Subtitles

Subtitle selection can be performed with the SDK via the player controller native interface. Currently, the SDK subclass AVPlayer allows only for the activation and deactivation of subtitles.

Prerequisites

A clear stream with subtitles is available for testing.

Example code

The following code sample shows how to select subtitles.

CODE

- (void)onTrackChanged
{
  NSArray* subtitlesArray = [_playerController getTrackInfo];
  if (subtitlesArray) {
 
    [subtitlesArray enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
      NMPTrackInfo* trackInfo = subtitlesArray[idx];
      NMPCLog(@"Subtitle track %d: type is %d, language is %@", idx, trackInfo.type, trackInfo.language);
    
      // Current SDK only returns one track.
      NSUserDefaults* userDefaults = [NSUserDefaults standardUserDefaults];
      bool subtitleEnabled = [userDefaults boolForKey:@"subtitleSwitch"];
      if (subtitleEnabled) {
        [_playerController selectTrack:0];
      }
    }];
  }
}
