Preview Image Extraction failing

[hainter 1]

Hey All,

 

Having an issue where where the preview image extraction is failing for Home videos and photos library.  This was working on a previous version of Emby and stopped after upgrading to 4.7.5

 

 

I am running Emby in a docker in an Unraid server.

 

The video preview thumbnails and the chapter thumbnails are working...its just the preview thumbnail that shows when you are browsing thru your library.  This used to automatically take a preview thumbnail at like 20% into the movie and display it on the home screen.

 

 

I suspect some kind of permissions issue but I haven't been able to track it down and could use some help.

 

 

Here is a sample of the log where the extract-imageseries works and then the quick-extract-image fails

Hi there @hainter please attach the complete emby server log file. Thanks.

[hainter 1]

I would rather not, can I PM it?

[Luke 42078]

Yes you can.

[hainter 1]

I have messaged the log

Thanks. @softworkz will take a look.

[Luke 42078]

@hainter

Can you provide a copy of this video file for testing? Thanks.

[hainter 1]

will message

 

 

Thanks

[hainter 1]

Any thoughts on this? I haven't had any luck getting it to work.   Like I said the chapter thumbnails and the scrubbing thumbnails work fine, just don't have a preview thumbnail on the main page.

Hi there, have you updated to Emby Server 4.7.6? Try doing that and then refreshing the metadata on affected titles. Please let us know if this helps. Thanks.

[hainter 1]

 

hi.

 

 

4.7.6 did not fix the issue.  Will continue looking.

 

 

Thanks

 

 

 

 

[mshaf 1]

I have the same issue and I am currently running 4.7.6

 

@hainter

Did you ever resolve this?

[hainter 1]

its still not working in 4.7.6.   Like I said not sure if its a permissions issue on my end or something with the Emby.  

 

 

It was working fine in an older version of the Emby.

 

 

 

 

 

 

[hainter 1]

Ok,  this is working now and just for the record wanted to record the solution.

 

I was using the binhex/arch-emby docker in Unraid.

 

They made an update 3 days ago that seems to have fixed the issue, see screenshot for what it was...I don't fully understand this but I know it has something to do with making the docker use Emby's version of ffmpeg.

 

 

 

 

 

 

 

 

[Luke 42078]

That's good news. Thanks for the feedback.

@mshaf does this help?

[mshaf 1]

Thanks - I noticed that they made the update.

I've since moved to the official emby docker version which resolved my issues. 

[Luke 42078]

Thanks for the feedback.
