kodi播放音乐时禁止隐藏播放信息（黑屏）

Add this to your advancedsettings.xml file:
<!-- Stop Music OSD from disappearing for 2 hours -->
<songinfoduration>7200</songinfoduration>

Found the location of the file -
LibreELEC:~ # find / -xdev -name advancedsettings.xml
/usr/share/kodi/system/advancedsettings.xml

Wrong file.
As the log says, that's a read-only file.
You'll need to make a new advancedsettings.xml and stick it in /storage/.kodi/userdata (or edit the one you've already put there).
