By default, a media driver auto-selects all possible ancillary
|
|
devices such as tuners, sensors, video encoders/decoders and
|
|
frontends, that are used by any of the supported 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).
|
|
|
|
If unsure say Y.
