AssetLoader (ExoPlayer library)

All Known Implementing Classes:

ExoPlayerAssetLoader, ImageAssetLoader, TextureAssetLoader
```
@Deprecated
public interface AssetLoader
```
Deprecated.
com.google.android.exoplayer2 is deprecated. Please migrate to androidx.media3 (which contains the same ExoPlayer code). See the migration guide for more details, including a script to help with the migration.

Provides media data to a Transformer.
The output samples can be encoded or decoded.
Only audio and video samples are supported. Both audio and video tracks can be provided by a single asset loader, but outputting multiple tracks of the same type is not supported.
An asset loader is responsible for removing audio or video if requested.
If slow motion flattening is requested, the asset loader should flatten the video track for media containing slow motion markers. This is usually done prior to decoding. The audio samples are flattened after they are output by the AssetLoader, because this is done on decoded samples.
