If you are intending to do Tvheadend development or simply self-building / testing then this page gives a few useful hints and tips.
If you intend to build and test tvheadend its recommended that you do this as your own user, it'll make things a lot easier and can help isolate a test build from your main live build.
You will need to give your user account the necessary permissions to access the DVB hardware:
sudo usermod -a -G video $(id -nu)
If you already have an existing configuration you might consider taking a copy of this to give you a realistic data set without tainting your main config:
sudo cp -a ~hts/.hts/tvheadend/ ./test-conf sudo chown -R $(id -nu):$(id -ng) ./test-conf
Enable coredumps (this is best put in shell init script):
ulimit -c unlimited
You should now be able to run tvheadend as yourself (remember to turn off the main tvheadend service):
mkdir -p test-conf ./build.linux/tvheadend -c ./test-conf
For more general information about debugging please read this page.
