Hello fellow selfhosters! I reformatted my USB hard drive from exFAT to XFS because I needed a filesystem that could handle hardlinks. I remounted the hard drive and now jellyfin webUI has a severe stuttering problem on some videos, all of them are MKV but it may be a coincidence. On android (using exoplayer) the same files works smoothly. what could be the problem?
in the logs I get a bunch of Slow HTTP Response from http://fedoraserver:8096/ to 192.168.1.30 in 0:00:07.4635856 with Status Code 200
OT: while looking at the logs this happened
SOLUTION: I enabled hardware acceleration, and manually selected also the HEVC
and Allow encoding in HEVC format
settings, and now the stutter disappeared! thanks to everyone for your help!!!
It could be an issue with the codecs (browsers are usually pretty limited in what they support). You could try to use a client like Jellyfin Media Player instead. It bundles libmpv, so it plays almost any video format there is.
I had a similar problem. For me it was because some of the videos were encoded with x265 which some client devices could not decode properly. Therefore the server had to decode them but it was not fast enough to do it.
I guess that is why on the Android device the videos are smooth, it can handle the decoding.
How did you solve it?
not OC, but i ended up redownloading whatever was x265 and replacing it with 264 or anything else.
also the 1060 in my NAS can do NVENC encoding. that helped a lot with compatibility.
You can also use something like handbrake to convert everything to 264 instead of redownloading everything. You can also set it up to convert after items are downloaded.
Does jellyfish not transcode on the fly?
Yes, but if the server isn’t fast enough to do it, then you’re going to have a bad time.
It can but it’s the server hardware that decides your performance, you can just avoid transcoder on the fly and have h264 mp4 and can run JF on a toaster smoothly.
i had this problem. i fixed it with a faster machine. same os, same files. more cpu worked.
You mean a new sever or a new client?
yes!
server. it was choking on decoding
But I know of people running jellyfin on a raspberry, I have an old laptop but it’s not that old… There’srno way to run it smoothly?
yeah, re-encode to a lighter encoding like 264. might be slightly larger, but less work for the cpu
This may help: Container compatibility. MKV files will be remuxed when played via WebUI. Try playing an MP4 file and see if it’s the same.
Well this info kills any desire I have to install Jellyfin. =(
That has nothing to do with Jellyfin itself. Any comparable service will have the exact same issue because the root cause are browsers not supporting the container.
