Jellyfin constantly buffering despite having a direct connection

[Robert Urrutia]

Is there a way to know what's the problem with my setup? I dont think I should be having constant buffering with my Jellyfin server. My NAS its just a simple Windows 10 PC with a RAID5 Pool, I exposed the 8096 port on my router and my internet bandwidth is about 400Mbps and 150Mbps where I want to stream movies (gf's home). Apparently there is no difference if I enable QSV from Intel to decode or disable all hardware acceleration so I dont know what to check, please some help:)

See if I'm understanding correctly, you have a 400Mbps upload, she has a 150Mbps download? 

When watching the movie at her place, under playback info, does it say that the video is being transcoded or direct playing? Can also check from the logs; and actually does the log (admin dashboard>advanced>logs) show any errors?

 

Also for context, are the files substantially large? How are you connecting at her place, through a computer/phone/tv/console :: browser or app?

Are all video playbacks affected, such as small low bitrate, low resolution files?

Yep, my place has 400Mbps both upload and download, she has 150Mbps both upload and download. Which I think is enough? The files are around 2GB~ at  much, 1080p encoded with HEVC and 5.1 Dolby Digital Plus audio. Nothing special of an encode I guess but good enough. Playback info shows Auto - Direct Playing. I have tried with PC, laptop, phone and browser and still buffers, and buffers constantly like every 3-5 seconds. Havent take a look at the logs, I will.

Yes plenty of bandwidth, and that file size is very reasonable (making sure it's not 50-60GB).

If the playback is direct, then no transcoding is occurring and QSV isn't being utilized so mostly likely no issues there. 

 

I'm interested to see what the logs say

Took a look at the logs, basicaly empty except for yesterday's log where I was moving around transcoding and configurations trying to figure out whats my problem.

Mind taking a look?

log_20231210.log

Based on that log, looks like transcoding was occurring, were you forcing it to transcode?

 

What CPU is in the server?

[BM813]

the error of concern is 'containerbitrateexceedslimit' ; hence a forced transcode, possibly a software bug as mentioned here

 

Other things to try:

 

From Dashboard>Playback>Transcoding

-Select transcoding thread count as Max (seeing a thread count of two in the log)

 

From Client Player

Profile>Playback>Video Quality 

-Select the maximum bitrate (4k-120Mbps) home & Internet (not sure how you are connecting remotely) some devices report an

 

Is there a GPU in the machine, model? If so, could maybe use it for transcoding needs depending on NVENC generation

Yeah I was kinda playing trying to figure it out why it wasnt working. The CPU is Intel Core i5-10400. Here is a cleaner log with only direct playing (Auto)

Thanks for your reply, I added a cleaner log in the previous reply. I guess it could be something related to these lines 

"[WRN] [45] Jellyfin.Server.Middleware.ResponseTimeMiddleware: Slow HTTP Response from". 

I changed the settings you said, still no improvement. There is no GPU in the machine, still I enabled QSV just in case. But enabling or disabling Transcoding has no effect either

As I understand that line is a hold over from previous versions of Jellyfin, It occurs on my config on LAN with a 10gb fiber connection, a status code of 200-299 is successful. 

 

CPU is very adequate, even for software based transcoding.

 

At this point I don't believe it's an issue with your Jellyfin setup, so without knowing more:

- hardware being over taxed by something else running

- your DDNS config

- Network congestion / Network hardware being taxed by a lot of devices

- it's running on windows (this shouldn't really be an issue, but it's windows)

 

Sorry I can't be more help, I take it Jellyfin serves up that stream just fine over LAN?
