Public constructors

DefaultAssetLoaderFactory

public DefaultAssetLoaderFactory(Context context, BitmapLoader bitmapLoader)

Creates an instance with the default Clock and Codec.DecoderFactory.

For multi-picture formats (e.g. gifs), a single image frame from the container is loaded. The frame loaded is determined by the BitmapLoader implementation.

Parameters
`Context context`	The `Context`.
`BitmapLoader bitmapLoader`	The `BitmapLoader` to use to load and decode images.

DefaultAssetLoaderFactory

public DefaultAssetLoaderFactory(
    Context context,
    Codec.DecoderFactory decoderFactory,
    Clock clock
)

Creates an instance.

Uses DataSourceBitmapLoader to load images, setting the inPreferredColorSpace to SRGB when possible.

Parameters
`Context context`	The `Context`.
`Codec.DecoderFactory decoderFactory`	The `Codec.DecoderFactory` to use to decode the samples (if necessary).
`Clock clock`	The `Clock` to use. It should always be `DEFAULT`, except for testing.

DefaultAssetLoaderFactory

public DefaultAssetLoaderFactory(
    Context context,
    Codec.DecoderFactory decoderFactory,
    Clock clock,
    MediaSource.Factory mediaSourceFactory,
    BitmapLoader bitmapLoader
)

Creates an instance.

Parameters
`Context context`	The `Context`.
`Codec.DecoderFactory decoderFactory`	The `Codec.DecoderFactory` to use to decode the samples (if necessary).
`Clock clock`	The `Clock` to use. It should always be `DEFAULT`, except for testing.
`MediaSource.Factory mediaSourceFactory`	The `MediaSource.Factory` to use to retrieve the samples to transform when an `ExoPlayerAssetLoader` is used.
`BitmapLoader bitmapLoader`	The `BitmapLoader` to use to load and decode images.

Public methods

createAssetLoader

public AssetLoader createAssetLoader(
    EditedMediaItem editedMediaItem,
    Looper looper,
    AssetLoader.Listener listener,
    AssetLoader.CompositionSettings compositionSettings
)

Creates an AssetLoader instance.

Parameters
`EditedMediaItem editedMediaItem`	The `EditedMediaItem` to load.
`Looper looper`	The `Looper` that's used to access the `AssetLoader` after it's been created.
`AssetLoader.Listener listener`	The `Listener` on which the `AssetLoader` should notify of events.
`AssetLoader.CompositionSettings compositionSettings`	The `CompositionSettings`.

Returns
`AssetLoader`	An `AssetLoader`.
