21 config MEDIA_CAMERA_SUPPORT
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.
40 config MEDIA_DIGITAL_TV_SUPPORT
41 bool "Digital TV support"
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.
48 config MEDIA_RADIO_SUPPORT
49 bool "AM/FM radio receivers/transmitters support"
51 Enable AM/FM radio support.

56 Say Y when you have a board with radio support.
58 Note: There are several TV cards that are based on chips that
59 support radio reception. Disabling this option will
60 disable support for them.
62 config MEDIA_SDR_SUPPORT
63 bool "Software defined radio support"
65 Enable software defined radio support.
67 Say Y when you have a software defined radio device.
69 config MEDIA_RC_SUPPORT
70 bool "Remote Controller support"
73 Enable support for Remote Controllers on Linux. This is
74 needed in order to support several video capture adapters,
75 standalone IR receivers/transmitters, and RF receivers.
77 Enable this option if you have a video capture board even
78 if you don't need IR, as otherwise, you may not be able to
79 compile the driver for your adapter.
81 Say Y when you have a TV or an IR device.
83 config MEDIA_CEC_SUPPORT
84 bool "HDMI CEC support"
87 Enable support for HDMI CEC (Consumer Electronics Control),
88 which is an optional HDMI feature.
90 Say Y when you have an HDMI receiver, transmitter or a USB CEC
91 adapter that supports HDMI CEC.
93 config MEDIA_CEC_DEBUG
94 bool "HDMI CEC debugfs interface"
95 depends on MEDIA_CEC_SUPPORT && DEBUG_FS
97 Turns on the DebugFS interface for CEC devices.

107 config MEDIA_CONTROLLER
108 bool "Media Controller API"
109 depends on MEDIA_CAMERA_SUPPORT || MEDIA_ANALOG_TV_SUPPORT || MEDIA_DIGITAL_TV_SUPPORT
111 Enable the media controller API used to query media devices internal
112 topology and configure it dynamically.
114 This API is mostly used by camera interfaces in embedded platforms.
116 config MEDIA_CONTROLLER_DVB
117 bool "Enable Media controller for DVB (EXPERIMENTAL)"
118 depends on MEDIA_CONTROLLER && DVB_CORE
120 Enable the media controller API support for DVB.
122 This is currently experimental.

137 depends on VIDEO_DEV && MEDIA_CONTROLLER
139 Enables the V4L2 sub-device pad-level userspace API used to configure
140 video format, size and frame rate between hardware blocks.

161 depends on NET && INET && DVB_CORE
163 This option enables DVB Network Support which is a part of the DVB
164 standard. It is used, for example, by automatic firmware updates used
165 on Set-Top-Boxes. It can also be used to access the Internet via the
166 DVB card, if the network provider supports it.
168 You may want to disable the network support on embedded devices. If

206 bool "Autoselect ancillary drivers (tuners, sensors, i2c, spi, frontends)"
207 depends on MEDIA_ANALOG_TV_SUPPORT || MEDIA_DIGITAL_TV_SUPPORT || MEDIA_CAMERA_SUPPORT || MEDIA_SDR_SUPPORT
213 By default, a media driver auto-selects all possible ancillary
214 devices such as tuners, sensors, video encoders/decoders and
215 frontends, that are used by any of the supported devices.
217 This is generally the right thing to do, except when there
218 are strict constraints with regards to the kernel size,
219 like on embedded systems.
221 Use this option with care, as deselecting ancillary drivers which
222 are, in fact, necessary will result in the lack of the needed
223 functionality for your device (it may not tune or may not have
224 the needed demodulators).
