OK, basically copy whats in SRC to your home drive using win-scp (though im sure there are many ways) then use sudo mv /home/osmc/src /opt/vc/ to move the files.
Got it installed for me; but its not running at start up;
if [ "x${SSH_TTY}" = "x" ]; then
/home/osmc/RPiPlay/build/rpiplay -n Bedroom -b auto -a hdmi # Or wherever the rpiplay binary is located
fi
./rpiplay works, but startup does not. Is there another way to run it?
