The HKSV recording was failing because:
1. The dataSend.data message structure was wrong - `packets` was a flat integer
instead of an array of objects with `data` and `metadata` fields matching
the HAP-NodeJS specification
2. Each video/audio frame was sent as a separate mediaFragment, but Home Hub
expects GOP-based fragments (~2-4 seconds of accumulated data)
3. Large fragments were not chunked (max 256 KiB per chunk)
Changes:
- Fix HDS dataSend.data message structure to use proper packets array with
nested data/metadata (dataType, dataSequenceNumber, dataChunkSequenceNumber,
isLastDataChunk, dataTotalSize)
- Add 256 KiB chunking for large media fragments
- Buffer moof+mdat pairs in hksvConsumer and flush on keyframe boundaries
(GOP-based fragmentation)
- Pre-start consumer at pair-verify for instant init segment delivery
- Add write-response support to HAP PUT handler for ch131 DataStream setup
- Fix HAP service linking to match HAP-NodeJS reference
- Add default SelectedCameraRecordingConfiguration (ch209) value
- Start continuous motion generator at pair-verify with dedup protection
- Introduced HKSV configuration options in homekit.go, allowing for motion detection and doorbell features.
- Implemented API endpoints for triggering motion detection and doorbell events.
- Enhanced server.go to handle HKSV sessions and manage motion detection states.
- Created new accessory types for HKSV and doorbell in accessory.go.
- Added support for audio recording configurations in ch207.go.
- Defined new services for motion detection and doorbell in services_hksv.go.
- Implemented opack encoding/decoding for HDS protocol in opack.go and protocol.go.
- Updated OpenAPI documentation to reflect new endpoints and features.
- Extended schema.json to include HKSV configuration options.
