I installed the dev motioneye by the dev wiki and when i got to the sudo motioneye_init I've got that error:

os: Volumio device: Raspberry pi

[coder0107git]

Run sudo apt install libavcodec58 libavdevice58 libavfilter7 libavformat58 libswresample3 and then rerun sudo motioneye_init.

Run sudo apt install libavcodec58 libavdevice58 libavfilter7 libavformat58 libswresample3 and then rerun sudo motioneye_init.

I ran it and it gave me that error:

Hmm those packages should have been installed with ffmpeg already. What does the following say?

apt policy libavcodec58
dpkg -l | grep libavcodec

Probably volumio has another conflicting version of the ffmpeg libraries installed?

dpkg -l | grep libavcodec
