Is there support for image based subtitles? If not, can this be a feature request?
I'm using Plex to watch media on a 4660X Roku Ultra from late 2018, but turning on subtitles requires media to be transcoded because the subtitles are PGS (image based).
Note: I also have an Amazon Firestick 4K from around the same time and it does not have this limitation. I can select either subtitle track from any video and they display properly without transcoding media on my Plex server.
I prefer the Roku 100% over the Firestick, so I am really hopeful something can be done with the Roku to begin allowing image based subtitles without the need to transcode them into the video.
