media_player_add_slave does not show SRT subtitle

[GreaterDane]

Hi,
I can only get libVLC to play my SRT subtitles when the filename exactly matches the video filename, even when I explicitly load the subtitle file like so:

Code: Select all

// libvlcpp binding calls libvlc_media_player_add_slave() m_Player->addSlave(VLC::MediaSlave::Type::Subtitle, subtitleFile, true); ... m_Player->play();

The addSlave return code is OK, so I'm not sure why loading the SRT in this manner does not work. Please advise!

Our plan is to have multiple possible subtitle files per video. Given this, I'm working around the issue by copying the currently-selected subtitle file to "VideoFileName.srt" before playing in libVLC.

This is very inelegant, though, and I'd prefer a better solution.

In case it helps...
I've seen multiple subtitle files, for different languages, titled like this:
nameofmovie.mp4
nameofmovie.en.srt
nameofmovie.fr.srt
nameofmovie.es.srt
VLC then shows the language (English, French, Spanish) as the name of each subtitle.

hi,

following code should work (in python for my tests, but that the same for C++), beware that vlc_media_slaves_add expect and uri and not a raw path.

Code: Select all

import vlc i = vlc.Instance() m = i.media_new_path("/home/pierre/Videos/foo.mkv") m.slaves_add(vlc.MediaSlaveType.subtitle, 1, "file:///home/pierre/Videos/plop.srt") mp = i.media_player_new() mp.set_media(m) mp.play()

Thanks chubinou! I was indeed passing a file path rather than a URI. I'm curious, why was I seeing a successful return? Does vlc_media_slaves_add not attempt to load the URI?

Wish I could edit the topic title, now that I've been shown the error was mine.

the media is opened when you play it.
