Tvheadend

h1. Traces - verbose debugging

It's quite usuall that a developer asks you to provide more verbose logs using the tracing subsystem which tvheadend includes. If you see --trace <comma_separated_list_of_subsystems> you need to follow this.

Compile tvheadend using --enable-trace option for the configure script see [[Building#Get-Source]] to compile tvheadend directly from sources. The traces are enabled by default, but packages - except debug versions - disables this functionality.

The first way to enable traces is from the command-line options (to specify the log file and all subsystems to debug), like:

<pre>

./build.linux/tvheadend -l /tmp/tvheadend.log --trace htsp,subscription,pat,pmt,bat

</pre>

The second way is to use the debugging tab in the configuration (this settings is not preserved):
