If you wish for your server to try and find subtitles for you automatically, you’ll need to enable and configure the “OpenSubtitles” source for your library’s metadata agent (e.g. enable it for the “Plex Movie” agent, used on your Movie library).
However, this option appears to only be available on the “Plex Movie (Legacy)” agent, and then only via the Settings > Agents interface.
Does this Help page need to be configured, or am I just missing the feature in the UI?
So the new agent does not have the ability to download subtitles? I don’t use this feature, but I saw a question about it earlier, which led me to look at the help page.
Actually the key word is “automatically”. The legacy agent was able automatically download subs from opensubtitles. The new agent only allows you to manually download subs.
That’s kind of a weird way of looking at it. The new agent doesn’t download subtitles at all, manually or automatically – it just uses subtitle files that you must get yourself, by other means.
I can pause any movie/show I am watching, select the subtitle button, and click on More. This submits a subtitle search to opensubs using the filename as a search term. If I select one, it downloads and enables.
(Currently seems to be a bug on android players where it skips to the end of file instantly. On shows, it brings up the Play Next countdown. I need to back up and resume the file, but the subtitle is downloaded and enabled.)
So, there is a manual way to DL subtitles within Plex, but it is unintuitively hidden. You have to start playing a show before you can get the subtitles? That’s nuts. If that’s going to remain the only way to do this, than this too should be made clear in the Help page.
