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, open):** on 0.7.0 some Frames have FramePort's shortcut in shortcuts.vdf (so the install skips the Steam restart) yet Steam answers Play with "Game configuration unavailable" (= `Steam_AppUpdateError_9`; console_log: `LaunchGameAction: launch error 9 <appid>`). Not reproducible on the dev Frame (same SteamOS build). Agent v42: `launch` returns `steam` = what Steam's console_log says about that launch (started / error + code / silent; the app logs it and offers Report a problem on an error) and `collect_diag` adds `steam_library` (real Steam dir behind ~/.steam, client beta, Steam start vs shortcuts.vdf write time, FramePort's entries per account) + `steam-console.txt`. Verified on the dev Frame 2026-10-04 (Play → `started` within ~1 s). The dev Frame runs Steam's **arm64 beta** client (`package/beta` = linux_arm64_beta_…): check whether reporters are on the stable client. Next: read those from a reporter's zip.
+**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). Cause unknown; agent v42/43 diagnostics: `launch` returns `steam` (started / error + code / silent from console_log), `collect_diag` adds `steam_library` (real Steam dir, beta, Steam start vs vdf write time, entries per account, devkit games) + `steam-console.txt` (incl. Steam's `logs/shortcuts.previous.txt` if present; steamclient.so has "LoadShortcuts: rejecting attempt to load shortcuts: invalid account ID"). **Fallback (agent v43):** when Play gets AppError_9 the agent registers the game through Steam's devkit interface (what Valve's Devkit Management Tool does, MIT: `devkit-1 steam://devkit-1/<~/.steam/steam.token>/create-shortcut?response=<file>&gameid=<id>&directory=~/devkit-game` written to ~/.steam/steam.pipe; answer file / `.error`; `~/devkit-game/<id>/launch.sh` = link to the game's launch.sh, `<id>-argv.json` ["launch.sh"] (relative to the folder), `<id>-settings.json` {steam_play 0, compat_tool ""}). Steam adds it live (no restart), picks its own appid (read back from shortcuts.vdf by DevkitGameID), shows it as a normal non-Steam game named "Devkit Game: <id>" (OpenVR 0, but VR works: owner-verified 2026-10-04), art copied to grid/<appid>*. 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 below 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).
+**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.

+# Meta XR Audio metadata lifetime
+
+FrameBridge automatically handles metadata retirement in the verified AArch64
+Meta XR Audio Wwise build (`e1619e7fb839badf0ea5ecc22d9f028d0b17c34d`). It requires
+the build ID and exact function prologues; other builds and 32-bit adapters are
+left unchanged. No additional patch switch or recipe entry is required.
+
+The SDK queues terminated metadata for deletion, then drains those queues before
+reading the current `AkAudioObjects` snapshot. In Batman: Arkham Shadow, that
+snapshot can still reference queued metadata during smoke-bomb playback. The
+audio thread subsequently clears its dirty flags at offset 8 through the stale
+pointer. A hardware watch captured this store in
+`OculusEndpointSink::ConsumeObjectExperimentalMetadata`, at library offset
+`0x2ced90`. Reallocated input tree nodes occupy the same 48-byte size class;
+the stale store corrupts their right pointer and the game crashes later.
+
+`native/adapter/audio_metadata.h` wraps the audio consumption boundary to make
+the current snapshot available to metadata cleanup. `audio_metadata_queue.h`
+retains queued objects still referenced by that snapshot, then reclaims them
+normally when the references disappear. It preserves the SDK's queue mutex,
+virtual deleting destructor, audio parameters and processing. There is no timed
+quarantine, replacement allocator, audio suppression or diagnostic memory arena.
+

