README: Live view

Live view: sound, 360p-1080p + full-size qualities, smoother catch-up
- Sound: the default output's pulse monitor (what the headset plays) as AAC in the same fMP4; the player starts muted (browser autoplay rules) with a Sound on button. Video timestamps go to the wall clock (-ts mono2abs) instead of forcing it on the pulse input, which gave bursts of AAC packets one shared timestamp; aresample=async=1 keeps the sound continuous. - Late viewers start at a keyframe of the video track (audio samples are all sync). - Qualities 360p/480p/720p/1080p scale down only; 'full' sends SteamVR's headset view at its own size (1920x1080 today; v4l2cam has no size option, so 2K/4K would only upscale). - Player keeps a 0.3 s cushion and catches up at 1.1x; it seeks only when >2 s behind (seeking to the very edge starved playback).

-**Steam library failures (GitHub #21/#30):** on some Frames Steam never loads FramePort's shortcuts.vdf entries (same SteamOS build and arm64 beta client as the dev Frame; IDs correct; file written before Steam starts): Play → console_log `GameAction [AppID <id>] … RequestingLicense → UpdatingAppInfo → LaunchApp failed with AppError_9` (= "Game configuration unavailable", Steam treats the id as a store app).

Ids: letter first, then letters/digits/_ only (spaces, '-', leading digit → "missing/invalid arguments"). Later Plays use the devkit entry; uninstall (`devkit_unregister`, `delete-shortcut` live) and purge remove it. Verified on the dev Frame: register/launch/unregister; the AppError_9 trigger itself only in unit tests. GitHub #42 (two Steam accounts, neither MostRecent): Steam rewrote the active account's shortcuts.vdf without FramePort's entries right after starting, and added the devkit entry live without saving it, so `devkit_appid` (vdf only) failed ("Steam added the devkit entry but didn't save it"); agent v55 `devkit_appid_from_log` reads Steam's `sanitize shortcut app id "~/devkit-game/<id>/launch.sh": replacing 0 with N` console line. GitHub #41 (one account): same Steam behaviour, and every install restarts Steam, which forgets the never-saved devkit entry. Agent v56: the log fallback reads only the current session's console_log.txt; Play re-registers a devkit entry that gets AppError_9; art updates also write the devkit entry's grid art (`copy_grid_art`). Open: why some Frames' Steam never loads or saves shortcuts.vdf (single account too).
 **Exit game (GitHub #36, 2026-10-04):** `Apps.TerminateApp` (what Exit game calls; reachable for tests through Steam's CEF devtools on 127.0.0.1:8080, SharedJSContext, `Runtime.evaluate` — a stdlib websocket client is enough) closed both a normal shortcut and a devkit entry on the dev Frame within 1-3 s. SIGTERM to Steam's `reaper` alone left launch.sh + Lepton (setsid) + the container running (an earlier headset launch ran on for 87 min); SIGTERM to launch.sh cleans up in ~4 s. Agent v44: launch.sh's 2 s loop ends the game when its parent (the reaper) is gone; `upgrade_launchers` (from ensure_host_fixes) adds that to existing launchers in place. Which in-headset exit path fails is still unknown. Screenshots on the Frame: all under SteamVR's appid 250820 (`760/remote/250820/screenshots`, screenshots.vdf has creation time, no game).
