Public constructors

DefaultAssetLoaderFactory

public DefaultAssetLoaderFactory(
    Context context,
    boolean forceInterpretHdrAsSdr,
    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.
boolean forceInterpretHdrAsSdr	Whether to apply HDR_MODE_EXPERIMENTAL_FORCE_INTERPRET_HDR_AS_SDR.
BitmapLoader bitmapLoader	The BitmapLoader to use to load and decode images.

DefaultAssetLoaderFactory

public DefaultAssetLoaderFactory(
    Context context,
    Codec.DecoderFactory decoderFactory,
    boolean forceInterpretHdrAsSdr,
    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).
boolean forceInterpretHdrAsSdr	Whether to apply HDR_MODE_EXPERIMENTAL_FORCE_INTERPRET_HDR_AS_SDR.
Clock clock	The Clock to use. It should always be DEFAULT, except for testing.

DefaultAssetLoaderFactory

public DefaultAssetLoaderFactory(
    Context context,
    Codec.DecoderFactory decoderFactory,
    boolean forceInterpretHdrAsSdr,
    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).
boolean forceInterpretHdrAsSdr	Whether to apply HDR_MODE_EXPERIMENTAL_FORCE_INTERPRET_HDR_AS_SDR.
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
)

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.

Returns
AssetLoader	An AssetLoader.
