CPU rate will jump to 100% at times while watching a recorded shows. It has only been doing it a short time not sure if it started with the last update but it seams to have.

Github-63 commented 3 years ago

Windows 10 Version 1.31.1.2262-74fdc6b7 Version 1.22.3.4392

Steps to reproduce

Have the Plex client running and watching a recorded show. CPU much higher than before even when Plex is not recording or displaying a show. But at times it drops back down into the 40s but what I found interesting is Plex does not show any or very little CPU and all the processing being done by QT QTwebengineprocess.

Current behavior

CPU high and computer is slow to respond. At times the picture will freeze up or not display but the sound starts. When trying to pause the show it takes a long time for the show to respond to the pause or the jump forward or backward buttons or any of the controls.

Expected behavior

Able to watch a recorded show and be able to fast forward, pause, view the show or stop it when the buttons are pressed.

I see a new version of the server out there Version 1.22.3.4523. Will install it tomorrow and test. If that does not work is there a way to go back a version on the Desktop client?

Github-63 commented 3 years ago

Upgraded the server same issue. - Is anyone looking a at these. Can someone at least say they have seen this?

Github-63 commented 3 years ago

I have the plex for life account and I think once it the software starts working again I don't plan to put on any patches since there has been on more that one occasions that Plex did not work well after installing the updates. And now with the software almost unusable I don't see where anyone is even looking at issues. If the issue is not clear or you need more information ask me I will clarify or add more to this if that will help.

Plex Media Server Logs_2021-05-19_12-52-33.zip

mseeley commented 3 years ago

Hi @Github-63, please restart the app, observe the unexpectedly high CPU usage for several minutes, quit the app, then provide the most recent of each of these files:

%LOCALAPPDATA%\Plex\Logs\Plex.log
%LOCALAPPDATA%\Plex\Plex Media Server\Logs\Plex Media Server.log

Able to watch a recorded show and be able to fast forward, pause, view the show or stop it when the buttons are pressed.

Are you referring to shows recorded from a Plex DVR? If so, is it only DVR recorded content that is causing problems?

Plex.log Plex Media Server.log

Github-63 commented 3 years ago

99% of what we watch is what is recorded from the DVR. I have not tested the other. it does seem like the longer the app stay up the worse it gets. Not as much by CPU% but in time to respond. we had been watching the National parks show from PBS as one of the last things during this log. After stopping the show I tried to start it up again and it took a long time for it to finally start playing. I leave task manager up and when switch to it it will show 100% cpu then drop back down to 40-60%. If i shutdown the Plex client the cpu will drop to about 3% even with the Plex server running. Starting the plex client up it jumps up to about 40% even when nothing is playing. That is what i was trying to show with the pictures on the first post. Plex server running nothing recording CPU 3%. The pictures were named with a description of what was happening but it appears that the names don't show up but they had names like "Plex desktop not running, Plex server running nothing recording.JPG" and "Plex desktop, display list of recorded shows Plex server running nothing recording.JPG"

The issue was already occurring about 10:50 pm when i tried to skip 30sec forward it started just freezing up. Even the spinning circle was not spinning.

Hi Github-63. I've carefully reviewed the logs you provided. I've also watched several hours of recorded and live DVR content.

I've been unable to reproduce massive CPU, GPU, or memory usage. I see the user interface performance less smooth during playback though I haven't witnessed it breaking down as you have.

With nothing playing our a CPU is around 4% for me. GPU can still 50-60% if the Activity icon in the app's header is animating. We're aware of the high cost animation has on the UI and have intentions to optimize.

If you're using this as a living room TV substitute please try our HTPC app: https://forums.plex.tv/t/introducing-plex-htpc/703075. It shares much code with the app you're testing here, it may have the same issue. Although perhaps the UI reduces overhead.

That's the best feedback I can provide on the situation you're facing.

kanetse commented 3 years ago

I have seen this problem as well, but for me, it is not limited to Plex-DVR recordings. I see it appear on everything, sometimes even if I just leave Plex running in the background. I can tell because the UI becomes very sluggish at that point (whether in playback or even menus after playback is stopped), and like @Github-63 , Windows task manager will show that QT QTwebengineprocess is consuming a high amount of CPU.

It only started occurring under the most recent release of the Plex Media Player, 1.31.1.2262-74fdc6b7. Closing the program and reopening it fixes the problem. It doesn't happen every time, but I run Plex enough that I encounter it daily.

The next time it happens, I will generate some logs following @mseeley's instructions and attach them here.

Github-63 commented 3 years ago

restarting plex client does help but it does not take long before it is sluggish and not responding. Is there a way i can get a copy of the previous version. Currently i am running Plex-1.31.1.2262-74fdc6b7 and i did not have this issue before installing it.

Github-63 commented 3 years ago

HTPC app did not work so well either. I could back up but not forward any of the recordings i tried with it.

Github-63 commented 3 years ago

It appears that the problem has been solved. I have been using "Plex for windows" that just shows the name plex when running. I installed Plex media player Windows 7 SP1 or later (64-bit only). 2.58.0.1076-38e019d and it worked just fine. When i tested Plex for windows it now works fine too. So one of the common files use between the 2 appear to be the issue. Later on to I may uninstall PMP and see if PFW still works. IF it does i will uninstall it and reinstall it and see if the issue comes back which I would assume it would.

Github-63 commented 3 years ago

When I just had the Plex for windows installed I was having problems.. Now I have both Plex for windows and Plex media player. The problems went away after installing plex media player. I still have PMP installed and have been using both off and on but Plex for Windows more and have not had any trouble since.

Hi @Github-63. Going to close this out as it sounds like the apps are working better for you.
