MPEG2 and VC-1 licenses not required

yoyoma2 · September 4, 2018 at 7:11 PM

Just migrated from openelec after an SD card hardware failure in my rpi2. Noticed that the licenses seem to do nothing. Booting with or without my licenses in the config.txt the same result is produced by the following:

Code

LibreELEC:~ # vcgencmd codec_enabled MPG2;vcgencmd codec_enabled WVC1
MPG2=enabled
WVC1=enabled

Also the wiki page explaining how to check the license status is missing a newline in between vcgencmd commands.

Congrats on a nice looking evolution of openelec.

The license info is saved to a built-in eeprom (OTP memory) in broadcom SoC.

I always thought that the lack of an eeprom was the reason for the need of a config.txt file. Just noticed this about MPG2 patent expiry?

Once the license keys are saved to an OTP memory they can be removed from config.txt.

You can check your license keys with this command:

Code

vcgencmd otp_dump | grep -E 45:\|46:

Cool command thanks. The wiki has an error as mentioned in my OP.

Marking thread as resolved.