 **SteamVR dashboard at game start (2026-10-04):** the dashboard (Resume game / controller / VR options) was open whenever a FramePort game started (also over Lepton's 2D launcher). Steam's UI exposes `SteamClient.OpenVR.VROverlay.{IsDashboardVisible,HideDashboard,ShowDashboard}` (CEF devtools, `steam_js` in the agent). Agent v44: launch.sh starts `_dashboard_worker` (waits for FrameBridge's first `pacing:` line in launch.log, then hides a visible dashboard for 25 s, at most 3 times; log `<base>/dashboard.log`; opt out with env FRAMEPORT_KEEP_DASHBOARD=1). Verified on the dev Frame (dashboard shown → 4XVR launched via Steam → hidden ~5 s after the first frames); not yet seen in the headset. **Headset (ITR2, 2026-10-05): too late** — Steam shows its frame menu (`valve.steam.gamepadui.frame.menu`, vrwebhelper_systemui.txt `[PooledPopups] Showing`) ~0.3 s after the game's first submitted frame (FrameBridge `new layer:`), but the first `pacing:` summary comes ~8 s later; the owner had pressed Resume (`[HideDashboard] return_to_game`) before the worker looked. Agent v52: watches from the first `new layer:` line (incremental log reads, 0.5 s polls, 30 s window). Agent v53: stops for good once the player opens the dashboard with the controller (`toggle_dashboard_action` in vrwebhelper_systemui.txt since the worker started): v52 closed it 60 ms after each press, and the game, paused for it, stayed paused.
 **Space warp / ITR2 (2026-10-04):** Into The Radius 2 (UE5, `libUnreal.so` + OVRPlugin, Vulkan) uses Application SpaceWarp (extra swapchains `376x376 format=97` motion vectors + `format=129` depth); #35 reports flickering textures. OVRPort's `patch_disable_space_warp` has no effect on UE5, and hiding XR_FB_space_warp in FrameBridge's enumerate doesn't reach the game either: **OVRPort's dispatcher offers/enables XR_FB_space_warp itself**. FrameBridge `hide_space_warp` (per game, off) hides it and strips `XrCompositionLayerSpaceWarpInfoFB` (1000171000) from the projection views (log `hide_space_warp: removed space warp info`); the game still renders its MV swapchains. Test build installed on the dev Frame; flicker not yet checked in a headset. Heuristic: UE5 + OVRPlugin shows it as an option (off). `equirect_emul` is suggested for Unreal games whose graphics API isn't detected ("GLES or unknown"); on Vulkan it switches itself off (Myst/Riven/ITR2): harmless, but Unreal Vulkan detection is a known gap.
 **PR #34 (merged 2026-10-04, Lucas-Mathieu):** `native/adapter/audio_metadata.h` patches Meta XR Audio Wwise (only build ID e1619e7f…, Batman: Arkham Shadow 1.4.1) so queued audio metadata isn't freed while the current audio frame references it (smoke-bomb crash). Verified headless: installs ("metadata reclamation follows …"), 72 fps; we added a once-per-second scan limit. Outside PRs: review source, rebuild `artifacts/` ourselves, merge locally (contributor's commit kept), push main.
 **Heuristics eval (2026-10-04):** `scripts/eval_heuristics.py "<VR CyberDeck Portable>"` → 19/44 recipes exact, 322/352 fields (most diffs: `frame.unity_text_input` suggested where older catalog recipes lack it; the rest are runtime-only findings: use_alt, vk_shader_fix, focus_hold, sync_guard, multipass). `PATCHED/` copies aren't scored (already converted).
-**Power (0.9, agent v47):** sidebar bar above the Frame card: Sleep / Restart / Shut down, each confirmed (`app.frame_power`, a running game asks again). logind answers CanSuspend/CanReboot/CanPowerOff = "challenge" for an SSH session but "yes" inside a user unit, so agent `power` runs `systemctl suspend|reboot|poweroff` from a transient `systemd-run --user --on-active=3` timer (the command answers first). Restart verified on the device (back in ~84 s, new boot id).

Restart verified on the device (back in ~84 s, new boot id).
