Same behaviour as the release server version. Errors are the same.

So still getting the 1 minute timeout on the ffmpeg peocess for image extraction?

Yes I believe so.

See attached log extract 

As I said before, the FFMPEG method Emby server is using to extract a single thumbnail from a video file is prone to issues.

And, I suggested alternative method that is much quicker and more likely to work with any problem some videos.

Yes it is the same on the 4.9.0.30 beta as before

1 minute timeout on both methods used by Emby Server to extract an image

Yes - this was referred to the development team - together with the earlier evidence which is the same as in the beta

Was this issue resolved?

I have the same problem on 4.8.8.0. Some thumbs are generated for certain videos in the same folder as some just don't.

I think you said that back in Aug 2024.

I had already suggested a fix in July 2024.

So what are "we" actually looking at ?

[Luke 42077]

The problem is in the ffmpeg build, so we are looking into that. Thanks.

[Happy2Play 9780]

I guess this topic should be tagged with the platforms it affects as I still don't see this issue.

[sa2000 674]

It is to do with slow systems and specific videos that invoke the bug in image extraction - not platform specific but seen a lot on NAS

The fix I suggested works with the FFMPEG that emby uses. That's how I tested it in addition to newer version.

So the quick fix is to change emby not FFMPEG.

[Luke 42077]

Hi, we have this resolved now. If you need immediate relief, the fix will be in the beta channel in the next build build, which will be 4.9.0.42+. Thanks !

Thank you. Will check it out

[macnb 32]

I can confirm that 4.9.0.42 beta fixes the issue for me. The test thumbnail video generated the correct thumbnail and others video folders too.

Also the speed of thumbnail generation seems somewhat faster.

Thanks

Interesting. We have not yet released the version of Emby ffmpeg that has the significant improvements to image extraction times

Whatever has been changed has made a difference. The key fix is that the beta Emby now extracts the thumbnails from those troublesome videos.

The speed of extraction may be subjective as I said it "seems" faster but it could have been my perception.

Nope, same here.
