I just want to generate the thumbnail previews (.bif)

[ecrispy 38]

I have a library with custom media for which I wrote my own nfo/added images. Now I want to just generate the bif files. Is there possibly some cmdline tool for this? Does Emby use this - https://developer.roku.com/docs/developer-program/media-playback/trick-mode/bif-file-creation.md?

Or can I turn off generating nfo/downloading thumbnails? Will Emby by default NOT generate nfo/image metadata if it finds compatible ones in the media folder?

Hi, there's no command line option. We use ffmpeg to create the images, and our own code to write the bif files.

You can turn off anything you don't want in your server library settings.

You just enable the option per library to generate 10s interval images instead of Chapter images.

Just want to make sure existing metadata is not recreated and is read. Guess I'll do a test, thanks.

The easiest thing to do is to use the Scheduled task "Thumbnail image extraction"

It can be run manually by pressing the arrow at the far right of the text. whenever you wish and it will scan your entire library and only create bif files if they are missing and if the library's setting allows that.
