Using hybrid DVB-T/DVB-C-Stick with Linux, disabling the first frontend (frontend0)

Allgemein, VDR

I only wanted the DVB-C-Part of my stick (dvb_usb_rtl28xxu), but after VDR access the first frontend of this device (/dev/dvb/adapter0/frontend0), the device won’t be accessible on its other frontend (/dev/dvb/adapter0/frontend1), so I had to find a way to disable the first frontend.

If you have trouble scanning any channels, please take a look at you dmesg whether there was a problem loading the correct firmware. For me it looked like this:

user@host:~# dmesg | grep firmware
[23945257.415086] mn88473 7-0018: Direct firmware load for dvb-demod-mn88473-01.fw failed with error -2

Your firmware is most certainly somewhere in the github directory of OpenELEC: https://github.com/OpenELEC/dvb-firmware/tree/master/firmware

For example, I had to copy the dvb-demod-mn88473-01.fw to /lib/firmware/:

sudo wget https://github.com/OpenELEC/dvb-firmware/raw/master/firmware/dvb-demod-mn88473-01.fw -O /lib/firmware/dvb-demod-mn88473-01.fw

Check whether w_scan works:

sudo w_scan -fc -c DE >>dvb-c-channels.conf

Search for the DEVPATH of the frontend which you want to disable (for me it was adapter0/frontend0):

user@host:~# udevadm info --query=all --name=/dev/dvb/adapter0/frontend0 | grep DEVPATH
E: DEVPATH=/devices/pci0000:00/0000:00:14.0/usb3/3-4/dvb/dvb0.frontend0

Then add a new udev-rule as a new file /etc/udev/rules.d/11-disable-frontend0.rules:

ACTION=="add", SUBSYSTEM=="dvb", ENV{DVB_DEVICE_TYPE}=="frontend", DEVPATH=="/devices/pci0000:00/0000:00:14.0/usb3/3-4/dvb/dvb0.frontend0", ENV{dynamite_attach}="no"

I must admit that this didn’t work for me. I had to move the frontend0 manually to a higher number, disabling it by this for vdr:

user@host:~# mv /dev/dvb/adapter0/frontend0 /dev/dvb/adapter0/frontend9

VDR auf Server kompilieren, Einbindung von IPTV und Steuerung über KODI auf einem Client

Allgemein, VDR

Server mit Netzwerkanschluss hinter einem T-Entertain-Anschluss. An den Fernsehern im Haus liegt bereits Netzwerk und jeweils ein Raspberry PI oder ähnliches, um als Empfänger des VDR-Streams zu agieren. Auf den Clients läuft ein KODI (teilweise unter OpenELEC), welcher die Integration des VDR erleichtern soll. Es steckt allerdings keine DVB-T/DVB-C-Karte oder ähnliches im Server, sondern er soll die IPTV-Streams von der Telekom (T-Entertain/T-Home) nutzen. Dieses Vorgehen ist völlig legal. Einziger Nachteil bei dieser Vorgehensweise: Es gibt praktisch keine EPG-Daten aus dem Datenstrom, diese sind – bis auf „now“ und „next“ – verschlüsselt und können nur durch den von der Telekom bereitgestellten „Media Receiver“ entschlüsselt werden.

Der VDR wurde hierfür selbst kompiliert, um die notwendigen Plugins direkt nutzen zu können. Da es einige Zeit und Nerven gekostet hat, eine vernünftige Lösung hierfür zu finden, ist hier ein Skript zu finden, welches die vorausgesetzten Pakete installiert, alles herunterlädt und kompiliert.
