Seeing errors on the Image extraction process.

[OurfamilySpot 5]

Help, I am seeing a lot of these suddenly.    I noticed that after I chose to rebuild metadata and replace images I lost a lot of the prior images.  I checked the server log and see the following.  I don't know what I am looking at but it seems consistent.  

I see an error showing (output file not found), but I don't know how that would even be possible?   My entire media library is on one volume and images are able to be generated for other files without issue.  There are NO special characters in these file names and there are NO permissions on the drive.

Hi there, please attach the complete emby server log file. thanks.

[OurfamilySpot 5]

so, this seemed to clear itself up without me doing anything.   I don't know what caused it, but its working perfectly now.

Hi, my guess would be that it's related to certain video files. The server won't keep trying over and over again so that could be why those errors are gone from your log now.
