Video playback

[AKayNC]

Dear community,

Greetings! I'm new to Jellyfin and have begun adding my media content. I've encountered an issue when playing a 1080p rip on my 4K monitor through the Jellyfin Media Player. There's a noticeable stutter or lag, similarly to framerate dropping. However, it plays flawlessly through VLC or WMP on either monitor. The same rip plays perfectly on my 1080p second monitor through Jellyfin.

I suspect that VLC and WMP are compensating or upscaling the 1080p content when playing on the 4K monitor. Is there a setting or configuration within Jellyfin that would enable similar behavior and resolve the playback issue?

My system configuration is:
* Windows 11 Pro 24H2
* Intel i5 12600k
* Gigabyte M32UC Monitor
* All software are up to date (server/media player)

Thank you for any assistance provided.

Does this only happen with a particular video or for all videos?

All the movies I ripped using MakeMKV, retaining the main movie, highest audio, english subtitles, and chapter markings without compression (no handbrake). However, I'm starting to consider if the rips themselves might be the issue. While troubleshooting some more, I noticed that a 1080p rip from a friend plays perfectly in Jellyfin on the main 4K monitor.

Let's try remuxing one of these files.

Open a command prompt and run this command. Change the input path to one of your problem videos.

Code:

cd C:\Program Files\Jellyfin
ffmpeg.exe -fflags +genpts+igndts -i "C:\path\to\problem\video.mkv" -map 0 -codec copy -max_muxing_queue_size 2048 -max_interleave_delta 0 -avoid_negative_ts disabled newFile.mkv
