 ## Open the app
 
-**Optional: open at login.** In the installed desktop app, choose **Frame → Open at Login**. It is off by default. When on, a login launch starts in the tray or menu bar if that control is available; click its icon to open the window, or use its **Quit Frame Control** menu item. Closing the window keeps the app in the tray while this option is on. Turn the same menu option off to remove its OS login item. On Linux this creates or removes only Frame Control's own file in `~/.config/autostart/` (or `$XDG_CONFIG_HOME/autostart/`). If the desktop has no working tray, the window opens at login instead. A source checkout does not offer this setting.
-
 - **macOS:** open the `.dmg`, drag **Frame Control** to **Applications**, then
   open it from Applications. For the Gatekeeper warning, use the macOS steps
   above. Allow local network access and control of Terminal when prompted.

-# OBS relay and MP4 follow-up, 25 October 2026 UTC
-
-This check used a Linux x86-64 host (`lxso2`) and the real Frame running
-SteamOS 0.5.6, build `20261022.6153909`. The host reached `ssh frame`. Before
-device work, the task atomically acquired `/tmp/frame-test.lock`, wrote its
-owner marker, and after cleanup removed only that marker and its lock. Battery
-was 99–100%; SteamVR 2.18.2 reported `activity_level: 3` (standby). Steam and
-SteamVR were left running. No passthrough session or game was started.
-
-The production `scripts/obs-headset-source.py` relay reached its first local
-UDP packet in 0.65–1.15 seconds across several runs. A 12-second wall-clock
-capture of its MPEG-TS packets contained 325 H.264 frames at 1280×720,
-spanning 10.83 seconds of video timestamps: 30.0 fps. All 324 adjacent frame
-intervals were 33.333–33.334 ms, with none over 50 ms. The 826 captured TS
-packets had zero sync-byte, transport-error-indicator, or per-PID continuity
-errors. Six final TS packets arrived after the receiver's 12-second cutoff and
-were not included in those counts. Static standby pixels cannot establish
-whether a moving game would drop frames.
-
-After the fix, the `--height 1080 --fps 60 --no-audio` fallback reached its
-first packet in 0.597 seconds. An eight-second wall-clock capture contained
-447 H.264 frames at 1920×1080 over 7.45 seconds of video timestamps: 60.0 fps.
-All frame intervals were 16.666–16.667 ms, none over 25 ms, and its 756 TS
-packets had zero continuity or transport-error-indicator errors. It had no
-audio stream, as requested. The helper exited 0 on Stop, and the owned lock
-was released.
-
-The stream also contained 48 kHz stereo AAC. A 440 Hz synthetic tone played
-through the Frame's default speaker output with real-time pacing appeared in
-the capture for about 0.89 seconds; decoded audio had a -21.0 dB peak. This
-proves an audio signal reached the output monitor and OBS transport. It does
-not prove audible monitoring, real game audio, or audio/video sync: there was
-no simultaneous visible marker to compare with the tone.
-
-The production MP4 recording commands were run separately for six seconds,
-then Stop, remux, and copy to the host completed. Stop returned after 7.27
-seconds from Start, including six seconds of recording; the remote ffmpeg
-exited 0. The copied 36,929-byte MP4 contained 188 H.264 frames at 1920×1080
-and 30 fps (6.266 seconds), plus 281 AAC packets (5.994 seconds). One decoded
-frame at two seconds had a single color, RGB `(22, 27, 53)`, across all
-2,073,600 pixels. The test's remote files were removed; the host copy stayed
-under `/tmp` for inspection.
-
-The relay previously returned an error when the app deliberately closed its
-control pipe, because its SSH child commonly exits 255 after termination.
-The same test reproduced this (`helper_exit: 1`) on the real Frame. The follow-up
-fix recognizes deliberate Stop and adds bounded startup and stall timeouts,
-with fake-SSH regression tests. A new locked real-Frame check after the fix
-received its first 1,316-byte UDP datagram in 0.697 seconds and returned
-`helper_exit_after_stop: 0` after closing the app control pipe. The longer
-transport and MP4 measurements above were taken before the code change; the
-fix does not alter codecs or capture commands.
-
-Prior [OBS 30 Media Source evidence](obs-media-source-real-2026-10-25.md)
-records a real Frame stream in OBS on Linux. This follow-up measured the relay
-with an FFmpeg receiver; OBS itself was not relaunched. Windows and macOS
-application paths, wearer-visible image latency, real game sound, audible
-playback, perceptual A/V sync, and active passthrough pixels remain unverified.

-## Known issue: game audio in OBS
-
-A Frame owner [reported](https://x.com/AzizahStellazio/status/2114147449468293171)
-that OBS **Game Capture / Application Audio Capture** can lose game audio when
-the headset turns on. OBS support attributed this to Valve/SteamVR. Frame
-Control cannot change that game-audio routing. If it happens, use Frame
-Control's **Start OBS source** and OBS **Media Source** steps above to capture
-the headset view and its output audio. You can also try OBS **Desktop Audio
-Capture** for the computer's output, then check its meter and a short test
-recording before you stream. Do not leave two active sources for the same audio
-unless you want duplicate sound.
-
-The real Frame/OBS check above proved that a synthetic tone from the Frame's
-output reached the Media Source recording. It did **not** use a running game,
-listen to the audio, reproduce the reported Game Capture failure, or measure
-audio/video sync. Real game audio while the headset is awake remains unverified.
