Need a little help with custom remote xml

Mmz · 30. Juli 2017

Hi there,
I recently have setup all my hardware and it is working great
Setup:
RPi3 with LibreELEC running Hyperion installed via HyperCon

Now that everything is setup, I recognized the daemon always points to one single configuration file and the Hyperion App for Android doesn't provide an easy way to toggle between several configuration files.

So I wrote a little script (quick 'n dirty), which will read out my AVR's xml to see which hdmi-source is active (all in bash :sickxx: has been a pain in the ass...) and will allow me to toggle between internal and external grabber (if called with arguments). I named it 'htoggle'.
Since libreELEC is designed in a very restrictive way, I'm not sure if I somehow will be able to run this as a daemon, so I decided to toggle by hand via CEC remote for now.

This is my script, running nice from within ssh sessions:

Code

#!/usr/bin/env bash
# get hdmi-source
# stdin workaround:
tmp="/storage/.kodi/temp/hdmisource.txt"
curl http://192.168.178.7/goform/formMainZone_MainZoneXmlStatusLite.xml >> $tmp 2>/dev/null
sed -ne '/InputFuncSelect/{s/.*<InputFuncSelect>\(.*\)<\/InputFuncSelect>.*/\1/p;q;}' -i $tmp
sed -ne '/value/{s/.*<value>\(.*\)<\/value>.*/\1/p;q;}' -i $tmp
snippet=$(cat $tmp)
if [ "$snippet" == "BD" ]; then # my kodi media center
  conf="/storage/.config/int_ext_hyperion.config.json"
else
  conf="/storage/.config/ext_only_hyperion.config.json"
fi
rm $tmp
# debug
echo $snippet --- $conf
# htoggle w/o arguments
if [ "$1" == "" ]; then
# if on, turn off
  if [ `pidof hyperiond` > "0" ]; then
  killall hyperiond 2>/dev/null
  fi
  /storage/hyperion/bin/hyperiond.sh $conf > /storage/logfiles/hyperion.log 2>&1 &
fi
# htoggle w/ argument 'off'
if [ "$1" == "off" ]; then
# if on, turn off
  if [ `pidof hyperiond` > "0" ]; then
  killall hyperiond 2>/dev/null
  fi
fi
exit 0

Now I barely understand, how to modify libreELECS remote keymapping. I cannot get access to these infos, because kodi.wiki is offline since a few days and all of my web search results point to this wiki.

I want to alter the mapping for my CEC Remote (the color keys which I don't need) to execute "htoggle" and "htoggle off".

I thought it would be enough, to modify .kodi/userdata/advancedsettings.xml and include a tag like this:

XML

<?xml version="1.0" encoding="UTF-8"?>
<advancedsettings>
<keymap>
  <global>
    <remote>
      <red>ActivateWindow(Videos)</red>
      <green>ActivateWindow(Videos)</green>
      <yellow>ActivateWindow(Videos)</yellow>
      <blue>ActivateWindow(Videos)</blue>
    </remote>
  </global>
</keymap>
</advancedsettings>

Alles anzeigen

In this example I set everything to ActivateWindow(Videos) for testing purposes.
As long as I understand, now the original global part from original (untouched) remote.xml should be replaced by my modification.

But it does not work. kodi seems to ignore my advancedsettings.xml, even if I can see it loads:

Code

LibreELEC:~ # cat .kodi/temp/kodi.log
[...]
16:45:30.660 T:1962662016  NOTICE: Contents of special://profile/advancedsettings.xml are...

                                                  </remote>

What am I missing? Isn't this the proper way to modify key actions on a CEC remote?

Mmz · 31. Juli 2017

I modified my script to run as "daemon", checking each 5 seconds for two flags in /tmp (1st flag to see if hdmi source changed, which will result in picking the right Hyperion configuration file, 2nd flag to see if user wants LEDs/Hyperion to be on or off, so I no longer need the CEC Remote thing.

If someone wonders why I did all this:
I'm not sure if this is how it was intended to be, but the official Hyperion app from Google Playstore has no working "turn LEDs off"-button for me. It just resets the colorwheel and effects and so on but does NOT turn the LEDs off, which I find is not the way it should run. Second, as I yet mentioned this app doesn't provide a way to toggle between several configuration files for Hyperion, which I find necassary, because a) I want to switch between internal and external grabber and b) the USB-Video-Grabber does not provide the exact same colors than the HDMI-Source for each source, so I want to have the ability to auto-switch between several pre-stored configurations.