+# FAQ
+
+## How should I lay out a game that has OBB files (an APK plus a data folder)?
+
+Give every game its own folder, put the APK in it, and put the game's data next to the APK in a folder named
+after the game's **package name** (the name the `.obb` files contain, e.g. `com.Armature.VR4`):
+
+```
+Games/                                  ← scan this folder (Add games → Scan a folder)
+├── Resident Evil 4/                    ← one folder per game (any name)
+│   ├── VR4.apk                         ← the APK (any file name)
+│   └── com.Armature.VR4/               ← the data folder: exactly the package name
+│       ├── main.203.com.Armature.VR4.obb
+│       └── patch.203.com.Armature.VR4.obb
+└── Beat Saber/
+    └── com.beatgames.beatsaber.apk     ← games without OBBs: just the APK
+```
+
+- **Data folder name:** the package name (`com.Armature.VR4` above), or `obb`. FramePort uses the first of the two
+  that exists and isn't empty.
+- **Everything in that folder is copied** to the game's `Android/obb/<package>/` on the Frame, subfolders included.
+  So games that ship raw data files instead of `.obb` files work the same way.
+- **One game per folder.** Several APKs in one folder count as one game; FramePort uses the first and keeps the others
+  as alternates.
+- **Scanning:** pick the folder that contains the game folders (`Games/` above) to add them all, or one game's folder
+  to add just that game. FramePort looks up to 5 levels deep.
+- **A single game:** Add games → Add an APK file… works with a lone APK too. Its data is found when the data folder sits next
+  to the APK, named as above.
+
+Not sure of the package name? Look at the OBB file names: `main.<version>.<package name>.obb`. Or add the APK
+first: the game's page shows the package name under **Details**.

+## Video of the headset view (surveyed 2026-10-05; used by the Live view tab)
+- `steamvr-v4l2cam.service` (user unit, part of gamescope-session.target, `Restart=always`) runs SteamVR's
+  `/opt/steamvr/bin/linuxarm64/v4l2cam --output=99`: it reads the compositor's "Headset View" (IVRHeadsetView) and
+  writes it to a v4l2loopback webcam named **"SteamVR"** (`/dev/video99`, 1920x1080 RGB24, advertised 30 fps, frames
+  arrive at the display rate). Nothing on the Frame reads it by default; idle it costs nothing, read ~0.2 core.
+  It shows what the wearer sees (SteamVR home, Steam's panels; a game's layers are expected but not yet seen in it).
+  Black and ~1 fps (one frame per ~1.0 s) while the headset sleeps (standby): a 30 fps stream then repeats each
+  frame in bursts, which looks like a stall in a player. Its size follows SteamVR's headset view (v4l2cam has no size
+  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
+  `.monitor` source carry what the headset plays; the Frame's ffmpeg has the `pulse` input and `aac`. Timestamps: pulse
+  uses the wall clock, v4l2 CLOCK_MONOTONIC → `-ts mono2abs` on the v4l2 input. Don't force
+  `-use_wallclock_as_timestamps` on the pulse input: it stamped bursts of AAC packets with one time.
+- Steam's own game recording / Remote Play / broadcast capture the **gamescope** PipeWire node (`CDesktopCapturePipeWire:
+  ... node path: gamescope`): with gamescope's `--backend openvr` that's only the flat Steam UI, not VR. Steam's arm64
+  `libvideo.so` encodes with x264 (vaapi/nvenc paths don't apply). No cast/spectator feature for the Frame's own VR view
+  exists in Steam's UI; the SteamVR web server (27062) has no mirror route.
+- Encoding: the Qualcomm encoder (`/dev/video23` qcom-iris-encoder, V4L2 M2M) doesn't work with the stock tools (ffmpeg
+  `h264_v4l2m2m` hangs, gst `v4l2h264enc` not-negotiated). ffmpeg + libx264 works: FramePort's live view
+  (`install/livestream.py`: `fps=30` before the scale, ultrafast/zerolatency, 3 threads, nice 10, fragmented MP4 on
+  stdout, + AAC 128k) measured 0.34 core at 720p / 0.56 at 1080p with a quiet picture (video only); expect ~1-1.4

+
+The Frame sends fragmented MP4 (H.264) on the stdout of one SSH command (`source_command`); a small HTTP server on
+127.0.0.1 relays it to a player page (`live_player.py`: Media Source Extensions, no plugin). Flet has no video control
+outside packaged builds, so the picture is shown in the browser, which also decodes it in hardware.
+
+The relay keeps the init segment (ftyp + moov) and the fragments since the last keyframe, so a viewer that opens later

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
