Follow-ups on the daemon HLS pipeline (0fc0e1c):
- engine/hls.go HLSSession.Register now closes every other active
session in the registry. Modeled as "one viewer == one transcode" so
repeated quality switches or page reloads don't leave orphan ffmpegs
saturating the CPU until the idle sweeper reaps them 30 min later.
- engine/hls.go restartFromSegment kills + respawns ffmpeg with
-ss / -output_ts_offset / -start_number when the browser asks for a
segment far ahead of the writer head. Segments already on disk stay
cached. Without this, a user dragging the scrubber to minute 30 of a
fresh stream blocks until the encoder reaches minute 30 in real time.
- engine/hls.go subtitle disambiguation: never set DEFAULT=YES on any
rendition (anime forced "signs only" tracks were autoselected and
rendered nothing during opening dialogue, looking broken). Names get
numeric suffixes when language is duplicated; FORCED tracks get a
"(forzados)" suffix.
- engine/hls.go ProbeInfo() exposes codec / audio / subtitle metadata
to the new GET /hls/<id>/probe.json endpoint for the player's info
badge + bandwidth logic.
- engine/hls.go scale chain fix: chains a trunc(iw/2)*2 scale after
the height cap so libx264 stops rejecting odd widths (853x480 etc.).
- engine/hls.go HW encoder tuning: NVENC -preset p4 -rc vbr -tune hq,
QSV -preset medium.
- engine/stream_server.go routes /hls/<id>/probe.json to the session.
- cmd/daemon.go runs an idle sweeper goroutine every 5 min, reaping
sessions whose last segment fetch was >30 min ago.
Introduces an HLS-over-HTTP path as Plan B for in-browser streaming. The
WebRTC + MSE pipeline keeps working untouched; the new path is selected
when the backend sets transport="hls" on a streaming session.
Daemon scope:
- engine/hls.go: HLSSession + HLSSessionRegistry. Spawns ffmpeg with
-f hls -hls_segment_type fmp4 + force_key_frames aligned with 4 s
segments. Pre-renders master + media playlists from the probe duration
so the browser knows the total timeline before any segment exists,
fixing seek/duration/pause/multi-track issues seen with the live fMP4
pipe.
- engine/probe.go: enumerate every audio + subtitle track instead of
collapsing to a single default audio track.
- engine/stream_server.go: route /hls/<id>/{master.m3u8,video/...,
subs/...} to the matching session. Emit a synthesised single-VTT
subtitle playlist per text track; bitmap subs (PGS/DVB) skip silently.
- cmd/daemon.go: branch on WebRTCSession.Transport == "hls" to register
an HLS session instead of running the legacy DataChannel pump.
- agent/types.go: WebRTCSession.Transport + AudioIndex fields.
Backend + web sides land in a follow-up commit.
Three root-cause fixes for VLC showing a black screen when opening a
stream from a different network or via Tailscale:
1. PrioritizeTail: when VLC opens an MKV/MP4 stream it immediately seeks
to the end of the file to read the container index (seekhead/moov
atom). For active torrents those end-pieces aren't downloaded yet, so
the reader blocks indefinitely. PrioritizeTail() opens a background
reader positioned at the last 5 MB, keeping those pieces at high
priority until ctx is cancelled or they finish downloading.
2. /health endpoint: GET /health returns a lightweight JSON response
{"status":"ok","streaming":bool,...} so connectivity can be tested
with a simple curl from any device before involving VLC.
3. Per-request logging: every incoming /stream request now logs the
client IP and Range header, making it trivial to confirm whether
remote/Tailscale clients are reaching the server at all.
Replace Range-header-based progress tracking with a trackingReader that
measures actual bytes read per connection. This gives accurate playback
position even for local/NAS files where VLC buffers aggressively.
- Token bucket rate limiter at 2x video bitrate (from ffprobe)
- CAS loops for lock-free atomic progress updates without regression
- probeMediaInfo extracts bitrate + duration via ffprobe (3s timeout)
- Defense-in-depth: only probe regular files, reject FIFOs/devices
- Remove dead parseRangeStart function
- Consistent [stream] log prefix
Replace anacrolix/upnp with huin/goupnp + custom NAT-PMP (RFC 6886)
implementation. NAT-PMP is tried first (faster, more compatible with
TP-Link routers), with UPnP-IGD SOAP as fallback. Gateway detection
reads /proc/net/route for accuracy. Includes unit tests with mock
NAT-PMP server and permanent e2e tests (build tag manual).
Track the highest byte offset served by the stream server to estimate
playback progress (0-100%). A WatchReporter goroutine sends progress
to POST /api/internal/agent/watch-progress every 10s during streaming.
- Add maxByteOffset + totalFileSize to StreamServer for Range tracking
- Add FileSize() to fileProvider interface (all 3 providers)
- New WatchReporter: periodic progress reporter tied to daemon context
- New WatchProgressUpdate type with optional progress/position/duration
- Wire reporter into all 3 stream paths (task stream, disk stream, active download stream)
- Replace `upgrade` stub with real command (alias for `self-update`)
- Also register `update` as alias: `unarr update` works too
- Rewrite `status` to show full config, disk usage, daemon state, and
update availability with colored sections
- Add version check cache (1h TTL) so `status` is instant on repeat runs
- Guard against division by zero on empty filesystems
- Guard against negative durations from clock skew
- Guard against stale PID via heartbeat recency check (2 min)
- Add comprehensive test coverage across agent, engine, upgrade, usenet,
arr, library, mediaserver, and UI packages
- Improve Makefile coverage target to exclude cmd/ glue code
- Fix stream handler resource cleanup and ffprobe error handling
- Add UPnP discovery and automatic port mapping (like Plex Remote Access)
- Stream server binds to 0.0.0.0 and reports public IP via UPnP
- Fallback chain: UPnP public IP → Tailscale IP → LAN IP
- Clean up port mapping on shutdown
- Bump version to 0.3.0-dev
- Migration wizard from Sonarr/Radarr/Prowlarr (unarr migrate) [pre-beta]
- Auto-detect instances via Docker, config files, port scan, Prowlarr
- Import wanted list (monitored+missing movies/series)
- Import download history and blocklist to avoid re-downloading
- Extract debrid tokens from *arr download clients
- Quality profile mapping to preferred_quality config
- DISTINCT ON PostgreSQL query for optimal torrent selection
- JSON export with --dry-run --json (text to stderr, JSON to stdout)
- Media server detection (Plex/Jellyfin/Emby) in unarr init
- Detects library paths and offers them as download directory options
- Debrid auto-configuration in unarr init
- Scans *arr instances for debrid tokens
- Validates and saves via API if user confirms
- New preferred_quality setting in config (2160p/1080p/720p)
- Library scan command (unarr scan) with ffprobe metadata extraction
- Add daemon state persistence and stale resume file cleanup
- Add TriggerPoll for WebSocket resume actions
- Improve stream server with graceful shutdown and connection tracking
- Add desktop notifications for download completion
- Add media file organization with Movies/TV Shows detection
- Improve usenet downloader with progress tracking and resume support
- Add self-update package with GitHub release verification
- Downgrade tablewriter to v0.0.5 (v1.x API breaking change)
