Additional info and docs are available on the web at <http://linuxtv.org> if MEDIA_SUPPORT comment "Multimedia core support" # # Multimedia support - automatically enable V4L2 and DVB core # config MEDIA_CAMERA_SUPPORT bool "Cameras/video grabbers support" ---help--- Enable support for webcams and video grabbers. Say Y when you have a webcam or a video capture grabber board. config MEDIA_ANALOG_TV_SUPPORT bool "Analog TV support" ---help--- Enable analog TV support. Say Y when you have a TV board with analog support or with a hybrid analog/digital TV chipset. Note: There are several DVB cards that are based on chips that support both analog and digital TV. Disabling this option will disable support for them. config MEDIA_DIGITAL_TV_SUPPORT bool "Digital TV support" ---help--- Enable digital TV support. Say Y when you have a board with digital support or a board with hybrid digital TV and analog TV. config MEDIA_RADIO_SUPPORT bool "AM/FM radio receivers/transmitters support" ---help--- Enable AM/FM radio support. Additional info and docs are available on the web at <http://linuxtv.org> Say Y when you have a board with radio support. Note: There are several TV cards that are based on chips that support radio reception. Disabling this option will disable support for them. config MEDIA_RC_SUPPORT bool "Remote Controller support" depends on INPUT ---help--- Enable support for Remote Controllers on Linux. This is needed in order to support several video capture adapters, standalone IR receivers/transmitters, and RF receivers. Enable this option if you have a video capture board even if you don't need IR, as otherwise, you may not be able to compile the driver for your adapter. Say Y when you have a TV or an IR device. # # Media controller # Selectable only for webcam/grabbers, as other drivers don't use it # config MEDIA_CONTROLLER bool "Media Controller API" depends on MEDIA_CAMERA_SUPPORT ---help--- Enable the media controller API used to query media devices internal topology and configure it dynamically.

It is used, for example, by automatic firmware updates used on Set-Top-Boxes. It can also be used to access the Internet via the DVB card, if the network provider supports it. You may want to disable the network support on embedded devices.

This is generally the right thing to do, except when there are strict constraints with regards to the kernel size, like on embedded systems. Use this option with care, as deselecting ancillary drivers which are, in fact, necessary will result in the lack of the needed functionality for your device (it may not tune or may not have the needed demodulators).