 **Proton default (agent v51, owner's choice 2026-10-05):** the newest **stable** ARM64 Proton is the default for PC VR games (`pick_proton`: asked-for name/alias, else newest installed stable, else any stable). Agent v49-50 defaulted to Experimental; the owner's headset A/B with Rick and Morty (Experimental 69 % reprojected frames, stable felt much smoother) reverted it. The game page's Customize shows `pcvr.proton_tool` as a dropdown (Stable (default) / Experimental = alias `proton-experimental`); `ensure_proton` installs a chosen one (it asks once more for the runtime Steam only names after Proton is installed; Experimental installed unattended on the device in 53 s). A PC VR launch test that fails on stable suggests Experimental (`pipeline.PROTON_TOOL`, `proton_alternative_worth_trying`, button "Try Proton Experimental and reinstall"). Remaining Rick and Morty stutter on head turns = the game rendering below the refresh rate (reprojection), not Proton.
 **USB cable link (verified 2026-10-05, cabled to the dev PC):** `usb0` is a USB **NCM** gadget (configfs g1: `ncm.usb0` + `ffs.adb`, Valve 28de:2460) set up by `usb-ncm-gadget@usb0.service`, which only runs with `ConditionPathExists=|/etc/systemd/system/adbd.service.d/steamos-devkit-enabled` = **Developer Mode only**. `usb-ncm-dnsmasq@usb0` serves DHCP with fixed `dhcp-host` entries: Frame 10.86.200.233, PC **10.86.200.234** (`frame/usb.py` FRAME_USB_IP/PC_USB_IP). Windows 11 binds its built-in "UsbNcm Host Device" (no driver); WSL mirrored sees eth 10.86.200.234. USB is high-speed (USB 2.0): upload 36.9 MB/s vs 11.3 MB/s home Wi-Fi. Frame→PC over the cable worked without a firewall change. `scripts/usb_autotest.py` (Windows via powershell.exe from WSL), `frameport frame usb-check`. Wizard "Set up with a USB cable" (`PairingServer(host=PC_USB_IP)`; the real bootstrap ran end to end over USB). Discovery dedupes by SSH host key and prefers USB > Frame hotspot > network (`discovery.dedupe`); a lost address is re-found by key (`Frame.relocate`, tested with a dead saved address).
 **Catalog updates without a release (2026-10-05):** apps fetch `catalog/games/*.yaml` from GitHub `main` (`recommend/catalog.refresh_remote`: one API call `git/trees/main?recursive=1` + raw.githubusercontent downloads of changed blobs, cached as `catalog-gh-<sha>.yaml`, every 6 h; GUI at start + Settings → Data "Check now"; CLI background thread + `frameport catalog-update`). `catalog.load()` only reads the cache. A remote entry is skipped (`unusable_reason`) when it names a patch/adapter key this app doesn't register, has a field `CatalogEntry` doesn't know, or `min_app` > this version: add `min_app` (or rely on new patch ids) when a config needs an unreleased FramePort. Remote beats bundled unless the bundled entry has a later updated/verified date; the user's own entries still win as before. Off: setting `catalog.auto_update`, env FRAMEPORT_NO_CATALOG_UPDATE; FRAMEPORT_CATALOG_URL still overrides the source. So: **pushing a catalog change to main reaches users within 6 h** (their recipes follow via catalog_rev → Update on Frame).
