lolque 0 Posted August 5, 2022 Share Posted August 5, 2022 Emby 4.7.6.0 using official Docker image. The default image fetcher setting is to only download 1 backdrop per series. I increased this limit to 3 backdrops (for variety), however during the next metadata scan, Emby re-downloaded the same backdrop that it had downloaded previously, leading to duplicates across all my series. Separately, Emby names the backdrop differently when you do a metadata scan vs initial import. Link to comment Share on other sites More sharing options...
pwhodges 1522 Posted August 5, 2022 Share Posted August 5, 2022 If you have more than one image source (and maybe even with a single source) it is common to have multiple images which are visually identical - but Emby has no way to know that. For instance, here are the backdrops I see for the series you illustrate: Your best bet to avoid duplicates is probably to select only a single source of images.

lolque 0 Posted August 5, 2022 Author Share Posted August 5, 2022 I only have one image source (TVDB) and there aren't any duplicate images on TVDB for this series. This is consistently reproducible if you set the amount of backdrops to fetch to 1, import a new series, set backdrops to 3, refresh metadata.

ebr 14902 Posted August 5, 2022 Share Posted August 5, 2022 Hi. Your image is showing what actually exists on your server. Can you please show the same search dialog that PW did? Link to comment Share on other sites More sharing options...

ebr 14902 Posted August 6, 2022 Share Posted August 6, 2022 If you look in the actual media folder, do you have one named "fanart.jpg" and then others named "backdrop1" "backdrop2" etc? Or, possibly, this is related to you NOT having the save images with media option selected but you DO have a fanart.jpg alongside the media?

Happy2Play 8239 Posted August 6, 2022 Share Posted August 6, 2022 Yes there appears to be something going on here with these images as the information is different. But have not been able to reproduce image duplication unless images come from two provider sites. Link to comment Share on other sites More sharing options...
lolque 0 Posted August 7, 2022 Author Share Posted August 7, 2022 This is easily reproducible with the steps I provided. Here's a video using the official Docker container. All I did was create the following directory structure "/tmp/library/The Eccentric Family/Season 1" so that Emby would have something to fetch metadata for.

pünktchen 1251 Posted August 7, 2022 Share Posted August 7, 2022 The only bug i see is fanart vs. backdrop but not the duplicated images. How should Emby know what image was previously downloaded or provided by the user? 1 Link to comment Share on other sites More sharing options...

Hi. I see in your video that you do not have that option selected. Can you confirm whether or not there is a backdrop/fanart image alongside the item in the media folder?

How should Emby know what image was previously downloaded or provided by the user? We try to avoid it by looking at byte sizes. That's really the only way.

lolque 0 Posted August 7, 2022 Author Share Posted August 7, 2022 Can't emby store the image ID and source to reduce the chance of duplicates? Link to comment Share on other sites More sharing options...
Happy2Play 8239 Posted August 7, 2022 Share Posted August 7, 2022 Honestly do not know as I followed the exact same steps/settings from video on my Windows stable and beta servers and did not get duplicate images. Nothing with media Will assume a timing difference as I do not get this fanart/backdrop naming mismatch. Link to comment Share on other sites More sharing options...

Luke 36999 Posted August 25, 2022 Share Posted August 25, 2022 If download images in advance is unchecked, then you will be more likely to get duplicates. But of course if it is checked, you'll have longer library scans. Link to comment Share on other sites More sharing options...

I thought I kind of already spelled it out - there is no way for us to know for sure that a new image will be a duplicate. We do our best to make a good guess by looking at file sizes in bytes. Generally this works pretty well as long as you only have one image fetcher enabled. Link to comment Share on other sites More sharing options...
lolque 0 Posted August 25, 2022 Author Share Posted August 25, 2022 Right, but in the video I posted, there is only one image fetcher and is reproducible consistently. Link to comment Share on other sites More sharing options...
Luke 36999 Posted August 25, 2022 Share Posted August 25, 2022 OK then you may want to play with the tradeoff of downloading images in advance. Link to comment Share on other sites More sharing options...
