Roku Ultra: HEVC and DTS

xSeanxSean Posts: 217Members, Plex Pass Plex Pass

Does transcoding occur if a video is using the x265 codec or with DTS? I typically encode my files into x265 while keeping the audio at DTS or DTS-HD.

I've seen older topics on the subject where there have been some issues, but want to see how things are at this point in time.

    There has been some issues with DTS and DTS-HD (primarily audio-sync related). The x265 won't be an issue, though. I have taken to setting my Roku Ultras to just DD/DD+. My receivers will do DTS...but having it set to non-DTS will trigger the server to transcode DTS to AAC 5.1, which plays without issue. In this scenario, the HEVC is direct-streamed while the audio is transcoded...which requires very little of the CPU.
