[confirm] Powersaving kicks in if videos run too long (1 Viewer)

[Flaamwing]

Windows power saving has turned off my monitors and TV while I'm in the middle of watching a video. I suggest, and have tested, the following patch. I ask that you please implement it or a variant to let windows know that something is happening, so it doesn't stop the system.

Thanks

have not tried this out yet with MP. But i had the problem with a friends app. (believe but havent checked that screen stays on in older versions)
but for win 7: SC_MONITORPOWER in Windows 7?

agree that SetThreadExecutionState() would be nice

Maybe my problem is related to this. After watching a video, the monitor/beamer instantly looses the video signal at the end and goes into standby. A click on the remote brings the signal back but it's really annoying.

I am not at home to check but IIRC the issue with that code is it will not work under XP (Win32 power code changed a lot between XP and Vista)

Do you have the PowerScheduler plugin enabled? I think you need to have this enabled to prevent standby

That sounds like it keeps the screen away for the time Video is running, but the counter is not reset at the end so windows turns screen off.

=> sounds like a different problem. But i think with Flaamwings code it would be solved as well.

with that code is it will not work under XP

i disagree. would work for win 2000 and up

SetThreadExecutionState:
Minimum supported client:	Windows 2000 Professional

I think it was more the integration into the Powerscheduler code which for XP still intercepts requests to standby and then tries to block them. I seem to recall getting some very odd unexpected results combining this (good code) with the XP powerscheduler code

Also as I said above, I belive the MP design is for power to be controlled via PowerScheduler. I guess some peope might want it to time out and go to sleep if they fall asleep whilst watching TV (indeed I would imagine this code will break the plugin which acts as a sleep timer)

Can you please post this in the "submit patches" section?
That would be the right way to get patches evaluated by our devs.

 

[Flaamwing]

Checking back on it, and just realized I should have mentioned that I did so after your suggestion. Can follow it here for any interested: https://forum.team-mediaportal.com/...event-powersaving-while-watching-video-79164/

I have this issue as well. I have monitor blanking at 5 minutes. If i do not touch my keyboard/mouse for the last 5 or more minutes of a video, it will immediately blank when it is finished.

Just sent a reminder to our devs to take care about the patch.
