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!!!
