Add trailing commas to the arguments passed to fallbackToSDLiveview in ui/src/pages/Dashboard/Dashboard.jsx. This is a non-functional formatting change applied to the WebRTC initialization, ICE candidate handling, and connection-state fallback calls to align with the project's code style/formatter.
Clean up trailing commas and minor formatting in ui/src/pages/Dashboard/Dashboard.jsx. Adjusts object/argument commas and formatting around WebRTC message handling, peer connection setup, error handling, and SD liveview fallback callbacks to avoid potential syntax/lint issues.
Apply consistent formatting to ui/src/pages/Dashboard/Dashboard.jsx by adding trailing commas in object literals, function call argument lists, and callbacks (primarily around WebRTC handling and error messages). This is a non-functional style change to match the project's code style (e.g., Prettier/ESLint) and should not affect runtime behavior.
Remove the uuidv4 import and introduce a local createUUID helper that uses window.crypto.randomUUID when available and falls back to a v4-style generator. Update webrtcClientId and webrtcSessionId to use createUUID(), removing the external dependency while preserving UUID generation for WebRTC session/client IDs.
Add trailing commas to multi-line function calls and RTCPeerConnection instantiation in Dashboard.jsx for consistent formatting. In Media.scss remove an extra blank line and relocate the .media-filters__field:first-child rule to consolidate related styles. Purely stylistic/organizational changes with no intended behavior change.
Reformat code in ui/src/pages/Media/Media.jsx for readability: wrap long argument lists (getTimestampFromInput, buildEventFilter) and reflow the appliedFilter ternary onto multiple lines. Also add the missing trailing newline to ui/public/locales/en/translation.json. No functional changes.
Switch MQTT client to persistent sessions by setting CleanSession to false, enabling ResumeSubs and using an in-memory store. Previously CleanSession was true and resume/store were commented out, which could drop subscriptions on reconnect; these changes ensure subscriptions are preserved across reconnects and re-subscribed from memory.
Introduce structured WebRTC handshake signaling and client-side fallbacks. Changes:
- machinery: replace HandleLiveHDHandshake channel to carry LiveHDHandshake (payload + signaling callbacks) and expose active WebRTC reader count in dashboard data.
- routers: MQTT and WebSocket handlers now send/receive LiveHDHandshake structs; websocket supports stream-hd and webrtc-candidate messages and uses callback-based signaling to reply over the WS connection.
- webrtc: add helper functions to send MQTT or callback answers/candidates, adapt InitializeWebRTCConnection to the new handshake type, and expose GetActivePeerConnectionCount.
- utils: minor GetMediaFormatted filtering fix and unit test for timestamp range behavior.
- ui: Dashboard gains native WebRTC liveview with fallback to SD image stream, shows active listener count, and handles signaling/candidates; Media page adds datetime range filters, infinite-scroll append behavior, and styles; reducer/action updates to support appending events; package.json scripts disable ESLint plugin during start/build/test.
These changes enable browser-based HD liveviews with dual signaling paths (websocket callbacks or MQTT), improve media filtering, and provide graceful fallback to SD streaming when WebRTC fails.
Increase HD handshake channel buffer and harden signaling flow: enlarge HandleLiveHDHandshake buffer from 10 to 100 and add a nil-check to drop and log requests when the channel is not initialized. Add publishSignalingMessageAsync to publish MQTT messages with timeout and error logging, and replace blocking Publish().Wait() calls for ICE candidates and SDP answers with the async publisher. Reintroduce the remote-candidate processor goroutine after remote description handling to avoid AddICECandidate races. These changes reduce blocking, improve error handling, and make WebRTC/MQTT signaling more resilient.
- Enable automatic reconnection for MQTT with configurable intervals and timeouts.
- Add logging for connection loss and reconnection attempts.
- Refactor WebRTC connection cleanup to ensure proper resource management on disconnection.
- Improve event handling in ImageCanvas and Dashboard components for better performance and reliability.
When setting the AVC descriptor fails in MP4.Close(), attempt a fallback that constructs an AvcC/avc1 sample entry from available SPS/PPS NALUs. Adds github.com/Eyevinn/mp4ff/avc import and two helpers: addAVCDescriptorFallback (builds a visual sample entry, sets tkhd width/height if available, and inserts it into stsd) and buildAVCDecConfRecFromSPS (creates an avc.DecConfRec from SPS/PPS bytes by extracting profile/compat/level and filling defaults). Logs errors and warns when the fallback is used. This provides resilience against SPS parsing errors when writing the MP4 track descriptor.
Replace direct sanitizeParameterSets usage with normalizeH264ParameterSets and normalizeH265ParameterSets in mp4.Close. The new functions split Annex-B blobs, strip start codes, detect NALU types (SPS/PPS for AVC; VPS/SPS/PPS for HEVC), aggregate distinct parameter sets and fall back to sanitizeParameterSets if none are found. Added splitParamSetNALUs and formatNaluDebug helpers and debug logging to output concise parameter-set summaries before setting AVC/HEVC descriptors. These changes improve handling of concatenated Annex-B parameter set blobs and make debugging parameter extraction easier.
Fill missing SPS/PPS/VPS from camera config before closing recordings and warn when parameter sets are incomplete (for both continuous and motion-detection flows). Sanitize parameter sets (remove Annex-B start codes and drop empty NALUs) before writing AVC/HEVC descriptors. Prevent creation of empty MP4 files by flushing/closing and removing files when no audio/video samples were added, and only add an audio track when audio samples exist.
Add updateVideoParameterSetsFromAnnexB to parse Annex B NALUs and populate missing SPS/PPS/VPS for H.264/H.265 streams. Call this helper when adding video samples so in-band parameter sets can be recovered early. Also add error logging in Close() when setting AVC/HEVC descriptors fails. These changes improve robustness for streams that carry SPS/PPS/VPS inline.
