The Raspberry Pi is different in many things compared to a normal computer. A normal PC has a BIOS where all system configurations can be set. Therefore the RPi uses a file called ‘config.txt.
As LibreELEC’s system is generally a read-only system by default, you will need to get those write-permissions first:
mount -o remount,rw /flash nano /flash/config.txt // Replace the '00000000' values with the keys you received after your purchase decode_MPG2=0x00000000 decode_WVC1=0x00000000 After edit: mount -o remount,ro /flash // Checking the license vcgencmd codec_enabled MPG2 vcgencmd codec_enabled WVC1
