+# OBS end-to-end validation — 25 October 2026
+
+**Passthrough: yes.** Real room pixels behind SteamVR panels appeared in the
+live `/dev/video99` mirror, the saved OBS recording, and a decoded frame at
+four seconds in a production MP4. The Frame was safely woken with
+`vrcmd --handlewakeup`; no camera, power or compositor settings were changed.
+This establishes the checked SteamVR mirror, not every game/mode or Steam's
+own clips. Treat recordings as potentially showing the room.
+
+## Environment and provenance
+
+- Host: lxso2, Linux x86_64. Real OBS 30.0.2 in disposable Ubuntu 24.04/Xvfb,
+  using software llvmpipe rendering and the Media Source `ffmpeg_source`.
+- Frame: SteamOS 0.5.6, build `20261022.6153909`, SteamVR 2.18.2, reachable
+  with the existing `ssh frame` connection. Hardware use was serialized with
+  coordinator mppkd9qczt through `/tmp/frame-test.lock` and a unique owner.
+- Released v0.4.30 AppImage SHA-256:
+  `b1335bb06130f2cce64a0dd40a8cb60a52c68effc258dc4bc35f8c40c822d5bb`.
+  The long recording started through this app's actual Electron IPC, Python
+  helper and SSH stream. Robustness checks then used that released runtime
+  with the final changed resources and repacked `app.asar`; this was not a
+  newly built AppImage. No OBS plugin or host FFmpeg is required by the app.
+- Windows release ZIP SHA-256:
+  `a393cc1653f14f162b4a3e56803f7fe9bea7b04904d18577b0b2d7d7c2d95b03`.
+  Checked against release SHA256SUMS; bundled Python 3.12.14.
+
+Machine-readable measurements and the manual stimulus/analysis programs are
+in [obs-validation-2026-10-25/](obs-validation-2026-10-25/).
+Room images and videos remain private under `/tmp/obs-aacapv3evh` on lxso2;
+only their hashes are committed in `private-artifacts.json`.
+
+## Recording, sound, sync and latency
+
+| Check | Measured result | What it establishes |
+| --- | --- | --- |
+| Real OBS recording | 187.367 s; 15,784,412 bytes; H.264 1280×720 at 30 fps; 5,621 decoded video frames; AAC 48 kHz stereo | More than three minutes through the packaged Linux path |
+| OBS dropped frames | 0 encoder skips; 90 render lag/stall frames, approximately 1.6% of recording frames | The software-rendered host was not lossless; this is not a hardware-rendered performance benchmark |
+| Audio | 1 kHz stimulus; FFT peak 996.094 Hz at 11.719 Hz bin resolution; peak −13.207 dBFS; 0 clipped samples; measured harmonic energy −81.32 dB relative to fundamental | Non-silent, no numerical clipping or large harmonic distortion in the checked tone; no listening or real-game quality verdict |
+| Baseline A/V | Audio leads video by median 426.67 ms; range 360–426.67 ms across 36 pulses | Default OBS setup needs sync checking; not suitable for a claim of automatic accurate sync |
+| Live image latency | 1,431.4 ms, n=1; clock exchange RTT 3.409 ms; screenshot polling about 20–35 ms | Overlay submission to OBS source screenshot, not physical headset motion-to-photon latency |
+| Production MP4 | 5.121 s; 1920×1080, 30 fps, 153 video frames; AAC stereo; request to saved result 7.435 s | A separate production recorder saved room passthrough pixels too |
+
+The manual stimulus places an owned black/white OpenVR marker over the mirror
+and plays a 200 ms, 1 kHz tone every five seconds through the Frame's default
+output. `pa_simple_get_latency` estimates when the submitted samples play;
+marker submission is aligned to that estimate. This measures software output,
+not an externally measured loudspeaker/physical-display event. Most submission
+jitter was below 0.2 ms; compositor timing and the 30 fps/10 ms analysis grids
+still limit precision. FFmpeg decodes both tracks; the analysis detects marker
+edges and groups AAC pre-echo onsets within 100 ms.
+
+A separate initial +400 ms OBS Sync Offset trial left 83.33 ms of audio lead.
+Changing the offset during an already active source from 0 to +367 ms did not
+improve that run (366.67 ms before, 370 ms after). Do not assume a universal
+offset or that a live setting change has taken effect: reopen the source and
+verify another recording. Three subsequent fresh-source trials, setting the offset **before activating**
+the Media Source, measured 480 ms audio lead at 0 ms, 70 ms lead at +400 ms,
+and **0 ms at +480 ms** across three pulses (30 fps video and 10 ms audio
+analysis resolution). This proves a setup-specific workaround, not a universal
+default. See `calibration-initial.json`. Full trial measurements are retained. Zero OBS
+buffering caused missing/distorted sound and was rejected. Zero mux delay
+and alternate timestamp experiments did not improve latency and were not
+merged. The default capture/encoding settings remain unchanged.
