wtf is plex-intro-uploader?

Plex Intro Uploader is a self hosted tool for people who run their own Plex media server. Plex already scans TV episodes and detects where the intro or opening credits start and end, but that information usually stays locked inside your own server. This tool finds every episode where Plex already detected an intro, matches those episodes to IMDB using data from TMDB, and lets you review the results and submit them in bulk to IntroDB, a shared community database of intro timestamps used by other apps like Nuvio, Infuse, and Jellyfin. It runs as a Docker container with a simple web interface. Setup requires a Plex Media Server that has already scanned for intro markers, a free API key from TMDB, and a free API key from IntroDB. Once running, you enter your Plex server address and token, your TMDB and IntroDB keys, and the exact name of your TV library inside the app's settings page, and these are saved so you do not need to re-enter them after restarts or updates. To use it, you click Scan to have the tool look through your Plex library and resolve episodes to their IMDB IDs, then review the results table where you can select entries by show, season, or individual episode. Clicking Submit Selected sends the chosen entries to IntroDB, automatically slowing down and retrying if it hits rate limits, with live progress shown as it works. A Retry Failed button lets you resubmit anything that failed or was rate limited earlier.
