A high-performance Lua script for the mpv media player that generates on-the-fly seekbar thumbnails without background CPU usage. It acts as a backend that UI scripts like uosc or ModernX call to display preview thumbnails when hovering over the timeline.

Use cases

  • show video preview thumbnails when hovering over the mpv seekbar
  • add timeline thumbnail previews to a custom mpv UI script
  • generate thumbnails on demand without background thumbnail generation hogging CPU
  • preview YouTube and web videos in mpv while scrubbing the timeline
  • use thumbnail previews with mpv frontends like mpv.net or ImPlay

When to choose

  • you use mpv and want seekbar thumbnail previews with no dependencies and minimal CPU overhead
  • you maintain or use a custom mpv UI (uosc, ModernX, progressbar, etc.) and want to integrate thumbnail support
  • you need thumbnails that respect applied video filters and mixed aspect ratio videos

When to avoid

  • you want a standalone thumbnail generator or a GUI that displays thumbnails on its own - this script requires a separate UI script to render them
  • you do not use mpv or an mpv-based frontend
  • you need pre-generated thumbnail galleries or background thumbnail caching
