LG Oled buffers/stutters when watching 4k videos

[RyanIV]

Hello,

I recently installed Jellyfin on my computer and connected it to my LG OLED 4k tv and was able to stream some lower quality shows/movies without much difficulty (I am using direct play with no hardware acceleration). However, I am now trying to watch 4k movies on my tv and it seems to be having a hard time with it. When I have the bit rate at 4k 120mbps, it buffers the most. However, it still buffers even when I have it at 1080p as well. The movie will play for a few seconds, then it will buffer and be frozen for 5~10 secs and then it will resume playing for a few seconds only to keep repeating the process.

Here is the relevant information regarding my setup:
Jellyfin version: 10.8.10
Installation method: Windows installer (Windows 10 64bit)
Computer CPU: AMD Ryzen 7 3800X 8-Core Processor 
Computer GPU: AMD Radeon RX 5700 XT
Client: LG OLED 4k TV (Model number: OLED65C1PUB)

I have gone ahead and attached the ffmpeg transcode log below.
I have also attached the regular deubg log file as well.


If any other information would be helpful please let me know! 
Thank you!

Not sure on your specific model (check the specs) but I know the C1 was notorious for having a really garbage network card. The hard-wired port on mine is limited to 100 Mbps. If I were to guess, it's not a Jellyfin issue.

Thanks for the tip!

I just did a quick speed test on my tv and I got a speed of 23.8Mbps...
I will try using a USB to Ethernet adapter and see if it that increases the speed and removes the buffering issue. I'll add a follow up comment on this thread in a couple days when the adapter comes in.

Give Wi-Fi a shot. I had better luck with speed there. I ended up caving and using a Roku Ultra for my remux needs.
