Hi Team,
When I attempt to playback a 4K movie from my library via the Plex for Android TV app I receive an error stating my connection to the server is not fast enough, then the client will play the video pausing every 3-10 seconds to buffer.
Bitrate of movie does not appear to be cause as I have tested files 28Mbps - 40Mbps which all fail.
(Movies with the same bitrates except at 1080p play back without this issue).
TV is wired (gigabit)
Server is wired, dual Xeon with copious amounts of RAM so server power shouldn’t be an issue.
4K tv shows do not appear to be affected, and playback without issue.
Any suggestions?
Anyone else?
Any ideas on how to solve?
Can you recreate the problem? Then provide the xml for one of these files that don’t play. Also please provide the server and app log showing the start of playback for this same file.
@MovieFan.Plex I will run a test when I get home tonight!
Attached logs and XML
I am going to assume it has something to do with this?

I’m not familiar with your TV but there are 2 things that I see that could cause the transcoding. Your TV has to be able to support BOTH of these, or it will transcode.
- 10 bit HEVC
- 7.1 TrueHD (either be able to down-sample or pass-through) (if pass-through, your AVR must support TrueHD 7.1)
I need the android app log from your TV to see what it says it supports.
New files!
Because I took forever to reply.
Everything took place at appx 5:23/24PM (17:23/24)
Sorry about that. Thanks for the bump.
Do you have 2 copies of that episode? The XML is for metadata item 606360, which is a 1080p version. Your log shows it playing 608912, which is a 4K version.
According to your logs, the video is being remuxed and the audio is being transcoded (your TV doesn’t support EAC3). Your PMS is not having any issues keeping up. The error reported is that the client did not receive the file fast enough
11-30 17:23:12.585 i: [video] Buffering due to network too slow
11-30 17:23:14.597 i: [video] Buffering has now occurred for over 2 seconds, warning user.
It’s not easy to diagnose this error. It could be a network issue, PMS too busy doing something else to send the file, your drive is busy so PMS couldn’t send the file, or some other bottleneck.
Do you have any 1080p content with really high bitrates you can try to see if they show the same issue? The one you were playing has an average bitrate >50 Mbps. It was over 60 when it ran into the issue.
There were also warning in the log that your drive was running low on space. Maybe your PMS triggered something on your OS related to low disk space. Try freeing up more space and see if this video still has the problem.
Took me forever to see the update…sorry.
I must have grabbed the wrong XML, you’re correct that I have both a 4K and 1080p copy of that show.
Let me see whether I have any high bitrate 1080p content (or if I can just make some for a test).
Disk/Network performance shouldn’t be an issue. And I assume the “low space” warning was because I run my Plex temp folder on a 50GB ram disk.
Here is the correct XML for that media (attached)
It looks like the highest 1080p bitrate I have is 38Mbps…I will test that but will also create some test material that shoots for over 60Mbps for testing.

It’s some sort of transmission issue, but there’s not enough info to know.
And I assume the “low space” warning was because I run my Plex temp folder on a 50GB ram disk.
PMS sees 5 GB. PMS has not been tested to use a ram disk so I don’t know if this might have an impact. Can you try moving the transcoder folder to a regular drive and test?

This now matches what is playing. Still don’t know where the problem is.
In you rinitial post you said:

But this is a 4K show, so I’m confused.
