Standby/Sleep During Playback

[mvallevand]

I did lots of testing with pwrtest and it only shows the ES_SYSTEM_REQUIRED changes so the tools isn't as useful as I hoped it would be. During my testing machine would sleep if just ES_SYSTEM_REQUIRED was set so it is no just you.

Having NextPVR go to sleep after playback was almost as annoying though.

Thanks for confirming ES_SYSTEM_REQUIRED alone doesn't prevent sleep anymore. Glad it's not just me.

Even if sub added ES_CONTINUOUS it's not easy to know when to clear it after playback. For recordings he added BlockShutdownForExtraSecondsAfterRecording. What if playing is paused so playing is temporarily stopped?

I don't know the answers.

That shutdown is handled by the tray app so won't help, it doesn't know about playback.

During pause you can tell us, if power management logging is enabled, do you see the PowerManagement PreventStandby messages. I expect if the whole file is sent you could have issues if your try and rewind.

Basically using a server with aggressive sleep behaviour is a bad choice when you also want to use remote clients.

One ugly hack that would be easy is a config file keyword to simply throw in ES_DISPLAY_REQUIRED with ES_SYSTEM_REQUIRED (default false).

Code:

<WorkAroundWindows11IdleTimerBug>true</WorkAroundWindows11IdleTimerBug>

This would work as it did on Windows 10 with the only caveat being the display also remains on. Note that ES_DISPLAY_REQUIRED alone on Windows 11 also doesn't prevent sleep unlike Windows 10. My HTPC TV is off anyways when playing remotely so no difference.

This can be tested in the script from post #53 by uncommenting the success line instead of the fail line.

Code:

#$ste::SetThreadExecutionState($ES_SYSTEM_REQUIRED -bor $ES_DISPLAY_REQUIRED) # success
$ste::SetThreadExecutionState($ES_SYSTEM_REQUIRED) # Win10 success, Win11 Fail

Interesting observations:

On Windows 11 ES_DISPLAY_REQUIRED alone does not work.
While playing back remotely on kodi, pwrtest.exe /es revealed that kodi is making repeated requests with ES_DISPLAY_REQUIRED and ES_SYSTEM_REQUIRED together even though documentation says ES_DISPLAY_REQUIRED alone should be used.
