kakmoster Posted May 23, 2018 Share Posted May 23, 2018 Hey, my Plex container is not using full CPU when transcoding or optimizing. I can only transcode ~25Mbps HEVC to 10Mbps x264. More than that requires a lot of buffering. It uses ~15-35% of the CPU. Same while using HW and SW transcoding. I have a i5 8600T processor, it has ~11100 passmarks. A Ryzen 1700X with ~14600 passmarks can transcode 85Mbps HEVC (SW) without a problem. However the Ryzen does not run Plex in a docker, it runs Plex in a VM on Proxmox. Quote Link to comment

Cadvisor, couchpotato, r(u)torrent, Plex, qbittorrent, sonarr and taitulli. Edited May 24, 2018 by kakmoster Quote Link to comment

Have you excluded unRaid (and therefore docker) from executing on certain cores? It seems that when Plex is transcoding a video with .pgs subtitles it only uses 1-2 cores or something like that. I tried transcoding a movie with .srt subtitles and now I can transcode a 86Mbps 4k HEVC to 12Mbps 1080p x264 file without any problem! EDIT: 122,7 Mbps 4k HEVC to 12Mbps 1080p x264 works great with 95-98% cpu utilization! 916Mbps file was out of the question! Edited May 24, 2018 by kakmoster Quote Link to comment
