I recently installed 1.24.0.4897-411e7667f and upon trying to play something on my Roku I noticed subtitles were burned in.
I then tried different files, h.264, h.265, MPEG2, everything transcodes with burned in subtitles and there’s no way to stop it.
I tried the Windows app and the issue does not occur, haven’t tried anything else.
I rolled back to the latest public version and everything works fine, so I’m assuming this is server related.
First thing to do is during playback on Roku bring up the on screen controller and select playback settings on the far right. ( the three dots) On the Playback settings screen select Playback Info then make the top Playback: Trancode option focused. While it is focus on the bottom it should say why it is transcoding.
