Thumbnails not generating

[mshaf 1]

Hi,

I am running a docker instance of Emby server on unraid and recently started getting issues after upgrading the container. I am currently running 4.7.6.0

No thumbnails are working, nothing is now shown on the library icon or the chapters.

I see the following errors in the logs.

*** Error Report ***

This command fails

 /usr/bin/ffmpeg -skip_list 15 -f matroska -threads 1 -copyts -i file:"/media/plex/movies/[movie]/[movie].mkv" -an -sn -update 1 -vf "scale=trunc(min(max(iw\,ih*dar)\,min(600\,0*dar))/2)*2:trunc(min(max(iw/dar\,ih)\,min(600/dar\,0))/2)*2" -vsync 0 -f image2 "/config/cache/temp/bf4db904-3f43-4b32-8af6-0ec606871dfb.jpg"

 

when running the above command inside the docker container, I get the following error message

Unrecognized option 'skip_list'.
Error splitting the argument list: Option not found

 

If I remove the skip_list argument then ffmpeg starts to do its work on the command line.

 

I would appreciate some help.

 

Thanks.

HI, how did you install Emby Server?

Hi, 

Thanks for the quick reply,

I am using unraid and the docker version of Emby Server.

Edit:

This has been working perfectly, it's just the latest update has caused some issues.

Are you sure that's our official docker container?

https://emby.media/docker-server.html

That doesn't look like it. Can you please attach the complete emby server log?

Sorry, it's the binhex-emby version - isn't that based on the official version?

Yes but it appears to be missing essential components such as our custom ffmpeg build. That's the reason for the errors.

Brill - I'll use the official version and report back. 

Thanks for your help @Luke
