TV always starts delayed on one client (1 Viewer)

[Marcus Venturi]

The strange thing is that it happens only after a longer standby. If look TV, go to stand by and resume immediately, then everything is OK.
If I go to standby for a few minutes, then resume and start TV the problem occurs.

All PCs use Windows Defender. On the server and the clients I have excluded the "C:\Program Files (x86)\Team MediaPortal\" from Windows Defender. On the server side I have also excluded the RAM-disk drive for the timeshift.

All PCs use the Windows firewall with default settings.

[2016-12-23 07:28:35,463] [Log ] [PS StandbyWakeup] [DEBUG] - PS: Cannot signal client activity to remote TvServer: Die Verbindung mit dem Remoteserver kann nicht hergestellt werden.

The stream is playing (at least the sound), but PS (PowerScheduler?) can not connect to the Server?

It might be an idea to have Task Manager open with MP in windowed mode (after wake from standby), then start TV and check if there is a process using a lot of CPU ?

This is really strange, the most CPU was consumed by the "Anitmalware Service Executable" (aka Defender).
I had excluded the "C:\Program Files (x86)\Team MediaPortal" and additionally the "MediaPortal.exe".
On a client there is no timeshift stuff to exclude.

I will try again with Defender turned off. Is there something additionally I should exclude on a client?

I always exclude "C:\ProgramData\Team MediaPortal" and "C:\Program Files (x86)\LAV Filters" as well.

But your 'HTPC' system is fairly powerful so I would not expect Windows Defender to cause the sort of delays you are getting, unless something strange is going on.

If you wake up the PC and then wait a few minutes before starting TV, does the problem still happen?

 

[Marcus Venturi]

Turned Defender off for testing. Delay was still there . "MediaPortal.exe" was the task with the most CPU (4.6%). While this happens MediaPortal is completely blocked. I will repeat the test later again to get logs...

I will test that...

Resumed the HTPC this morning and waited 5 minutes on the desktop before starting TV. Delay is still there.

What is also very strange: If I suspend the PC then and resume immediately, everything works fine. Only if the PC was suspended for a longer time the delay occurs.

Hmmm, this result is quite interesting.

From looking at the code, one possibility is that the delay is related to a plugin handling the playback started event. So, are you able to reproduce the problem with Watchdog option 1 (all 3rd party plugins disabled)? Considering the PowerScheduler message that Owlsroost saw, it may also be useful to test with the PS plugin disabled.

What is also very strange: If I suspend the PC then and resume immediately, everything works fine. Only if the PC was suspended for a longer time the delay occurs.

This suggests that the problem may be related to server connection loss or lower power state which is only attained/reached when the PC is suspended for at least X seconds/minutes.

Yes I used option 1. Will try disabling PowerScheduler.

Maybe I should change power state settings in the BIOS.

 

[Marcus Venturi]

I turned off PowerScheduler. I checked that IPV6 is definitely off on server and client. I completely turned off Windows Defender on the client.
The delay was a bit shorter this morning, but it's still there.The Problem only happens if the client is off for a few hours (not minutes).

Okay. Please try temporarily disabling all other 3rd party plugins as well. Any one of them could introduce the delay when handling the on playback start event.

Also I see you're still using RTSP.
Did you try UNC paths instead of RTSP as I previously suggested?

Another idea would be to try UNC paths (SMB shares) instead of RTSP:

In most of my other logs I was using the option 1 of the Watchdog tool. As the error also happened then, I assume it's not a 3rd party tool, as that option disables 3rd Party plugins. Is that correct?

Thank you for the reminder to the UNC stuff. I forgot to check that. Will do this ASAP.
