com.castlabs.android.player.SingleControllerPlaylist

All Implemented Interfaces:
  `Playlist`

public class SingleControllerPlaylist extends PlayerController implements Playlist
`Playlist` implementation. As the Class name suggests, this Playlist implementation relies in the usage of a single `PlayerController`, which is the `SingleControllerPlaylist` itself. This implementation allows for multiple `PlayerConfigs` to be loaded and played in sequential order. You can start playback with one of the open methods. Several Playlist manipulation operations are available, such as `addItem(PlayerConfig)`, `swap(PlayerConfig, PlayerConfig)`, or `removeItem(PlayerConfig)`. Note that these APIs receive `PlayerConfig` objects, which should be contained in the Playlist. IE. be present in `getPlaylist()`. The playlist might apply some generic configuration to the items passed to `open(Parcelable...)`. This implies that the items in the playlist *will be different instances*. You should also register a `SingleControllerPlaylist.PlaylistListener` in the constructor to get Playlist-specific events, such as when a Playlist item change occurs. The current Playlist can be obtained with `getPlaylist()` and the current item with `getCurrentItem()`. The SingleControllerPlaylist operates on `PlayerConfig` objects. In order to use the `SingleControllerPlaylist` you should explicitly create it through its `constructor`. And, if you're using a `PlayerView`, set it with the `PlayerView.setPlayerController(PlayerController)` in your `Activity`.onCreate(Bundle) method. The playlist supports mixed clear-protected items where all protected items have the same `Drm` type. Note that initial DRM configuration shall be set `setInitialDrmConfiguration(DrmConfiguration)` when using dynamic playlist with mixed items and starting playlist with clear item followed by at least one protected.

  - ### open

    public void open(@NonNull Bundle bundle)
    Description copied from class: `PlayerController`
    This method takes a `Bundle` and extracts the information to create a `PlayerConfig` from the bundle. The following bundle keys are queried to create the playback state: The following keys will be checked:
    - `SdkConsts.INTENT_URL` expects a String (mandatory)
    - `SdkConsts.INTENT_START_PLAYING` expects a Boolean (default: true)
    - `SdkConsts.INTENT_POSITION_TO_PLAY` expects a Long (default: 0)
    - `SdkConsts.INTENT_DRM_CONFIGURATION` expects a `DrmConfiguration` (default: null)
    - `SdkConsts.INTENT_AUDIO_TRACK_GROUP_IDX` expects a `Integer` (default: 0 to play the first track)
    - `SdkConsts.INTENT_SUBTITLE_TRACK_GROUP_IDX` expects a `Integer` (default: -1 to disable subtitles)
    - `SdkConsts.INTENT_CONTENT_TYPE` expects a `Integer` (default: `SdkConsts.CONTENT_TYPE_UNKNOWN` to auto-detect). Allowed values are one of `SdkConsts.CONTENT_TYPE_UNKNOWN`, `SdkConsts.CONTENT_TYPE_DASH`, `SdkConsts.CONTENT_TYPE_HLS`, `SdkConsts.CONTENT_TYPE_SMOOTHSTREAMING`, or `SdkConsts.CONTENT_TYPE_MP4`
    - `SdkConsts.INTENT_AUDIO_VOLUME` expects a `Float` with a value 0 <= value <= 1
    - `SdkConsts.INTENT_SECONDARY_DISPLAY` expects a `Integer` and defaults to the value of `PlayerController.getSecondaryDisplay()`
    - `SdkConsts.INTENT_HD_CONTENT_FILTER` expects a `Integer` and defaults to the value of `PlayerSDK.PLAYBACK_HD_CONTENT`
    - `SdkConsts.INTENT_VIDEO_SIZE_FILTER` expects a `Point` and defaults to the value of `PlayerSDK.VIDEO_SIZE_FILTER`
    - `SdkConsts.INTENT_VIDEO_CODEC_FILTER` expects a `Integer` and defaults to the value of `PlayerSDK.VIDEO_CODEC_FILTER`
    - `SdkConsts.INTENT_ENABLE_LOOPING` expects a `Boolean` and if true, enables looping
    - `SdkConsts.INTENT_ANALYTICS_DATA` expects a `AnalyticsMetaData` object and is required if you are using one of the analytics plugins
    - `SdkConsts.INTENT_BUFFER_CONFIGURATION` expects a `BufferConfiguration` object and can be used to teak the player buffer
    - `SdkConsts.INTENT_ABR_CONFIGURATION` expects a `AbrConfiguration` object and can be used to teak the players ABR behaviour
    - `SdkConsts.INTENT_USER_ID` expects a `String`
    - `SdkConsts.INTENT_LIVE_CONFIGURATION` expects a `LiveConfiguration` object and is used to tweak live-related params
    In addition, you can use `SdkConsts.INTENT_QUERY_PARAMS_BUNDLE` and `SdkConsts.INTENT_HEADER_PARAMS_BUNDLE` to configure and add query and header parameters that will be send with each request. This can for example be used to add tokens when remote resources are requested. In both cases, the bundle needs to reference another `Bundle` instance that is then used as a key/value store for the query or header parameters.

    You can also use `SdkConsts.INTENT_SUBTITLE_BUNDLE_ARRAYLIST` to side-load additional subtitle tracks through the bundle. Use the key to store an `ArrayList` of `Bundle` instances that specify side loaded tracks. Use `intent.putParcelableArrayListExtra(SdkConsts.INTENT_SUBTITLE_BUNDLE_ARRAYLIST, ...);` to add the list of bundles with the subtitle track information. A full example of this looks like:

         ArrayList<Bunde> subtitles = new ArrayList<>();
         Bundle bundle = new Bundle();
         bundle.putString(SdkConsts.INTENT_SUBTITLE_URL, "https://my.com/subtitle.ttml");
         bundle.putString(SdkConsts.INTENT_SUBTITLE_MIME_TYPE, SdkConsts.MIME_TYPE_TTML);
         bundle.putString(SdkConsts.INTENT_SUBTITLE_LANGUAGE, "en");
         bundle.putString(SdkConsts.INTENT_SUBTITLE_NAME, "Side-loaded");
         subtitles.add(bundle);
         intent.putExtra(SdkConsts.INTENT_SUBTITLE_BUNDLE_ARRAYLIST, subtitles);

    Overrides:

  - ### seekWith

    public void seekWith(long offsetUs)
    Sets the player to the new position by applying the offset to the current position i.e. with the negative offset the playback goes backward and with the positive one goes forward. If necessary the playback may go to the previous or next item in the playlist with the calculated playback offset as following: previous item position is previous_item_duration + (current_item_position + offset) and next item position is current_item_position + offset - current_item_duration. In case of seeking within the first or the last item in the playlist then the playback position is clipped to either zero or last item duration correspondingly.
    Overrides:
      `seekWith` in class `PlayerController`
    Parameters:
      `offsetUs` - The offset to be applied to the current position
