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.
