iina-lastfm

mpv script to scrobble songs played through iina to last.fm, since nobody else has made one.

No dependencies! Runs on macOS Big Sur(+) with just iina installed.

Last tested on iina 1.3.5 & macOS Ventura 13.5.

You could probably get this working for mpv on other operating systems.

Installing

1. In iina advanced preferences, enable advanced mode, and set the config directory to ~/.config/mpv/

2. In iina advanced preferences, enable:

   Name	Value
   load-scripts	yes
   input-ipc-server	/tmp/mpv-socket

3. Copy the lastfmscrobbler folder and the scripts folder into ~/.config/mpv/

4. Open lastfmscrobbler/scrobble.sh and modify the USERNAME variable:

USERNAME='lastfmUsername'

5. In a terminal, write your last.fm password to the login keychain, under the com.iina.lastfm service:

security add-generic-password -a "lastfmUsername" -s "com.iina.lastfm" -w "mypassword"

Debugging

With iina open and playing a track, run scrobble.sh directly and check the error.

/usr/bin/env bash ~/.config/mpv/lastfmscrobbler/scrobble.sh

The script won't work unless the track you're playing has both of these metadata tags.

'TITLE'|'Title'|'title'

'ARTIST'|'Artist'|'artist'

You can see the raw metadata of the track when iina is running with

echo '{ "command": ["get_property", "metadata"] }' | nc -U /tmp/mpv-socket

If the program is scrobbling when you run scrobble.sh manually but not automatically, check iina.log for lua errors.
