If you want to use Webcams, Video grabber devices and/or TV devices
enable this option and other options below.

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

---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.

Enable AM/FM radio support.
Additional info and docs are available on the web at

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.

bool "Software defined radio support"
---help---
Enable software defined radio support.
Say Y when you have a software defined radio device.
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.

This option enables DVB Network Support which is a part of the DVB
standard. 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. If
unsure say Y.

help
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.

# DVB device configuration

config DVB_MAX_ADAPTERS
int "maximum number of DVB/ATSC adapters"
depends on DVB_CORE
default 8
range 1 255
help
Maximum number of DVB/ATSC adapters. Increasing this number
increases the memory consumption of the DVB subsystem even
if a much lower number of DVB/ATSC adapters is present.
Only values in the range 4-32 are tested.
If you are unsure about this, use the default value 8
config DVB_DYNAMIC_MINORS
bool "Dynamic DVB minor allocation"
depends on DVB_CORE
default n
help
If you say Y here, the DVB subsystem will use dynamic minor
allocation for any device that uses the DVB major number.
This means that you can have more than 4 of a single type
of device (like demuxes and frontends) per adapter, but udev
will be required to manage the device nodes.
If you are unsure about this, say N here.

** Notes:
** ------

**
** *** write <buflen> bytes ***
** free = dvb_ringbuffer_free(rbuf);
** if (free >= buflen)
** count = dvb_ringbuffer_write(rbuf, buffer, buflen);
** else
** ...
**
** *** read min. 1000, max. <bufsize> bytes ***
** avail = dvb_ringbuffer_avail(rbuf);
** if (avail >= 1000)
** count = dvb_ringbuffer_read(rbuf, buffer, min(avail, bufsize));
** else
** ...
**
** (2) If there is exactly one reader and one writer, there is no need
** to lock read or write operations.
** Two or more readers must be locked against each other.
** Flushing the buffer counts as a read operation.
** Resetting the buffer counts as a read and write operation.
** Two or more writers must be locked against each other.

* GPL/Linux driver written by Patrick Boettcher <patrick.boettcher@desy.de>
*
* This driver is "hard-coded" to be used with the 1st generation of

*
* The driver works also with QAM64 DVB-C, but had an unreasonable high
* UNC. (Tested with the Air2PC ATSC 1st generation)
*
* You'll need a firmware for this driver in order to get it running. It is
