Load required Modules
You have to lookup the chipset of your specific card; tools like lshwd may help you.
Pinnacle PCTV Sat
This card uses bt878 and cx24110 as chipset.
Load them (under root) with:
# modprobe dvb-bt8xx # modprobe cx24110
If you want Arch to boot them on startup, add both modules to MODULES
in /etc/rc.conf
.
Additional modules: S2-liplianin
However, there is not a working kernel module for all (especially newer) devices.
Igor M. Liplianin manages some additional modules at his mercurial repository.
Setup
First of all, you have to download and prepare the source code.
$ hg clone https://pikacode.com/liplianin/s2-liplianin
If you don't have installed mercurial, you will get an error message: hg: command not found
You can either download the package mercurial and try the obove command again or download the source code from here and extract it manually.
After obtaining the code, change the working directory to the extracted folder:
$ cd s2-liplianin
Unfortunately not all modules of liplianin are compatible with recent kernels and cause some trouble if you want to compile them hence you have to exclude these modules from the build process (if you do not need them). You can choose which modules you want to build by executing:
$ make config
which will create a config file: v4l/.config
.
Install
.After that, you have to build the chosen modules:
$ make
If all configured modules were compiled successfully, you can install the modules at the kernel's default modules directory by executing:
# make install
After that, reboot your machine.
Setup Permissions
To use your DVB-S card as user add him to the video
group:
# gpasswd -a [username] video
Scanning channels
Most applications like szap or xine are needing a channel list created by scan, which is part of dvb-utils. You will find the dvb-utils package under the name linuxtv-dvb-apps in the Community-Repo.
Install it with:
# pacman -S linuxtv-dvb-apps
Using scan
scan needs an channel to initialize scanning. In /usr/share/dvb/dvb-s/
are some files which contain these channels; you will need that one that fits the satellite you are watching from.
The following command will scan all channels and save them to channels.conf
:
$ scan -x0 -t1 -s1 /usr/share/dvb/dvb-s/[your satellite] | tee channels.conf
channels.conf
but it is more convenient as you will see later.Using w_scan
w_scan allows for automatic scanning of channels without configuration. Install it then issue:
# w_scan -c [your country] > ~/someChannels.conf
Alternatively you can also scan using the satellite position like 19.5E for Astra 1. Scans like that can be done as follows:
# w_scan -fs -s S19E5 > ~/someChannels.conf
You can also add the -X flag to generate tzap/czap/xine output instead of vdr output.
# w_scan -X -c AU > ~/AustraliaChannels.conf
DiSEqC switch scanning (AKA multiple satellite LNB)
If you have a LNB with a DiSEqC switch in it you can manually select that using the -D option like so:
# w_scan -fs -s S23E5 -D 1c > ~/someChannels.conf
The above line should work but not all found channels where actually saved. The line below worked perfectly for me:
# w_scan -fs -s S23E5 -a 0 -D 1c -o 7 -e 2 > ~/someChannels.conf
Switching channels
By using zap, which comes with dvb-utils, you can switch channels, so you do not have to rely on the abilities of your player.
szap needs the channel file we created earlier; it will try ~/.szap/channels.conf
by default. You can move the channels.conf
there or you can use the "-c"
command-line option.
Switching channels works like this:
$ szap -r [channel]
You can list all available channels with:
$ szap -q
Now you can watch the stream for example with xine:
$ xine -g stdin://mpeg2 < /dev/dvb/adapter0/dvr0
or with mplayer:
$ mplayer /dev/dvb/adapter0/dvr0
or with mplayer, but using DVB directly:
$ mplayer "dvb://RTL Television"
You can find all the channel names by running szap -q (assuming the channel list is also in ~/.szap/channels.conf).
Software
Kaffeine
Kaffeine is a really nice player; it supports EPG, time-shifting, and recording. Additionally Kaffeine has built-in channel-searching.
Install it with:
# pacman -S kaffeine
Importing channel list
- Linosaw.de provides channels.conf files for VDR
- conv2conf converts these files into kaffeine channel list format
Me-tv
Me-tv is a simple but powerfull dvb-viewer, supporting EPG, recording and channel-searching with a light-weight gui.
- It is in the official repository:
# pacman -S me-tv
- SVN version in the AUR: https://aur.archlinux.org/packages.php?ID=27065
Klear
Klear is also a really nice player, but more than 4 years old (last release 2006). It supports EPG, time-shifting, and recording, videotext. Channel-searching is still missing. Install it from AUR:
Xine
Copy your channel file to ~/.xine/channels.conf
.
Watch a specific channel with following command:
$ xine dvb://[channel]
or use the playlist editor in Xine
