ohos.agp.components.Component

ohos.agp.components.textureprovider.TextureProvider

public class TextureProvider
extends Component

Provides a TextureHolder that can be used for video playback.

TextureProvider is a basic component that can be used in scenarios where fast playback is required, for example, video playback. Unlike SurfaceProvider, TextureProvider does not create an independent window and is more like a common component.

Currently, TextureProvider provides methods for setting rotation and alpha value.
