I am using an HDHomerun tuner. It records the shows as .ts files. When I play those files back in VLC I can use the subtitles. Plex doesn’t even give the option to turn them on.
Is there a setting I need to change?
These are not subtitles but Closed Captions if you are in the US.
Closed Captions is something Plex is working to roll out to more client platforms.

Maybe you can help me understand something. I often hear this distinction being made between closed captions and subtitles. The closed caption data, as I understand it, is stored not as a separate stream but as frame data. Does it then follow that something like this (Can ffmpeg extract closed caption data - Stack Overflow) can be done in post-processing to extract sidecar subtitles for clients that don’t support closed captioning for DVR playback yet?
In the US for example Closed Captioning is NOT a separate stream but is intertwined with the video itself. When you think back to ANALOG TV and understand how things worked in the analog world before digital it makes sense.
But in any case it’s just different than subtitles which are complete different stream just like the video and audio and there can be multiple subtitle streams in a file.
To complicate things more on closed captions they are handled differently at times in NTSC vs the PAL world as well.
If you want a complicated answer let me know and I’ll put something together for you.

Thanks for your response. I’ll run a few tests to determine whether I can extract the closed caption data as subtitles during post-processing.
Your answer is consistent with my understanding of the matter, and although I’m always interested in the most complicated answer available to me, I think the assurance that CC support is being worked on for the remaining clients is sufficient for me at this point.
When I get the opportunity to play around with it, I’ll post what’s required to extract an .srt from the embedded CC and remap it for clients that don’t support sidecar subtitles.

Try that. That’s about the best you can do right now and it works really well. It will extract a CC if possible and convert it to a subtitle that plex can use in all it’s clients.

Thanks, @cayars.
I will look into that. FFmpeg leaves something to be desired in regard to CC tag processing, so I suppose there’s no sense re-inventing the wheel if CCExtractor can already do this with the --notypesetting flag.
