+
+      <para>Acceptable formats on pads can (and usually do) depend on a number

+      even controls. Finding a combination of formats on all pads in a video

+      enumeration only. A format negotiation mechanism is required.</para>
+
+      <para>Central to the format negotiation mechanism are the get/set format
+      operations. When called with the <structfield>which</structfield> argument
+      set to <constant>V4L2_SUBDEV_FORMAT_TRY</constant>, the
+      &VIDIOC-SUBDEV-G-FMT; and &VIDIOC-SUBDEV-S-FMT; ioctls operate on a set of
+      formats parameters that are not connected to the hardware configuration.
+      Modifying those 'try' formats leaves the device state untouched (this
+      applies to both the software state stored in the driver and the hardware
+      state stored in the device itself).</para>
+
+      <para>While not kept as part of the device state, try formats are stored
+      in the sub-device file handles. A &VIDIOC-SUBDEV-G-FMT; call will return
+      the last try format set <emphasis>on the same sub-device file
+      handle</emphasis>. Several applications querying the same sub-device at
+      the same time will thus not interact with each other.</para>
+
+      <para>To find out whether a particular format is supported by the device,
+      applications use the &VIDIOC-SUBDEV-S-FMT; ioctl. Drivers verify and, if
+      needed, change the requested <structfield>format</structfield> based on
+      device requirements and return the possibly modified value. Applications
+      can then choose to try a different format or accept the returned value and
+      continue.</para>
+
+      <para>Formats returned by the driver during a negotiation iteration are
+      guaranteed to be supported by the device. In particular, drivers guarantee
+      that a returned format will not be further changed if passed to an
+      &VIDIOC-SUBDEV-S-FMT; call as-is (as long as external parameters, such as
+      formats on other pads or links' configuration are not changed).</para>
+
+      <para>Drivers automatically propagate formats inside sub-devices. When a
+      try or active format is set on a pad, corresponding formats on other pads
+      of the same sub-device can be modified by the driver. Drivers are free to
+      modify formats as required by the device. However, they should comply with
+      the following rules when possible:
+      <itemizedlist>
+        <listitem><para>Formats should be propagated from sink pads to source pads.

+
+      <para>Formats are not propagated across links, as that would involve

+
+      <para>Many sub-devices support cropping frames on their input or output
+      pads (or possible even on both). Cropping is used to select the area of

+      also be used as part of digital zoom implementations to select the area of
+      the image that will be scaled up.</para>
+
+      <para>Crop settings are defined by a crop rectangle and represented in a

+      size. Both the coordinates and sizes are expressed in pixels.</para>
+
+      <para>The crop rectangle is retrieved and set using the
+      &VIDIOC-SUBDEV-G-CROP; and &VIDIOC-SUBDEV-S-CROP; ioctls. Like for pad
+      formats, drivers store try and active crop rectangles. The format
+      negotiation mechanism applies to crop settings as well.</para>
+
+      <para>On input pads, cropping is applied relatively to the current pad
+      format. The pad format represents the image size as received by the
+      sub-device from the previous block in the pipeline, and the crop rectangle
+      represents the sub-image that will be transmitted further inside the
+      sub-device for processing. The crop rectangle be entirely containted

+    <title>Introduction</title>
+    <para>Media devices increasingly handle multiple related functions. Many USB
+    cameras include microphones, video capture hardware can also output video,
+    or SoC camera interfaces also perform memory-to-memory operations similar to
+    video codecs.</para>
+    <para>Independent functions, even when implemented in the same hardware, can
+    be modelled as separate devices. A USB camera with a microphone will be
+    presented to userspace applications as V4L2 and ALSA capture devices. The
+    devices' relationships (when using a webcam, end-users shouldn't have to
+    manually select the associated USB microphone), while not made available
+    directly to applications by the drivers, can usually be retrieved from
+    sysfs.</para>
+    <para>With more and more advanced SoC devices being introduced, the current
+    approach will not scale. Device topologies are getting increasingly complex
+    and can't always be represented by a tree structure. Hardware blocks are
+    shared between different functions, creating dependencies between seemingly
+    unrelated devices.</para>
+    <para>Kernel abstraction APIs such as V4L2 and ALSA provide means for
+    applications to access hardware parameters. As newer hardware expose an
+    increasingly high number of those parameters, drivers need to guess what
+    applications really require based on limited information, thereby
+    implementing policies that belong to userspace.</para>
+    <para>The media controller API aims at solving those problems.</para>
+  </section>

