Jellyfin cannot load CUDA

[Big0]

Hello i recently installed jellyfin and configured hardware acceleration with a nvidia gtx950 everything works fine except when trying to run 4k movies i tried to run a 4k movie once it worked then tried it again and it stopped working i tried on different 4k movies but doesn’t work. I already asked on truenas forum but they found nothing really so im asking here i already checked compatibility with my gpu and cuda is installed i also checked that my nvidia pod didn't crash but it worked perfectly so if someone can help i would appreciate it. 
here is the jellyfin log:
