Server Version#: 1.18.2.2041
Player Version#: 6.5.2 Apple TV 4K
I’m having issues direct playing Angel Has Fallen UHD 4K HDR. It keeps stuttering/stopping to buffer after 10-15 seconds during playback. I am using a Synology DS 1511+ with link aggregation (2Gbps) as the server. The client is an AppleTV 4K. The server Synology CPU usage is 45% during playback. Within the Plex dashboard, it shows the local connection only reaching 75Mbps.
what is the actual bitrate of the file?
(Hover over it, Ellipsis -> Get Info -> View XML)
Copy & paste the media portion only (down to the </media> marker)
using
``` (back ticks)
paste XML here
```
It will appear as

and won’t be interpreted by the forum.
It might be possible the CPU isn’t capable of creating the manifest blocks fast enough anymore. The D525 is a very old 32 bit CPU.
If you look at the NAS compatibility guide, you’ll find it’s marked with a “Caution” flag due to the lack of performance.
It plays fine when I connect the Infuse app to Plex.
Here’s the XML file as well as a video of the debug screen for the enhanced player. It keeps freezing as the buffer drops to 0 seconds.
When using infuse, which I also have, your NAS is being only a NAS. it’s providing the raw data. Infuse is doing all the repacking and then rendering by itself on the glass.
With Plex, it must read the data and repackage it into chunks of ‘manifests’ to send over TCP. It’s subtile, but when on the edge, it makes a difference. Synology isn’t known for, and never has been, a CPU capable of ‘crunching’. It’s a good NAS but that is the focus.
It is probably time to retire it as your PMS server and put PMS on a newer processor.
Thanks for the help, l’ll probably stick with Infuse for 4K for the time being since I don’t want to run another machine or pay for a new NAS device right now.
Are there any plans to improve upon the Plex player to offload some of the processing to the client, or at least make that an option?
Some things have already been offloaded.
The problem is HDR.
The app isn’t written in Metal and therefore has limitations.
