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!!!
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.
