Plex won't Direct Play/Stream local 4k
Server spec: i7 4790k
Cast device: Chromecast Ultra
TV: LG 58UF8300
ISP: Verizon Fios 150 down
Hi, I am trying to Direct Play/Stream my local 4K HEVC Movie files, but they all are being transcoded and subsequently begin to stutter. Stuttering issues aside, what would cause my 4K movies to not play directly? I have tested multiple 4K movies and all seem to force transcoding. Could this be an issue with my TV? Plex? or something else entirely?
Also, any tips (server setting tweaks, etc) on how to mitigate the stuttering during my 4K transcodes? Increase the IPC buffer size? Could I optimize all the 4K videos?
