Hey, so im using plex on android TV and been having issues with subtitles and transcoding. My Server is ran on a Terramaster NAS so CPU isnt the most powerful. I’ve been tinkering with file formats in case that is the issue, that being switching from HVEC to H264 exclusively.
I will add, AAS subtitles did work for a time then suddenly caused issues. I’ve done the usual changes on the player such as “only burn advanced format subs”. Now I did come across an interesting thing, playing the video without subtitles first caused this :

This is to be expected, when then turning subtitles back on, it played without transcode and the subtitles worked!
Then I tried replaying the video, with subs on by default and get the following:

Turning the subs off with the video playing, which was transcoding has this output:

Then reenabling the subs with the video playing still:

So to me, it seems just turning subs “off and on again” seems to correct transcoding of subs.
I have tested this with another file format, that being HVEC Main 10:

This caused the usual transcode issues, When disabling subs I get Direct play with no transcode:

After reenabling subtitles, the stream was uneffected and remained on Direct play:

Just to make sure this wasn’t a delay in transcode kicking in, I allowed the video to play in full with subs on and there was no further issues. A remote stream also started while testing the full episode playing and no further issues were seen:
