systemd configuration
Added by neik neik almost 12 years ago
Hey together,
I installed a tvheadend on fedora 18 under xbmc and everything is working well. there is one single problem. I can't get tvheadend start probably automatically after boot. The systemd starts the tvheadend and then the deamon crashs without any detailed information. I searched for systemd examples and tried something with tvheadend.service examples, but I can't get it work.
My tvheadend cconfigration file:
- begin file ###
[Unit]
Description=tvheadend
Wants=network.target
[Service]
User=USERNAME
Type=forking
ExecStart=/usr/local/bin/tvheadend-3.2.18/build.linux/tvheadend -f -u USERNAME -g GROUPNAME
[Install]
WantedBy=multi-user.target
- end file ###
the file ist stored under /etc/systemd/system/tvheadend.service
one second interesting point is that I am able to start the deamon with this command with this user without any problems.
any ideas?
best regards
neik

Hello,
I have tried tvheadend on arch linux. It is started from systemd and I have not experienced issues like this.
On arch the package adds an hts user and the daemon is running with these three parameters
-c -u hts -g video
The only difference is the -f parameter. Otherwise can tvheadend access dvb devices?
Here is the aur entry if you would like to have a look...

Hi,
for me this works fine:
[Unit] Description=tvheadend Wants=network.target After=network.target # Whats oscam? #Wants=oscam.service #After=oscam.service # Wants: would like to have, After: start after, Requires: needs [Service] User=root # tvheadend nees root priv to create pid file and switch to user hts. #Group= Type=forking PIDFile=/run/tvheadend.pid ExecStart=/usr/bin/tvheadend -f -p /run/tvheadend.pid -u hts -g video ExecStop=/usr/bin/rm /run/tvheadend.pid Restart=always RestartSec=5 [Install] WantedBy=multi-user.target [Service] Type=forking
Got most of it from:

Well...
Manually starting works: "systemctrl start tvheadend"
But automatic start does not work yet. Tried "systemctrl enable tvheadend", let's see if this helps.
Suspend scripts:
$ cat /etc/systemd/system/suspend.target.wants/tvheadend-resume.service [Unit] Description=Restart TVHeadend on suspend/hibernate/hybrid After=suspend.target After=hibernate.target After=hybrid-sleep.target [Service] Type=simple ExecStart=/bin/systemctl start tvheadend [Install] WantedBy=suspend.target WantedBy=hibernate.target WantedBy=hybrid-sleep.target $ cat /etc/systemd/system/suspend.target.wants/tvheadend-suspend.service [Unit] Description=Stop TVHeadend on suspend/hibernate/hybrid Before=sleep.target [Service] Type=simple ExecStart=/bin/systemctl stop tvheadend [Install] WantedBy=sleep.target
Stop/Start works now, but it cannot record. No Stream. /dev/dvb/adapter0 exists... maybe I have to reload the modules. How do I do that in systemd?
Does anybody understand why this is working? What exactly is going on?

Personally didn't realise that systemd supported sleep/wake stuff, but I guess that does make sense.
Not an answer to your systemd specific question, but I'm running tvheadend on Ubuntu 15.04 with systemd (albeit wrapping the init.d
and using service
) and just use my own version of the sleep/wake script that's listed in the forums. This does require an install of pm-utils and, yeah, you do have to unload/load the modules. My current script, for 3xDVBSky T9580s, /etc/pm/sleep.d/99_htpc.sh
is as follows:
#!/bin/bash case "$1" in suspend|hibernate) service tvheadend stop sleep 3 modprobe -v -r smipcie si2168 m88ds3103 ;; resume|thaw) modprobe -v smipcie sleep 1 service tvheadend start ;; esac
I would guess similar works using systemctl
instead of service
, but I'd be interested too how you achieve the same module-business with systemd "natively".
As a (general) aside - hope you don't have TBS adapters. It seems some folk have these working with sleep/wake, but I found my ones a world of pain with the OS drivers - could never get them working properly on resume (amongst having other issues). Gave up in the end and replaced them - the DVBSky cards have been great.

Because of this problem and some more, I did a fresh install of Kubuntu 16.04.
Waking up Tvheadend after standby works out of the box now.
What doesn't work is waking up from standby for scheduled recordings. I am working on it.
RE: systemd configuration - Added by Robin Mitra about 8 years ago
My suggestion is:
- Tvheadend maintains a systemd.timer (with the wake flag enabled)
- this timer gets updated either everytime the internal scheduled tasks change (i.e. the timer contains the date/time of the next task tvh needs perform, that copuld be recording or scan, or whatever...)
or in the tvh suspend task itself.
- whenever the timer is updated, don't forget to issue a systemctl daemon-reload
- and yes that works also in the tvh suspend unit
This way of way of setting a wake time when the system suspends works. Unfortunately, the drivers don't really like suspend resume, and even removing them on suspend, reloading them on resume doesn't seem to work properly. The dependencies are a mess (ddbridge, in my case).
Also, IMHO tvh should prevent sleep when it has do to something and reallow when idle (can be done via d-bus/logind).
what remains is who is responsible for putting the system to sleep, powertop?
