# Purpose {{{
|
||
# This script will try to control Kodi with kodi-send command
|
||
# 1. Start Kodi if not already running.
|
||
# 2. Send user command to Kodi running instance.
|
||
#
|
||
# In Kodi, pause|play|toggle = TOGGLE ! 😑
|
||
# So for a real PAUSE, some extra tests are required :
|
||
# * Request the API (with curl) to check if a playlist is active.
|
||
# * Request the API to get the media speed.
|
||
# * Exit if the media is already paused (speed = 0).
