Ship the Android client's 3-tier stats-overlay semantics in every other client (design/stats-unification.md vocabulary): Off → Compact (one line: fps · e2e ms · Mb/s + loss flag) → Normal (mode + e2e p50/p95 + loss counters) → Detailed (decoder path, HDR tag, per-stage latency equation). Apple: new StatsVerbosity in PunktfunkKit persisted under punktfunk.statsVerbosity (migrates the legacy hudEnabled bool: explicit off → Off, else Normal). The existing three-finger tap (TouchMouse, trackpad/pointer modes only — touch passthrough untouched) now cycles the tiers instead of toggling, matching Android; ⌃⌥⇧S (menu + captured-state monitor) cycles the same ladder. Tiered StreamHUDView (compact glass pill / headline HUD / full equation HUD); the iOS corner disconnect also shows in Compact (the pill carries no button). Tier pickers on iOS, macOS, tvOS and the gamepad settings UI. Session stack (Linux + Windows + Deck share punktfunk-session): shared pf_client_core::trust::StatsVerbosity; Settings grows stats_verbosity with a show_stats fallback, and writes keep the legacy bool in sync so pre-tier binaries reading the same JSON agree on off vs on. Ctrl+Alt+Shift+S cycles the tier and re-renders the OSD immediately from the last stats window; the stdout stats: line always carries the full Detailed text so the shell status card and scripts keep a stable shape; --stats bumps Off → Normal without demoting a richer tier. Tier pickers in the GTK dialog, the WinUI settings page and the console-UI settings row; shortcut copy updated (GTK shortcuts window, Windows help, session README). The Windows legacy builtin path keeps its bool HUD. Tests: tier migration/round-trip in trust.rs, tiered stats_text output in pf-presenter. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

# punktfunk-session
|
|
|
|
The Vulkan session binary: one stream per invocation in an SDL3 window — no UI toolkit,
|
|
no widgets, terminal stats. The power-user / gamescope stream client, and the stage-2
|
|
presenter of the Linux client re-architecture (punktfunk-planning:
|
|
`linux-client-rearchitecture.md`).
|
|
|
|
```
|
|
punktfunk-session --connect host[:port] [--fp HEX] [--launch id] [--fullscreen] [--stats]
|
|
punktfunk-session --browse host[:port] [--mgmt PORT] [--fullscreen]
|
|
```
|
|
|
|
`--browse` opens the console game library (the Skia coverflow over the animated aurora)
|
|
instead of connecting: A launches the focused title as a stream in the same window,
|
|
session end returns to the library, B quits (Gaming Mode returns). Paired hosts only —
|
|
pairing is the desktop client / Decky plugin's job. `PUNKTFUNK_FAKE_LIBRARY=<file.json>`
|
|
feeds canned entries with no host (portrait paths starting with `/` load from disk).
|
|
|
|
Reads the same identity / known-hosts / settings stores as the desktop client
|
|
(`punktfunk-client`) — pair there (or via its headless `--pair`) first; this binary never
|
|
connects to a host it has no pinned fingerprint for (`--fp HEX` overrides the store).
|
|
|
|
Stdout is the machine interface: `{"ready":true}` after the first presented frame,
|
|
`stats: …` once per second while the overlay tier isn't Off (always the full detailed
|
|
text, whatever the OSD shows; `--stats` forces the overlay on), one
|
|
`{"error"|"ended": …}` JSON line on the way out. Logs go to stderr. Exit codes: `0`
|
|
clean end, `2` connect failed, `3` trust rejected / pairing required, `4` presenter
|
|
init failed.
|
|
|
|
In-stream keys match the desktop client: click captures input (Ctrl+Alt+Shift+Q
|
|
releases), Ctrl+Alt+Shift+D disconnects, F11 toggles fullscreen; the controller escape
|
|
chord (L1+R1+Start+Select, hold to disconnect) works the same.
|
|
|
|
The default build carries the Skia console UI (`ui` feature): the stats OSD and capture
|
|
hint render in-window. Ctrl+Alt+Shift+S cycles the OSD tier live — Off → Compact (one
|
|
line: fps · latency · Mb/s) → Normal (mode + end-to-end percentiles) → Detailed (decoder
|
|
path + per-stage latency equation); any tier but Off also emits the stdout mirror.
|
|
`--no-default-features` is the ~5 MB power-user build — same streaming, stats on stdout
|
|
only, no Skia anywhere in the dependency tree.
|
|
|
|
Decode follows the Settings preference (auto: Vulkan Video → VAAPI → software):
|
|
FFmpeg's Vulkan Video decoder runs on the presenter's own device where the stack
|
|
supports it (every vendor, zero copy); VAAPI dmabufs import per-plane elsewhere;
|
|
software is the universal fallback. 10-bit Main10 and HDR10 are advertised
|
|
(`VIDEO_CAP_10BIT|HDR`): P010 decodes through all three paths, and PQ streams present
|
|
on an HDR10/ST.2084 swapchain when the desktop offers one (KDE HDR, gamescope) or
|
|
tone-map in-shader to SDR when it doesn't (`PUNKTFUNK_TONEMAP_PEAK` tunes the rolloff,
|
|
default ≈1000 nits). The host still gates the upgrade behind its `PUNKTFUNK_10BIT`
|
|
policy.
|
|
|
|
Debug/bisect knobs: `PUNKTFUNK_DECODER=vulkan|vaapi|software`, `PUNKTFUNK_PRESENT_MODE=
|
|
mailbox|immediate` (default FIFO), `PUNKTFUNK_VK_DEVICE=<index>` (multi-GPU), and
|
|
`PUNKTFUNK_HW_FAULT=import` (fault every VAAPI dmabuf import — proves the three-strike
|
|
demotion to software on healthy hardware).