+**Start activity / QuestCraft / ITR2 pop-in (2026-10-05):** WiiCompiled's VR part (`QuestActivity`, SDL, process `:game`) stays behind Lepton's flat window when the launcher is shown (`device.text_input_window`). `frame.start_activity` (opt-in; analysis `extra.vr_activity` = the original APK's activity with Meta's VR category when it isn't the launcher) gives that activity's filter LAUNCHER and every other LAUNCHER becomes INFO, per element (`axml.set_start_activity`); Lepton's own `apk-info-extractor --print-activity-name` (on the Frame under Lepton/liblepton/apk_extractor) then answers QuestActivity. **OVRPort gives every MAIN activity LAUNCHER + VR categories**, so the VR activity must come from the original APK's analysis, not the converted manifest. Lepton has no activity override (`APP_ACTIVITY` is reset when app_metadata.sh is sourced). QuestCraft reaches Minecraft 1.21.5 (Fabric, Vivecraft, Sodium; LTW "Large Thin Wrapper" GL 3.0 on the Frame's Zink) and stops at `OpenGL error 1282` in `WindowFramebuffer` createTexture (Minecraft's crash report in `files/instances/1.21.5/crash-reports/`, Pojlib's `files/latestlog.txt`); the vrclient SIGSEGV / "pthread_mutex_lock called on a destroyed mutex" afterwards is only the shutdown (Unity's render thread still in vrclient while the instance is destroyed). ITR2 "models popping in and out" in game: Unreal reads user config from **internal** storage (`lepton-data/internal/<pkg>/files/UnrealGame/<Project>/<Project>/Saved/Config/Android/Engine.ini`, not external); `r.AllowOcclusionQueries=0` there broke its menus (removed again). Vulkan shim `vk_query_slots` (two slots per occlusion query) never saw ITR2 create an occlusion query pool, and the run with it crashed (Unreal RenderThread SIGSEGV, caught by sentry-native: no tombstone; the backtrace is in `cache/sentry/*/.sentry-native/*.run/*.envelope` with module offsets) - left off. Next suspect: Unreal 5 mobile HZB occlusion reading depth stored with Valve's FDM injection layer; test = launcher `VK_INSTANCE_LAYERS=''` (Lepton then loads neither VALVE_rpo nor VALVE_fdm_injection, Fossilize still). QuestCraft: LTW overrides glGetError and returns 0 with `LIBGL_NOERROR` set; Lepton passes `LEPTON_ENV_<NAME>` to the app as `<NAME>`, so catalog `lepton_env: {LEPTON_ENV_LIBGL_NOERROR: '1'}` gets Minecraft past the GL error 1282; then black picture (see the catalog entry). FrameBridge logs `new layer` once per layer type per process and projection views only for the first frames, so a second session in the same process (Vivecraft after Unity) needs `layer_debug=1`.
+**Vulkan validation / ITR2 solved (2026-10-05):** Khronos' validation layer can't come from Lepton (its layer dir is in the read-only guest image; the Linux copies on the Frame are glibc) and a global `debug.vulkan.layers` property (via the LEPTON_GFXRECON_FP_PROPS trick) kills the container at boot. Working recipe: bundle `libVkLayer_khronos_validation.so` (Khronos android-binaries release, arm64-v8a, stored uncompressed) into a test APK re-signed with the game's key (`apk.sign.sign`), install with `frameport install <pkg> --apk`, and set the Vulkan shim's `vk_validation=1` (it adds the layer at vkCreateInstance; findings under the logcat tag VALIDATION in launch.log, each message ID capped at 10). ITR2's flicker + windows behind models = Unreal's Qualcomm shader-resolve subpasses with a depth resolve of a single-sampled depth attachment (VUID-04908/-03179); `vk_spec_fixes=1` drops that resolve (its TRANSFER_DST half never applies to ITR2: the main depth is transient). Valve's VALVE_rpo layer removed ITR2's fog (catalog `lepton_env: VK_INSTANCE_LAYERS: VK_LAYER_VALVE_fdm_injection`). `r.ViewDistanceScale=2` in the internal Saved/Config/Android/Engine.ini only exists on the owner's Frame (the catalog can't write internal storage yet). Launch tests: Lepton prints a transient "is not a running context" on the first start after an APK change (agent v54 `not_started` waits 30 s for "Boot complete!").
