MythTV Official Community Forum

I finally got around to testing my instructions since mythtv-light moved to Orangedox. This was a quick edit after I got my RPI4 mythtv combo setup for this years RVing season. (My RV is where I use the RPI4 with mythtv)

I had trouble with the script run_mythfrontend.sh from pi-utils and not the skills to fix it so I found a solution that works fine on my RPI4 combo FE/BE.

I had trouble with the script run_mythfrontend.sh from pi-utils and not the skills to fix it so I found a solution that works fine on my RPI4 combo FE/BE.

Code: Select all

#!/bin/bash

# script to run mythfrontend from version 31 on Raspberry Pi under Raspian Buster using EGLFS
# can be added to .bashrc to allow autostart of mythfrontend on boot

#check for any arguments on command line, if so use for mythfrontend command, so we can use different parameters
#e.g. run_mythfrontend.sh --logpath /home/pi --loglevel debug
# if no arguments set --logpath /tmp
if [ -z "$*" ] ; then
	ARGUMENTS="--logpath /tmp -O PowerOffTVOnExit=0"
else
	ARGUMENTS="$*"
fi

# set perfomance mode, not sure if needed for Pi4, do it anyway
echo performance | sudo tee /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor


RESOLUTION="1920x1080@60"

echo "Setting screen to $RESOLUTION"


#for QT debug add to command line QT_QPA_EGLFS_DEBUG=1 QT_LOGGING_RULES=qt.qpa.*=true
QT_QPA_EGLFS_ALWAYS_SET_MODE="1" QT_QPA_PLATFORM=eglfs mythfrontend $ARGUMENTS
# fixup keyboard after exit from mythfrontend, bug in QT causes segment fault which kills keyboard input
kbd_mode -u
# restore cursor
setterm  --cursor on

exit 0

NOTE! I seem to only need this if I overclock the RPI4
