on my system, it depends on java-openjfx (and mplayer if you want to record streams).
the way i see it, you could just unzip the program into /opt, and use this to start it:
Code:
cat /usr/bin/mediathek
#!/bin/sh
if [ -d "/usr/lib/jvm/java-8-jdk" ]; then
export PATH=/usr/lib/jvm/java-8-jdk/jre/bin/:$PATH
elif [ -d "/usr/lib/jvm/java-8-jre" ]; then
export PATH=/usr/lib/jvm/java-8-jre/jre/bin/:$PATH
else
export PATH=/usr/lib/jvm/java-8-openjdk/jre/bin/:$PATH
fi
cd /opt/mediathek
java -jar MediathekView.jar $*
of course i'm simplifying things; you should definitely follow the instructions provided.
you can also use this directly from your browser:
https://mediathekview.de - no installation required.
