Android TV version 0.17

[Bond_009]

This may be a niche problem, and one that might be on the radar, or is just a configuration setting I have wrong. When attempting to use PGS Forced subtitles (Mainly for anime where it displays the signs and the song lyrics) do not work in the 0.17.x android tv client. I think it may trace back to the removal of LibVLC as a video playback engine, but is there a way to get them to work, or do I just not use them for now?

You need to enable transcoding so that they can be burned into the video.
They don't work with direct playing because the ATV player (Exoplayer) doesn't support PGS subs directly.

This not true, PGS subs are supported by exoplayer, see https://github.com/jellyfin/jellyfin-and.../pull/2690
