58 <para>This ioctl lets applications enumerate available frame intervals on a
59 given sub-device pad. Frame intervals only makes sense for sub-devices that
60 can control the frame period on their own. This includes, for instance,
61 image sensors and TV tuners.</para>
62
63 <para>For the common use case of image sensors, the frame intervals
64 available on the sub-device output pad depend on the frame format and size
65 on the same pad. Applications must thus specify the desired format and size
66 when enumerating frame intervals.</para>
67
68 <para>To enumerate frame intervals applications initialize the
69 <structfield>index</structfield>, <structfield>pad</structfield>,
70 <structfield>code</structfield>, <structfield>width</structfield> and
71 <structfield>height</structfield> fields of
72 &v4l2-subdev-frame-interval-enum; and call the
73 <constant>VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL</constant> ioctl with a pointer
74 to this structure. Drivers fill the rest of the structure or return
75 an &EINVAL; if one of the input fields is invalid. All frame intervals are
76 enumerable by beginning at index zero and incrementing by one until
77 <errorcode>EINVAL</errorcode> is returned.</para>
78
79 <para>Available frame intervals may depend on the current 'try' formats
80 at other pads of the sub-device, as well as on the current active links. See
81 &VIDIOC-SUBDEV-G-FMT; for more information about the try formats.</para>
82
83 <para>Sub-devices that support the frame interval enumeration ioctl should
84 implemented it on a single pad only. Its behaviour when supported on
85 multiple pads of the same sub-device is not defined.</para>

59 <para>These ioctls are used to get and set the frame interval at specific
60 subdev pads in the image pipeline. The frame interval only makes sense for
61 sub-devices that can control the frame period on their own. This includes,
62 for instance, image sensors and TV tuners. Sub-devices that don't support
63 frame intervals must not implement these ioctls.</para>
64
65 <para>To retrieve the current frame interval applications set the
66 <structfield>pad</structfield> field of a &v4l2-subdev-frame-interval; to
67 the desired pad number as reported by the media controller API. When they
68 call the <constant>VIDIOC_SUBDEV_G_FRAME_INTERVAL</constant> ioctl with a
69 pointer to this structure the driver fills the members of the
70 <structfield>interval</structfield> field.</para>
71
72 <para>To change the current frame interval applications set both the
73 <structfield>pad</structfield> field and all members of the
74 <structfield>interval</structfield> field. When they call the
75 <constant>VIDIOC_SUBDEV_S_FRAME_INTERVAL</constant> ioctl with a pointer to
76 this structure the driver verifies the requested interval, adjusts it based
77 on the hardware capabilities and configures the device. Upon return the
78 &v4l2-subdev-frame-interval; contains the current frame interval as would be
79 returned by a <constant>VIDIOC_SUBDEV_G_FRAME_INTERVAL</constant> call.
80 </para>
81
82 <para>Drivers must not return an error solely because the requested interval
83 doesn't match the device capabilities. They must instead modify the interval
84 to match what the hardware can provide. The modified interval should be as
85 close as possible to the original request.</para>
