Plex Server cannot handle transcoding with subtitles

I was having the same issue here

Diagnosing Transcoding Issues

I’m not sure it would help. There are two problems: Celeron CPU low performance, especially single-cores. Limited ASS support in the Plex Android / Android TV client. I transcoded a section of the video using Handbrake to HEVC 10-bit, Main10@L4.0@High and loaded onto my system (PMS on DS918+, Nvidia Shield Pro as client). With no subtitles, both the L6.2 and L4.0 videos direct play, without buffering, using the Shield as a client. Both have similar bitrates, 6.2 = 1741 kbps, 4.0 = 1732 kb…

Something definitely doesn’t add up that doing it via SW is faster than via HW on a J4125 Celeron.
