Remarks

Class encapsulating subtitle data, as received through the MediaPlayer.OnSubtitleDataListener interface. The subtitle data includes: <ul> <li> the track index</li> <li> the start time (in microseconds) of the data</li> <li> the duration (in microseconds) of the data</li> <li> the actual data.</li> </ul> The data is stored in a byte-array, and is encoded in one of the supported in-band subtitle formats. The subtitle encoding is determined by the MIME type of the MediaPlayer.TrackInfo of the subtitle track, one of MediaFormat#MIMETYPE_TEXT_CEA_608, MediaFormat#MIMETYPE_TEXT_CEA_708, MediaFormat#MIMETYPE_TEXT_VTT.

Here is an example of iterating over the tracks of a MediaPlayer, and checking which encoding is used for the subtitle tracks:

MediaPlayer mp = new MediaPlayer();
            mp.setDataSource(myContentLocation);
            mp.prepare(); // synchronous prepare, ready to use when method returns
            final TrackInfo[] trackInfos = mp.getTrackInfo();
            for (TrackInfo info : trackInfo) {
                if (info.getTrackType() == TrackInfo.MEDIA_TRACK_TYPE_SUBTITLE) {
                    final String mime = info.getFormat().getString(MediaFormat.KEY_MIME);
                    if (MediaFormat.MIMETYPE_TEXT_CEA_608.equals(mime) {
                        // subtitle encoding is CEA 608
                    } else if (MediaFormat.MIMETYPE_TEXT_CEA_708.equals(mime) {
                        // subtitle encoding is CEA 708
                    } else if (MediaFormat.MIMETYPE_TEXT_VTT.equals(mime) {
                        // subtitle encoding is WebVTT
                    }
                }
            }

See MediaPlayer#setOnSubtitleDataListener(android.media.MediaPlayer.OnSubtitleDataListener, android.os.Handler) to receive subtitle data from a MediaPlayer object.
