Emby Server - Option to ignore embedded thumbnail on library scan

[emby1234 1]

If a video file has an embedded thumbnail, Emby will use this instead of fetching images from the online sources or running the screen grabber.

 

I'd like an option to ignore the embedded thumbnail and always run the fetcher on library scan.

yes to this... cough rarbg cough cough

This is not true. Online sources always take priority.

This is not true. Online sources always take priority.

I haven't actually looked at your implementation, but that doesn't seem to be the case in my experience. Embedded thumbnails when present (at least for TV episodes) consistently take priority over online images, even though the latter are available.

[Luke 42081]

Most likely what is happening is the internet providers are not finding any images, and then it moves onto the screen grabber provider. screen grabber will use embedded thumbnails when available

If you can please discuss a specific example then we'll be happy to tell you exactly what happened. Thanks !

Not sure why this was moved to the general forum since it still is a feature request, but alright. It'd be nice to have an option to make the screen grabber ignore embedded thumbnails and always generate its own.

 

As for examples, what MrWebsmith mentioned provides some good ones, see the following excerpt from mkvinfo:

My image fetcher settings for TV episodes are set to the default, meaning the order goes as follows: TheTVDB -> The Open Movie Database -> Screen Grabber.

 

Regardless of this, a squashed version of the Matroska file's attached cover.jpg is used every time, even if I verify that an image is available from either or both of the sources at the time of the library scan.

This wouldn't be a feature request if image priority is not working properly.

 

Could you replicate the issue and post a server log.

 

How to Report a Problem

I'm assuming you'd want a debug log, then? There wasn't much of interest to see in the log I got without that checkbox toggled so I'd have to reproduce it later.

 

There's one thing I've neglected to mention so far so I'm throwing it out there now: when I add episodes to my server, I use scripts to call for a per-show refresh rather than a full library scan in Emby (i.e. http://server-address:8096/emby/Library/Series/Updated?tvdbid=***). Does this somehow make the import process behave differently?

 

 

Either way, this is still a feature request in that I wish for an option to disable the screen grabber's use of embedded images and have it always generate thumbnails itself when called upon.

A library scan would not modify your images.  You would have to do a full refresh (replacing images).

[emby1234 1]

That's not what I was saying.

 

When I was testing I copied a Matroska file that had attached images, gave it a different name matching a TV episode that aired weeks ago that definitely did have online images available, and then triggered a show update/refresh to quickly pick up on the new file being available instead of waiting 5-10 minutes for a full library scan. Emby imported it using the embedded cover.jpg. This should be easy to reproduce.

[Luke 42081]

@@emby1234, actually it's not easy to reproduce, because by default the screen grabber is the lowest priority image fetcher. The online sources are always higher. I do not see the behavior you are describing. Either you changed the image priority to make the screen grabber the highest priority fetcher, or something else is going on. Please try adding a new episode, and if the issue persists, please attach the Emby Server log from that time frame. You can learn how to do that here:

Thanks !

Just run it through mkvtoolnix.  The GUI makes it very easy and painless.  Uncheck everything you want to strip.

The mkvtoolnix package contains a stand alone tool for something like this.

 

I pass files through this one line .bat file to strip them off:

mkvpropedit %1 --delete-attachment "1" --delete-attachment "2" --delete-attachment "3" --delete-attachment "4"

 

Bam - No more, uh, coughing
