📝 Walkthrough

Walkthrough

The registry now targets Shaka Player 5.2.7. Caption state synchronization uses track selection and centralized player-state updates. Player and error-screen logic no longer requires runtime Shaka imports.

Changes

Shaka Player upgrade

Layer / File(s) Summary
Dependency constraints and guidance
apps/www/registry/collection/registry-*.ts, prompts/*.md
Registry blocks, hooks, UI items, and prompt examples now specify shaka-player@^5.2.7.
Caption track state synchronization
apps/www/registry/default/hooks/use-captions.ts
Caption toggling selects or deselects text tracks. syncTextTrackState updates the active track, available tracks, and visibility from player state.
Runtime-independent Shaka error handling
apps/www/registry/default/hooks/use-player.ts, apps/www/registry/default/ui/error-screen.tsx
The player hook uses a local load-interrupted code. The error screen uses structural error checks without a runtime Shaka import.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to 7dd1c

The captions hook can synchronize tracks from an old player instance after replacement, which may leave users seeing stale caption state. This bounded correctness risk should be fixed or explicitly accepted before merging.

In `@apps/www/registry/default/hooks/use-captions.ts`:
- Around line 99-112: The syncTextTrackState event handler currently uses the
render-scoped player and can apply stale tracks after player replacement. Read
the current player instance lazily through the applicable media API getState()
call inside syncTextTrackState, then use that instance for track lookup while
preserving the existing captions state updates.

In `@apps/www/registry/default/hooks/use-player.ts`:
- Around line 3-5: Configure the `@limeplay` registry namespace in components.json
with the registry URL pattern https://limeplay.winoffrg.dev/r/{name}.json so
both use-player and error-screen can be resolved by shadcn commands; the
affected sites are apps/www/registry/default/hooks/use-player.ts lines 3-5 and
apps/www/registry/default/ui/error-screen.tsx lines 191-194, which require no
direct changes.
