I’ve recently upgraded my Plex instance to separate out the storage side and the compute side. In general, I couldn’t be happier - the compute side is a little HP prodesk with a quicksync-capable CPU, and the results have been phenomenal.
I have one user who has been complaining about stuttering playback when doing Direct Play on a Roku 3 (2015). When they switch to transcoding, it works perfectly. The only time I’ve seen it, it has been doing a direct stream of MKV -> MPEGTS for the video container with a transcode of DCA 7.1 -> Stereo audio.
Bandwidth is not the issue and they were the only ones streaming at the time.
Do you think the Roku choking on it somehow? My 2017 Shield TV can fully direct play it without issue.
I was recently having issues with my Roku Premier stuttering on some media. It’s hardwired to the same network as the server.
What fixed it for me was changing the audio output in the main Roku settings to stereo. This Roku use to be setup with a receiver to decode the audio stream but is currently sending audio directly to the TV. I think decoding the audio was too much for the Roku.
