DLNA - missing subtitle track

Server Version#: 1.32.8.7639
Player Version#: -

Hello, I have problems with DLNA server from Plex and subtitles. I have video file named “video1.mp4” and next to it I have “video1.en.srt” and “video1.srt”. I want to play video in VLC (tried Android app & PC) and I want to see subtitles there. Ideally as an option under “subtitles” menu. However currently there is no Subtitle track available and I have no idea why.

I did check logs from Plex server and I can see following message there:
Aug 20, 2024 12:33:24.242 [2936603504] Ladění — [Req#3322] Subtitles: Found a candidate subtitle language [xx] for a foreign film
Aug 20, 2024 12:33:24.243 [2936603504] Ladění — [Req#3322] Audio Stream: 2819, Subtitle Stream: 2859

So it seems to me, according to guides, that server correctly detected and found standard .srt file and it should include it into the played video. But for some reason that is not happening.
Subtitles are correctly added when video is played in Plex from browser or Plex app. But I really need to use VLC.

Any ideas what can I configure or how to make it work?

DLNA mostly only supports Direct Play.
But Direct Play means the video file is sent to the client without any modification. Which means the subtitles cannot be integrated.

You will either need to

  • integrate the subtitle yourself, (use MKVtoolnixGUI to easily do so)
  • stop using DLNA and use a proper Plex client

Hmm, I was using Twonky as DLNA server in the past and it works with that without any issues and out of the box…
Its a pitty Plex cannot do similar stuff since its much advanced.

Problem with integrating subtitles by myself is, that it takes extra time (I need to turn on PC and somehow use the program to do the integration). It´d be much better if the integration would be done by Plex itself since it can detect subtitle files and its also capable of transcoding…
