# Can be downloaded and installed in one go by using this command
#  sudo wget -O /tmp/download https://gist.github.com/DaveThw/cf4aa638a03fdedfcd05/download && sudo tar -zxf /tmp/download --strip-components 1 -C /etc/init.d && sudo chmod +x /etc/init.d/get_iplayer_web && sudo update-rc.d get_iplayer_web defaults

# Or download and just move to /etc/init.d using this command
#  sudo wget -O /tmp/download https://gist.github.com/DaveThw/cf4aa638a03fdedfcd05/download && sudo tar -zxf /tmp/download --strip-components 1 -C /etc/init.d && sudo chmod +x /etc/init.d/get_iplayer_web
# and then start/stop/restart the service with these commands
#  sudo service get_iplayer_web stop
#  sudo service get_iplayer_web start
#  sudo service get_iplayer_web restart
# And then, if/when you want the service to autostart on bootup, use this
#  sudo update-rc.d get_iplayer_web defaults
# Conversely, if you want to stop the service autostarting on bootup, use this
#  sudo update-rc.d -f get_iplayer_web remove

# This script is based on my version of the Node-RED init.d script, here: https://gist.github.com/DaveThw/da394c8d04fa2bba55ac


# User that launches get_iplayer_web (it's advised to create a new user)
#  You can do:
#   sudo useradd iplayer-web
#  then change line below from  USER=pi  to  USER=iplayer-web
USER=pi

# The interface address to listen on for webpage requests:
#  Use  LISTEN=0.0.0.0    to listen on any/all interfaces (not very secure - use on trusted local network only - don't expose to the internet!)
#  Use  LISTEN=127.0.0.1  to only accept requests from this computer
LISTEN=0.0.0.0

# The port to listen on for webpage requests:
PORT=1935


# DON'T CHANGE anything below this line unless you know what you're doing!

Hi,

I've just used this script to run the web pvr a daemon on OSMC. I'm running the daemon as user osmc, and only changed the name of the daemon. It seems to run fine in that I can access the web page and the pvr manager adds programmes. However, when checking the status of the daemon after launch, I am presented with the following lines:

Sep 09 12:46:25 osmc get_iplayer_web_pvr[17193]: Starting daemon: get_iplayer_web_pvrstart-stop-daemon: warning: this system is not able to track process names
Sep 09 12:46:25 osmc get_iplayer_web_pvr[17193]: longer than 15 characters, please use --exec instead of --name.
Sep 09 12:46:25 osmc get_iplayer_web_pvr[17193]: /etc/init.d/get_iplayer_web_pvr: invalid arguments
Sep 09 12:46:25 osmc get_iplayer_web_pvr[17193]: failed!

I'm struggling to see which arguments are apparently invalid, and what has failed. Any clue/help?

Thanks for the script.
