OBS V32+ startup dialog

[iandol]

The latest V32 release of OBS removed the --disable-shutdown-check or changed the safe-mode trigger.

obsproject/obs-studio#12650

THis is not an OBS bug, they are just being more strict for reporting already existing problems, but it breaks background use. One solution is to manually delete the watchdog file OBS creates, thus stopping a dialog at start. Another is solve why shutdown of OBS is unclean and fix the root problem.

I found the file, we can mod the serivce to do something like:

[Service]
Type=simple
# to find some tools installed by pixi or brew etc
Environment=PATH=%h/.pixi/bin:%h/.local/bin:%h/bin:/usr/local/MATLAB/R2025a/bin:/home/linuxbrew/.linuxbrew/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin
ExecStartPre=-rm -rf ~/.var/app/com.obsproject.Studio/config/obs-studio/.sentinel
ExecStartPre=/usr/bin/sleep 15s
ExecStart=/usr/bin/flatpak run com.obsproject.Studio --startstreaming --disable-shutdown-check --minimize-to-tray
ExecStop=/usr/bin/flatpak kill com.obsproject.Studio
ExecStopPost=-rm -rf ~/.var/app/com.obsproject.Studio/config/obs-studio/.sentinel
Restart=always
RestartSec=15

It deletes the .sentinel folder both before and after obs starts/stops. Need to test it...

Hi, regarding this issue, I think what we can try is:

• Add a new port to cogmoteGO to control the start or stop of obs
• Create a shutdown.service to send a message to cogmoteGO to clean up obs before shutdown

In this solution, I assume that most of the reasons for entering OBS safe mode are caused by our powering on and off.

rm -rf ~/.var/app/com.obsproject.Studio/config/obs-studio/.sentinel works so far. I'm not sure if just stopping/starting obs alone will help as there is another really annoying bug where we need to manually restart mediamtx and obs together at first boot. mediamtx also has an API: https://mediamtx.org/docs/references/control-api

Anyway this is fixed with the modified service for the moment until cogmoteGO gets some more functions...

I hope to improve our startup and shutdown processes. During startup, first start mediamtx, then start obs. Then, confirm the running status of mediamtx through cogmoteGO, and when mediamtx is running stably, control cogmoteGO through cogmoteGO to start streaming.

My Linux test environment hasn't been fully set up yet, and I might need a week to get this done.

At the same time, I have already made some attempts on Windows:
