Preselect audio/subtitle track

[RichardDorian]

Hello,

I've been using Just Player as my main video player on my phone and TV. I'm currently working on an Android application for Jellyfin. I'm being curious about if it is possible to preselect the audio or subtitle track when opening a video stream.

If it is not currently possible here's my idea: put a preferred audio/subtitle track in the android intent and then just player selects the specified track according to what's in the intent. On the other side it looks like this:

Uri videoUri = Uri.parse("...");
Intent intent = new Intent(Intent.ACTION_VIEW, videoUri);
intent.setDataAndType(videoUri, "video/*");
intent.putExtra("PREFERRED_AUDIO_TRACK", "2");

startActivity(intent);
