Samsung Q95 - forced CC subtitles

[RandomFinnishDude]

Server Version#: 1.24.4.5081-6000
Player Version#: 5.25.3 / 5.5
For the last few weeks some of my shows are showing forced closed captions. For the Family Guy in the picture Plex on Windows shows only SRT text available and that is enabled. But for some reason my TV shows also closed captions that are usually in the middle of screen. And mostly they are incomprehensible, on the example they are correct.

So it does not show them in other apps like the web app? Are they in the file?

[RandomFinnishDude]

Those CC subs that have black background are not visible on web nor on android. I can’t turn them off from my tv. I tried the same file on VLC and I can see two tracks of CC subs.

Is there and option to disable closed captioning on the Samsung TV app?

[RandomFinnishDude]

So no input to this problem?

Closed captioning is forced when it is present in the file but it can’t be turned off?

I guess it’s a feature not a problem then…

If CC is enabled on the TV, it’ll get enabled when the video is playing regardless of if you selected it or not from the Plex app. This is not something we can control on the app, unfortunately so you’ll need to manually disable CC in your TV’s settings.

[RandomFinnishDude]

Tried that, settings are off on tv but still visible on Plex.

Looks like EIA-608 (aka Line 21) subtitles. They are part of the video stream, not a separate track.

Examine the file with MediaInfo. If EIA-608, you’ll see something similar to:

Text #1
ID                                       : 4113 (0x1011)-CC1
Menu ID                                  : 1 (0x1)
Format                                   : EIA-608
Muxing mode                              : SCTE 128 / DTVCC Transport

You could check if this is EIA-608 subtitles. MKVToolNix apparently doesn’t see those correct and in consequence won’t offer you an option to drop them. You can however drop them using ffmpeg (native version or the one bundled within your PMS): ./Plex\ Transcoder -i "<INPUT_FILE>" -codec copy -bsf:v "filter_units=remove_types=6" "<OUTPUT_FILE>" Where <INPUT_FILE> and <OUTPUT_FILE> are the full paths of the respective source/output files.

Media info shows

Text
ID/String                        : 3
Format/String                    : UTF-8
CodecID                          : S_TEXT/UTF8
CodecID/Info                     : UTF-8 Plain Text
Title                            : English
Language/String                  : English
Default/String                   : No
Forced/String                    : No

VLC shows 1 SRT + 2 CC tracks.

When opened in Handbrake there are English UTF-8 and English Closed Caption CC608

Try removing them with the Plex transcoder (see previously linked thread) or ffmpeg.

ffmpeg.exe -i “inputfile” -codec copy -bsf:v “filter_units=remove_types=6” “outputfile”

[RandomFinnishDude]

Yeah, I don’t know how to use the transcoder. And it is not that big a deal if it takes so much effort. Thanks anyway.

I also have this issue with my samsung Q95 tv (2018 model).

I do not have CC enabled afaik, it’s not even an option I can enable atm.

So I have this issue to, a 2-year old samsung “smart”-tv with Tizen. The FFMpeg.exe command above from @FordGuy61 works but it’s quite tedious to do on all affected media. Maybe someone from Plex might forward a Feature Request so the PMS might do it for us? Just a tick-box somewhere to detect this (if it is possible to just detect, should be as it is possible to remove) and remove it before adding the media to library?
