Segment stitching
LiveBarn returns 30-min recording chunks. The player advances automatically on `ended`, and falls back to the next segment when a URL hits its 30-min expiry.
Pick a date and time window — the player stitches 30-minute recording segments into a single continuous timeline.
Presets match watch.livebarn.com URLs. Times use the same local slot grid as the picker (off-grid times snap to the nearest half hour).
LiveBarn returns 30-min recording chunks. The player advances automatically on `ended`, and falls back to the next segment when a URL hits its 30-min expiry.
Pass `resumeAtSeconds` (cumulative across segments) to `useLiveBarnVod` and the hook jumps to the right segment + offset on first play.
The hook auto-refreshes the playlist 5 minutes before the earliest URL expiry. No mid-watch 410s.
