Standby/Sleep During Playback

[mvallevand]

In another test it did partially work (no prevent standby until the recording ended though and then the don't continue to the end.

Code:

2025-03-02 14:31:01.230    [DEBUG][11]    PowerManagement AllowSleep
2025-03-02 14:31:01.230    [DEBUG][11]    No longer active

but they stop being sent at that point even though it was streaming.

It's possible it had already sent the whole file by that point, so was no longer actively in the loop where PreventStandby is called.

That's a good bet there was a burst here after the last standby

2025-03-02 14:33:54.113 [DEBUG][55] Sent total of 3384000 bytes

with minor transfers every 2 seconds after that until the end.

I did another test and nothing is logged while paused either.

I guess as long as the flag is set it doesn't matter what is logged.

From memory it only does it every minute, so you need to have been streaming for at least a minute. (ie, not reached the end of a small file, or skipped to effectively start the timer again)

[mvallevand]

That might explain something. After the in-progress ends pvr.nextpvr tries to read more data (it still thinks it is in-progress ) so it will never reach one minute after an open.

I've made a change so the lastKeepAwake time is a static, so that the skipping / rerequesting won't reset the timer.

fla, if your scenario was using this method for streaming, and you set <LogPowerManagement>true</LogPowerManagement> you should see regular "PowerManagement PreventStandby..." messages in nrecord.log

Just saw this, rough day health-wise... Sounds like the two gurus have found something already. I've got my LogPowerManagement turned on and willing to test.

[gEd]

I was reminded about this thread when UIdroid completely hung earlier today when watching a recording. I realised that this was because the PC had gone to sleep (because it was during the part of the day when it's allowed to sleep if it want's).

After setting <LogPowerManagement>true</LogPowerManagement> (NOT True I discovered....) and updating to the latest pre-release (I was on the december release before) now shows "PowerManagement StayAwake" when playing back via UIDroid.

Cool!

Thanks @gEd I didn't know about prerelease builds. I installed Version: 7.0.1.250421 and played a recording over LAN from kodi and the nrecord.log on the Win11 server does indeed show "[DEBUG][19] PowerManagement PreventStandby..." every minute.

The bad news is if I run "powercfg /requests" on the Win11 server (Administrator Command Prompt) it always shows "None" for all categories. Do you see actual requests on the server?
