Hi, let me start off by saying that Emby its the best streaming server out there! Nice job and keep going!
I think it would be great to have an automatic feature that convert's .pgs subtitles inside .mkv files to .srt.
Let me give you an example of use case that's actually what I'm dealing right now:
I have a 55" LG 4K TV and i'm using the Emby app whis is beautiful btw.
I have several 4K HEVC BluRay movies in .mkv files in the server that have .pgs subtitles and different audio tracks for langs., the thing is that for me to be able to watch those movies I had to turn off all the transcoding options in my user profile.
If I turn on the transcoding options, it tries to burn the subtitles by transcoding the Video file.
I think that instead of transcoding the video file, it should be doing something like converting those .pgs existing subtitles to .srt files that are compatible with most DLNA devices.
I think it would be awsome if we could cron this to run on the less server busy hours so the .srt file is ready to play whenever is needed instead of doing it on the fly when maybe there's no enough CPU resources.
