Buffering when playing 4K movies!

General Discussions
1

When Im trying to watch 4K movies it starts to buffering which is very annyoing and I think it shouldn’t buffer since I have a monster computer…
The CPU goes up to 100 % very often when im watching at TrueHD 7.1 audio and when I change audio from TrueHD 7.1 to AC3 5.1 my CPU works at 1-10 %.
BUT then it starts to buffer MUCH more then it does at TRUEHD 7.1…
I mean when I watch at TRUEHD 7.1 I can watch the whole movie with just some buffers but with AC3 5.1 I have to sit and wait for the buffering almost all the time…
I have tried with wired and wireless internet connection and there is no difference.
Can a NVIDIA Shield be a solution for this if there is no other fix?

I am watching the movies on this tv: 55 LED -TV Philips 55PUS8503/12 UHD Smart

And I have the plex media server on this computer:

How do you have the TV connected to the server? Wired or Wireless?

3

I was just gonna type that in the topic! I have the same issue with wired and wireless…

4

What are you using for a player? The app inside the TV?

5

I downloaded the plex app. I didn’t even know there was one in the TV and haven’t seen that one either. Maybe it was the wireless connection after all. I tried with cable now again and it seems to work right now atleast.

6

So what are you using to play the 4K file?

Plex is a serer/client application the Server streams the file to the client. So we need to know what type of client you are using to play the movie.

I am using the plex app that I downloaded on my android TV? Or what do you mean? And it still dosen’t work :smiley:
This app have so ■■■■■■■ many nice things that can make this app to the number 1 in the world for sure. But what I still dosen’t understand is that there is never any fixes for all this laggning ■■■■. And they always blame everything else then the app xD

I thought that I typed in the topic what I am using to play the 4K file? I have the files on this : WD My Book Duo 20TB and that is connected to the computer I typed about at the start of that thread!
And I have the plex media server on that computer to and I am trying to watch through the plex app on my 4K smart tv. .
I am going to try to copy over the 4K file to my SSD on the computer instead and see if that’s a problem.

After like 1 hour of loads of buffering into Mad Max furyroad 4K it stopped to buffer completely for like 15-30 mins and then it started again and kept going…
I don’t understand how it could go from buffering almost all the time to ZERO buffering for 15-30 mins.
And I tried to unplugg my external WD My Book Duo 20TB but it didn’t make any difference of the result.
So now im out of ideas, so please someone help meeeee.
I want this app to work so ■■■■■■■ bad…

Some quick checkbox questions:

  • What version of PMS are you using? Available here.
  • Plex server operating system (Windows/Linux/etc)? Running in a VM, Docker, etc?
  • Plex server and WD NAS both on wired 1 Gbps Ethernet?
  • What version of the Plex client are you using? Available here.

In the Plex client on the TV, is there a setting for Display Information? If so, turn it on (it exists on other Android TV devices).

On the movie pre-play screen, select the AC3 audio stream and disable subtitles, including forced, if enabled.

Play Guardians of the Galaxy (the movie mentioned in your original post).

During playback, pull up the on-screen controls (pause the movie, etc).

Look in the upper left corner of the screen. It should say if the video & audio are direct playing, direct streaming, or transcoding.

What does it say for both video & audio. If transcoding, what reason?

PMS = 1.15.6.1079-78232c603

I am using windows 10 bought version and I don’t really know what you mean with Running in a VM, Docker etc? Im not really that good on this things so explain little more what you mean with that please!
Plex server and WD NAS both on wired 1 gbps ethernet?
I am using wire to both the PMS computer and the 4K smart TV and I got 1000/1000 mbit internet. Or did you mean something else?
This is the version of the smart tv I use: 7.16.1.10610

I selected AC3 audio and disabled subs and then it worked with no bufferings at all. But how can I see if it Direct play for both video and audio? I can only see player: ExoPlayer V2 and resolution: 3840x2160 and under that it just says: Direct Play in the top left corner.

And now when I tried with subtitle that I have added by myself as a srt file it starts to buffer… But it still says Direct Play in the top left corner…
