This is a plugin for stash. It adds a Find duplicate scenes task. This task processes the vtt sprite files in your stash library, performing a perceptual hash. Any scenes that it detects are output in the plugin log.

Optionally, it can tag duplicate scenes with a (existing) tag, and it can populate the details field of the duplicate scene with the ids of its duplicates.

Untar the release for your platform into your plugins stash directory and reload plugins (or restart stash). A new task should be present in the Tasks page.

A documented default configuration file is included.

NOTE: the plugin uses the sprite files to find duplicates. This means that if you remove a file from your stash library but do not remove the generated files (specifically the generated sprite file), then the plugin will continue to use the sprite file for duplicate detection.

make build - builds the plugin executable for your platform make build-release-docker - performs cross compilation in the stashapp/compiler:develop docker image and builds release tars

Command-line mode can be run by providing the sprite directory as a command line parameter. In this mode, it outputs a duplicates.csv file containing matching checksums with the match score. It is intended for debugging and fine-tuning the sensitivity. The execution can be stopped safely by touching a .stop file in the cwd.