+
+## Robustness and fixes
+
+| Failure or scenario | Fix / result | Proof |
+| --- | --- | --- |
+| Stop during asynchronous Python discovery could still launch later | Cancel the pending generation; expose Stop while starting | Controller regression test |
+| Late stderr containing an earlier ready message changed stopping back to running | Only accept ready while starting; ignore stale child events | Original released block reproduced in `race-before.json`; controller regression |
+| A non-responsive SSH process defeated timeout termination | Bounded terminate/wait then kill; SSH connection/keepalive bounds | Real SSH child deliberately stopped with SIGSTOP; clear UI failure in 15.009 s including 5 s forced cleanup; both processes gone |
+| Timeout with the app's stdin still open aborted Python at shutdown | Read the control descriptor directly, avoiding a blocked buffered-stdin daemon lock | Previously reproduced fatal shutdown; final real stall shows `The Frame OBS video stopped for 10 seconds`; subprocess regression holds stdin open |
+| Three Start/Stop cycles | First packets 0.890 / 0.701 / 0.709 s; Stop to idle 61.7 / 52.7 / 53.0 ms | Final patched packaged runtime, ports 15101–15103, `robustness.json` |
+| Restart after stall | First packet 0.691 s | Same runtime and real Frame |
+| Quit while streaming | No surviving helper at 2.021 s | Same runtime; final audit found no test FFmpeg/stimulus process |
+| Port 15099 occupied | App now offers a validated alternate port and matching copyable URL | OBS occupied 15099 while real packets arrived on alternate ports; UDP cannot identify or guarantee the receiver |
+| OBS before/after Start; receiver restarts | Live decoding verified, including recreated sources while relay stays active; an already-open stalled receiver may need hide/show or properties OK | Documented recovery, not automatic OBS control |
+| Standby/wake | Safe wake changed a blank mirror to visible room/panels | Private mirror and saved recordings |
+
+A forced SSH stall tests the transport failure and error/cleanup behavior.
+It does **not** prove real Wi-Fi loss or full headset suspend/resume. No physical
+network interface was disabled and no headset reset was performed. There is
+no automatic reconnect: restore connectivity and press Start. Valid blank
+standby frames do not trigger a packet timeout.
+
+## Windows and macOS
+
+**Windows controls remain hidden.** A disposable Windows 11 VM ran the final
+helper using the released app's bundled Python and a native executable SSH
+fixture. It stayed alive for three seconds without a UDP receiver, then sent
+1,316-byte packets when a receiver opened. Closing its control pipe returned
+exit 0 with no surviving SSH child (`windows-pipe.json`; stop measured below
+the VM timer's resolution in the final run). The helper hides the SSH console
+and tolerates Winsock's delayed UDP receiver-unreachable error.
+
+The real-headset Windows attempt delivered zero packets through a temporary
+host SSH bridge. Native Windows OBS, direct Windows-to-Frame SSH, firewall
+behavior and packaged app Start/Stop have therefore not passed end to end.
+No local FFmpeg was installed; encoding belongs on the Frame. No firewall
+exception, headset authorized key, or Windows scheduled task was installed.
+
+**macOS:** no physical Mac or macOS VM was available. Python tests and the
+five controller lifecycle tests run in the macOS CI matrix; these cannot
+establish capture performance, audio quality, packaged launch or OBS behavior
+on a physical Mac.
+
+## Validation and remaining limits
+
+Local suite: **1,514 Python tests passed, 16 skipped**, 46 app tests and 18
+site tests passed. The latest helper additionally passed all 11 focused OBS
+tests; the controller passed all five focused lifecycle tests. Cross-platform
+CI results belong to the linked PR, not these host measurements.
+
+Still unverified: perceptual listening, real-game audio routing, accurate
+default A/V sync, broad latency/performance across hosts, hours-long sessions,
+physical Wi-Fi drop/full suspend recovery, physical macOS and native Windows
+OBS. The app/docs now explain copyable URL/format, receiver recovery, port
+selection, passthrough privacy and OBS Virtual Camera's video-only limit.
+The Discord guide provides the corresponding audio-sharing choices.
+
+Cleanup completed: Steam and vrcompositor remained running, battery 98%,
+no test FFmpeg/stimulus process remained, UDP ports 15099/15101/15102/15103/15105
+were bindable, task guest SSH config and the temporary bridge were removed,
+and the owned headset lock was released. The disposable Windows VM was
+stopped with its disk retained. See `cleanup.json`.
