Feature Request: Subtitle Support

[jibon57]

Hello,

Thanks for the plugin. Can I use subtitle?

Thanks

You can, it hasn't been abstracted into the plugin to be easily used though. So you'd need to make the native calls with the video player ios and android instances at this time. I'll change this to a Feature Request issue. Thanks 👍

Android method: https://developer.android.com/reference/android/media/MediaPlayer.html#addTimedTextSource(java.lang.String, java.lang.String) I'm not sure about the iOS method (not my specialty).

Hi, any chance to get this feature?

I would advise submitting a PR. For me, its not a core requirement so I don't think this will happen any time soon.

Thanks for reply. Will you please give me little bit more hints? I am coming from web development knowledge. Don't have good knowledge on Android or IOS core. I can try by myself if you give me a good start :)

If you want the simplest way to start with this would be to add a public method on the VideoPlayer class.
Lets look at this line https://github.com/bradmartin/nativescript-videoplayer/blob/master/videoplayer.android.ts#L403 for the public isPlaying method on the android source.

So you could add a public method called setSubtitleTrack() or something like that after the isPlaying method since that is inside the VideoPlayer class. If you look at the isPlaying class it's calling this.mediaPlayer.isPlaying(). Where this.mediaPlayer (you can go up to the creation of the view instance and see it is equal to a new MediaPlayer https://github.com/bradmartin/nativescript-videoplayer/blob/master/videoplayer.android.ts#L325) is calling isPlaying(). At this point we are calling the native isPlaying method from the android MediaPlayer - documented here. So inside your public method to set the subtitle you can call this.mediaPlayer.addTimedTextSource(....) in the android docs here https://developer.android.com/reference/android/media/MediaPlayer.html#addTimedTextSource. That overload of the native method is expecting the android context, a url, and a mimetype as string - there are 3 other overloads for that method, which you can find in the Android docs right above the previous link.

@bradmartin, Thanks for the hints. I found one project related with subtitle for android here: https://github.com/Sriharia/Subtitle-Converter
I am also checking it, if I can understand :)
