Finds Japanese Adult Video (JAV) metadata for Plex from R18.dev, JavGuru, JavDatabase, 141JAV, and OneJav.
Click here to download a zip file containing the latest version of plugin, or click the green "Clone or download" button above. Extract the Jav18.bundle folder from the zip file (within the PlexJav18.bundle-master folder) and place it in your Plex server's plugins folder. You can find out where that is here. Close your Plex server and restart it, and it should be selectable as an agent (called "Jav18") in movie and video libraries.
It searches the supported databases using the release label and number associated with the video (e.g. XYZ-123). It gets this info from the filename, so ensure that your video files have it in their name. If the release is found, it then consults AV-Wiki.net to find the FANZA ID for that release, which is how titles are catalogued on R18. If there is none or R18 doesn't have it listed, then the other sites are used as a backup for metadata.
I use and have tested the following folder structure for my library:
JAV/
ABC/
ABC-123.mp4
ABC-456 - pt1.mp4
ABC-456 - pt2.mp4
XYZ/
...This is the only structure I've tested, but it shouldn't particularly matter as long as Plex can distinguish which files belong together and which don't.
None of the supported databases are 100% complete, so there may be some releases that won't have their full metadata. If no data can be found on R18.dev, JavDatabase is used as a backup. If that fails, then 141Jav and OneJav are used as a last resort, since they have most things listed but have minimal metadata.
JavLibrary seems to have the most complete database, but as of yet I haven't found a good way of scraping that website. JavGuru was good as well, but recently added bot protection.
Go to the Manage Library page for your Jav18 library and select Advanced. There are several options available. By default, only some are enabled, but if you're not getting any results, you can try to enable the others. Note: These settings only change which options show up when matching. When compiling metadata, all possible sites are checked.
R18 supports both English and Chinese, so you can pick which language you would like to use in the Manage Library settings. This only affects data scraped from R18.
With R18's demise, none of the supported databases provide metadata in any language besides English. Unfortunately, that means for now English is the only supported language.
Make sure that you are using the correct folder structure (see above) and that your videos are named for the release number (ABC-123.mp4). If your videos are named correctly and still aren't having metadata populated for them, make sure that you can find them on the sites listed at the top.
The API that generates the high-res poster doesn't have 100% up-time, so if you're getting a low-res poster, try waiting a a minute and trying again. After refreshing metadata, you might have to edit the title to manually select the newly generated poster.
If there isn't already an issue written up for your problem on the issues tab, write one up and attach your Jav18 plug-in log to the issue. Find the log folder using this support article. Once you are in the log folder, navigate into PMS Plugin Logs and grab the file called com.plexapp.agents.jav18.log.
You will need to find the R18.dev's unique content ID for your title (for example, '118abf009r' for 'ABF-009'). Then, in the plug-in settings, enable 'Use the Content ID instead of the DVD ID to search'. Fix your video's match and search for the content ID. It should update with metadata for the correct title now. While the 'Use the Content ID' option is enabled, only R18.dev will be able to provide metadata, so you should disable it once you are done disambiguating your video.
This plugin was based on PhoenixPlexCode's Data18-Phoenix.bundle plugin here.