+**GitHub #38/#39 (2026-10-05):** PowerWash Simulator stuck at "Waiting.." on a reporter's Frame = Unity sized the right-eye image rect past its swapchain (rect 268+1656 on a 1920-wide swapchain; the runtime's recommended size differs per Frame) and SteamVR rejected every frame (`xrEndFrame failed -25`, XR_ERROR_SWAPCHAIN_RECT_INVALID), after which the game stopped calling xrEndFrame. FrameBridge `rect_clamp` (default on; sizes noted in xrCreateSwapchain; clamped layers count as swapped) keeps projection/quad rects inside their swapchain; triage `swapchain-rect-invalid`. Not reproducible on the dev Frame with `scale` (Unity's eye sizing isn't just the recommended width); no regression there (72 fps). The adapter's revision was NOT bumped (that would mark every installed game outdated): affected users rebuild. The Room VR (#38) = Unity's render thread SIGSEGV in libgallium_dri.so ~30 ms after the game recreates its eye swapchain with samples=4 (FrameBridge retries samples=1); the game's own code turns MSAA on (not OVRManager); candidate fix: hide GL_EXT_multisampled_render_to_texture (GL shim) - needs the APK to test. The launch test passed both (render thread dead / no frames): triage gap.
 **Lepton storage (2026-09-30):** each app's /sdcard (= /storage/emulated/0 → `<base>/lepton-data/external`) has `Movies`/`Download`/`Documents` symlinked to the Frame's `~/Videos`/`~/Downloads`/`~/Documents` (liblepton/mounting.sh, only if they exist at start); agent v24 `storage_targets` reads that mapping. Android's MediaProvider canonicalises paths to /home/steamos/... and rejects every file ("doesn't appear under [/system/media...]"), `sm list-volumes` is empty: the media index never works, apps must browse folders. Lepton installs with `adb install -g` (runtime permissions granted, MANAGE_EXTERNAL_STORAGE too). Files: `install/files.py`, `frameport frame send|storage`, GUI Files tab (formerly Frame → Send files).
 **SteamVR per-app settings (2026-09-30):** editing steamvr.vrsettings while SteamVR runs is lost; the web API (127.0.0.1:27062 /app/setsettings) needs `x-steamvr-secret`. `native/vrsettings` = `fp_vrsettings.exe` (freestanding, OpenVR `FnTable:IVRSettings_003` as a Utility app, loads SteamVR's bin/win64/openvr_api.dll) sets them live and SteamVR persists them: section `steam.app.<shortcut appid>`, keys `preferredRefreshRate` (float) and `motionSmoothingOverride` (0 global, 1 on, 2 off, 3 always). Steam Link (vrlink) lists the Frame's rates 72/80/90/96/108/120/144 in vrserver.txt and follows the per-app preference ("host preferred N Hz"; whether the key is honoured is unverified in-headset yet). Judder metric: vrcompositor.txt session summary dropped + "Timed out. N total" (Stormland: 0 dropped but 313 timeouts in 2 min); fpsVR (`%LOCALAPPDATA%\fpsVR\*.json`, 0.1 ms histograms) gives p99 CPU/GPU ms. `pcvr.steamvr_tuning` (default on, PC only) applies on Play: highest rate whose budget ≥ p99×1.05, at least one step down, smoothing on.

+  option), so the live view only scales down (360p/480p/720p/1080p) or sends it as is ("full").
