Issue with 4K playback - rsks1 - 2024-12-11
Hi everyone,
I’m running a server on Windows 10 LTSC with the following specs:
CPU: i5 7400
GPU: GTX 1060
Storage: SSD and HDD
Jellyfin works great for 1080p content, but I’m running into an issue with high-bitrate 4K content. Every ~3 minutes, playback freezes for ~45 seconds. Interestingly, this doesn’t happen when I use Plex with the same 4K files.
I’ve tested this on two endpoint devices—my gaming PC and an Apple TV 4K using Swiftfin—and the issue is the same on both. It also happens regardless of whether hardware transcoding is enabled or disabled.
For context, everything is wired with gigabit Ethernet, so network speed shouldn’t be the problem.

Any ideas on what could be causing this?

I don't see anything in that ffmpeg log that would point to a culprit. Is it transcoding in Plex?

Plex is under the setting "Play at original quality", it works if I have it transcode to 1080p.

I honestly don't have enough information to go on. Most of the time, this is caused by network issues.
It has been a long time since I used Plex. I can't remember if Plex will still transcode, if needed, when it is set to "play at original quality".

Unfortunate. It's most likely a weird windows issue, I will switch back to linux eventually.
