SOLVED: FFmpeg exits with code 187 when playing select files

[stewey]

Since you are not running the container as root, you need to pass in the render group.

Code:

getent group render | cut -d: -f3

Code:

    group_add:
      - "122" # Change this to match your "render" host group id and remove this comment

How do I do this on a Synology with DSM 7.2.2?  

I ran

Code:

getent group render | cut -d: -f3

and got

Code:

-sh: getent: command not found

Thanks!

Thanks for the link.  If I setup the container to run as root, as the decribed in that guide, the transcoding error I had goes away. 

I'm brand new to docker & NAS in general and noticed some of the guides I've seen suggest running containers as a limited user, I guess for security benefits?  So that's what I assumed was 'better', and I thought I'd try that first.  That lead to the transcoding error, ffmpeg exit code 187 I ran into.  Googling that & jellyfin eventually brought me here.

Reading through this thread, your post I quoted helped the OP get transcoding working while running the container as non-root.  So I tried running the same command to get the group ID I need to add to get transcoding working, and I got the error I noted. 

So wondering how to run that command/get the needed group ID info on a Synology.  

Thanks again!
