When using libVLC for Android how do I know if subtitles (text track) are external (.srt, ass) or part of video container file (text track inside .mkv)?

https://code.videolan.org/videolan/libv ... id-samples

https://code.videolan.org/videolan/vlc-android

Code: Select all

// MediaPlayer.getSpuTracks() - Get the list of available spu (subtitle) tracks.

Code: Select all

MediaPlayer.TrackDescription[] trackDescriptions = mMediaPlayer.getSpuTracks();

Code: Select all

for (int i = 1; i < trackDescriptions.length; i++) {

Code: Select all

MediaPlayer.TrackDescription description = trackDescriptions[i];

Code: Select all

Log.i(TAG, "loadSpuTrack " + description.name + ", id " + description.id);

Code: Select all

}

Output

loadSpuTrack Track 1, id 2
loadSpuTrack Track 2, id 3
loadSpuTrack Track 3, id 4
loadSpuTrack Track 4, id 5
loadSpuTrack Track 5, id 6

It just searches and adds all external text track files (.srt, .ass) from parent file (directory) of video file (.mkv) and from video file itself

But there is no API (Java methods inside MediaPlayer or LibVLC classes) to identify if added subtitles are external or internal (from video file container), no method to disable adding external subtitles

Is there any solution?
