Thanks!

I realize this is closed and if you prefer me to go to dietpi forums I can but when I enter my mpg codec (I don't have a wvc1), I still get "codec disabled" when running the "vcgencmd codec_enabled MPG2" command. I triple checked with raspberrypi.com to make sure I have them the right serial and they said yes. Any thoughts on what might be the issue? The ramdisk DietPi/Config.txt definitely has the serial in it.

@pzman89

Thanks for the report 👍

I'll reopen this ticket and see if we can replicate.

For me the WVC1 seems disabled in Movian (self compiled) MPEG2 does work.

[pzman89]

I was thinking of running a fresh copy of dietpi to see if it gets resolved but let me know if theres something you want me to check before trying.

[pzman89]

@Fourdee still a no go after a fresh DietPi install. It doesn't even save my key through the interface, I have to manually enter it in /Dietpi/config.txt. Even then, it still reports disabled.

Thanks, i'll try to replicate.

If its still reporting disabled, might be an issue with current kernel (4.9). I'll check with 4.4.

• Ok, possible bug with adding the entries, not generating the required line in config.txt. I'll get that fixed.
• Updated RPi kernel/firmware through apt, currently 4.9, same issue with status disabled.

@Fourdee You might be right about the kernel. I installed raspbian, which has kernel 4.4.50 and added the key via config editor in NOOBS and its reporting as enabled.

You beat me to it 👍 just installed Jessie lite to run the same tests lol. I'll see if I can confirm.

Raspian lite:

• 🈯️ 4.4.50-v7+
• 🈯️ apt-get upgrade = 4.9.24-v7+
• 🈯️ Install DietPi Kernel

Strange.
