Hello,
I have the last release, I tried with direct play and transcoding but none is working, I really don't understand why. I have no problem with my other supports.
I don't quite understand your last sentence. What other supports ?
That aside, I must chime in with the others in saying that ".srt" subtitles work fine for me.
Perhaps you should give explicit examples of the folder structure and filenames used for the movies that fail to show subtitles.
Here is an example from my own library:
\\RASRV2\RAs2_F\Media (RAs2_F)\Movies\Ivanhoe (1982)\folder.jpg
\\RASRV2\RAs2_F\Media (RAs2_F)\Movies\Ivanhoe (1982)\Ivanhoe (1982).avi
\\RASRV2\RAs2_F\Media (RAs2_F)\Movies\Ivanhoe (1982)\Ivanhoe (1982).en.srt
\\RASRV2\RAs2_F\Media (RAs2_F)\Movies\Ivanhoe (1982)\Ivanhoe (1982).sv.srt
NB: The pathnames may look odd to you, as this is how my PMS computer sees the file shares from the server holding this movie.
Here the folder "Movies" from that drive "F:" of that server is one of the many source folders for my Plex section named "Movies", and in its subfolder named "Ivanhoe (1982)" I have that movie stored together with a poster file and two subtitle files, one English and one Swedish. Both of those subtitles work fine with Plex, using any of the Plex clients, including RasPlex.
It may also be useful to know exactly how you've tried to activate the subtitles for those movies.
RasPlex is based on PHT, which is originally a keyboard-based program, so it has keyboard shortcuts for lots of things.
'S' is the shortcut key to toggle subtitles on/off. 'L' is the shortcut key to switch language when you have multiple subtitles for a movie.
Such language switching also includes one switch step that disables subtitles.
In addition to using those shortcut keys during playback you can also select subtitles (if recognized by PMS) in the pre-play screen before starting playback, or in the OSD menu when pausing playback.
When having problems making things work in RasPlex it's often useful to verify if these things work correctly in some other Plex client, with the most widely available one being the Plex/Web client (aka: Media Manager of PMS) which runs in a normal Web browser. If your subtitles are not accessible through this media manager, then they will not be accessible to any other Plex client, as they are not recognized by the PMS server.
Sometimes adding correctly named subtitle files into a movie folder is not sufficient to make them recognized, and you may then have to open the pre-play screen for that movie in the Plex/Web media manager and give a command to reanalyze the movie. But often it's sufficient just to navigate into the pre-play screen for that movie, in order to make PMS aware of its subtitles.
