Amcrest AD110 Ring Dorbell FFMPEG Befehl

Hello, my dears,
when I’m in the console in the Home Assistant I can’t run the “ffmpeg” command. Will not be found. Just a command with underscore “_ffmpeg”. If I run this I get the following message: “_arguments: comparguments: 327. can only called from completion functions” Do I have to install anything else?

Greetings from Stefan Harbich

Hello,
the solution was ffmpeg in the docker container above

apk add ffmpeg

to install.
