Power Scheduler Exception / MP Fails to prevent Standby (1 Viewer)

[nyt]

Running without the TV server, I get the following error when PowerScheduler tries to prevent standby. Is power scheduler dependent on the tv server functionality?

The problem I'm seeing is that MediaPortal goes to sleep during playback. I do not see anywhere in the source to prevent this when I looked through.

I see a function PreventMonitorPowerdown in Win32API but it is never called.

Judging by the log output of "PowerScheduler: Keep server alive" the singleseat code there isn't run.

Also, all of this code seems to rely on RemotePowerControl, which connects to localhost on 31457. However, the only place I see a bind for that is in TvEngine.PowerScheduler.PowerScheduler (TvEngine3\TVLibrary\Plugins\PowerScheduler). This code will never work without TVservice.

Is there another way that MP tries to keep itself from being suspended that may not be working, or is that it?

 

[arion_p]

As it is right now, MP can only use internal PowerSchedulerClient plugin to manage power state. Windows' power settings should be disabled. I know that in the past there have been attempts to use Windows' power settings to suspend the system, but from what I read there have always been issues with it. That is why it was abandoned and PowerScheduler plugin was created. I have not seen the code before PS plugin so I do not know if there was something wrong with it that caused the issues. But with PS plugin instead of Windows power settings it works regardless of TV Server being installed or not.

Still there is an issue here that PS client plugin unnecessarily logs these errors and that should be fixed (actually it is quite easy)

PS Client isn't actually putting the server into standby. I just have a log full of exceptions, and the htpc never goes to sleep. So, MP doesn't handle windows power events, and it won't put itself to sleep. PS is set to enabled, and I had the timer set to 30m. No joy.

So, I see two problems with MP and sleep issues.

1) MP does not prevent standby/sleep/power events during playback. Is there any reason why MP doesn't do this?
2) power scheduler plugin is split so that it's useless if you're not using TVService.

Hi,
I'll jump onto this & see if I can confirm it within some days.

Hi,
Bug now confirmed & added to Mantis.
Thx for testing!

MP doesn't support currently letting Windows power management to be used. Missing feature.

 

[Paranoid Delusion]

If this a singleseat setup with no tvserver, then cannot see why you do not use windows settings for power control, same as I do with a singleseat "ForTheRecord" powered tv service, this does not require any of the powerscheduler plugins to be enabled.

Also just as a side note, both mysleeptimer and Sleepcontrol plugins allow timed shutdown after media has stopped playing, ie my sleeptimer setting is 5 minutes, so when activated it will close MP when video\playlist finished or whatever you set in config after 5 minutes inactivity, and then the M$ power settings kick in, again mine set at 5 minutes then suspend.
