Deivid Soto 0f4ad67827 fix(transcode): make preset libx264-only + restore quality opt-in 
Two issues with the 0.9.9 preset retune:

1. applyDefaults was filling Preset="veryfast" before
   ResolveEncoderProfile got to pick the latency-biased default, so the
   "superfast" change never reached users with a freshly-generated
   config.toml — only those who left the field empty saw it.

2. The configured preset was being passed through to every encoder.
   That's only valid for libx264 (ultrafast…veryslow); NVENC uses p1-p7
   and rejects anything else, QSV uses its own subset. A user with NVENC
   + preset="veryfast" would have ffmpeg reject the argv.

Now:
- TranscodeConfig.Preset documented as libx264-only with the full
  range + advice on quality vs first-start latency.
- Default in applyDefaults is empty (was "veryfast") so the engine
  fills in "superfast" on libx264.
- ResolveEncoderProfile ignores configuredPreset for vendor encoders
  (NVENC sticks to p3, QSV to veryfast, VideoToolbox has no preset
  knob). Test cases updated to lock in this behaviour.

Users who want better quality at slower first-play should set
download.transcode.preset = "veryfast" (previous default) / "faster" /
"fast" / "medium" in their config.toml.

Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[0.9.9] - 2026-05-27

Added

  • per-session encoder log: every HLS session start now logs encoder=… accel=… preset=… so a "preparando sesión" complaint can be triaged from the journal alone. Cache-HIT sessions keep the existing simpler log (no ffmpeg involved).
  • probe cache: engine.ProbeFile is memoised by (path, mtime, size) for 30 minutes. A second play of the same file skips ffprobe entirely — saves 1-3 s on first-segment latency for 50+ GB MKVs. Cache key changes immediately on any file rewrite (mtime or size delta).
  • agents tab transcoder row: the web profile → agents tab now shows each agent's selected encoder (NVIDIA NVENC, Intel Quick Sync, VA-API, macOS VideoToolbox, or Software (libx264) in amber) plus the comfortable transcode-resolution cap. Surfaces the same diagnostic the daemon log carries.

Changed

  • HLS encoder presets biased for first-start latency:
    • libx264: default veryfast → superfast (~15-20% faster encode; marginal quality loss at 5-25 Mbps target bitrates). Users wanting the previous quality can set download.transcode.preset = "veryfast" in config.toml.
    • NVENC: -preset p4 -tune hq → -preset p3 -tune ll. First-segment encode drops from ~1.5 s to ~0.8 s on RTX-class GPUs.
    • QSV: -preset medium → -preset veryfast. Keeps -look_ahead 0 for low-latency rate control.
    • VideoToolbox (macOS): adds -realtime 1 -q:v 50 (was unset). The realtime flag steers VideoToolbox into the low-latency code path.
  • Encoder + preset selection moved into engine.ResolveEncoderProfile so the same logic drives both argv construction and the log line.
  • download.transcode.preset is now libx264-only. The configured preset is honoured on software encode (libx264 vocabulary: ultrafast → veryslow); HW backends ignore it and use vendor-specific defaults (NVENC p3, QSV veryfast). Passing a libx264 preset to NVENC / QSV was previously rejected by ffmpeg; the documentation now reflects what was always the only correct usage.
  • Default download.transcode.preset is empty (was "veryfast"). The engine fills in "superfast" for libx264 — latency-biased. Users who want better quality at slower first-play should set it explicitly in config.toml: "veryfast" (previous default) / "faster" / "fast" / "medium". Range documented in the TranscodeConfig struct.

[0.9.8] - 2026-05-27

Fixed

  • auto-upgrade restart loop: when the server signal arrived for a version the daemon was already running (e.g. flag still set after a previous upgrade), applyAutoUpgrade would call upgrade.Execute (which no-ops), then os.Exit(0) anyway — systemd respawned, the flag was still set, the cycle repeated. Now: no-op case is detected up front, the daemon clears the server flag via /api/internal/agent/upgrade-result and stays alive.
  • upgrade flag stuck after success: the CLI never reported the upgrade outcome, so upgrade_requested stayed true in the DB forever. The daemon now calls /api/internal/agent/upgrade-result on every applyAutoUpgrade branch (success, failure, no-op) — server clears the flag, restart loops end.

Added

  • New Client.ReportUpgradeResult(agentID, success, version, error) HTTP method wrapping POST /api/internal/agent/upgrade-result.

[0.9.7] - 2026-05-26

Added

  • hls cache: persistent fMP4 segment cache keyed by (source, quality, audio_index). After a successful encode the segments
    • init.mp4 are kept under ~/.cache/unarr/hls-cache/{key}/ with a .complete marker. A second play of the same file at the same quality skips ffmpeg entirely (smoke-tested 23–31× faster than re-encode). LRU
    • size-budget eviction; pinned during active play; per-key writer-lock prevents two concurrent encodes from corrupting each other. Startup reaps orphan dirs without .complete older than 10 min so a daemon crash doesn't leak disk indefinitely. New [downloads.hls_cache] block in config.toml: enabled (default true), size_gb (default 5, min 1), dir (default ~/.cache/unarr/hls-cache).
  • hls cache integrity check: on HIT, the daemon stats init.mp4 + last segment before reporting cache reuse — if a file was externally deleted, the entry is invalidated and re-encoded transparently.
  • hls cache stats: hit/miss counters surface via cache.Stats() (Hits, Misses, EntryCount, TotalBytes) and the sweeper logs a daily summary line [hls_cache] day-stats: hits=N misses=M ratio=X% entries=Y size=ZMB.
  • subtitle integrity for cached replay: Close waits up to 15 s for the subtitle extractor goroutine before sealing .complete so a HIT never serves half-written .vtt files. Timeout invalidates instead of sealing.

