Hi,
I’m experiencing constant buffering / stuttering on Plex for Android TV. The playback device I’m using is the Shield TV Pro (2019), running the latest version of the Plex app from the Google Play Store. The server, which is hosted remotely, has more than enough upload bandwidth for me to stream from. My download speed is about 100Mbps and I’m connected via WiFi (5GHz). Everything is direct-played, verified through Tautulli. The file in question is 1080p and according to Tautulli, has a quality of 19.3Mbps, and a bandwidth of 34.7Mbps. When I play the file, it seems the video is not buffering ahead, leading to playback issues. Other higher bitrate files tends to suffer the same fate, while lower bitrate files tends to stream just fine. I stick to 1080p or below, so no 4k.
There is no buffering/stuttering when I play the same file through the Plex for Windows Desktop app, or the Plex for Android (Mobile) app. On the Desktop app, I can even see that the video has buffered ahead on the progress bar.
My friend who streams from the same server, and has the same internet speed, also struggle to play the file in question on his Fire TV Stick 4k Max. He is using the official Plex app from the Amazon Appstore. He also has a buffer-free stream when playing on the Desktop app.
So it seems my Plex client on the Shield is not buffering ahead fast enough? Is this a network issue? My internet connection should be able to stream such a file without issues, since it works perfectly on the desktop and mobile app. I’ve also tried the Plex for Kodi add-on by pannal with no success.
Any pointers to diagnose this problem would be much appreciated!

While transport speeds are important, actual measured throughput is most important.
This is because you’ll be able to see what you can really use of the provisioned bandwidth.
A good tool for this is iperf3
How to use it:
Install iperf3 on the remote PMS server (native app, temporary CLI version, or docker container)
Install the iperf3 client side on the device to be tested – and/or – your LAN so you can measure what you actually get from the remote.
Start the remote iperf3 in “server” mode iperf3 -s.
On a client machine on your lan –iperf3 -c ip.addr.of.server (Up)iperf3 -c ip.addr.of.server -R (Down)
It will push the network as hard as it can. It’s common to see “retry” messages.
Here’s my LAN

It looks like the measured throughput is quite low from the results, but is it low enough to continuously buffer the file mentioned above?
Here are the results when I run iperf3 on my Windows 10 laptop:

The tests i performed on the two different devices seem similar, but only one of the devices have buffer-free playback.

It looks like you forgot to run the -R (Reverse) test where the remote host is sending.
It will tell you the remote server is sending. This is the important test because it shows how fast you can receive.

When it comes to “buffering” , there are two meanings / parts.
Part 1 - Initial local client playback buffer loading BEFORE playback starts
Part 2 - Backfill as the video plays and the client asks the server for more data so it doesn’t run out and stutter/pause.
What you show me above is clear that you don’t have much throughput.
First test shows an overwhelming median value of 21 Mbps. (Peaks don’t count)
Second test shows a range from 7 → 9 Mbps with mean of 6.67 Mbps
That Windows result looks abysmal – dropping every other second’s worth.
You need to use a more reliable remote server to test with.
I’ll send you a PM with a good one.

I’ll try now with the more reliable server.
I am getting the same error - I get constant buffering on my clients when I’m outside my home. When I ran the i ran the iperf -R, I got good results -
Blockquote
Today, I saw a case where one user had AV1 codec encoded video playing to his shield.
The Shield Pro does not support HW decode of AV1 so PMS had to transcode it.
The result was buffering.
I’m going to need Plex DEBUG server logs which capture the start of playback for some of these videos which buffer to see what’s happening.
Hi,
Plex Media Server Logs_2024-02-03_15-58-45.zip (3.1 MB)
Buffering (SOFTWARE TRANSCODE) on a Synology NAS, when trying to play AV1 codec is EXPECTED.
The Shield Pro 2019 does not support it in hardware
None of the Synology GPUs have AV1 hardware capability.

None of the Synology CPUs are fast enough to perform AV1 decoding in real-time
Thanks. That is what I suspected.
