Method Documentation

- (NSArray * OOAudioTrackSelectionProtocol) availableAudioTracks

Searchs for all of the audio tracks for the current asset.

It requires that a video has already loaded.

The following code snippet shows an example of this method. It assumes you are listening to the events of the OOOoyalaPlayer using notifications:

// assumes you are observing OOOoyalaPlayer notifications and you have a property
// like `@property OOOoyalaPlayer *player;`
if ([notification.name isEqualToString:OOOoyalaPlayerStateChangedNotification]) {
  NSNumber *state = notification.userInfo[@"newState"];
  if (state.intValue == OOOoyalaPlayerStateReady) {
    NSLog(@"available audio tracks: %@", [self.player availableAudioTracks]);
  }
}

Returns

NSArray of OOAudioTrackProtocol objects. It could be empty if no audio tracks were found.

- (id<OOAudioTrackProtocol> OOAudioTrackSelectionProtocol) defaultAudioTrack

Gets the default audio track from manifest.

Returns

An OOAudioTrackProtocol object or nil if nothing was found

- (id <OOAudioTrackProtocol> OOAudioTrackSelectionProtocol) selectedAudioTrack

Gets the currently selected (loaded) audio track.

It requires that a video has already loaded.

The following code snippet shows an example of this method. It assumes you are listening to the events of the OOOoyalaPlayer using notifications:

// assumes you are observing OOOoyalaPlayer notifications and you have a property
// like `@property OOOoyalaPlayer *player;`
if ([notification.name isEqualToString:OOOoyalaPlayerStateChangedNotification]) {
  NSNumber *state = notification.userInfo[@"newState"];
  if (state.intValue == OOOoyalaPlayerStateReady) {
    NSLog(@"selected audio track: %@", [self.player selectedAudioTrack].name);
  }
}

Returns

an OOAudioTrackProtocol object or nil if nothing was found.

- (void OOAudioTrackSelectionProtocol) setAudioTrack:

(id< OOAudioTrackProtocol >)

audioTrack

Requests the player to change the current audio track to the one provided as a parameter.

It requires that a video has already loaded.

The following code snippet shows an example of this method. It assumes you are listening to the events of the OOOoyalaPlayer using notifications:

// assumes you are observing OOOoyalaPlayer notifications and you have a property
// like `@property OOOoyalaPlayer *player;`
if ([notification.name isEqualToString:OOOoyalaPlayerStateChangedNotification]) {
  NSNumber *state = notification.userInfo[@"newState"];
  if (state.intValue == OOOoyalaPlayerStateReady) {
    NSArray *audioTracks = [self.player availableAudioTracks];
    // lets assume audio tracks array has 2 different tracks and we want to select the second one
    [self.player setAudioTrack:audioTracks[1]];
  }
}
