YT Player Admin

API tokens

Tokens let scripts write shared lyrics and chapters (Authorization: Bearer …). The token is shown once — store it in your secrets vault.

Inject lyrics from captions

Reads the video's YouTube captions (human subtitles first, else auto captions in the spoken language) and saves them as the shared lyrics.

Play the song here and time every line against it: Set stamps the playhead onto a line, Tap mode walks down the lines as you tap (Space), and the waveform scrubs. Saving writes a new shared revision — the old one stays restorable below.

Upload video / audio

Uploads are served by this server and appear in search and in the app's 📁 Library. Title, artist, duration, cover art and embedded lyrics are read from the file; a separate cover image and manual title/artist override them.

Every save is kept as a revision. Restoring writes the old version back as a new revision, so nothing is ever lost. A JSON backup of all notes is also written daily to /app/data/backups.
