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.

Please note that the libdddvb library and the ddzap tool are provided as examples and for testing purposes.

In order to install the libdddvb library you need the libdvben50221.

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 -
