macOS:
- Replace deprecated NSSavePanel.begin(completionHandler:) with async begin() API
- The old API has been deprecated since macOS 12 and may silently fail on macOS 26
- Added diagnostic logging throughout recording completion flow
iOS:
- Added diagnostic logging to track onRecordingSaved → pendingExportURL → sheet chain
- Logs file existence, size after recording completes
Diagnostic logging added to help verify the save dialog flow:
- macOS: file size check, showSaveDialog entry, NSSavePanel response
- iOS: recordStream output verification, onRecordingSaved call, sheet binding activation
Recording:
- stopRecording() now only sets stopRequested=true, no longer cancels task
- Task exits polling loop naturally → merges TS segments → exports MP4
- System share sheet + Photos save shown on completion
- Added HEAD request to detect HLS Content-Type for non-.m3u8 URLs
- Faster exit when stopRequested && segments exist
Playback:
- Copy imported files to app Documents sandbox (security-scoped URLs expire after defer)
- Remove Referer header that blocks some streams; use iPhone UA only
- AVURLAsset options only for http/https schemes
Media Library UI (iOS):
- Replace NavigationSplitView with VStack + horizontal category chips
- Search bar at top, swipe actions for queue/delete
- scrollDismissesKeyboard(.interactively) on list
- Tap gesture sends resignFirstResponder to dismiss keyboard
- Compact rows with context menu, inline play button
- Close button in navigation bar
- presentationDetents(.medium) for tag/playlist sheets
- Poll m3u8 every 2s to download new segments (supports live HLS)
- For non-HLS URLs, download entire file
- Accumulate TS segments incrementally, merge on stop
- Remux TS→MP4 via AVAssetExportSession
- Show system share sheet + save to Photos on completion
- Proper cancellation support via Task.cancel()
