU) the boundary
+value is considered as part of the lower area.
+
+Pixels with a hue value included in the centre of an area (between nL and nU
+included) are attributed to that single area and given a weight of 16. Pixels
+with a hue value included in the overlapping region between two areas (between
+n+1L and nU excluded) are attributed to both areas and given a weight for each
+of these areas proportional to their position along the diagonal lines
+(rounded down).
+
+The Hue area setup must match one of the following constrains:
+
+::
+
+    0L <= 0U <= 1L <= 1U <= 2L <= 2U <= 3L <= 3U <= 4L <= 4U <= 5L <= 5U

+      - Changing this control value may modify the layout of the
+        buffer (for video devices) or the media bus format (for sub-devices).
+
+	A typical example would be the ``V4L2_CID_ROTATE`` control.
+
+	Note that typically controls with this flag will also set the
+	``V4L2_CTRL_FLAG_GRABBED`` flag when buffers are allocated or
+	streaming is in progress since most drivers do not support changing
+	the format in that case.
