# 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 -`
