Tvheadend

Hi,

I'm migrating from an Ubuntu server pc to a RaspberryPi 2 setup (Debian Jessie). I bought two USB DVB-C tuners (Optimuss, the same as the Techonotrend TT-TVStick CT2-4400: http://www.linuxtv.org/wiki/index.php/TechnoTrend_TT-TVStick_CT2-4400#Driver_support).

lsusb lists both tuners and in TvHeadend I can see both tuners. I've added the network (Ziggo Netherlands) and let it scan for muxes/services. Unfortunately no services are found. Same results from the cli with w_scan.

The question. The link above mentions installing [http://www.linuxtv.org/wiki/index.php/TechnoTrend_TT-TVStick_CT2-4400#Firmware[firmware]]. Is this still necessary when TvHeadend already recognizes the tuners ?

Thanks !

In most cases yes.

The driver is able to see the device without the firmware but it is required to function, it gets uploaded to the device either at boot or on first tune.

Thanks for the reply Mark. I will give it try this evening.

Just to add. Look at dmesg output when starting tvheadend. It will usually complain that it cannot find firmware in such cases. I have seen it with many different cards. Ie the card is recognised, but does not function without firmware.

Downloaded the drivers from here http://www.linuxtv.org/wiki/index.php/TechnoTrend_TT-TVStick_CT2-4400#Firmware[firmware (dmesg shows what drivers it tries to load). Placed them in /lib/firmware and both tuners work. No issues so far, the rpi2 performs very well.

Next issue: I'm trying to get tv_grab_nl to work. Problem is: I log in as user pi but tvheadend runs under user hts. How do I --configure tv_grab_nl as user hts ?

try

sudo -u hts /bin/bash

Make sure you're in the correct home directory though, do 'ls -a' & you should see .hts, if not just cd to /home/hts.