Of course, this is specifically designed to work with my Denon AVR's xml, but if someone somehow is interested in the whole thing, may be because he owns an AVR with readable xml files as well, here it is:

Turn Hyperion on / off:
Name: h-toggle
(I run this script by Android app "RasPi Check" as stored command, much more comfortable than using Juice SSH)

Code

#!/usr/bin/env bash
# This script needs script 'which-h-grabber' as daemon to turn Hyperion on and off!
if [ -f "/tmp/h-off" ]; then
    rm /tmp/h-off
echo "Hyperion ON"
else
    touch /tmp/h-off
    echo "Hyperion OFF"
fi
exit 0

Check which source is selected in AVR and if LEDs should be on or off:
Name: which-h-grabber

Code

#!/usr/bin/env bash
#  # if another script is telling you, that LEDs shall be turned off...
if [ -f "/tmp/h-off" ]; then
    if [ `pidof hyperiond` > "0" ]; then
        killall hyperiond 2>/dev/null
# debug
        echo "Found OFF-Flag in /tmp - Turned LEDs OFF"
    else
#debug
        echo "Found OFF-Flag in /tmp - Nothing to do"
    fi
    exit 0
fi


# get hdmi-source
# check for changing hdmi source
tmp="/tmp/hdmisource.txt"
if [ ! -f $tmp ]; then touch $tmp;fi;


# Step 1 - get old (or first) hdmi source from existing file from tmpfs and store as $source_t1
source_t1=$(cat $tmp)


# Step 2 - get new hdmi source from AVR XML and store in file on tmpfs and store as $source_t2
curl http://192.168.178.7/goform/formMainZone_MainZoneXmlStatusLite.xml >> $tmp 2>/dev/null
sed -ne '/InputFuncSelect/{s/.*<InputFuncSelect>\(.*\)<\/InputFuncSelect>.*/\1/p;q;}' -i $tmp
sed -ne '/value/{s/.*<value>\(.*\)<\/value>.*/\1/p;q;}' -i $tmp
source_t2=$(cat $tmp)


# Step 3 - Choose Hyperion configuration file, that matches recent $source_t2
if [ "$source_t2" == "BD" ]; then # my kodi media center
        conf="/storage/.config/int_ext_hyperion.config.json"
    else
        conf="/storage/.config/ext_only_hyperion.config.json"
fi
# debug
echo "$source_t1 (T1) - $source_t2 (T2) -> $conf"


# Scenario 1 - We run this script for the very first time, so $source_t1 is empty
if [ "$source_t1" == "" ]; then
    if [ `pidof hyperiond` > "0" ]; then
        killall hyperiond 2>/dev/null #killall because fresh start (empty $source_t1)
    fi
    /storage/hyperion/bin/hyperiond.sh $conf > /storage/logfiles/hyperion.log 2>&1 &
fi


# Scenario 2 - We've run this before, so there exist $source_t1 and $source_t2
# Scenario 2a - hdmi source did not change
if [ "$source_t1" == "$source_t2" ]; then
    if [ `pidof hyperiond` > "0" ]; then # Hyperion already started, so no need to turn LEDs on, which would cause interruption for each check!
# debug
        echo "Hyperion: ON"
        echo "Source T1 matches Source T2 - EXIT"
        exit 0 # nothing to do
    else # Hyperion NOT startet, so we need to turn it on with profile matching hdmi source
        /storage/hyperion/bin/hyperiond.sh $conf > /storage/logfiles/hyperion.log 2>&1 &
# debug
        echo "Hyperion: was OFF, I turned ON"        
    fi
fi
# Scenario 2b - hdmi source did change
if [ ! "$source_t1" == "$source_t2" ]; then
    if [ `pidof hyperiond` > "0" ]; then
        killall hyperiond 2>/dev/null
    fi
    /storage/hyperion/bin/hyperiond.sh $conf > /storage/logfiles/hyperion.log 2>&1 &
fi

The "daemon" (because of LibreELECS r/o filesystem plus missing (?) cron):
Name: h-grabber-daemon

Code

#!/usr/bin/env bash
# This script runs script 'which-h-grabber' in an interval
path="/storage/MyHyperionDaemon/which-h-grabber"
while [ 1 = 1 ]
    do
    bash $path
    sleep 5
done
exit 0

Of course, since I execute the "daemon" in an SSH session, I start it like this

Code

nohup bash h-grabber-daemon > /dev/null &

to disown the process.

Need a little help with custom remote xml
