Duplicate Backdrops

It can also help to set your minimum backdrop bandwidth width to 1980.  Often times I'll find there is a backdrop that exists in 1920X1080 and 1280X720 with the same image.

 

Worth noting that this problem will impact absolutely any media player app that supports backdrops and downloads from more than one source.  It's not as if fanart.tv is going to police their image sets to remove things that also exist on themoviedb.com.

Yup, no perfect answer here. Doing our best, but the options are always there to tinker with.

Thanks for the fast replies. Sorry I didn't catch that the approach had changed.  I know there is no perfect answer here. Filtering by size is problematic because many backdrops look exactly the same but have different sizes. I'll monitor things based on the new algorithm, and if I think it is not doing as now described, I will post a log. It might be good to change the comments in the metadata image setting to match the revised approach.

 

Thanks again for your help, and of course, thank you for this amazing product and the effort you put into it. I honestly can't imagine how you produce so many improvements so quickly.

I am running Server version 3.0.5192.19560. It clearly says no backdrops will be downloaded if an entry already has any backdrops. That is not what is happening. I have repeatedly wasted lots of time cleaning out duplicate backdrops, and new ones just keep appearing. Why is this happening? I am not running any other software that downloads metadata of any kind. I would really like to get the software to work the way it says it does before I clean up yet again.

 

Thanks

Can you post your server log?

Also, this was amended - it will not download duplicate backdrops based on file size in bytes. that is the new algorithm for determining duplicates.

 

What you might want to try is picking only one source for images using the metadata configuration area. for example, it is sometimes difficult to filter out duplicates from fanart / the movie db.

It would be pretty awesome to leverage Haar Wavelets to identify/flag potential dupes.  I found a couple examples of C# code of the algorithm, and supposedly it's not too compute-intense (papers seem to indicate it's a p-time problem). Wimpy smartphone and camera SOCs have been leveraging it for face detection for quite some time, and it works fairly well at image comparison even if there's been mild transformations (cropping and proportionate scaling).

Other option is to just lock the meta data after you are happy with what you got..
