Graphic Style Subtitles

Hello, Last year I posted this question on the emby forums. https://emby.media/community/index.php?/topic/79020-spu-subtitle-support/&tab=comments#comment-804093
Thought I would ask here.

Hello, I have a few Star Trek movies, and episodes that have a text commentary option that I’ve included when I ripped them to mkv files.

The problem is emby doesn’t seem to support the subtitle, nor does vlc (at least not on my two linux boxes) Although when I use the default Gnome video player it shows fine.

As you see through the thread, based on the properties of vlc Properties of the codec in VLC show it’s a DVD Subtitle (SPU) and Emby just shows it as DVDSub.

A year later I was setting up a new fedora machine, and discovered that the subtitles where working fine, again with the gnome player, but I didn’t have the ffmpeg codecs installed, I was using the gstreamer plugins.

I’m wondering if it’s possible to have jellyfin support the gstreamer plugins along with the ffmpeg codecs, or am I just asking for too much? lol

Thanks
