Skip intro and credits
Reelhost installs Jellyfin's Chapter Segments Provider and turns it on for your TV libraries. The Skip intro button then appears for episodes whose chapters are named like "Intro" or "Opening", which files from discs and many releases have. Episodes without chapter markers get no button.
Intro Skipper is optional and only added if you tick it. It finds intros by listening to each season, so it works without chapter markers. It's a community add-on, made by volunteers rather than by Jellyfin or Reelhost, and it comes from its own source (intro-skipper.org), which Reelhost adds to Jellyfin. Reelhost first checks that it has a version for your Jellyfin; if not, it adds nothing and says so.
When it's added, Reelhost sets Intro Skipper up to find end credits too, so a Skip credits button appears as well, and to scan new episodes every night.
