crashed the config - need help to recover

Sulla Sulla

dear all!

I crashed my config: I wanted to add an IPTV-mux (rtsp-stream), and tvheadend (running on debian bullseye x64) now crashes.

What I did was:
I added a new "IPTV Network". This seemd to work normally.

I added a new "mux" giving the url of the rtsp stream. This caused TVheadend to somehow crash:

=============
sudo service tvheadend status
tvheadend.service - Tvheadend - a TV streaming server and DVR
Loaded: loaded (/lib/systemd/system/tvheadend.service; enabled; vendor preset: enabled)

Process: 2273 ExecStart=/usr/bin/tvheadend -f -p /run/tvheadend.pid $OPTIONS (code=exited, status=0/SUCCESS)
Main PID: 2274 (code=killed, signal=SEGV)

May 20 19:29:34 freedom systemd[1]: tvheadend.service: Consumed 2.942s CPU time.

=============

when the linux-service restarts, the web-interface comes up briefly, but does not load any tv-adapters nor networks nor muxes, then crashes again.

is there a way to undo this, eg delete the mux from commandline?

thanx for support, Sulla

I believe the iptv configuration is in /home/hts/.hts/tvheadend/input/iptv/networks. If you move the contents of that directory somewhere else then maybe you will be able to restart Tvheadend.

great, that worked! Thanx a lot!

I'm just reading an older thread about how to recover from the automatic backups in ~/.hts/tvheadend/backups but my last backup would have been half a year old...

Don't forget to test your backup!
