The captions context menu on tvOS was always empty because it relied on
an .onAppear callback that was never triggered. The captionsPicker view
with .onAppear was only rendered on iOS/macOS, not tvOS.
Changes:
- Access captions directly from player.currentVideo?.captions instead of
using a state variable populated via .onAppear
- Fix label logic to show "Disabled" when captions are available but not
selected, and "Not available" only when video has no captions
- Remove unused state variables and helper functions
This commit addresses crashes caused by race conditions when accessing audio track arrays:
- MPVBackend.swift: Use safe index clamping to prevent array out of bounds crashes when selecting audio tracks
- PlayerModel.swift: Add selectedAudioTrack computed property for thread-safe audio track access
- ControlsOverlay.swift: Use safe accessor with "Original" fallback label
- PlaybackSettings.swift: Use safe accessor with "Original" fallback label
This fix resolves approximately 37% of crashes (23 out of 62 crash logs) that were caused by index out of range errors in MPVBackend.playStream at line 345.
- fix subtitle disabling not working
- make subtitle adding/removing async
- make subtitle menu non blocking
