Transcoding FFmpeg error 218

[TheDreadPirate]

For this ffmpeg log, it is using AV1 which doesn't have a low power mode. So that isn't a factor, I think.

But, to eliminate firmware as a factor, we should ensure they are installed.

Code:

sudo apt list --installed | grep firmware-linux-nonfree

If that returns no packages, you will need to add "non-free" and "non-free-firmware" to your apt config for Debian's repos..
