Trouble with EIA 608 captions in .ts file - Toyful - 2025-03-07
Hey all,
Hoping to resolve an issue I am having regarding subtitles in a MPEG-TS file.
The file is a tv broadcast that has some EIA 608 captions embedded within it. AFAIK, it should be supported according to this
When I play the file, I can't select the subtitles (i.e. pressing the CC button on my remote doesn't bring up the subtitle selection nor does the CC button show up when I pause the playback). AFAIK, the server does not do any transcoding when I play. Forcing it to transcode on the web client doesn't seem to affect the ability to use the embedded captions
The Jellyfin server I'm running is v10.10.6 and was installed from the official Apt repostories on the Jellyfin website. The server is running on the current Debian stable version. The client is Jellyfin for Android TV v0.18.3 running on a HiSmartTV A4.
Going to put the relevant ffprobe and mediainfo here:

RE: Trouble with EIA 608 captions in .ts file - TheDreadPirate - 2025-03-07
I'm wondering if this is a problem.
Code:
Stream #0:0: Video: wrapped_avframe
...
Muxing mode : SCTE 128 / DTVCC Transport
Muxing mode, more info : Muxed in Video #1Let's try remuxing the video for testing purposes.
Code:
ffmpeg -fflags +genpts+igndts -i "/path/to/video.ts" -map 0 -codec copy testFile.mkvI THINK that should separate all the streams instead of them all being wrapped together.
RE: Trouble with EIA 608 captions in .ts file - Toyful - 2025-03-07
Ah no such luck so far with the remuxing

RE: Trouble with EIA 608 captions in .ts file - TheDreadPirate - 2025-03-07
What the heck? No subtitles in the new file?
RE: Trouble with EIA 608 captions in .ts file - Toyful - 2025-03-07
Okay, so I've found that if I do the remux command from above, the subtitles are still there. I just have to add in the "-f lavfi" part in the ffprobe command like so:
Code:
~ ffprobe -f lavfi -i "movie='testFile.mkv'[out+subcc]"
