Modifying input.config doesn't seem to matter.

[epistularum]

I've downloaded the standard mpv input.cong and edited a line to have a 2s seek instead of 5s.
I can confirm it works with a regular mpv install but modifying plex-mpv-shim's mpv.conf with the exact same parameters doesn't affect at all plex-mpv-shim's behaviour.

That's because I override the seek buttons to also allow menu navigation. I'm in the process of reworking the override shortcuts to be configurable. I'll add configuration options for the seek time too.

Glad to see you're already on top of the issue!

This change has been applied to master and will be in the next release.

Should I open the same issue for jellyfin-mpv-shim?

[iwalton3]

No need, it already has a pending fix: jellyfin/jellyfin-mpv-shim@f897b67

[iwalton3]

The fix for this is in the latest version.
