22 bool "Cameras/video grabbers support"
24 Enable support for webcams and video grabbers.
26 Say Y when you have a webcam or a video capture grabber board.
28 config MEDIA_ANALOG_TV_SUPPORT
29 bool "Analog TV support"
31 Enable analog TV support.
33 Say Y when you have a TV board with analog support or with a
34 hybrid analog/digital TV chipset.
36 Note: There are several DVB cards that are based on chips that
37 support both analog and digital TV. Disabling this option
38 will disable support for them.

43 Enable digital TV support.
45 Say Y when you have a board with digital support or a board with
46 hybrid digital TV and analog TV.

58 Note: There are several TV cards that are based on chips that
59 support radio reception. Disabling this option will

62 config MEDIA_RC_SUPPORT
63 bool "Remote Controller support"
66 Enable support for Remote Controllers on Linux. This is
67 needed in order to support several video capture adapters,
68 standalone IR receivers/transmitters, and RF receivers.
70 Enable this option if you have a video capture board even
71 if you don't need IR, as otherwise, you may not be able to
72 compile the driver for your adapter.
74 Say Y when you have a TV or an IR device.

82 bool "Media Controller API (EXPERIMENTAL)"
83 depends on EXPERIMENTAL
84 depends on MEDIA_CAMERA_SUPPORT
86 Enable the media controller API used to query media devices internal
87 topology and configure it dynamically.
89 This API is mostly used by camera interfaces in embedded platforms.

106 Enables the V4L2 sub-device pad-level userspace API used to configure
107 video format, size and frame rate between hardware blocks.

130 This option enables DVB Network Support which is a part of the DVB
131 standard. It is used, for example, by automatic firmware updates used
132 on Set-Top-Boxes. It can also be used to access the Internet via the
133 DVB card, if the network provider supports it.
135 You may want to disable the network support on embedded devices. If

174 bool "Autoselect ancillary drivers (tuners, sensors, i2c, frontends)"
175 depends on MEDIA_ANALOG_TV_SUPPORT || MEDIA_DIGITAL_TV_SUPPORT || MEDIA_CAMERA_SUPPORT
178 By default, a media driver auto-selects all possible ancillary
179 devices such as tuners, sensors, video encoders/decoders and
180 frontends, that are used by any of the supported devices.
182 This is generally the right thing to do, except when there
183 are strict constraints with regards to the kernel size,
184 like on embedded systems.
186 Use this option with care, as deselecting ancillary drivers which
187 are, in fact, necessary will result in the lack of the needed
188 functionality for your device (it may not tune or may not have
189 the needed demodulators).
