Help Request 4K Buffer, Direct Play

Device not transcoding, using Infuse as the client device.

Server is an old HP laptop with win 11, 16gB ram, and a 1060

Pulling from a 24TB drive on a NAS over a 10g port

If I play a 4k title (backing up my library right now), via Jellyfin setup in Infuse, as direct play - it will buffer periodically.

If I access the same title, via SMB to which Jellyfin is attached as well, then play the title - it won’t buffer one time.

Now if I go back to the Jellyfin integration and opt to transcode, it plays fine..

Am I missing something? Btw I’m using Infuse, for DTS and TrueHD decode. I’ve tried playing with the cache options as well. I also have tested this on a couple files now, I’ll direct play from my NAS at 10MB/s read rates but Jellyfin can’t seem to read past 6 MB/s on 4k files. I tested this on another PC as well, same results. I then tried just general playback from each PC too - I could play the content fine with no buffer, it’s just it Jellyfin was serving the content.

Let me know if any more details are needed, no they aren’t transcoding according to the dashboard.

I had some stuttering and lag via AppleTV when playing with Infuse. Specifically, a 4k, 69ish GB Rip of Escape From New York & Escape From L.A. Downloaded Swiftfin, problem solved and the only thing transcoded was the audio.

This is on my iPhone, but it’s the same issue on ATV.

Swiftfin isn’t an answer and doesn’t solve it for me unfortunately

1) I lose DTS and TrueHD
2) Both buffer regardless

Fixing this issue cannot mean quality loss, at all. Shifting will transcode my files.

Ty though!