Changed

  • [daemon] auto_upgrade now appears in fresh config.toml files as true (it was always the implicit default; this just makes it visible in default-generated configs).

[0.9.6] - 2026-05-26

Added

  • auto-upgrade: when the web flags the agent for upgrade (POST /api/internal/agent/upgrade or the "Force update now" button), the daemon now downloads and replaces the binary in-place, then exits so the service supervisor (systemd Restart=always on Linux, the equivalent on macOS/Windows) respawns on the new version. No unarr update step required from the user. Still opt-in — only fires when the server sends the upgrade signal.

Changed

  • The OnUpgrade daemon callback no longer just logs run unarr self-update; it now triggers the actual upgrade in a background goroutine.

[0.9.5] - 2026-05-26

Added

  • funnel: optional CloudFlare Quick Tunnel subprocess. unarr funnel on spawns cloudflared as a child process and registers an anonymous https://<random>.trycloudflare.com hostname tunnelled to the daemon's HLS server. The hostname is reported back to the web on every sync so the in-browser player picks it up automatically — cross-network playback now works on torrentclaw.com without Tailscale or port forwarding. Bytes proxy through CloudFlare; TorrentClaw still doesn't relay content.
  • funnel: on by default for fresh installs (NAS/Docker get cross-network HTTPS automatically); existing configs that pre-date the feature stay off until the operator runs unarr funnel on.
  • funnel: auto-downloads cloudflared to the unarr data dir when not on PATH (Linux amd64/arm64/armhf/386). ELF magic + size sanity check on the download; O_EXCL partial-write so concurrent daemons don't clobber each other.
  • funnel: subprocess supervisor keeps the tunnel up across cloudflared crashes + CF's ~6h Quick Tunnel rotation. Exponential backoff (2 s → 5 min) on persistent failures. The web's reported URL is cleared the moment cloudflared exits so an outdated hostname doesn't keep handing out 502s.
  • funnel: unarr funnel status shows the live URL once registered. See README §[downloads.funnel] for the throughput / latency caveats of CF's free Quick Tunnels.
  • docker: the official torrentclaw/unarr image now bundles cloudflared so the funnel works the moment the container starts — no first-run download.

Fixed

  • hls/libx264: bump the H.264 level we hint to libx264 by one tier so anamorphic (>16:9) sources stop emitting unplayable streams. 720p at level 3.1 silently rejected 1728×720 cinemascope frames with frame MB size > level limit; 720p now ships at level 4.0, 1080p at 4.1. Decoder compatibility is unaffected — every device that handles 1080p already handles ≥ 4.1.

[0.9.4] - 2026-05-26

Removed

  • streaming: retire the custom WebRTC DataChannel pipeline. The daemon no longer ships pion/webrtc, the WSS signaling client, or the wire framing package — every in-browser session now uses HLS over HTTP from the daemon (Tailscale / LAN / UPnP). Browser P2P (WebTorrent) bytes never re-enabled.
  • config: [downloads.webrtc] block removed from the TOML schema; existing config files with the section parse cleanly because go-toml ignores unknown sections.
  • seed_file: mode=seed_file task handler + engine.SeedFile helper dropped — the last in-browser caller was retired with the WebRTC player.
  • wstracker-probe: standalone probe binary removed.

Changed

  • agent wire: SyncResponse.WebRTCSessions (JSON: webrtcSessions) renamed to StreamSessions (JSON: streamSessions). The Go type agent.WebRTCSession is now agent.StreamSession. Wire-incompatible with web < 2026-05-26.
  • torrent: buildMagnet no longer accepts an extraTrackers variadic — the default tracker list is the only set used.

Fixed

  • hls: clamp the ffmpeg -b:v to the bitrate cap derived from the EFFECTIVE output height instead of the requested quality. Previously asking for "2160p" on a 1080p source overshot the H.264 level we resolved from the effective height (4.0, max 20 Mbps) and made libx264 abort with VBV bitrate > level limit.

[0.9.2] - 2026-05-21

Added

  • vpn: unarr vpn command (status, enable, disable) to manage the managed WireGuard split-tunnel, with vpn status --check to verify provisioning.
  • vpn: report split-tunnel state (active, exit server) to the web on register
    • every sync, so the dashboard shows which agent holds the single WireGuard slot.
  • vpn: send the agent id when fetching the VPN config so the web can arbitrate the single WireGuard slot — the first agent claims it; the rest are told to run OpenVPN on their own host (1 agent on WireGuard + up to 9 on OpenVPN).
