i need to enable debugging to get to the bottom of a problem

hi,

my setup is ubuntu server running tvheadend in a docker container using IPTV as a source, serving tv to kodi on libreelec on a rpi3 client.

For the most parts its great now ive realised how to manage the channels properly, but I have a problem with discontinuity errors which causes freezes, switching channel and then back to the original solves the problem until it happens again, i've tried kodi on a windows 10 laptop and an xbox one s with the same errors appearing.

The strange thing is if I use the tvheadend app on IOS and use the rpi3 as the target player its faultless, no errors in the log and no freezing at all.

I realise I need to provide logs for this but I cant figure out how to do this, i enter a path in the debugging window,but nothing gets written to the file.

thanks

scott

in "Debug subsystems" you need to enter a comma separated list of which subsystems to debug:

Or you can use "all" for everything.

For more in depth debugging, you can enable "Debug trace (low-level):" and enter the subsystems as above.

You can also use negative values (ie, -epg) to remove things after an "all".

all,-epg

after applying it will return with a list of all subsystems except epg.

great thanks i have it logging now, not sure which subsystem other than mpegts and tsfix I need to log though?

RE: i need to enable debugging to get to the bottom of a problem - Added by Joe User about 5 years ago

When I don't know what subsystems, I usually start with all and slowly remove some which I notice I don't need:
all
all,-x
all,-x,-y
all,-x,-y,-z
...

I don't use IPTV, but probably iptv and mpegts are needed if you want to start with less an build up instead...
