# LIBDDDVB
The libdddvb provides a userspace library to simplify tuning and
CI use. It detects DVB cards and their capabilities and selects
free frontends depending on a given delivery system.
In order to install the libdddvb library you need the dvben50221.
On an Ubuntu and other Debian based system you can install it like this:
`sudo apt-get install dvb-apps`
After that you can build the libdddvb:
`git clone https://github.com/DigitalDevices/dddvb.git`
`cd dddvb/lib/; make`
`sudo make install`
If your distribution does not include a dvb-apps package, you can follow the
instructions at
https://www.linuxtv.org/wiki/index.php/LinuxTV_dvb-apps
on how to build it yourself.
# DDZAP
You can now use the example program ddzap to see how the library
is used or to test your cards.
A typical usage example would be the tuning of a
sattelite channel with a given LNB configuration.
`ddzap -d S2 -p h -f 11494000 -s 22000000 -c ~/dddvb/lib/config/`
where you would use the example configuration file for a unicable LNB
given in the sources. If you leave out the `-c` option a standard universal
LNB is assumed to be connected.
Additionally you can use ddzap to open the /dev/dvb/adaptorX/dvrY device
that corresponds to the tuner that was automatically selected by the library
and pipe it to a media player, e.g.
`ddzap -d S2 -p h -f 11494000 -s 22000000 -c /home/dmocm/ddzapconf/ -o|vlc -`
