Tvheadend gets stuck with TBS5881

Pepe Suriano

Hi people, I am getting some trouble with my TBS5881 and tvheadend, I installed media_build drivers from ljalves which runs fine, but when I turn on my raspberry pi, tvheadend gets stucked and it never starts

Here are logs with and without tbs plugged for being more specifical:

same thing happens to me with libreelec, openelec, and ubuntu 14.04 on my RPI

what could be the problem? I tested several different versions of tvheadend, even 4.1-2000-09.05.2016, but i have no luck

try running with --trace all --debug all :p

Are you able to installscan (dvb-apps) at all on your system? If you can try scanning using that, if that hangs too it suggests a driver problem..

Hi Mark, I have no plenty of experience scanning with dvb_apps, but I think that it could be a driver problem as you suggest, I ran this:

LibreELEC:~ # ls /dev/dvb/ adapter0 LibreELEC:~ # scan -C -a 0 scanning 0 using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' Segmentation fault

Is it Ok that test?

If it is a driver problem, how could I debug it?

P.D.: Tried --trace all --debug all but it displays exactly the same:



LibreELEC:~ # /storage/.kodi/addons/service.tvheadend42/bin/tvheadend  --trace a
ll --debug all

You'd have to ask ljalves for help, you won't get any from TBS as you're using an unofficial driver. Even so without the hardware I don't think he'll be able to do much but it doesn't hurt to ask him..

I actually gave him access to my system so he could look into how the driver worked, and write his own for the TBS 5922 which the last time I tried it ran perfectly on an RPi (I know this doesn't help you much).

In fact it was a driver problem, I tried
https://bitbucket.org/CrazyCat/media_build.git
(crazycat driver) and now tvheadend starts and shows the tuner OK! It shows both si2168 dvbt and dvbc

Now I have the problem that I am not able to scan, at debug window of tvheadend I get "2016-05-10 11:58:06.001 linuxdvb: Silicon Labs Si2168 : DVB-C #0 - failed to tune [e=Invalid argument]"

In my desktop PC I have tvheadend running OK with TBS drivers, and I use the following info to scan:

Delivery system: DVBC/ANNEX_B
Frecuency (Hz): 375000000
Symbol rate (sym/s): 5360000
constellation: qam256

fec: auto

but after scanning, tvheadend seems to modify some fields, and it finally sets with that info:

Delivery system: DVBC/ANNEX_A
Frecuency (Hz): 375000000
Symbol rate (sym/s): 5360000
constellation: qam256

fec: 3/5

I tried to scan with annex_b data (the first example, which works fine on my desktop pc) and I get the invalid argument error

And I also scanned with annex_a data (the second example, in which part of the info is edited by tvheadend comparing with the info that I put first) then I got:

2016-05-10 11:57:09.046 linuxdvb: Unable to provide BER value.

2016-05-10 11:57:09.046 linuxdvb: Unable to provide SNR value.

2016-05-10 11:57:09.046 linuxdvb: Unable to provide UNC value.

2016-05-10 11:57:10.000 mpegts: 375MHz in Newnetwork - scan no data, failed

what could be bad?