+  <section id="media-controller-model">
+    <title>Media device model</title>
+    <para>Discovering a device internal topology, and configuring it at runtime,
+    is one of the goals of the media controller API. To achieve this, hardware
+    devices are modelled as an oriented graph of building blocks called entities
+    connected through pads.</para>
+    <para>An entity is a basic media hardware or software building block. It can
+    correspond to a large variety of logical blocks such as physical hardware
+    devices (CMOS sensor for instance), logical hardware devices (a building
+    block in a System-on-Chip image processing pipeline), DMA channels or
+    physical connectors.</para>
+    <para>A pad is a connection endpoint through which an entity can interact
+    with other entities. Data (not restricted to video) produced by an entity
+    flows from the entity's output to one or more entity inputs. Pads should not
+    be confused with physical pins at chip boundaries.</para>
+    <para>A link is a point-to-point oriented connection between two pads,
+    either on the same entity or on different entities. Data flows from a source
+    pad to a sink pad.</para>

+        <para>This is the two-plane versions of the YUV 4:2:0 format where data
+is grouped into 64x32 macroblocks. The three components are separated into two
+sub-images or planes. The Y plane has one byte per pixel and pixels are grouped
+into 64x32 macroblocks. The CbCr plane has the same width, in bytes, as the Y
+plane (and the image), but is half as tall in pixels. The chroma plane is also
+grouped into 64x32 macroblocks.</para>
+        <para>Width of the buffer has to be aligned to the multiple of 128, and
+height alignment is 32. Every four adjactent buffers - two horizontally and two
+vertically are grouped together and are located in memory in Z or flipped Z
+order. </para>

+        The requirement that width is multiple of 128 is implemented because,

+of macroblocks is odd then the last row of macroblocks is arranged in a linear

+The three components are separated into three sub- images or planes.

+The Y plane is first. The Y plane has one byte per pixel. The Cb data
+constitutes the second plane which is half the width and half
+the height of the Y plane (and of the image). Each Cb belongs to four
+pixels, a two-by-two square of the image. For example,
+Cb<subscript>0</subscript> belongs to Y'<subscript>00</subscript>,
+Y'<subscript>01</subscript>, Y'<subscript>10</subscript>, and
+Y'<subscript>11</subscript>. The Cr data, just like the Cb plane, is
+in the third plane. </para>
+
+        <para>If the Y plane has pad bytes after each row, then the Cb
+and Cr planes have half as many pad bytes after their rows. In other
+words, two Cx rows (including padding) is exactly as long as one Y row

+
+    <para>This ioctl lets applications enumerate available frame intervals on a
+    given sub-device pad. Frame intervals only makes sense for sub-devices that
+    can control the frame period on their own. This includes, for instance,
+    image sensors and TV tuners.</para>
+
+    <para>For the common use case of image sensors, the frame intervals
+    available on the sub-device output pad depend on the frame format and size
+    on the same pad. Applications must thus specify the desired format and size
+    when enumerating frame intervals.</para>
+
+    <para>To enumerate frame intervals applications initialize the
+    <structfield>index</structfield>, <structfield>pad</structfield>,
+    <structfield>code</structfield>, <structfield>width</structfield> and
+    <structfield>height</structfield> fields of
+    &v4l2-subdev-frame-interval-enum; and call the
+    <constant>VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL</constant> ioctl with a pointer
+    to this structure. Drivers fill the rest of the structure or return
+    an &EINVAL; if one of the input fields is invalid. All frame intervals are
+    enumerable by beginning at index zero and incrementing by one until
+    <errorcode>EINVAL</errorcode> is returned.</para>
+
+    <para>Available frame intervals may depend on the current 'try' formats
+    at other pads of the sub-device, as well as on the current active links. See
+    &VIDIOC-SUBDEV-G-FMT; for more information about the try formats.</para>
+
+    <para>Sub-devices that support the frame interval enumeration ioctl should
+    implemented it on a single pad only. Its behaviour when supported on
+    multiple pads of the same sub-device is not defined.</para>

+    <para>This ioctl allows applications to enumerate all frame sizes

+    Supported formats can be retrieved with the &VIDIOC-SUBDEV-ENUM-MBUS-CODE;
+    ioctl.</para>

+

+
+    <para>For instance, to try a format at the output pad of a sub-device,

+
+    <para>Try formats do not depend on active formats, but can depend on the