+- Sound: `pactl get-default-sink` (`alsa_loopback_device.stereo.alsa_output.platform-sound.HiFi__Speaker__sink`) and its

spoopyghosty0	0e47ce8f1a	Live view: sound, 360p-1080p + full-size qualities, smoother catch-up - Sound: the default output's pulse monitor (what the headset plays) as AAC in the same fMP4; the player starts muted (browser autoplay rules) with a Sound on button. Video timestamps go to the wall clock (-ts mono2abs) instead of forcing it on the pulse input, which gave bursts of AAC packets one shared timestamp; aresample=async=1 keeps the sound continuous. - Late viewers start at a keyframe of the video track (audio samples are all sync). - Qualities 360p/480p/720p/1080p scale down only; 'full' sends SteamVR's headset view at its own size (1920x1080 today; v4l2cam has no size option, so 2K/4K would only upscale). - Player keeps a 0.3 s cushion and catches up at 1.1x; it seeks only when >2 s behind (seeking to the very edge starved playback).	2026-10-05 20:05:06 -04:00
spoopyghosty0	ad924669d3	Live view tab: stream the Frame's headset view to a browser window on the PC Source: SteamVR's built-in v4l2cam headset view (steamvr-v4l2cam.service -> v4l2loopback 'SteamVR'), encoded with x264 on the Frame (fps=30 before scaling, nice 10, 3 threads) as fragmented MP4 over an SSH exec channel; ffmpeg stops when the channel closes. A relay on 127.0.0.1 keeps the init segment and the fragments since the last keyframe for late viewers and serves an MSE player page, opened in the default browser (Flet can't show video outside flet build bundles). Verified on the dev Frame: 30 fps in Edge, ~0.1 s behind the newest frame, 0.34 core at 720p with a quiet picture.	2026-10-05 20:05:06 -04:00

spoopyghosty0	13069db28a	Vulkan shim vk_spec_fixes (per game): depth images get TRANSFER_DST (not transient ones), Qualcomm shader-resolve subpasses lose their invalid depth resolve; found with the validation layer in Into The Radius 2	2026-10-05 18:19:11 -04:00
spoopyghosty0	7058105056	Launch tests wait for a first boot after an APK change (agent v54: Lepton's transient 'is not a running context' stopped them); Vulkan shim vk_validation (diagnostics: adds Khronos' validation layer, bundled in a test APK, to the game's instance; a global debug.vulkan.layers property kills Lepton's container)	2026-10-05 17:59:03 -04:00

spoopyghosty0	bda9045be6	Into The Radius 2: load only Valve's foveation layer (VALVE_rpo removed the game's fog; owner-verified), notes on the remaining pop-in	2026-10-05 17:32:58 -04:00
spoopyghosty0	a7890d46de	QuestCraft works: catalog status works (owner-verified 2026-10-05; LIBGL_NOERROR + frame.ltw_depth)	2026-10-05 17:31:35 -04:00
spoopyghosty0	50ab3eb341	frame.ltw_depth: Minecraft launchers' LTW (QuestCraft) loads OpenGL ES through libfpg.so (native/glshim/eglfmt.c), which turns desktop GL_DEPTH_COMPONENT32 into OpenGL ES depth formats; the Frame's Mesa rejected it, so the depth textures never existed and every framebuffer was incomplete (black picture)	2026-10-05 17:22:52 -04:00
spoopyghosty0	4313b52792	QuestCraft: LIBGL_NOERROR for LTW (Lepton env) gets Minecraft past its GL error 1282 at start (the picture is black next, under investigation); notes on ITR2's popping tests (vk_query_slots and Valve's FDM layer ruled out)	2026-10-05 17:09:33 -04:00
spoopyghosty0	4f9ecf4801	WiiCompiled: notes on "Start straight in VR" (owner-verified: opens in VR without the launcher window; off by default because it skips the launcher's import)	2026-10-05 16:46:12 -04:00

spoopyghosty0	cf900cd9d4	vk_query_slots: in the Game settings dialog (switch, Troubleshooting; Unreal Vulkan games), 1 = on; fix the settings-dialog test and the translation template	2026-10-05 16:37:10 -04:00
spoopyghosty0	ef21b33ca2	Vulkan shim: vk_query_slots (per game) gives occlusion queries one slot per eye; in multiview passes the Frame's Mesa driver writes the second eye's zero result into the next query, culling visible objects (Into The Radius 2's popping models; not yet confirmed in a headset). Sidebar: Sleep / Restart / Shut down below the Frame card	2026-10-05 16:30:07 -04:00
spoopyghosty0	799f1bd9f1	frame.start_activity (opt-in): start an app's VR activity directly instead of its 2D launcher (WiiCompiled's flat window stayed in view after the VR part started); per-element manifest edit, VR activity from the original APK's analysis (OVRPort gives every MAIN activity LAUNCHER + VR); notes on QuestCraft (Minecraft stops at GL error 1282) and ITR2 pop-in	2026-10-05 16:20:31 -04:00
